Increased carbohydrate and fibre intake, as part of a plant-based high-carbohydrate, low-fat diet, are associated with a reduction in weight, BMI and fat mass and improved insulin resistance

In September 2018 researchers from the USA published the results of their study to assess the role of changes in carbohydrate intake on body composition and insulin resistance in overweight individuals. A total of 75 individuals were involved in the study, with 38 consuming a plant-based high-carbohydrate, low-fat (vegan) diet and 37 maintaining their current diet. Body composition and insulin resistance was assessed at the start of the study and again after a 16-week period. Results showed that weight decreased significantly in the vegan group as did insulin resistance. A further analysis revealed that the increase in both carbohydrate and fibre intake resulted in a reduction in BMI, fat mass and amount of visceral fat.
