Burns and Miyashita that physical activity is a vital component of weight management and cardiovascular health. In our clinical trial, physical activity levels did not significantly differ between the groups at baseline or during the intervention. Although it was not the aim of our study, future studies should examine whether physical activity levels modify the differences in efficacy of low-fat and low-carbohydrate diets.Drs. Donzelli and Lafranconi raise several concerns about low-carbohydrate diets. They note that a meta-analysis showed that low-carbohydrate and low-fat diets were similarly effective for weight loss at 12-month follow-up ...References1.
