I practice undereating/intermittent fasting everyday (16-18 hours, this includes time spend sleeping at night ). My energy levels are sky high. I am not a competitive racer but I am extremely active physically including commuting on my bike everyday all year round. I have a daily feeding window which starts at around 2:30 and runs till 9:00. I can easily consume 2500 calories within those last 6-7 hours of the day. My only snacks during the undereating phase are either fresh fruit or a small amount of cottage cheese with few tablespoons of olive oil.
