Olympic weightlifters and marathon runners have different requirements. It’s not a one size fits all solution. Biological variability. Someone lifting weights would ideally eat every ~3 hours to avoid catabolism in any capacity. Someone who lives a moderate lifestyle looking to maximize longevity and minimize Mtor pathway expression may participate in intermittent fasting. Its result oriented, is a better way to look at nutrition. What is your goal? Then work retrospectively from there. Even day to day, your body has different needs. It’s silly to view a system as dynamic as the human body as a system that has the same requirements everyday when your sleep, your calories burned, etc vary.
