The Addition of Probiotic Consumption to a Nutritional Intervention and Caloric Restriction on Body Weight and Composition in Overweight Participants
August 31, 2020 updated by: Angelo Tremblay, Laval University
The Addition of Probiotic Consumption to a Nutritional Intervention and Caloric Restriction on Body Weight and Composition in Overweight Participants: A Randomized, Double-blind, Placebo Controlled Study
Limited interventional human studies suggest that probiotic supplementation may be a beneficial strategy for promoting weight loss when added to a nutritional intervention via their effects on lipid absorption and metabolic signaling molecules.
The purpose of this study is to evaluate the effects of addition of a probiotic supplementation to a weight loss intervention on body weight, body composition and overall health in overweight adults.
