One? Never mind. I have 32 studies with equal protein and/or calories, and the pooled weighted mean difference in energy expenditure of 26 kcal/day. Dietary carbohydrate ranging from 1%–83% and dietary fat ranging from 4%–84% of total calories.

Greater body fat loss in was in favor of the lower fat diets but the effect sizes are so small as to be physiologically meaningless.

How do you explain the results of 32 studies going in the opposite direction to the predictions of the carbohydrate-insulin model? (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5568065/)

And by the way, we see the exact same thing between high and low insulinemic diets—same weight loss when calories are matched.
