The Vitamin That Quadruples Weight Loss

Taking vitamin D supplements can significantly increase weight loss, according to a recent study.

People who took vitamin D supplements had over four times the weight loss as those that did not, researchers found.

obese

Vitamin D also doubled the number of inches taken off their waistlines.

Low levels of vitamin D is repeatedly linked to being overweight and obese.

Almost 40 percent of obese people are deficient in vitamin D.

The study included 400 obese and overweight people with vitamin D deficiency.

They were put on a low-calorie diet and split into three groups.

One group took 25,000 IU of vitamin D per month, the second took 100,000 IU of vitamin D per month and the control group took none.

Six months later the results showed that both vitamin D groups had lost more weight than those who were not taking the vitamin.

Those taking 100,000, or around 3,000 IU per day, had 12 pounds of weight loss.

People taking 25,000 IU, or around 800 IU per day, lost 8 pounds.

In comparison, those only following the calorie restricted diet had just 2.6 pounds of weight loss over the six months.

The study’s authors write:

“The present data indicate that in obese and overweight people with vitamin D deficiency, vitamin D supplementation aids weight loss and enhances the beneficial effects of a reduced-calorie diet.”

Measurements of dieters’ waistlines also revealed vitamin D had had an effect.

Those taking 100,000 IU lost an average of two inches from their waistline compared to just over 1 inch in the control group.

The researchers conclude:

“All people affected by obesity should have their levels of vitamin D tested to see if they are deficient, and if so, begin taking supplements.”

Gut Bacteria is Key Factor in Childhood Obesity



Summary:
Scientists suggest that gut bacteria and its interactions with immune cells and metabolic organs, including fat tissue, play a key role in childhood obesity.


New information published by scientists at Wake Forest Baptist Health suggests that gut bacteria and its interactions with immune cells and metabolic organs, including fat tissue, play a key role in childhood obesity.

“The medical community used to think that obesity was a result of consuming too many calories. However, a series of studies over the past decade has confirmed that the microbes living in our gut are not only associated with obesity but also are one of the causes,” said Hariom Yadav, Ph.D., lead author of the review and assistant professor of molecular medicine at Wake Forest School of Medicine, part of Wake Forest Baptist.

In the United States, the percentage of children and adolescents affected by obesity has more than tripled since the 1970s, according to the Centers for Disease Control and Prevention. Obesity is increasing at 2.3% rate each year among school-aged children, which is unacceptably high and indicates worrisome prospects for the next generation’s health, the article states.


Yadav’s manuscript, published in the current issue of the journal Obesity Reviews, reviewed existing studies (animal and human) on how the interaction between gut microbiome and immune cells can be passed from mother to baby as early as gestation and can contribute to childhood obesity.


The review also described how a mother’s health, diet, exercise level, antibiotic use, birth method (natural or cesarean), and feeding method (formula or breast milk) can affect the risk of obesity in her children.

“This compilation of current research should be very useful for doctors, nutritionists and dietitians to discuss with their patients because so many of these factors can be changed if people have enough good information,” Yadav said. “We also wanted to identify gaps in the science for future research.”

In addition, having a better understanding of the role of the gut microbiome and obesity in both mothers and their children hopefully will help scientists design more successful preventive and therapeutic strategies to check the rise of obesity in children, he said.

This Common Food Doubles Weight Loss

The food signals the body to start burning fat and stop storing it.

Around 3 servings of yoghurt each day can double weight loss, research finds.

People in the study who ate yoghurt lost twice as much body fat as those that did not.

Yoghurt is rich in calcium, which is thought to aid weight loss.

Calcium signals the body to start burning fat and stop storing it.

Dieters taking calcium lost 81 percent more belly fat.

Belly fat is particularly dangerous, with strong links to heart disease, stroke and some types of cancer.

Professor Michael Zemel, the study’s first author, said:

“Not only did yogurt help the study participants lose more weight–the average weight loss was 13 pounds–they were about twice as effective at maintaining lean muscle mass.
This is a critical issue when dieting — you want to lose fat, not muscle.
Muscle helps burn calories, but it is often compromised during weight loss.”

The study included 34 obese people who were all put on a calorie-restricted diet.

Their diet was restricted by 500 calories each day.

Half of them were given 500mg of calcium per day as a supplement, while the other group were given 1,100mg plus three servings of low-fat yoghurt.

The results showed that those taking the higher dose of calcium lost 22 percent more weight, 61 percent more body fat and 81 percent more belly fat.

Professor Zemel said:

“The moral of the calcium story is to not dump dairy when you’re dieting.
Not only is it critical to keep your calcium levels high so you won’t lose bone density, it will also help you maintain your muscle mass and increase your fat loss.
A diet rich in low fat dairy foods, like yogurt, can help make your weight loss efforts easier.”

What are the best breakfasts for losing weight?

Some people believe that breakfast is the most important meal of the day and that eating breakfast increases weight loss. But is this true? And, if so, which are the best breakfast foods for weight loss?

There is little evidence to support the idea that eating breakfast can increase weight loss. Breakfast is just another meal. That said, eating breakfast can give a person energy for the day. This may reduce the risk of overeating and, in this way, support weight loss efforts.

This article explores the best breakfast foods to eat to aid weight loss. It also discusses breakfast options to suit vegetarian, vegan, and restricted diets. Read on to learn all there is to know about eating breakfast and losing weight.

Breakfast food tips

To get the most out of breakfast, it is best to eat nutrient dense foods. These foods offer more nutritional value per calorie, which may help a person feel fuller longer.

Here are some breakfast food tips that may support weight loss:

Eat fiber-rich foods

People who regularly eat fiber-rich breakfasts may have less visceral fat and inflammation.
People trying to lose weight may benefit from eating fiber-rich foods for breakfast and throughout the day.

A 2015 study found that diets rich in fiber helped people lose more weight and improved symptoms of metabolic syndrome. Metabolic syndrome is a risk factor for diabetes.

Other studies link fiber to better health and more weight loss. For example, a 2012 study found that adolescents who ate more fiber had less visceral fat and less inflammation.

Eat more protein

Eating more protein for breakfast or at any other time of day may support weight loss.

Numerous studies link higher protein diets to more weight loss. A 2014 analysis suggests that protein may help people feel fuller, reducing overeating. People may also burn more calories when they eat protein.

Protein-rich foods are generally rich in other nutrients, allowing a person to get a wide range of nutrients without consuming lots of calories.

Avoid high calorie options

Try to avoid foods that are high in calories and low in nutrients. Reducing calorie intake at breakfast time and throughout the day may help a person lose weight.

To cut down on calories, avoid adding sugar to breakfast foods. A healthy oatmeal breakfast can become a sugar-laden, high calorie meal when a person adds lots of brown sugar. Select cereals that contain less sugar and avoid pancakes and pastries that contain lots of sugar.

Avoid sugary drinks

Be mindful of the role of drinks in calorie content. A glass of orange juice typically contains more than 100 calories but offers little nutritional value. Opt for eating the whole fruit rather than drinking juices.

Eat whole foods

Eating whole foods instead of processed foods may help a person lose weight. Try replacing white bread, pasta, and bagels with whole grain options.

Whole grain offers more nutritional value and may reduce the risk of some types of heart disease. Because whole grains are rich in fiber, they may support weight loss and reduce constipation.

Should you eat breakfast?

With interest in intermittent fasting increasing, some people are now opting to skip breakfast altogether. But does skipping breakfast support weight loss?

Not eating breakfast may support weight loss because it means a person goes longer without consuming calories, which may lead to a lower total calorie intake throughout the day.

However, skipping breakfast may not support weight loss for everyone. For some people, skipping breakfast leads to overeating at lunchtime. In this way, skipping breakfast may lead to higher overall calorie consumption, undermining weight loss.

Research around breakfast and weight loss is inconclusive. A 2019 BMJ meta-analysis and systematic review suggests that skipping breakfast may support weight loss. Examining 13 trials, researchers found that not eating breakfast offered modest decreases in weight.

However, the study’s authors also note that the data is not strong. Other factors might account for the difference. Scientists need to do more research to fully understand whether avoiding breakfast is an effective weight loss strategy.

Breakfast foods for vegans

Peanut butter on toast is a healthful breakfast choice for vegans trying to lose weight.
As for all people, it is essential for people who follow a vegan diet to consume sufficient protein. Consuming protein helps people to feel full, which may support weight loss.

Vegan breakfast foods may be a healthful option for anyone wanting to limit meat consumption or add variety to their diet. Also, eating more vegetables increases a person’s fiber and nutrient intake.

Many vegan breakfast options are rich in protein, fiber, and other nutrients. Here are some vegan breakfast foods to try:

  • vegan scramble (using tofu instead of eggs) and kale, broccoli, or spinach
  • peanut or almond butter on whole grain toast
  • oatmeal with blueberries, strawberries, or raspberries and an optional teaspoon of honey
  • whole grain cereal with soy or almond milk
  • avocado toast on whole wheat bread, seasoned with lemon juice and sea salt
  • tofu omelet
  • vegan BLT made from soy bacon, lettuce, tomato, and whole grain buns
  • mixed nuts
  • rolled oats with peanut butter
  • smoothie with avocado, banana, frozen berries, and a teaspoon of honey

Breakfast foods for vegetarians

Vegetarians can choose from a wide variety of delicious breakfast foods. Adding dairy products makes it easy to get plenty of protein to support weight loss.

A 2011 study compared the diet of vegetarians to nonvegetarians. Researchers found that vegetarian diets were more nutritionally dense. This may be because vegetarians eat more fruits and vegetables than meat eaters. The study’s authors also suggest that a vegetarian diet may support weight loss.

Here are some vegetarian breakfast ideas:

  • whole grain cereal with 1% milk
  • Greek yogurt with berries
  • plain vanilla yogurt with bananas
  • two slices of white cheddar cheese with a handful of mixed nuts
  • hard boiled egg sprinkled with salt
  • avocado with cottage cheese and hot sauce
  • poached eggs on whole grain toast
  • scrambled eggs with hot sauce instead of cheese or salt

Breakfast foods for meat eaters

While meat is high in many nutrients, it is also a high calorie food due to its fat content. Lean meats and poultry contain less fat and calories than red meats, so choosing these types of meat is a good option for meat eaters hoping to lose weight.

Reducing the amount of meat in each meal and replacing it with nutrient-rich, high fiber vegetables may also help.

The following meals can support healthy weight loss:

  • grilled chicken sandwich with lettuce on whole grain bread
  • Canadian bacon with yogurt or eggs
  • turkey sausage scramble with lots of vegetables

Breakfast for people with dietary restrictions

Having allergies or an underlying health condition need not affect a person’s enjoyment of breakfast. There are plenty of alternatives available.

Here are some breakfast options for people with dietary restrictions:

Food allergies

Many people have food allergies or sensitivities to lactose, nuts, and eggs, which many breakfast foods contain. Fortunately, there are many substitute options available:

  • Lactose intolerance: Lactose free milk and milk substitutes, such as almond milk, can be good options for people with lactose intolerance.
  • Nut allergies: Lentils, chia seeds, and quinoa can be healthful options for people with nut allergies.
  • Egg allergies: People who cannot eat eggs should consider lean meats, nut butter, and nuts instead.
  • Celiac disease

For people with celiac disease or a gluten intolerance, finding breakfast options that do not contain gluten is essential.

Many food stores sell gluten free versions of common breakfast items, including:

  • bagels
  • pancakes
  • cereals
  • Another gluten free breakfast idea involves serving high protein foods, such as eggs or lean meats, with wilted spinach and cooked tomatoes.

Diabetes
People with diabetes can eat hard boiled eggs for breakfast to manage their blood sugar levels.
People with diabetes must keep their blood sugar levels consistent. Skipping breakfast may not be healthful for people with diabetes, particularly if they take medication for their condition. People who take medication for their diabetes typically need to consume some carbohydrate to manage their blood sugar levels.

Here are some breakfast options for people with diabetes:

  • scrambled eggs with wilted spinach
  • hard boiled eggs
  • a handful of nuts
  • lean meats with spinach or kale

Summary
Breakfast habits can support weight loss but how this works varies from person to person. Eating breakfast may aid weight loss for some people as they stay fuller for longer, which prevents snacking during the day. For others, skipping breakfast supports weight loss because it leads them to consume fewer calories overall.

Losing weight requires a person to burn fewer calories than they eat. To sustain weight loss, a person must stick to a reduced calorie diet and pair this diet with more activity. To make sustainable dietary changes, it is vital that a person finds healthful foods they enjoy eating.

Highly restrictive diets are often difficult to follow. Instead, incorporate a few treats and find nourishing, low calorie foods that taste good. A dietitian or doctor can help a person develop the right meal plan for their needs

Pretty Much Everything We Eat Is Full Of Sugar, And That’s A Major Problem

Additives sure aren’t adding to your health.

A frighteningly large portion of the calories and sugar North Americans eat comes from ultra-processed foods, which are tinkered with even more than regularly processed foods and may contribute to serious health issues like Type 2 diabetes, according to a new study.

Researchers from Tufts University and the University of Sao Paulo in Brazil found that ultra-processed foods are responsible for almost 60 percent of all the calories North Americans consume and about 90 percent of all added sugars they eat.

“The content of added sugars in ultra-processed foods was eightfold higher than in processed foods and fivefold higher than in unprocessed or minimally processed foods and processed culinary ingredients grouped together,” they write in the study published Wednesday in BMJ Open.

Added sugars should make up only about 10 percent of a person’s total caloric intake, the researchers note – however, they found that more than 80 percent of North Americans typically exceed this recommended limit.

Processed foods generally have added oils and salt. Ultra-processed foods are different because they’re enhanced with other additives, including colors, artificial flavoring and sweeteners, the study says.

Researchers say the top ultra-processed foods that North Americans consume are:

  • Breads
  • Cakes, cookies and pie
  • Salty snacks
  • Frozen meals
  • Soft drinks and fruit drinks
  • Pizza
  • Ice cream
  • French fries

For the study, researchers conducted at-home interviews and health examinations with 9,317 people of all ages, who also provided them with information about what they ate for a 24-hour period. The researchers say their study is the first to examine the relationship between ultra-processed foods and sugar intake in the U.S.

Eating excess amounts of added sugars is “most likely” contributing to health issues such as obesity, high blood pressure and coronary heart disease, the study warns.

The best thing to do is to entirely cut out these foods from your diet, the researchers say. That may sound easier said than done – and maybe even impossible, especially when life gets really busy. One way to do this is to avoid replacing water, pasteurized fresh milk and freshly squeezed fruit juices by soft drinks or flavored fruit drinks, said Professor Carlos A. Monteiro, one of the study’s authors.

Preparing at least some fresh foods at home rather than buying a lot of packaged meals will help decrease sugar intake, Monteiro added. And when you do buy packaged foods, be sure to look at the ingredient labels – even items like deli meats often contain sugar.

It’s Not Your Fault That You Eat So Much Sugar

Consumers don’t even want all this cloying sweetness. Manufacturers made the decision for them.

Consumers’ most common complaint about taste? “Too sweet.”

Americans tend to associate our health problems with sin. It’s hard to find a health story in the press that doesn’t blame greed and lack of willpower for our ongoing epidemics of obesity and diabetes as well as a recent upturn in the rate of heart disease. But the problems stem more from a greedy food industry than from any weakness in consumers. Our supermarket shelves are filled with items made with cheap ingredients, especially sugar and corn syrup, whether people want it or not.

A fascinating new study out of the Monell Chemical Senses Center in Philadelphia showed that among 400,000 food reviews on Amazon.com, the primary complaint was that food was too sweet. People used terms like “syrupy, overwhelmingly or cloyingly sweet,” said behavioral geneticist Danielle Reed, who led the research. She and her colleagues used a machine- learning program to sort through the thousands of reviews covering 67,553 products.

The finding was a surprise; she had designed the study to add to her body of work on the way people vary in the perception of bitterness. Genetic differences make some people much more sensitive to bitter tastes than others, and this can affect whether we love or hate vegetables such as broccoli and kale. She was surprised, she said, that on Amazon reviews, consumers rarely complained about bitterness, or saltiness for that matter. They complained about sweetness. Manufacturers may think they are sweetening things to suit a common taste, in which case they are getting it wrong – but the market is full of oversweetened foods, so the manufacturers mostly don’t lose customers to better-tasting competitors.

Or the problem may be that manufacturers are trying to use the cheapest possible ingredients in a way that consumers will still tolerate. Sugar is cheap, and corn syrup even cheaper. In his book “The Omnivore’s Dilemma,” author Michael Pollan recounts the way the introduction of corn syrup in the late 20th century tempted manufacturers add as much as possible to many processed foods and to lure consumers with giant sodas and other supersized products that felt like bargains but came with hidden costs. Later, the medical dogma that fat was deadly lead to an explosion of extremely sweet low-fat products as well.

However we got here, it’s clear that the empty calories are contributing to epidemics of obesity in the U.S. and elsewhere. The food police should rethink chastising consumers and turn their attention on the true culprits who are dishing it out.

Keen Sense of Smell Linked to Longer Life

(Reuters Health) – Older adults with a poor sense of smell may die sooner than their counterparts who have keen olfactory abilities, a U.S. study suggests.

Researchers asked 2,289 adults, ages 71 to 82, to identify 12 common smells, awarding scores from zero to as high as 12 based on how many scents they got right. When they joined the study, none of the participants were frail: they could walk a quarter mile, climb 10 steps, and independently complete daily activities.

During 13 years of follow-up, 1,211 participants died.

Overall, participants with a weak nose were 46 percent more likely to die by year 10 and 30 percent more apt to pass away by year 13 than people with a good sense of smell, the study found.

“The association was largely limited to participants who reported good-to-excellent health at enrollment, suggesting that poor sense of smell is an early and sensitive sign for deteriorating health before it is clinically recognizable,” said senior study author Dr. Honglei Chen of Michigan State University in East Lansing.

“Poor sense of smell is likely an important health marker in older adults beyond what we have already known about (i.e., connections with dementia, Parkinson’s disease, poor nutrition, and safety hazards),” Chen said by email.

People who started out the study in excellent or good health were 62 percent more likely to die by year 10 when they had a poor sense of smell than when they had a keen nose, researchers report in the Annals of Internal Medicine.

But smell didn’t appear to make a meaningful difference in mortality rates for people who were in fair to poor health at the start of the study.

With a poor sense of smell, people were more likely to die of neurodegenerative and cardiovascular diseases, but not of cancer or respiratory conditions.

Poor sense of smell may be an early warning for poor health in older age that goes beyond neurodegenerative diseases that are often signal the beginning of physical or mental decline, the results also suggest.

Dementia or Parkinson disease explained only 22 percent of the higher death risk tied to a poor sense of smell, while weight loss explained just six percent of this connection, researchers estimated. That leaves more than 70 percent of the higher mortality rates tied to a weak nose unexplained.

The connection between a poor sense of smell and mortality risk didn’t appear to differ by sex or race or based on individuals’ demographic characteristics, lifestyle, and or chronic health conditions.

One limitation of the study is that the older adult participants were relatively functional, making it possible results might differ for younger people or for frail elderly individuals, the study team writes.

Researchers also only tested smell at one point in time, and they didn’t look at whether changes in olfactory abilities over time might influence mortality. Researchers also lacked data on certain medical causes of a weak nose such as nasal surgery or chronic rhinosinusitis that are not related to aging.

“The take-home message is that a loss in the sense of smell may serve as a bellwether for declining health,” said Vidyulata Kamath of the Johns Hopkins University School of Medicine in Baltimore, co-author of an accompanying editorial.

“As we age, we may be unaware of declining olfactory abilities,” Kamath said by email. “Given this discrepancy, routine olfactory assessment in older adults may have clinical utility in screening persons at risk for illness, injury or disease for whom additional clinical work-up and/or intervention may be warranted.”

Humans Smell With Their Tongues, Scientists Discover

The receptors that dot our noses and help us to smell also populate our tongues, according to a new study. Researchers at the Monell Chemical Senses Center have discovered working olfactory (smell) receptors in the taste-sensing cells on the papillae of the tongue. The findings were published in the journal Chemical Senses.
It is thought that the systems that enable us and other mammals to taste and smell are separate, and our brains combine this information so we can experience flavor. While the tongue deals with whether food is salty, sweet, sour, bitter, or umami, our noses provide more detail from smells.
As such, the study calls into question whether the mixing of smell and taste first happens in the brain. Instead, it provides evidence suggesting the process that creates flavor may first happen in the tongue.
However, Dr. Mehmet Hakan Ozdener, senior study author and a cell biologist at Monell Chemical Sense Center, stressed to The Guardian: “I am not saying that [if you] open your mouth, you smell.”
He said in a statement: “Our research may help explain how odor molecules modulate taste perception. The presence of olfactory receptors and taste receptors in the same cell will provide us with exciting opportunities to study interactions between odor and taste stimuli on the tongue.”
To arrive at their conclusion, scientists used genetic and biochemical tests to study human taste cells in a lab. They also used calcium imaging, which showed taste cells react to smells similarly to cells which pick up odor.
Ozdener was inspired to carry out the research after his 12-year-old son asked him if snakes waggle their tongues out of their mouths to smell.
The team hopes the research could help to combat the obesity epidemic, by creating flavor without the need for heaps of delicious yet unhealthy ingredients.
“This may lead to the development of odor-based taste modifiers that can help combat the excess salt, sugar, and fat intake associated with diet-related diseases such as obesity and diabetes,” he said.
The team also hopes their work will shed light on the little-understood olfactory system, which contains around 400 different receptors which enables us to smell.
Earlier this week, a separate team published a study showing humans use their sense of smell to navigate space. The scientists behind the study published in the journal Neuron created a “smellscape” in a room featuring the scent of pine and banana, which participants moved around.

Household Cleaners May Alter Kids’ Gut Flora And Contribute To Being Overweight, Says Study

Commonly used household disinfectants could increase the risk of young children becoming overweight by altering the makeup of their gut bacteria during the first few months of life, a study suggests.

The study, published Monday in the Canadian Medical Association Journal, analyzed the gut flora of 757 infants at age three to four months and their body mass index, or BMI, at one and three years old, looking at exposure to disinfectants, detergents and eco-friendly products used in the home.

Anita Kozyrskyj, professor of pediatrics at the University of Alberta, is shown in a handout photo. The high use of household disinfectant cleaners is changing the gut flora in babies, leading to them becoming overweight as three-year-olds.

“We found that infants living in households with disinfectants being used at least weekly were twice as likely to have higher levels of the gut microbes Lachnospiraceae at age three to four months,” said principal investigator Anita Kozyrskyj, a professor of pediatrics at the University of Alberta.

Lachnospiraceae is one of many non-pathogenic bacteria that naturally inhabit the human gut.

“When they were three years old, their body mass index was higher than children not exposed to heavy home use of disinfectants as an infant,” she added.

Researchers from across Canada looked at data on microbes in infant fecal matter among children enrolled in the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort. They used World Health Organization growth charts for BMI scores.

Associations with altered gut flora in babies three to four months old were strongest for frequent use of household disinfectants such as multi-surface cleaners, which showed higher levels of Lachnospiraceae.

Kozyrskyj said researchers also found there was a greater increase in levels of those bacteria in children whose parents reported more frequent cleaning with disinfectants.

“As the microbiome develops over the first year of life, these microbes increase in their abundance. So it was a matter of dose,” she said in an interview, noting that studies of piglets have found similar changes in the animals’ gut microbiome when they were exposed to aerosol disinfectants in their enclosures.

However, the same association was not found with detergents or eco-friendly cleaners, the CHILD study found. Babies living in households that used eco-friendly cleaners had different microbiota and were less likely to be overweight as toddlers.

 

“Those infants growing up in households with heavy use of eco cleaners had much lower levels of the gut microbes Enterobacteriaceae (a family of bacteria that includes E. coli). However, we found no evidence that these gut microbiome changes caused the reduced obesity risk,” Kozyrskyj said.

One reason could be that the use of eco-friendly products may be linked to healthier overall maternal lifestyles and eating habits, contributing in turn to the healthier gut microbiomes and weight of infants.

“Antibacterial cleaning products have the capacity to change the environmental microbiome and alter risk for child overweight,” write the authors. “Our study provides novel information regarding the impact of these products on infant gut microbial composition and outcomes of overweight in the same population.”

There are many findings that point to a possible causative role for disinfectants in altering gut flora and subsequently leading to a higher childhood BMI, said Kozyrskyj, noting that in studies of mice, Lachnospiraceae has been shown to cause insulin resistance and increased fat storage.

“I would be comfortable in saying the high use of disinfectants had a contributory role … My advice would be to not overuse them,” she said.
“Some people might say maybe go for an alternative, go for the eco product instead of the disinfectants as a cleaning agent.”

In a related CMAJ commentary, epidemiologists Dr. Noel Mueller and Moira Differding of the Johns Hopkins Bloomberg School of Public Health write: “There is biologic plausibility to the finding that early-life exposure to disinfectants may increase risk of childhood obesity through the alterations in bacteria within the Lachnospiraceae family.”

They call for further studies “to explore the intriguing possibility that use of household disinfectants might contribute to the complex causes of obesity through microbially mediated mechanisms.”

Kozyrskyj agreed, saying there is a need for further research that classifies cleaning products by their ingredients, with an analysis of their potential individual effects.

11 Sneaky Things Other Than Food & Exercise That May Affect Your Weight

And how to make them work in your favor

The great recession

What do economics have to do with health? At most universities they’re not even in the same building! But it turns out that a dip in the economy can lead to a rise in our weight according to a study done by John Hopkins. Researchers found that from 2008 to 2012—the period known as the great recession—weight gain was strongly correlated with the rise in unemployment, increasing the risk of obesity by 21 percent. This makes sense as one of the first things to go when our budgets get tight are luxuries like health food and gym memberships, not to mention the loss of health insurance that often accompanies a job loss. However, it may help to remember that there are many low-cost or free ways to protect your health—and an investment in you is the best one you can make.

How high you are

No we’re not talking about the wave of pot legalization sweeping the country (although that probably would affect your weight too) but rather how high up you live. There’s a reason that Colorado is the both the slimmest and the steepest state in the nation. The altitude at which you live is strongly correlated with your weight, with each gain in altitude corresponding with a drop in weight, according to a study done by the U.S. Air Force. But don’t sell your beach-front property and head for the hills just yet—the effect can be balanced out by other factors known to prevent against obesity where you live, like outdoor greenery, strong social ties, and opportunities to go outside. Case in point: Hawaii is the third thinnest state in America, and it’s the definition of sea level.

 

It’s a generation thing

Ever wondered why your grandma never exercised a day in her life and yet wore a tiny wedding dress that you could never hope to fit into even though you run marathons? Some of it may be due to the difference in generations you were both born into. Bad news for young ‘uns: Millennials, Gen Y, and Gen X all need to eat less and exercise more to stave off obesity than their forefathers did, according to a study from York University. And it’s not just the fact that we have Netflix and take out at our fingertips. Rather, the researchers found that the average metabolism of both men and women has slowed, even after controlling for factors like disease, diet, and fitness. Why? We have no solid answers yet but in the meantime, if you’re under 40 at least you can take comfort that you’re not alone in your struggle.

That cursed smog

The effects of environmental pollutants go far beyond wheezing and sneezing. Rats exposed to highly polluted air were not only much more likely to become obese, according to a study done by Duke University, but also had a greater risk of heart disease, diabetes, and metabolic syndrome. And it’s not just limited to rodents. People who live close to roadways with a high level of air pollution are also more likely to gain weight, says a study from the University of Southern California. Unfortunately air pollution is likely not under your direct control but we can all work together to lobby for and implement clean-air policies where we live, making for both a healthier physical and celestial body.

Your thermostat

Our delightfully warm and cozy homes and offices might be partly responsible for our less-delightful expanding waistlines, say researchers in a study published in the journal Cell. The scientists found that regular exposure to mildly cold weather—as would have been normal in the days before programmable thermostats—helps the human body regulate a healthy weight. The chilly air seems to increase metabolism by making the body work harder to cope with the changing conditions. Some proponents of “cold therapy” take daily ice baths or “shiver walks” but you don’t have to be that extreme to see results, say the researchers. Just lowering your thermostat by a few degrees or turning the shower briefly to cold can help.

How many antibiotics you’ve taken

Antibiotics are one of the biggest miracles of modern medicine, no doubt about it. But those infection-fighting drugs may have unintended consequences. The more antibiotics a person takes during their lifetime, particularly during early childhood, the greater their risk of becoming obese, according to an NYU study. Researchers speculate that it has to do with killing healthy gut bacteria, decimating your microbiome along with the bad bugs, as good bacteria has been shown to help prevent weight gain. But if you were the kid with chronic ear infections, don’t fret, you can rebuild your good gut bacteria by taking a probiotic and eating plenty of fermented foods such as yogurt, kefir, sauerkraut, and kimchi.

Fido and Fifi

Owning a pet, particularly a dog, slashes the human companion’s risk of obesity, says the American Heart Association. Why? Dogs need to be walked daily and are often quite persistent, encouraging their owners to walk as well. But it’s not just the extra exercise, especially since 40 percent of dog owners confess to not walking their dog on a regular basis. The researchers add that petting an animal greatly reduces stress and depression, two other known risk factors for weight gain. So if you do have a dog, make sure to walk them daily, and in the meantime soak up all the snuggles, wet kisses, and purrs you can.

The number on your paycheck

Income is one of the biggest factors correlated with obesity, with poor Americans being three times more likely to be obese than richer ones, according to a study published in Nutrition Reviews. Low-income people are less likely to have access to supermarkets with fresh foods (often living in “food deserts”), less likely to have health insurance, and less likely to live in neighborhoods where exercise outdoors is encouraged or even safe. Fortunately this is one area we can all help improve by working to better conditions in our own neighborhoods or helping out others nearby.

Pesticides

Pesticides may help us grow stronger and more plentiful crops but many of the chemicals used in popular formulations are known “endocrine disruptors”: They interfere with your body’s metabolic systems. Pesticides hijack our metabolism by mimicking, blocking, or otherwise interfering with the body’s natural hormones, according to a report issued by The Endocrine Society. Regular exposure to pesticides through food was correlated with an increase risk of both obesity and diabetes. Buying all organic may be one solution but for many people that doesn’t fit in the budget. If money’s tight you can also decrease your pesticide load by avoiding, or only buying organic of, the “dirty dozen“, the most contaminated produce. Or you can always try growing some of your own fruits and vegetables. (Bonus: Gardening is great exercise!)

How many trees you can count from your window

Close proximity to parks, trails, and other types of green spaces is linked with lower body weight, according to research done by the American Diabetes Association. Being able to see, and more importantly walk to, greenery encouraged people to exercise more and made it feel, well, less like exercise. Parks make physical exertion feel like fun but even if you’re not using them to exercise, simply being in the presence of nature has been shown to reduce stress, lower weight and improve your health overall. The vast majority of Americans already live within walking distance of some type of park so get out there and explore your neighborhood.

All that stuff on the food label you don’t recognize

You already know that processed foods do no favors for your waistline but it turns out it’s not just the empty calories and trans fats doing the damage. Some of the most popular food additives are linked with weight gain and obesity, according to a study done by Georgia State University. Emulsifiers, which are added to most processed foods for texture and to extend shelf life, are one of the worst offenders as they interfere with good gut bacteria. But some artificial flavorings, artificial sweeteners, preservatives, and even the food packaging have also been linked in research to obesity.

Small Changes To Make That Can Have a MAJOR Impact on Health

Big changes like cutting out all carbs or training for a marathon are great—but you don’t have to remake yourself to have a dramatic impact on your health. Try a few of these baby steps to get you started in the right direction.

Add a fruit or veggie to every meal

Not ready to give up a bad habit yet? Start by creating an easy good-for-you habit instead. “Less than one in three individuals gets even two servings of fruits and vegetables per day,” says Erin Palinski-Wade, RD, CDE, LDN, CPT, author of 2 Day Diabetes Diet. “By adding one serving to each meal, you can get in at least three servings per day and be ahead of the curve. A half of a banana on your breakfast cereal, a small side salad with your sandwich at lunch, and adding 1/2 cup of cooked veggies into your pasta can pack in more fiber, antioxidants, and nutrients—all which have been found to reduce the risk of heart disease, type 2 diabetes, and even certain cancers.”

Work on your hips

“If you have a sedentary job, focus on some hip opening exercises to start and end your day,” suggests trainer Jonathan Hertilus, ACE, owner of BFF Bootcamp in Nutley, NJ. “For instance,” says Hertilus, “hip bridges can be done anywhere—even in bed—as soon as you wake up or right before you go to sleep.” Just a few minutes of hip exercises can do wonders to keep your back and core muscles engaged.

Lose a little weight

Setting a goal to lose 40 pounds or more to get out of the “overweight” category can be daunting. So aim for smaller, more attainable goals, which can make a big difference in your overall health. “Small steps can be very powerful,” says Jill Crandall, MD, professor of endocrinology at Albert Einstein College of Medicine and an attending physician at Montefiore Health System.” For people who are at increased risk for type 2 diabetes, which includes many adults who are overweight and have a family history of diabetes, modest changes can reduce the risk of developing diabetes by over 50 percent.” Dr. Crandall suggests focusing on losing about 7 percent of your overall weight—or about 15 pounds for a 200-pound person.

Lighten your load

Cleaning out your purse or backpack could go a long way toward preventing neck, back, and shoulder pain. When you are carrying things, balance your load, and avoid backpacks or purses with more than 10 percent of your body weight,” suggests Robert Hayden, DC, PhD, a chiropractor in Griffin, Georgia.

Be careful with condiments

You might want to take a second to consider before you slather your next salad in ranch dressing. “Ketchup, barbecue sauce, mayo, and salad dressings can all be a major source of calories, sodium, fat, and added sugar,” says Palinski-Wade. “Opt for condiments on the side, rather than on your meal and read those labels!”

Skimp on the sugar—and pump up your probiotics

More and more studies show that sugar wreaks havoc on your health, including slowing your metabolism, impairing brain function, and increasing your risk of heart disease and cancer. But there are other health issues you can keep at bay with a little less sugar and a little more healthy bacteria. “Decreasing intake of sugar and processed food as well as taking probiotics can help decrease yeast infections,” says Jessica Shepherd, MD, MBA, OB/GYN, director of minimally invasive gynecology at University of Illinois at Chicago.

Straighten up your sleep habits

A bad sleep posture could make for more aches and pains when you’re awake. “Most of us don’t really think much about posture while we are asleep—but really, posture while you are asleep is at least as important as when you are awake because the muscles that protect your joints are quite loose while you are asleep,” says Dr. Hayden. “I recommend sleeping in a side posture whenever possible. Make sure your pillow is firm and just high enough to keep your head level with the mattress so that your head is neither pushed up nor down. Use a body pillow to hug, throwing your upper arm and upper knee over the pillow so that the pillow supports the weight of the extremities while you are asleep. This prevents you from inducing torque into the lumbar spine and offloads the weight of the upper extremity from the structures at the base of the neck. This simple approach to rest keeps your body straight and as stress free as possible while you catch those zzzs.”

Drink half your weight in water

We should all be drinking more water, but the old saw about eight glasses of eight ounces of water doesn’t work for everybody. The better formula? “Take your weight in pounds and divide by two, and you will get the number of ounces of water you should drink every day,” says Mitzi Dulan, RD, founder of simplyFUEL. “Start your day with a big glass of ice water. Ice cold water can boost your metabolism slightly because it takes energy for your body to get it to room temperature—drink six glasses of 16 ounces of cold water and burn an extra 100 calories per day.”

Stop the midnight snacking

“Avoid eating after 8 p.m.,” says Dulan. “Often times, late-night eating is really boredom eating. This helps your body focus on burning the fat during the night instead of trying to work to digest the food you just ate before nodding off.”

Shut off your electronics an hour before bedtime

Those last hours before bed may seem like the perfect time to catch up on some work or binge watch a little of your favorite show, but experts say that the light emanating from your screens could be disrupting your sleep. That wavelength of light disrupts melatonin production, and tricks your body into thinking it’s daylight, according to Mark Buchfuhrer, MD, medical director of the Comprehensive Sleep Center at Good Samaritan Hospital in Los Angeles. The fix? Skip the screens and tuck into a good book, do relaxed stretching, or find another way to unwind in the last hour before your bedtime.

Trade refined carbs for whole grains

“Most people eat plenty of grains, but most Americans consume only one serving of whole grains per day,” says Palinski-Wade. “By swapping out a few refined grains for whole grains, you may reduce your waist circumference and reduce the risk of heart disease and diabetes. If you use white bread for a sandwich, switch to rye. If you like rice, opt for brown rice over white rice. A simple switch can add up significantly.”

Take breaks when you’re traveling

Whether you travel by car or plane, taking frequent breaks to walk and stretch is essential. When flying by air, it can reduce your risk of developing a dangerous blood clot in your leg, called a deep vein thrombosis. “I coach our patients who are driving long-distance to get out of the vehicle periodically and walk around it a few laps,” Dr. Hayden says. “Find a bumper that is the right height to put one foot on it. Step back about two feet, square the pelvis, and lean toward the foot that is on the bumper. This has the effect of a hurdler’s stretch, and it will help stretch those gluteals on which you have been sitting as well as the quadriceps and many of the extensor muscles in the back. Always stretch both sides—if you leave one side tight, you may find yourself walking in circles!”

Cut down on the cocktails

Those studies that show red wine’s positive health benefits may encourage us to raise a few more glasses, but there are really good reasons to limit your alcohol intake, including increased risk of high blood pressure and high cholesterol levels, and obesity. Cutting back on the booze can decrease the risk of many different kinds of cancer, including breast cancer, according to Dr. Shepherd. For women, one drink a day seems to be the healthy max, while men can have two.

Start squatting

“Everyone asks me to recommend one exercise that everyone can do to improve their overall health,” says Pat McGuinness, personal trainer at the MAX Challenge in Montclair, NJ, and regional director of programming for New York Sports Clubs. “My answer is always squats! Everyone can do them—modifications are easy—and leg muscles make up more than 60 percent of our total body composition, which means you get more bang for your buck!”

Walk for five minutes every hour at work

Studies have shown that a sedentary lifestyle can wreak havoc on your health. If you can’t get a standing desk to help you limit your time on your seat, make sure you take a five-minute walk break every hour. That can help you minimize the impact of sitting on your health, and ensure you get even more than the doctor-recommended 150 minutes of exercise per week. That can help you reduce the risk of type 2 diabetes, according to Dr. Crandall.

Swap soda for fruit-spiked water

Whether it’s diet or sugar-filled, study after study shows that soda isn’t the best beverage—unless you want to gain weight, increase your risk of developing diabetes, cancer, or heart disease, and reduce your bone density. But you don’t have to sacrifice flavor if you give up your soda. “Infuse water with fruit for a tasty alternative that’s sure to impress and refresh,” says McGuinness.
