Dietary carbohydrate rather than protein intake drives colonic microbial fermentation during weight loss

High protein weight loss diets are effective in aiding body weight management. However, high protein and low carbohydrate intakes can alter colonic fermentation profiles in humans and may impact on colonic health. This study aims to identify the most important dietary contributors to colonic fermentation during diet-controlled weight loss.Overweight or obese male volunteers (n = 18) consumed a body weight maintenance diet (fed at 1.5× basic...
