Researchers in Belgium have found that exercising in the very early hours of the morning can help the body to burn more fat and potentially keep off weight gain, compared to exercising at other times. In the study, researchers had young, healthy men to gorge themselves for 6 weeks with a diet consisting of 30% more calories and 50% more fat than what they had been eating prior. The first group of the volunteers remained sedentary while eating. The second began a strenuous, midmorning exercise routine after they had had breakfast while the third group followed the same workout regimen, but before they had eaten anything. After the 6 weeks, the first group predictably had gained the most weight, at 6 pounds, and had begun to develop insulin resistance. The second group gained 3 pounds and also developed insulin problems. But the third group of men gained almost no weight and retained healthy insulin levels. Their bodies were also burning more fat throughout the day than were the other men. It is important to note though that the early-morning exercise prevented weight gain, which is not the same thing as inducing weight loss. But the results are encouraging to anyone who is looking to have a healthier lifestyle. Does this study motivate you to work out early in the morning? What about in this weather?

A new study lead by BBC Science and obesity experts explains every person has different eating habits and specific diets are needed for each person based on their hormones, genes,cognitive behavior etc. Instead of following a standard diet it is important to focus on your eating habits first to develop a diet specific for you. Scientists from Oxford and Cambridge followed and observed eating trends of 5 dieters for three months in their homes. The study looked at three types of over eaters, feasters, constant cravers and emotional eaters. The study found diets are based off habits. The feasters, people who have a hard time stopping eating, have a problem with their gut hormone balance. Constant cravers, people that are always hungry, have certain genes that disrupt the signals sent to the brain so they do not know when they are full. Emotional eaters eat when they feel anxious or stressed which is a habit they have developed. Overall, feasters lost the most weight and constant cravers had the hardest time losing weight. Dieters learned what type of eater they were and experts came up with plans to help them change their eating habits and practice the best diet for them. Although personalized diets are a new trend, experts say there is a lot of potential to help people lose more weight once they know more about their own body and how it affects their eating habits. Depending on the type of eater you are determines the type of diet you should try.

The study that supports the use of green coffee bean extract for weight loss and was promoted in Dr. Oz’s Show as the “Magic weight loss cure”, has been retracted by its authors. They explained that the sponsors of the study, the green coffee bean extract manufacturer, could not assure the validity of the data. Moreover, the company, Applied Food Sciences Inc., has been charged by the Federal Trade Commission for using the results of the flawed study to make baseless claims. What are your thoughts about weight loss products and specifically green coffee bean extract? What other products are you uncomfortable recommending?

A recent analysis evaluated an association between fiber and reduced disease risk using 28 studies on diabetes, 33 studies on cardiovascular disease and 19 studies on obesity. Researchers found that people consuming fiber-rich diet had 18 to 40 percent reduced risk of developing diabetes compared to people who did not eat high amounts of fiber. Less stroke risk and death from cardiovascular disease was also tied with high fiber intake. Eating more fiber-rich grains was also associated with a small but significant weight loss. Although, the study found a benefit with fiber-rich diet, an amount of fiber is yet to be determined. Based on all the data out there, how much fiber do you recommend your patients to consume daily?

The Laryngoscope recently published a study regarding the relationship between hearing loss and teen obesity which reached epidemic proportions in the US. Researchers looked at 1,488 overweight boys and girls between ages 12 to 19, coming to conclusion that hearing loss is another health risk in this population. The hearing loss might occur due to inflammation caused by obesity and will progress from one ear to both in adulthood. What weight loss strategies do you recommend for obese teenagers?

A study published in the New England Journal of Medicine evaluated the efficacy of weight-loss intervention in patients with serious mental illness, such as schizophrenia. This population is generally overweight, with many of the commonly used medications causing weight gain. Researchers in Maryland conducted a study of 291 obese patients with mental illness, randomizing one group to receive weight loss intervention therapies (i.e. individual and group weight management class, exercise, and dietary changes) with the control group to receive a traditional nutrition regimen. The intervention group consistently lost weight over the 18-month trial period, showing that these patients can be successful in losing weight when lifestyle interventions are made. In what other patient populations have you personally found behavioral modifications to be helpful in weight loss?

A new study published in the International Journal of Obesity, Timing of food intake predicts weight loss effectiveness, evaluates the relationship between meal time and weight-loss. The authors followed 420 patients in Spain during a 20-week period where lunch is the biggest meal of the day. Participants were grouped into early eaters who ate lunch before 3 pm and late eaters who ate lunch after 3 pm. The study showed early eaters lost 25% more weight than late eaters. The authors concluded the timing of the largest meal affects the success of weight-loss regimens. When discussing nutrition habits how often do you stress meal times?
