5 Reasons You’re Not Losing Weight on a Vegan Diet – Nutrition … – Health.com


Most people tend to associate a vegan diet with being lean. And science backs that notion. In a study of 40,000 adults, Oxford University researchers found that meat-eaters had the highest BMIs; vegans had the lowest; and vegetarians and semi-vegetarians landed somewhere in-between. But throughout my years in private practice, I've worked with plenty of clients who did not lose weight after cutting out animal products. And some even gained weight. Here are five common reasons this happens, plus how to avoid themso you can reap both the health and weight-loss benefits of going vegan.
Healthy foodsincluding veggies, fruit, whole grains, nuts, seeds, and avocadocontain raw materials that either fuel the activity of your body's cells, or help maintain, heal, or regenerate tissue (such as hair, skin, immune cells, and muscle). But we don't require an unlimited supply of these nutrients. The amount your body needs is largely based on your age, sex, height, ideal body weight, and physical activity level. A young, tall, active man with a higher ideal weight, for example, requires larger portions than an older, petite, sedentary woman.
Often when I evaluate clients' food journals, I find that they aren't losing weight because their nutrient intake exceeds their needs. I had one female client who was eating a large aa bowl for breakfast that contained multiple servings of fruit, nut milk, nut butter, and seeds. She would then commute by car to work and sit at a desk all morning. While the bowl was chock-full of nutrition, it packed about three times what her body actually needed to keep her satiated until lunch.
Eating an adequate amount of protein is key for maintaining muscle mass, which helps keep your metabolism revved. It's possible to meet your daily protein needs on a plant-based diet. You just have to be strategic.
One of my clients who was struggling to drop weight (and feeling tired all the time) after he went vegan was surprised to learn he was only consuming about half the protein he needed. Most vegans I work with need at least 60 grams of protein per day. But many don't know if they're hitting that quota.
To make sure you're getting enough, try tracking your intake (even briefly) with an app like My Fitness Pal. Another strategy is to include more pulses (the umbrella term for beans, lentils, and peas) in your meals, since they are one of the best sources of plant protein. One cup of cooked lentils contains 17 grams of protein, compared to about 8 grams in a cup of cooked quinoa or a quarter cup of almonds. Whipping a plant-based powder (such as pea protein, made from yellow split peas) into a smoothie can also boost your intake, by as much as 25 grams per serving.

Whether you're a vegan or an omnivore, meal timing can have a serious impact your waistline. Many people I talk to eat their largest meal in the evening, when they're the least active. A smarter strategy is to eat larger meals earlier, so they fuel your most active hours of the day.
Skimping all day and gorging at night is a recipe for weight gain, or at least preventing weight loss-even if you're vegan. Try switching to evening meals that are filling but but light, such as sauted veggies and chickpeas over a bed of greens and spaghetti squash; or a broth-based veggie and white bean soup with a drizzle of EVOO.
I've had plenty of clients who believed it was okay to eat unlimited amounts of plant-based treats (think coconut milk ice cream and sweet potato chips). Plant-based frozen foods, desserts, and snacks can not only be high in calories, but they're often made with refined flour and added sugar, and stripped of nutrients and fiber. While they're fine as occasional treats, when consumed daily, they can pack on pounds. One study found that processed foods may decrease post-meal calorie burning by nearly 50% compared to whole foods. Trade processed plant foods for fresh snacks. Reach for in-season fruit and dark chocolate to satisfy a sweet craving; and raw veggies with hummus or guacamole for a savory fix.
There are many beverages marketed to plant-based consumers: kombucha, drinking vinegars, green juices, chia drinks, coconut water, and almond milk cold brew coffees, just to name a few. With so many choices, I've seen many clients unknowingly sip hundreds of extra calories per day.
My rule of thumb is this: If it's not water or unsweetened tea, your beverage should count as part of your meal or snack. One vegan client who found she wasn't losing weight was drinking a smoothie along with her lunch salad. Unknowingly, she was essentially consuming two lunches every day. Another client didn't realize that the healthy (and expensive) beverages she drank twice a day in lieu of soda contained about 300 calories total. That may not sound like a ton, but it would take a one-hour speed walk to burn off just those drinks.
Make good old H2O your drink of choice, and if you reach for anything else, take a careful look at the ingredients, nutrition facts, and serving size, so you can decide if it's the best fit for your body's needs.

Do You Have to Be Antisocial to Lose Weight? – Healthline


Picture your last meal at a restaurant with friends.
Plates loaded with delicious food.
People laughing and telling stories.
Wine glasses filled and refilled over the course of the meal.
A good time, right?
Sure. But researchers say theres a downside to all that social revelry, especially if you are trying to lose weight, or even just keep off the pounds.
New research has found that the urge to overeat is strongest when you are dining with others in social situations, especially when out at a restaurant.
The biggest source of temptation is when people are in restaurants and theyre with other people. In particular, being with others who are eating is a huge trigger, Lora Burke, PhD, MPH, the studys lead author, and a professor of nursing at the University of Pittsburgh, told Healthline.
But its not just your friends who can lead your diet astray.
People can feel food temptation even if theyre alone but are in sight of people who are eating, said Burke.

In the year-long study, researchers used a smartphone app to follow 150 people enrolled in a weight loss program.
The app asked people to check in up to five times a day, reporting whether they were tempted to stray from their eating plan, or if they actually did.
At the same time, they reported where they were, who they were with, and their mood.
Throughout the day they also reported whenever they ate or thought about eating foods or portion sizes that didnt fit their plan.
And they weighed themselves every day on a digital scale that sent data to the researchers automatically.
This use of technology in the study allowed researchers to capture information in real time, rather than relying on people to remember details later.
We assessed them in the moment, said Burke. Theyre in their natural environment wherever they are and they let us know what theyre doing, rather than relying on recall.
The amount of data provided some hints at how people react to food temptations in different situations.
People were more tempted when they were in the presence of other people eating, compared with eating alone even if they were sitting near strangers.
They also reported more food temptations when they were at a restaurant or bar, rather than at home or work.
And they were less likely to be tempted when eating in their car or at another persons house.
Not every meal with friends at a restaurant leads down the path of temptation.
But the study found out that when people were tempted at a restaurant and were around others who were eating, at least 60 percent of the time they will go on and eat something that they really werent planning for, Burke said.
The chance of giving in to temptation at work or in the car was about 40 percent and 30 percent, respectively.
The study was presented at a recent meeting of the American Heart Association.

So is locking yourself in your house with a bowl of salad and ignoring your friends text messages your best option?
Not quite.
Even though eating at a restaurant with friends can be a high-risk situation, friends can actually help you stick to your weight loss plan.
Other research found that people who received more social support were better able to keep the weight off. As were people who enrolled in a weight loss program with friends.
Plus, the new study found that even though people experienced fewer food temptations when they were at home, they still gave into them about half of the time. Even when they were alone.
So food temptation lies in wait in many places. As do distractions which some think may be behind our overeating.
People often overeat when theyre distracted social situations can be distracting, of course, Dan Zigmond, author of Buddhas Diet: The Ancient Art of Losing Weight Without Losing Your Mind, told Healthline. But sitting alone at your desk at work can be hugely distracting, as well. And theres lots of evidence that people make bad choices in that situation, too.
You can counteract the effect of these distractions by being more mindful while you eat.
This technique has been applied in successful weight loss programs. But its roots extend even further back.
Part of the theme of our book is to carry forward the teachings that Buddha presented so many years ago. Those really all boil down to just paying attention, said Zigmond. To try to ensure that youre always paying some attention to what youre eating, no matter where youre doing it, when youre doing it, or with whom.
Zigmond said that this works even in groups, as seen with Buddhist monks who eat their meals communally, and mindfully.
Mindful eating mind might mean something as simple as pausing for a moment before starting to eat. Or paying attention to each bite of food. Or talking about the food with your friends.
In the end, this can improve the dining experience for everyone, without leaving you feeling guilty afterward for overeating.
I dont think meals out with friends have to be bad for our health or our weight, said Zigmond. But we have to combine them with a certain amount of attention and mindfulness.

Diets Don’t Work, Body Love Does | The Huffington Post – Huffington Post


Weve all been taught the same diet myth since we were tweens. Diet, lose weight, get a perfect body, be happy. Go from your before photo to your after. Its a clean, linear journey that we buy into in the form of products, programs, and the zeitgeist of weight loss in our world today.
If I fail at this clean, linear transformation, we think, theres something wrong with me.
We get in our heads and internalize dieting failures. Im lazy, I lack discipline, I dont want it badly enough, Im (gasp) an emotional eater. Put down the cookie and get it together, honey! We tell ourselves terrible things when we dont achieve the transformation we are seeking from dieting.
Happiness is just six weeks away. If you could just stop being such a fat slob and stick to your diet plan--right?
The "diet myth" promises us a clean, one-time, linear journey to happiness: Diet, lose weight, get a perfect body, be happy. . But this clean, linear journey doesn't really exist. Many women don't succeed at losing weight through dieting. . Even if you do, @neda has found that 95% of dieters will regain their lost weight within 5 years. . The diet myth is just that--a myth. And you have better things to do with your precious time, money, and energy than spend it all buying into yet another diet plan, program, or "get thin quick" solution. . Dieting isn't the answer, Loves--choosing to love your body, exactly as it is, and taking the best possible care of that body right now, is. | @bryanwhitely hmu @laurenolearybeauty

The diet myth is just that--a myth. And you have better things to do with your precious time, money, and energy than spend it all buying into yet another diet plan, program, or "get thin quick" solution.
The reality is that most people dont lose very much weight from dieting. Those that do lose weight tend to gain it back, plus more. 95% of dieters regain their lost weight within 5 years, according to NEDA. Not only that, but multiple studies have shown that dieting is actually associated with greater weight gain, rather than weight loss.
The unicorns among us that do manage to lose 10, 20, 50, 100 or more pounds get to their weight loss goal and still find flaws with what they see. Plastic surgeons are now marketing solutions specifically to patients who are successful at losing weight through gastric bypass. The after photo, if you even manage to get there, is not all that its cracked up to be.
Were spending upwards of $60 Billion on diet and weight loss here in America. Based on the statistical truths about dieting, we would be better off throwing that money out the window while we cruise down the freeway.
Or funding Planned Parents annual operating budget 60 times over. Or giving 60 Million pets a forever home. Or building 7.5 Million wells to provide clean drinking water to the developing world. We could do a great deal more with those resources than simply chasing an unattainable standard of body perfection.
Reading this might make you feel deflated or hopeless--but it shouldnt! This is an incredibly liberating truth. You are free from feeling obligated to buy into another plan or program. You dont have to go through your days restricting your eating. You dont have to use up your brain power assessing your food choices against the latest diet craze. You dont have to use up your precious time, energy, and resources buying into the diet myth.
Whether you just inhaled a bag of Cheetos or ran a half marathon, you are free to love the body that you have right now. Even if you do want to lose weight, improve your health, or transform parts of your exterior, it starts with loving your body exactly as it is. Reinforce that love for your body every single day. Celebrate what your body is capable of doing.
When you approach your diet and exercise choices from a place of self-love, it all comes together, and youll be able to make the true transformation to a more healthy lifestyle.
So please, I beg of you. Dont go on another bikini body diet. Just love the body that you have, harder than ever before.

Commentary: How Government Intervention Changed American Diets – 89.3 WFPL


Theres a lot of buzz in Washington about reducing the size of the federal workforce. The release of the Trump administrations first budget gave us a better idea of the political agenda for those cuts, and many valid and popular government programs could be at risk.
Ive been reading a new book that tells a different story: A Square Meal: A Culinary History of the Great Depression focuses on the years following the crash of 1929, and how federal involvement in agriculture, welfare and nutrition shaped the nations health.
Authors Jane Ziegelman and Andrew Coe remind us that there was a time when the federal government had almost no role in the private lives of its citizens. Although there were cycles of boom and bust in the economy, individuals expected little or no help from Washington, and Washington had little or no interest in helping individuals.
The unexpected depression of food prices in the 1920s, which devastated the farm economy, seemed to have little impact on the folks who lived in cities, where urban prosperity cushioned professionals, office workers and most factory laborers from hardship. The Roaring Twenties left the farmer behind.
And the Depression only made it worse. President Hoovers platitudes about hard work were at odds with long breadlines, reports of malnutrition by social workers and school employees, and headlines about crops being left to rot in the fields because it was too expensive to harvest them.
The Red Cross became the chief distributor of welfare, mostly in the form of grains, milk and other staples, but their efforts were limited and inadequate. In New York, Gov. Franklin D. Roosevelt paved the way for more centralized efforts to feed and clothe the people. Led by his welfare chief Harry Hopkins, a social worker, the push for a national effort came with the 1932 presidential election. FDR took over the White House from the hapless Hoover, and Hopkins went to Washington to implement the National Recovery Act.
Private welfare, always a somewhat stingy and unreliable form of aid, was replaced by national support for the needy, and every conceivable program promoted hard work as a condition for receiving support. With unemployment rising to 25 percent or more, the alternative to welfare would have no doubt triggered revolutions like those that had swept the Communists to power in Russia and the Nazis in Germany.
With the aid came the power to recommend what people ate. Home economists were held in high esteem, putting many people to work who had training in the scientific study of food. Many believe that improvements in diet prepared American youth to fight and win World War II.
Eleanor Roosevelt became the nations advocate and role model, adapting the White Houses menus to put on the presidents platethe same simple, cheap and often bland food that his people were eating. Privately, FDR didnt think much of it. He came to detest the housekeeper, one Mrs. Nesbitt, who watered down his favorite stew and put meatloaf on the table rather than fresh game.
The shift in diet changed America in more ways than that. Malnutrition decreased. Prior to the 1930s, farmers and factory workers focused on intake of calories. Around the turn of the 20th century, most American adult males ate at least 4,000 calories a day to retain energy for their labors. Today, most adults should eat fewerthan 3,000. The popularityof fast food and the additives that expand its production have resulted in a national crisis of obesity.
How the wave of Trump-era cuts could affect our daily lives is still unclear. But A Square Meal reminds us of the value of some federal leadership in the field of public health.

DuPont cracks enzyme combo for boosting Indian layer production – FeedNavigator.com


DuPont says its new enzyme combination for inclusion in Indian layer diets has the ability to improve egg production by 2% and feed conversion ratio by 3%.
This week, DuPont Industrial Biosciences announced the launch of Axtra XBPHY, a new three-in-one enzyme product that promises to improve layer performance in hens whose diets are high in phytate and non-starch polysaccharides (NSPs).
The enzyme combination was developed specifically with the fast-growing Indian layer market in mind, but DuPont told FeedNavigator it could have application in other markets.
While it is still early, we are already experiencing great feedback from customers. Because of this initial encouragement, we will now look to other local markets to better understand diet composition nuances and the specific challenges customers face in achieving optimum layer performance. The outcome of that work will help us develop the best solution to meet customer needs in those markets, said Dr Ajay Awati, poultry segment manager atDupont Industrial Biosciences.
Indian layer diets usually consist of ingredients with lower digestibility caused by high levels of NSPs like bajra (millet), cotton seed meal, rice distillers dried grains with solubles, de-oiled rice bran, rapeseed and sunflower meal.
Internal ingredient profiling work conducted by DuPont found that this diet is high in the anti-nutrients phytate and NSPase.
The phytate in the diet not only makes valuable phosphorus unavailable but also has anti-nutritional effects that bind nutrients and make them unavailable for digestion. Similarly, NSPs, especially present in the cell wall structure of the feed ingredients, can hinder access to nutrients inside the cell and reduce digestibility of those nutrients, affecting the overall performance of the birds, explained Dr Awati.
Layer hen trials designed to examine the effectiveness of its enzymes to target specific anti-nutrients led DuPont to the development of Axtra XBPHY - a combination of phytase, xylanase and beta-glucanase.
Explaining how this trio of enzymes works to increase nutrient availability, Dr Awati said: By increasing the degradation of phytate with a fast acting phytase, you release much needed phosphorus, along with bound nutrients. Combining that with xylanase and beta-glucanases to degrade fibers and NSPs from the cell wall makes the nutrients that were trapped inside the cell wall accessible to the birds own enzymes. This increases the overall nutrient availability from low cost, high fiber diets and is reflected in the performance improvement of laying hens.
He said that DuPont had observed egg production and feed conversion ratio improvements of up to 2% and 3% in its own research, and had observed a significant increase in egg weights when adding the NSPase portion of the enzyme on top of a diet.
Depending on whether a customers objective is feed cost reduction or laying hen performance improvement, the enzyme can be applied either with nutrients and energy matrices or over the top of current diets, he said.
The enzyme combo is formulated in free-flowing granular form for adding directly or via a premix at a rate of 0.2kg/ton (0.02% of complete feed).
To date, the benefits of Axtra XBPHY have only been tested in internal trials, but DuPont confirmed that it is running trials with customers to demonstrate its effectiveness in commercial settings.
In addition, a number of DuPonts layer customers are testing the product within their facilities.
We are positive that the outcome will confirm the value provided by Axtra XBPHY to Indian layer customers, said Dr Awati.

Genome-based Diets Maximize Growth, Fertility, Lifespan – Laboratory Equipment


A moderate reduction in food intake, known as dietary restriction, protects against multiple aging-related diseases and extends life span, but can also suppress growth and fertility. A research group from the Max Planck Institute for Biology of Ageing in Cologne has now developed a diet based on the model organism's genome, which enhances growth and fecundity with no costs to lifespan.
What is the best path to a long and healthy life? Scientists had a relatively simple answer for many years: less food. But it turned out that this could have unpleasant consequences. Experiments showed that putting flies or mice on diet could impair their development and fecundity. How could we take advantage of the beneficial effects of dieting, and at the same time avoid the damaging effects?
Genome-based diet
Scientists at the Max Planck Institute for Biology of Ageing in Cologne and UCL Institute of Healthy Ageing in London have now designed a diet based on the model organism's genome. In the study they calculated the amount of amino acids a fruit fly would need, thereby defining the diet's amino acid composition.
"The fly genome is entirely known. For our studies we used only the sections in the genetic material that serve as templates for protein assembly - the exons, which collectively make up the 'exome.' Then we calculated the relative abundance of each amino acid in the exome, and designed a fly diet that reflects this amino acid composition," explains George Soultoukis, scientist in the department of Linda Partridge, director at the Max Planck Institute for Biology of Ageing in Cologne and at the UCL Institute of Healthy Ageing in London.
Using a holidic fly diet previously developed by the team to enable manipulation of individual nutrients such as amino acids, the group found that flies eating this exome-matched diet develop a lot faster, grow bigger in size, and lay more eggs compared to flies fed a standard diet. Remarkably, the flies on the exome-matched diet lived as long as slower-growing, fewer-egg-laying flies fed with "standard" diets.
"The flies that had free access to the exome-matched diet even ate less than controls. Thus, high quality protein, as defined by the genome, appears to have a higher satiety value," said Matthew Piper, who conducted the work at UCL and is now working at Monash University.
The study also found that similar phenomena may occur in mice, and future mouse work could further improve our understanding of how and why diets affect mammalian lifespan.
"Our aim now is to characterize the effects of genome-based diets upon mammalian lifespan," says Soultoukis.
Human diet
In theory this approach is applicable to all organisms with a sequenced genome including humans.
"Dietary interventions based on amino acids can be a powerful strategy for protecting human health. Obviously factors such as age, gender, health, and personal lifestyle also have to be taken into account. Future studies may still employ novel -omics data to design diets whose amino acid supply matches the needs of an organism with even higher precision. Understanding why we need amino acids in the amounts we do will be key, and such studies provide novel and powerful insights into the vital interactions between nature and nurture," explains Soultoukis.

The key to successfully maintain weight loss – Knowridge Science Report


Recently researchers have published the studies to follow weight loss maintenance for individuals over a 10-year period.
The results show that long-term weight loss maintenance is possible if individuals adhere to key health behaviors.
For example, one is a 10-year observational study of self-reported weight loss and behavior change in nearly 3,000 participants.
The participants had lost at least 30 pounds and had kept if off for at least one year when they were enrolled in the National Weight Control Registry (NWCR).
The participants were then followed for 10 years.
Researchers said, On average, participants maintained the majority of their weight loss over this extended follow-up period, and better success was related to continued performance of physical activity, self-weighing, low-fat diets, and avoiding overeating.
Other findings show that more than 87 percent of the participants were estimated to be still maintaining at least a 10 percent weight loss at years five and 10.
A larger initial weight loss and longer duration of maintenance were associated with better long-term outcomes.
Conversely, decreases in physical activity, dietary restraint and self-weighing along with increases in fat intake were associated with greater weight regain.
Researchers conclude, This is one of the only studies to follow weight loss maintenance over such a long term.
What the results tell us is that long-term weight loss maintenance is possible, but it requires persistent adherence to a few key health behaviors.

Gut bacteria plays a role in long-term weight gain – The Conversation – The Conversation UK


Weight gain happens when we consume more food than we can burn, and weight loss happens when we burn more energy than we consume. But why do some people seem to eat whatever they want and not gain weight, and others appear to gain weight even if they eat reasonable amounts of food? The answer, at least in part, may be found in the bacteria that live in our guts.
Our latest research, published in the International Journal of Obesity, shows that people who have a stable weight over nine years or lose weight, have a larger number of different types of microbes in their guts, eat more fibre and have a higher abundance of certain types of gut microbes.
In the past decade, researchers have found that the microbes in our gut have a strong effect on various aspects of our health. Studies in mice have demonstrated that how the body converts food into energy depends in large part on the different types of microbes a person has in their gut and also on the kind of microbes they carry.
In a recent study, scientists in Israel found that mice who were put on a yo-yo diet slowly gained weight compared with mice on a steady diet despite the fact that both groups received the same amount of calories overall.
One of the effects seen in the mice that were put on the yo-yo diet was a decrease in their gut microbiome diversity. Also, when they transplanted the microbes from the yo-yo dieters into the guts of non-yo-yo dieters, the mice on steady diets gained weight showing that the altered microbes were the cause of the weight gain. But is this relevant to humans?
In humans, comparing microbes in the gut in obese and thin individuals, scientists have already shown that lean people have many more species of intestinal bacteria than obese people.
Until now, however, there were no experiments tying the gut microbes to changes in weight over several years. For this reason, we decided to do an investigation into 1,632 women from the UK, all of them twins (about half of them identical). The participants had their body weight measured several years ago and, back then, they answered questions about the amounts and types of foods that they ate. We called them again nine years later and, in addition to measuring their weight, we asked them to give us a poo sample so we could analyse the bacteria in their gut.
We found that most of the women gained weight over the nine years, but this was not fully explained by the number of calories in their diet when the study began. Because they are twins, it was also possible to calculate (using the differences between identical and non-identical twins) how much of the weight gain can be explained by genes. Only 41% of the change in weight was explained by genes. That meant that there were other factors, in addition to genes and calories.
We discovered that women who ate high amounts of dietary fibre (found in fruit, vegetables and whole grains) were less likely to gain weight than those who ate little fibre, even if they consumed roughly the same amount of calories. Women who lost weight or had stable weight also had more diverse microbes in their guts. We were able to pinpoint some of the microbes that are different between women who had gained weight and those who had lost weight. Most of these microbes had already been discovered in mice to be involved in better energy metabolism.
These results show that the exciting studies in mice about how microbes affect weight gain are also relevant in humans. They are also important because they will allow our group, and other scientists, to investigate how to influence a persons gut microbes using probiotics and fibre so they are at a lower risk of developing obesity.
