KEY TO WEIGHT LOSS- CALORIE

KEY TO WEIGHT LOSS- CALORIE

Curbing calories is the key ingredients for diabetics seeking to lose weight, and low-fat diets that are either high in protein or high in carbs are equally effective, researchers say. “I think there are two key messages from this study,” said study lead author Jeremy D. Krebs, a senior lecturer with the school of medicine and health sciences. “The first is that no matter what diet we prescribe, people find it extremely difficult to sustain the changes from their habitual diet over a long time. But if they are able to follow either a high-protein diet or a high-carbohydrate diet, they can achieve modest weight loss.”

                Krebs said this first message conveys flexibility and allows people to choose the approach that best suits them and “even to swap between dietary approaches when they get bored.” The second point “is that for people with diabetes, if they can adhere to either diet and achieve weight loss, then they do get benefits and cardiovascular risk,” he added. To compare the potential benefits of two popular dietetic approaches, the authors tracked nearly 300 overweight men and women between the ages of 35 and 75 who were on a new, two-year nutritional program.

                To start, all the participants had a body mass index greater than 27, meaning they were moderately overweight, and all had type 2 diabetes.

                The researches randomly assigned the participants to one of two groups: a low-fat/high-protein group or a low-fat / high-carb group. For the first half year, all attended twice-weekly group sessions led by a dietitian; for the following six months, sessions took place monthly.

                Weight and waist circumference were measured at six months, one year, and two years. Kidney function and lipid (blood fats) profiles were also assessed throughout.

                Food diaries indicated that total calorie intake went down in both groups. Ultimately, both groups lost similar amount of weight and reduced their waist size in similar measure, the investigators found. And by the end of the two-year period, both groups had similar blood fat profiles.

                Krebs and his colleagues concluded that their “real-world” experience demonstrated that both approaches afford similar benefits, with the principal driving factor behind sustained weight loss being calorie reduction rather that either high-carb or high-protein consumption.

                Experts note that research presented at medical meetings is considered preliminary because it has not been subjected to the rigorous scrutiny required for publication in a peer-reviewed medical journal.
