Despite the increasing number of people in the United States who say that they are trying to lose weight, the average body mass index (BMI) of U.S. adults is on the rise.

This is according to new research appearing in the journal JAMA Network Open.

Dr. Lu Qi, director of the Tulane University Obesity Research Center in New Orleans, LA, is one of the corresponding authors of the study.

As per the study paper's title, the research examined "[t]rends in self-perceived weight status, weight loss attempts, and weight loss strategies among adults in the United States" in 19992006.

Dr. Qi and team used nationally representative data from nine applications of the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2016.

In total, they had access to data from 48,026 participants. The researchers examined trends in measured BMI and weight, self-reported weight during the past year, and the difference between measured weight at present and self-reported weight in the prior year.

The study demonstrated that the proportion of participants who tried to lose weight increased over the study period, despite the fact that current weight and weight in prior years had increased.

Specifically, the number of adults who said that they had tried to lose weight rose from 34% to 42% in 19992016. During this time, the most common weight loss strategies the participants applied were eating less, exercising more, and drinking more water.

U.S. adults also reported changing their eating habits, such as "consuming less sugar, candy, and sweets" and eating less junk food or fast food.

However, despite these efforts, the "trends for actually measured weight and self-reported weight history increased during the same time period," the study authors write.

In fact, if 33.7% adults had obesity in 20072008, this number jumped to 39.6% in 20152016.

This suggests, the study authors explain, that the weight loss strategies "may not have translated into effective weight loss," even though studies show that these strategies should be effective.

"These findings," says Dr. Qi, "suggest that although 3442% of U.S. adults in our study reported weight loss efforts, many of them might either not actually implement weight loss strategies or apply a minimal level of effort, which yielded unsatisfactory results."

In other words, U.S. adults hoping to lose weight would need to apply more effort, particularly in terms of adherence. "Reduced food consumption is one common strategy to lose weight, but modified diets are difficult to maintain," says Dr. Qi.

"These findings suggest a need to increase the promotion of effective strategies for weight loss, including caloric reduction and increased physical activity, among all adults attempting to lose weight," she adds.

"Notably, adherence is the primary factor predictive of a successful response to a weight loss attempt. Therefore, weight loss strategies that consider a participant's preferences and abilities may help them stick with it long-term."

Dr. Lu Qi

The researchers also mention the possibility that the contradiction in trends is down to the fact that the participants who tried to lose weight were not those who may have needed to.

Conversely, those who might have needed to lose weight for health reasons may not have tried very hard to do so because they considered their weight to be "normal."

In fact, the number of people who thought they were "approximately the right weight" also increased over the 15 year period, report the researchers.

The researchers acknowledge some other potential limitations to their study. Firstly, participants self-reported the data on weight self-perceptions and weight loss efforts, which makes the information subject to potential bias.

However, the study authors say that the difference between how the participants reported their current weight and their measured weight was minimal, indicating that their approximations may have been correct.

Secondly, the NHANES surveys did not collect information on the "frequency, duration, or number of weight loss attempts or strategies."

Finally, and importantly, the study could not establish causality or temporal relationships in the observed trends.

Average US BMI on the rise despite increasing weight loss efforts - Medical News Today

As an aesthetic society, we often demonise body fat and stigmatise people with lots of it. Theres often an assumption that people carrying excess weight dont exercise and must be unhealthy.

But thats not true: you can be fat and fit. In fact, as we age, low levels of fitness can be more harmful to our health than high amounts of fat.

For those considering starting exercise, try looking beyond weight loss for motivation. No matter how much you weigh, there are always benefits to exercise.

Exercise actually does a pretty poor job of getting us to expend enough excess energy to lose weight. This is partly due to a compensatory effect of our appetite, which increases after we exercise.

Exercise changes our body composition how much fat we have as a ratio to how much lean (muscle) tissue we have but this doesnt always cause big changes on the scales.

Here are just five ways exercise improves our health, no matter how much we weigh.

Cardiorespiratory fitness is a measure of how far and hard you can run without needing to stop, or how many stairs you can climb without being out of breath. Running for longer, or climbing more stairs, means you have a higher absolute cardiorespiratory fitness which cannot be improved with weight loss alone.

Having a high body mass index (BMI) may reduce the absolute intensity you can exercise but it doesnt mean it is less effective.

You may be able to jog between every third lamppost, for example, but not run consistently for 1 km. While it may seem the periodic jogging is not as impressive, its all relative to your baseline and any exercise is better than none.

If youre carrying a lot of excess weight, you might prefer non-weight bearing exercise such as swimming or cycling indoors to minimise stress on your joints but this will depend on you and what you like doing. After all, youre more likely to continue exercising if you enjoy it.

If youre thinking but I hate running/swimming/cycling/dancing and Id rather lift weights, then lift weights! Although lifting weights doesnt have the same effects as cardio training, the benefits are still as important for mobility, joint function and maintaining muscle mass as we age.

Exercise reduces the risk of heart disease and stroke, even in those with a chronic disease such as diabetes, irrespective of body fatness.

Regular exercise helps lower blood pressure, improves delivery of blood throughout the body, and reduces inflammation, even in those with a high body mass index.

Exercise improves our bodys ability to use energy. We store large amounts of energy as fat, which is quite hard to break down, as it costs a lot of oxygen compared to cheaper fuels for the body to use like glucose.

But when we exercise regularly, we increase our bodys ability to use fat as a fuel source as well as requiring more energy at rest.

This doesnt necessarily mean more exercise equals more fat loss, but it does mean more fat turnover, and typically less fat stored in and around the organs (the bad visceral fat).

Research has consistently shown that people who exercise (regardless of body size and shape) have better mental health and lower levels of stress, depression and emotional problems.

It does this via blood flow to the brain, increased release of endorphins that make us feel happy, and by helping to moderate the brains response to stress.

Often, the hardest part is getting started with exercise or going to perform the exercise, but once you are moving the mental health benefits begin.

While exercise may not help us lose a lot of weight on the scales, its a good way to keep weight off and prevent weight regain.

Regular exercise continues to encourage the body to use stored fuels and remodel tissues (such as muscle) to grow healthier and stronger.

But preventing weight regain is tough. People who have lost weight may need greater amounts of exercise to counteract the physiological drive to return to the heavier body weight.

The popular weight-loss trend ofintermittent fastingisnt going anywhere and has only continued to gain steam, with celebrities likeKourtney Kardashian,Hugh JackmanandChris Prattextolling its virtues. The latest stars to jump on the fasting bandwagon areJenna Bush Hager and Hoda Kotb, who decided to try intermittent fasting together (and publicly weighed themselves on camera on Today with Hoda and Jenna).

So what, exactly, is intermittent fasting? Intermittent fasting is a weight loss or weight control strategy where youre cycling between periods of eating and fasting,Sarah Adler, PhD, a psychologist with the Stanford Eating Disorder and Weight Control Clinic, tells Yahoo Lifestyle.

There are several ways to do intermittent fasting, but it typically involves choosing a specific window of time in which you can consume food or caloric drinks. It can be as simple as skipping breakfast and eating at noon or finishing your last meal earlier, says Adler.

One popular method is 16:8, where people fast for 16 hours and only eat during an 8-hour window, such as noon to 8 p.m. While fasting for 16 hours does sound like a lot, keep in mind that includes (hopefully) 8 hours ofsleep. Theres also the 5:2 method whichJimmy Kimmelfollows where people eat restricted calories (such as 500-600 calories per day) for two nonconsecutive days and then eat normally for the other five days.

For many who are able to stick with it, intermittent fasting is the magic bullet forweight loss. Ive seen a lot of people who have struggled with weight loss and have done intermittent fasting, and it seems to be the magic bullet for them,Liz Weinandy, a registered dietitian at The Ohio State University Wexner Medical Center, tells Yahoo Lifestyle. Its because people are not eating as much.

Theyre also eliminating late-night eating, which can include less-than-healthy options like chips and ice cream. Once they stop eating after dinner, that alone helps a lot of people start to lose weight, says Weinandy. For a lot of people, theyre not eating those extra 300 or 400 calories.

Intermittent fasting can also have a diuretic effect when the body gets rid of excess water which leads to some fluid weight loss as well, according to Weinandy.

However, its worth noting that some researchers say theres not enough scientific evidence on the long-term weight loss effects of intermittent fasting. The research based on the efficacy of intermittent fasting is fairly limited in humans, so most is anecdotal, says Adler. In addition, a 2018 Germanstudy described as the largest investigation on intermittent fasting to date involving 150 overweight and obese people on either intermittent fasting or conventional calorie-restricting diets, who were examined over the course of a year, found that intermittent fasting wasnt any more effective at weight loss than calorie restriction.

That said, intermittent fast has other health benefits. Insulin levels go down, says Weinandy, because if youre not taking in any food, especially carbohydrates, our blood sugar isnt going up.

Adler explains that when you eat carbs, for example, the body breaks it down and converts it into sugar (glucose). But if you eat more than your body can use for energy, the sugar gets stored in fat cells."Insulin brings sugar into fat cells and keeps it there," says Adler. "Between meals, our insulin levels go down and our fat cells release the stored sugar to use as energy. Intermittent fasting allows for insulin levels to drop so that [stored sugar] gets burned off."

There are other positive metabolic effects, including an increase inhuman growth hormone. Its important for muscle maintenance, especially as we get older, says Weinandy. Intermittent fasting also appears to help on a cellular level torepair DNA, says Weinandy, by triggering autophagy the bodys way of cleaning out damaged cells to then generate new, healthy ones.

However, not all types of intermittent fasting are created equal. Research around intermittent fasting that shows health benefits are really limited to a very specific kind of intermittent fasting basically, the 16:8 method, points out Adler. The health benefits have not been shown to be associated with other forms of intermittent fasting, like the 5:2 method.

Most side effects are fairly minimal, notes Adler. When people first start intermittent fasting, some may experience mild headaches or lightheadedness. In some cases, people who are not following the 16:8 method may find themselves overeating at other meals. With intermittent fasting, 16:8 has been shown to reduce overeating in other meals, says Adler. Outside of that is when youre getting overeating, increased hunger, and loss of energy.

The eating method also isnt right for everyone, says Weinandy. For example, some may find that skipping breakfast in the morning isnt sustainable. In that case, not snacking after dinner, such as cutting off food by 8pm (or earlier in the evening), may work better for them. Dont go hot and heavy into it, suggests Weinandy. Gradually stop eating after dinner.

Adds Adler: "People need to use an approach that works for them and is sustainable for them.

In general, its considered pretty safe for the majority of people, says Weinandy. But women who arepregnantor are trying to get pregnant, as well as women who arebreastfeeding, should not attempt to do intermittent fasting. Also, Anyone who has a history of eating disorders should not be intermittent fasting, notes Adler. People with heart conditions and diabetes who are interested in trying the method should be monitored by a physician, who is knowledgeable about metabolic conditions.

What you need to know about intermittent fasting and who should avoid it - Yahoo Lifestyle

For the study, participants were split into a group of two. While one group received a low-calorie diet (particularly low on carbs), the other group was allowed to have the same breakfast, but with some additional carbs by allowing them to have something sweet-like chocolate, doughnuts or a slice of cake. Both the breakfasts were also rich in protein as well. The study was conducted over a period of eight months.

After the time period finished, participants in both groups were able to lose weight. However, in the last four months of the study, it was seen that people in the first group who weren't allowed a dessert regained some kilos and weren't able to sustain weight loss, as compared to the 'dessert' group-who were able to reduce their cravings in the long run and reported feeling satiated and less hungry too.

According to doctors, the prime idea behind losing weight is to not just lose the fat and the extra weight but also modify the appetite by reducing cravings in the long run which could prevent piling on the lost kilos.

Weight loss: The perfect time to eat a dessert - Times of India

Oprah Winfrey is one of the worlds most famous yo-yo dieters. She lost 67 pounds in 1988; by late 1990 she had regained most of that weight. In 1994 she was thin again and she completed the Marine Corps Marathon. But by 2008 when she hit 200-plus pounds, she wrote in O Magazine that she felt really uncomfortable! Since then shes lost 42 pounds and hopes to never have to try to lose weight again.

Down and up. Down and up. Its a hard pattern to break, and one that millions of Americans experience annually. According to the Centers for Disease Control and Prevention, from 2013 to 2016 around 56% of women and 42% of men tried to lose weight. But research shows that in the first year after dieting, most folks regain 33% to 66% of the weight they lost, and almost all the weight is regained within five years. Thats hard on your spirit, your clothes budget and your body!

Some studies have shown that yo-yo dieting increases your risk for heart disease and stroke, leads to added weight gain and raises your risk for a variety of health problems related to chronic inflammation. It can also lead to long-term loss of muscle mass if you dont eat enough lean protein to fight it off. That makes you weaker and lowers your metabolism, making it easier to regain weight.

WHY MAINTAINING WEIGHT LOSS IS SO HARD

Extreme action (super food deprivation, precipitous weight loss, over-exercising) leads to an equal and opposite reaction (indulgence in comfort foods, sedentary behavior and a physiological reaction where the body thinks, Yikes! Im starving; feed me more!). That causes weight rebound.

4 WAYS TO MAINTAIN WEIGHT LOSS

1. Learn a stress management technique and practice it daily. People who manage stress successfully lose weight without even trying. Meditation is useful for easing stress and focusing your determination.

2. Lose weight slowly (a half- to one pound a week) by changing your eating habits and increasing your activity level. That lets your body your behavior patterns and metabolism adjust so that youre less likely to regain lost weight.

3. Change your relationship to food. Theres no ironclad diet that is the key to losing and keeping off excess weight. Moderation within some easy-to-follow guidelines does the trick.

>> Go for a plant-centered diet; eat lean animal protein and fish; enjoy healthy oils from nuts, olive oil; and choose fiber-rich foods like 100% whole grains and produce. But stay flexible. Enjoy your options.

>> Identify when you use food for emotional comfort. As you reach for that box of cookies, ask yourself, Am I bored? Anxious? Sad? Then make sure to have snack alternatives like nuts and pre-cut veggies around. Also try activities to ease those emotions: Take a walk, call a friend or write in a diary.

>> Learn to cook new dishes. Spend time reading through recipes online. Pick one a week thats tasty and healthy. Make shopping a fun excursion. Get your kids and partner involved. Have a friend over to try your creation.

>> Do not eat after 6:30 p.m., eat your biggest meal at midday and have breakfast at least 13 hours after dinner.

4. Move more; build muscle mass.

>> Its never too late to gain benefits from physical activity, so start with whatever makes you comfortable and build endurance slowly. Every week, try to increase your efforts by 10%. Do you walk for 20 minutes a day? Then go for 22 minutes. Your ultimate goal is 300 minutes of physical activity a week. With 22 minutes x 7 days a week = 154 thats more than halfway there!

>> Diversify your activities. Combine walking and aerobics with bouts of intense effort, strength building, agility and balance skills (yoga, jumping, Pilates). There are enough choices to find something that is enjoyable every day.

Once you have lost weight, adopt these guidelines and youre on your way to a lifetime of better health and happiness.

How to prevent the weight you've lost from returning - Honolulu Star-Advertiser

Comments made by EFSAs Panel on Nutrition, Novel Foods and Food Allergens (NDA) refer to the consumption of GlycoLite, an aqueous extract from white kidney bean (P. vulgaris L.) that is the subject of a health claim application by analyze & realize GmbH.

The applicants object to the conclusions reached by the Panel on two human intervention studies performed in the same centres as well as the absence of a plausible mechanism of action.

analyze & realize, a contract research organisation (CRO) serving the food sector, also highlight inconsistencies in assessing the application versus a successful claim made on the dietary fibre glucomannan.

In both claims, the claimed effect was a reduction of body weight, the technical report comments.

In relation to the glucomannan claim the applicant states, the sole study that ran over a sufficiently long period appears to have obvious shortfalls in the statistical reporting and in the study population (the study was conducted on severely obese women).

Additionally, the dose tested was higher than in the proposed conditions of use for the claim (a dose of four grams per day (g/day) was used in the study, whereas at least three grams of glucomannan daily was indicated in the conditions of use for the claim by the NDA Panel).

In response, EFSA quotes guidance that states evidence for a sustained effect with continuous consumption of the food/constituent over, for example, about 12 weeks, should also be provided.

This doesnt mean that all the studies submitted for the scientific substantiation of the claim to be considered as pertinent by the NDA Panel should last 12 weeks, EFSA says.

This means that, whenever the claim is substantiated through intervention studies of shorter duration, evidence for a sustained effect with continuous consumption of the food/constituent over approximately that period of time should also be provided (i.e., at least one study).

Further issues centre on GlycoLites negative opinion, which is claimed required a mechanism of action in order to substantiate the claimed effect.

This, according to the applicant, is not in line with EFSAs guidance documents on health claim applications.

EFSA hit back stating that evidence on a mechanism of action is not a strict requirement for claims substantiation.

However, when present, is one of the elements considered by the NDA Panel in weighing the evidence because it increases the confidence on the biological plausibility of the effect, the report outlines.

The comments received did not provide evidence which would warrant a change in the conclusions of the NDA Panel.

The report, published in the Authoritys officialjournal, also responds to analyze & realizes claim that one study was disqualified by EFSA because it had been conducted in the same centre and by the same research group as another submitted study.

The organisation points out this is not consistent with EFSAs Guidance documents because the opinion adds a new requirement for studies to be considered as evidence for a claim (different centres and/or research groups).

In the Scientific Opinion on GlycoLite and reduction of body weight, the NDA Panel, in weighing the evidence, notes the results of the two human studies conducted under energy restriction had not been independently replicated AND that there was no evidence for a plausible mechanism of action.

In the absence of evidence on dose-response, the confidence of the NDA Panel on a consistent effect of GlycoLite on the reduction of body weight was not enough to consider the claim substantiated, even if none of these are absolute requirements for substantiation.

In a twist of fate, a 35-year-old New York woman said that being diagnosed with stage 4 oral cancer and losing 95 percent of her tongue actually saved her life at a time when she was topping the scales at nearly 650 pounds.

I had to die a little in order to learn to appreciate how it felt to truly be alive, Jen Costa, who has dropped nearly 500 pounds in two and half years, told SWNS. Im alive for the very first time in my life.

MAN OVERCOMES DECADE-LONG HEROIN ADDICTION, REACHES MILLIONS WITH VIRAL BLOG POSTS

Costa said it started in 2015 with pain in her mouth while ordering food on the phone, and that she sought the opinion of a dentist who allegedly dismissed the small white lump on her tongue as a virus. When she finally found a doctor willing to take her complaints seriously, she learned that it was stage 4 squamous cell carcinoma that had spread to the lymph nodes in her neck, SWNS reported.

Costa, pictured before her weight loss, had grown addicted to food following a car accident that left her bedbound at age 19. (SWNS)

Despite her diagnosis, doctors were unwilling to treat her because of her obesity.

"He told me he didn't feel comfortable operating on me because of my size, Costa told SWNS. "He denied me surgery because he said the radiation wouldn't get through to my neck because of all the fat.

COMEDIAN WITH CEREBRAL PALSY SHARES HOW SHE FINALLY GOT HOLLYWOOD TO NOTICE HER

Costa said her weight trouble began after a car accident left her bedbound. She said she spent her days eating takeout food and had started self-medicating with drugs, eventually gaining 350 pounds over 14 years.

She had to have 95 percent of her tongue removed and reconstructed using pieces of her skin in order to fight the aggressive cancer. (SWNS)

She did eventually find a doctor willing to operate, but it involved removing 95 percent of her tongue and reconstructing it using skin from her arm. Costawas told she risked needed a feeding tube for the rest of her life, and would need a ventilator to breathe, but she has defied the odds, according to SWNS.

To be honest I dont know how I survived it, she told the news outlet.

Jen Costa has since dropped nearly 500 pounds and has undergone several skin removal surgeries after being placed on a liquid-only diet. (SWNS)

Costa now is on a diet of liquid shakes and has had several procedures to remove excess skin since her dramatic weight loss. She said she is unable to taste food and chew properlyand misses pizzaand the taste of her grandmothers chicken. Still, Costaknows she would have eaten herself to death if she hadnt been diagnosed with cancer.
