As obesity rates across the world continue to rise, understanding exactly why we put on weight has never been more important. That’s why the findings of a new study, which looked at whether there is an association between when we eat and how much weight we gain, could be very significant. Presenting their findings at the ENDO 2019 conference, which took place in New Orleans, the scientists from the University of Colorado in Denver said there is a link between eating later in the day and having a higher BMI, as well as more body fat. For the study, 31 adults who were either overweight or obese and had an average age of 36 years were closely monitored to assess their sleep, levels of activity, and diet. Interestingly, the study also showed that the participants who ate later in the day still had an average of 7 hours sleep each night, suggesting that lack of sleep may not promote obesity after all. Speaking about the findings of the study, Dr. Adnin Zaman, lead author, said “These findings support our overall study, which will look at whether restricting the eating window to earlier on in the day will lower obesity risk.”
Christmas Day is less than two weeks away and that means many of us will soon be gorging ourselves on all sorts of culinary delights. It’s a reality that will see a lot of people piling on the pounds this month ahead of the inevitable January fitness drive. But what if there was a simple way to limit the impact of Christmas feasting on our waistlines? A new study by the Universities of Birmingham and Loughborough in the UK suggests there is. According to the study involving 272 volunteers, regular home weigh-ins coupled with simple weight-loss tips can prevent people from putting on weight over the festive period. For the study, the volunteers were divided into two groups. One group weighed themselves regularly and were given dietary advice, including information on how many calories they needed to burn to negate Christmas food. The other group didn’t weight themselves and were only given a small amount of healthy lifestyle advice. The group that weighed themselves and had access to the additional information weighed 0.49kg less than the "comparison" group come the end of the study. Study lead author, Frances Mason, of the University of Birmingham's Institute of Applied Health Research, said “People gain a kilo of weight on average annually. Often this weight gain happens at Christmas, and is never fully lost. This could possibly be a factor driving the obesity epidemic.” In other words, by simply keeping track of your weight and understanding the impact the foods you are eating are having on your waistline, you stand a better chance of avoiding weight gain at a time of year that’s traditionally associated with piling on the pounds.

Despite the fact the number of people who are overweight or obese has risen over the past 30 years, fewer people are actually attempting to shed weight, according to a new study, the findings of which were published in JAMA. Around two thirds of the adult population in the United States are obese or overweight, putting them at increased risk of heart disease, stroke, diabetes, and other chronic diseases. However, new research has found that even though there has been a significant rise in the number of people who are overweight or obese since the 1980s, the percentage of U.S. adults who are trying to lose weight has fallen. For their research, study co-author Dr. Jian Zhang and her colleagues from the Georgia Southern University, analysed the data of 27,350 U.S. adults aged between 20 and 59 years. The analyses revealed that the rates of overweight and obesity increased by 13%, from 53% in 1988-1994 to 66% in 2009-2014. Furthermore, the researchers also found that the percentage of people who attempted to lose weight over the same period actually dropped by 7%, from 56% in 1988-1994 to 49% in 2009-2014. At present, people are deemed to be overweight or obese depending on their body mass index (BMI). A BMI of 25 to under 30 is considered overweight, while a BMI of 30 or above is considered obese. A healthy diet and regular physical activity are proven to help curb weight gain, which is why we should all make a conscientious effort to watch what we eat and exercise more.

The New Year is here and for many of you that will mean a new exercise regime designed to get you into shape and improve your overall health. For some people, though, sticking to a disciplined program of physical exercise is one of the hardest resolutions they can make because a lack of motivation gets in the way. But now new research sheds some light on why many people, despite understanding the benefits of regular exercise, find it hard in practice to stay physically active. Researchers from the Diabetes, Endocrinology, and Obesity Branch at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), led by Alexxai V. Kravitz, focused on why obese animals also have a hard time carrying out physical activity. They found that a dysfunction in obese rodents' dopamine systems might help explain why. Mice fed on a high-fat diet started gaining significantly more weight than mice fed on a normal diet. They were also observed to have fewer movements; spend less time moving; and were slower when they did move, compared with the lean mice. Most interesting of all was that the overweight mice's changes in movements did not correlate with body weight gain. Instead, the researchers found that a deficit in striatal D2R explained the obese mice's lack of activity. "In many cases, willpower is invoked as a way to modify behavior. But if we don't understand the underlying physical basis for that behavior, it is difficult to say that willpower alone can solve it," said Kravitz.
A Canadian study has questioned how a pregnant mother's consumption of beverages containing sweeteners might affect the weight of their unborn child. According to the authors, the risk of a mother's unborn child being overweight could be increased among those mothers who consume sweeteners on a daily basis. Dr. Meghan Azad, of the University of Manitoba, Winnipeg, Canada), and her staff questioned more than 3,000 women to learn about their eating habits during pregnancy. In addition, the body mass index (BMI) of their children was also measured at the age of one. The researchers made two main findings: 1. 5.1% of the young children at the age of one were already overweight. 2. Mothers who consumed one or more artificially sweetened drinks each day during their pregnancies doubled the risk of their unborn children being overweight by the time they were one. In conclusion, the researchers admit that their work includes some limitations such as the mothers reporting their eating habits via questionnaire. They point out, however, that "to their knowledge, this is the first study to investigate the potential effect of consuming artificial sweeteners during pregnancy and infant weight gain." In January 2015, the National Agency for Food Safety (ANSES) was less convinced. According to them, "the available data do not make it possible to identify any benefit or conclude on the risk associated with the consumption of intense sweeteners during pregnancy, whether it is maternal health, obstetric parameters, or health of the newborn."
New research suggests that the impact of dietary fats on our overall health is likely to be affected by the changes they cause in the stomach’s bacteria ecosystem. The findings, which were obtained by studies in mice, show that diets rich in omega-3 fats, such as fish oil, affect the gut’s balance of bacteria differently to diets rich in lard. Senior researcher Professor Fredrik Bäckhed, from the University of Gothenburg’s faculty of Health Sciences, also known as the Sahlgrenska Academy, led the team of European researchers who discovered that changes in gut microbiota are responsible for some of their health benefits. “We wanted to determine whether gut microbes directly contribute to the metabolic differences associated with diets rich in healthy and unhealthy fats,” said first study author Robert Caesar from the University of Gothenburg. And, even though the study was done in mice, he said: “our goal is to identify interventions for optimising metabolic health in humans.” Writing in the journal Cell Metabolism, Bäckhed’s team said they obtained their results by feeding either lard or fish oil to a group of mice for a period of 11 weeks. They then monitored the metabolic health of the study mice and found that dietary fat is a major community structure driver, which in turn affects the composition and diversity of gut microbiota. “We were surprised that the lard and the fish oil diet, despite having the same energy content and the same amount of dietary fibre—which is the primary energy source for the gut bacteria—resulted in fundamentally different gut microbiota communities and that the microbiota per se had such large effects on health,” said Bäckhed. Increased lard consumption promoted the growth of Bilophila, bacteria often linked to gut inflammation. In contrast, the fish oil diet increased the growth of Akkermansia muciniphila, bacteria known to reduce weight gain and improve glucose metabolism in mice. The bottom line is that eating a diet rich in fish oils is, as the study suggests, going to help you lose weight, compared to a diet rich in lard.
Every week, there seems to emerge new advice on dieting which contradicts previously accepted methods. This week is no different and it’s the turn of the protein-packed diet to get a meaty dressing down. An international team of researchers voiced their concerns about diets high in protein at the European Congress on Obesity in Prague. The research team looked at data collected from over 7,000 men and women over the age of 55 who had no previous history of heart disease. When quizzed about their eating habits, the individuals divulged their dietary trends over the last five years. The results showed that when carbohydrates were replaced with protein, the risk of gaining 10% more body fat was increased by 90%. Furthermore, higher protein intake was also linked to a 59% greater risk of death from any cause. When fat was replaced by protein, the risk of death rose even further to 66% said the researchers. "These results do not support the generalised use of high-protein diets as a good strategy for losing weight," said the study’s lead researcher Monica Bullo, of Pere Virgili Health Research Institute in Reus. She added: "Long-term efficacy and safety of these diets deserve more attention.” With 69% of the population of America overweight, high-protein diets have been favoured because they often provide quick results. However, the Centers for Disease Control and Prevention say that American adults are already eating enough protein and the American Heart Association website says it “doesn’t recommend high-protein diets for weight loss.” Photo credits: Guardianlv, Fawesome.ifood
It won’t come as any surprise that Americans gain weight as they get older. However, you may raise an eyebrow to learn that as Americans age and pile on the pounds, the quality of their diet actually gets better. Therefore, we can safely say that as their waists expand and they realise something needs to be done, Americans try and counteract their weight gain by eating salads and lean proteins. But, according to a new study by the University of South Carolina, improving one’s diet simply isn’t enough to stave off weight gain in our later years. Using data collected from 4,999 Americans aged between 20 and 70, the study painted a complete picture of how the individual’s diet and exercise levels alter over the years. Lead researcher Russell Pate Ph.D. said: "Our study points to the very important impact of physical activity on weight status in U.S. adults, and in particular it points to the critical role of the age-related decline in physical activity on the increasing rates of overweight and obesity that we see with aging.” The bottom line? Americans should absolutely be trying to achieve the 150-minutes of moderate exercise as per the federal physical activity guideline. According to the American Heart Association, the activity levels of Americans are generally lower nowadays because of more sedentary jobs, better mass transport options and technology. Being overweight increases the risk of diabetes, cardiovascular disease, reproductive problems and some cancers.
The thyroid gland is shaped like a butterfly and found at the base of your neck. It regulates every aspect of your metabolism by producing hormones. This includes everything from how fast you burn calories to how quickly your heart beats. Think of your thyroid as your body’s general thermostat. However, your thyroid can sometimes over-perform or under-perform and that can cause a number of issues to occur. When your thyroid over-performs it causes your pulse to race, your bowel movements to be accelerated, sudden weight loss, as well as excited and aggressive mood swings. When it under-performs it can cause your pulse to slow down, weight gain, constipation and depression. A thyroidectomy is the usual medical procedure undergone to treat disorders relating to your thyroid. These range from minor diseases to cancers and how much of the thyroid is removed totally depends on the reason for the thyroidectomy. If a partial thyroidectomy is performed then only part of the thyroid gland is removed and it may still be able to function normally post-surgery. If a total thyroidectomy is performed and the entire gland is removed, patients inevitably need daily treatment with thyroid hormone replacement therapy to counteract the removal of the thyroid gland. Find out more about thyroidectomies on our website and/or contact us today for more information on how we can facilitate a range of medical procedures for you right here in France.
Gastric surgery is used to treat people who are dangerously obese. The procedures available to aid weight loss in obese people are only used as a last resort and should not be considered to be an ‘easy option’ to weight loss. Gastric surgery is increasing in popularity with more people becoming unable to control their weight gain with routine exercise and healthy eating. There are 2 procedures which are most commonly performed in France: Gastric band This procedure uses surgery to place a band directly onto the stomach to reduce the size and in turn the amount of food that can fit inside the stomach. This makes the patient feel full and stop eating sooner. Gastric bypass This is a more complex procedure which involves re-routing the digestive system so that the majority of the stomach is bypassed. Again a patient feels full quicker and so eats less. Both procedures are very effective in reducing weight in France but should not be used in isolation. The medical team will want to ensure that the patient is willing to make the necessary changes to keep the weight off, including diet and lifestyle changes. If a patient is committed to these changes then gastric surgery is a fantastic option and what better place to recover than in the French climate. Photo Credit: © aihumnoi - Fotolia.com
