More contentious is whether ketogenic diets have any utility for exercise performance, especially among high-level athletes. Ketogenic diets are characterized as being very low in carbohydrates (less than 50 grams per day), modest in protein, and high in fat (more than 80% of total energy intake). What are ketones?
Poor sleep is associated with worse diet quality, and sleeping less causes people to eat more — and more of the wrong things.
