Macronutrient Relations and Weight Loss in Obese Subjects

Effects of Macronutrient Relations on Body Weight, Body Composition, and Cardiovascular Risk Markers in Overweight Patients Attending a Telemedically Guided Weight Loss Program

The burden of overweight and obesity has dramatically increased during the last decades. High carbohydrate intake, particularly refined carbohydrates, probably increase the risk of obesity, type 2 diabetes, and metabolic syndrome. There is evidence that energy-restricted low-carbohydrate diets show greater weight loss and better improvement of cardiovascular risk markers compared to energy-restricted low-fat diets. Beside macronutrient relations, efficacy of weight loss programs depends on care and control. The investigators aim to investigate whether or not a carbohydrate-restricted telemedically guided weight loss program results in a more pronounced weight loss and influences metabolic risk markers more beneficial than a fat-restricted diet.
