Studies on high-carbohydrate diets and physical endurance in runners show dietary carbs increased maximum endurance, even though fats have more than twice the energy of carbs. How could this be true?
1.Dietary fat isn’t used directly for energy.
2.Aerobic activity relies on glucose for energy.
3.Energy from fat metabolism is released by a slower path than carbs.
4.Dietary fat isn’t used directly for energy & aerobic activity relies on glucose for energy.
5.Aerobic activity relies on glucose for energy & energy from fat metabolism is released by a slower path than carbohydrate.
