Really? Everything I've seen has shown that calories are the primary factor, and too many (or too few, but that's not much of an issue in the US/Europe) of them from any source lead to poor health. I've seen people get good results with high carb/low carb/keto, intermittent fasting/eating every two hours, or avoiding wheat/having a bread-based diet, but I've never seen any diet that produces good health or performance with too many or too few calories, regardless of the eating strategy or ingredients.
