Starvation is not sustainable. Fasting is not a way to lose weight quickly. If the body is regularly denied food, it goes into starvation mode where the metabolism is slowed down. This means that whatever is ingested goes straight into storage- the scale may drop but body fat increases and muscles mass decreases. Fasting also means that when you do eat you tend to overeat- either you’re so hungry you just want everything, or you over portion as a result of consistent hunger. Moderation and consistency are the keys to sustainable weight loss, not denial and avoidance.
