Background: Overweight and obesity affect health, quality of life and ability to work. Therefore, the Low-Insulin-Method was developed to support overweight and obese people in weight loss. Method: In a randomized controlled clinical trial, the effect of the lifestyle intervention program 'Low-Insulin-Method', delivered by the Low-Insulin-App including low-carb diet, self monitoring of weight, physical activity and telemedical coaching is examined compared to a control group without coaching. The learning contents are taught in 30 videos and 5 online meetings. The intervention group additionally gets 4 individual care calls. The state of health is examined at the beginning and after 12 weeks. Objective: The aim is to develop a training and counseling program for overweight or obese individuals with diabetes risk or type 2 diabetes, which can be used both for primary and for tertiary prevention of overweight-related diseases.
