Overview
Brief Summary
Weight loss maintenance is the biggest challenge in obesity management, with the majority of weight-reduced individuals experiencing weight regain. The intake of probiotics has been shown to help in weight loss, but its potential in maximizing weight loss maintenance remains unknown. Therefore, the main aim of this study is to investigate the impact of probiotic consumption on weight loss maintenance. Secondary aims are to investigate if the intake of probiotics influences gut microbiota, cardio-metabolic profile, appetite and inflammatory markers.
