Question special

I think the carbohydrate consumption in both groups was quite high accounting for about 50% of total calories. We know that carbohydrates drive weight gain by triggering the release of insulin which is the fat storage hormone. My thought is that one of the reasons there was not much difference between the 2 groups is that their carbohydrate consumption was similar. I think we have to start focusing more of the type of calories that we eat rather than the amount because the different macronutrients have very different effects on our metabolism. I'd love to hear the authors' thoughts on this. Thank you!
