Evaluation of Food Additive Contributions to Obesity - Feasibility Study 1

August 18, 2019 updated by: Natalia McInnes, McMaster University
The effects of food additives on body weight in humans are largely unknown. This is a before-and-after feasibility study in 5 obese adults who will be followed for 5 months. Eligible participants will meet with the study team and will be taught how to limit the exposure to the studied food additives in their diet. Participants will also be asked to limit eating out to a maximum of 2 days per week. Primary outcomes in this study are recruitment rate, retention rate and adherence to the proposed dietary intervention.
