Weight Reduction With the Low-Insulin-Method - Self Monitoring of Breath Acetone

Background: Overweight and obesity are an increasing problem. 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, physical activity, self monitoring of weight, and self-monitoring of breath acetone (SMBA) is examined compared to a control group without information about ketosis level. Weight change will be compared after 3 and 12 months. 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.
