The effects of food additives on body weight in humans are largely unknown. This is a feasibility study in 10 obese adults who will be followed for 5 months. Eligible participants will be non-randomly assigned to 2 groups and will be taught how to limit the exposure to the studied food additives in their diet. Primary outcomes in this study are recruitment rate, retention rate and adherence to the proposed dietary intervention.
