Intermittent fasting can carry great benefits if done right. These include weight loss, reversal of type 2 diabetes, increase in energy, etc.
Note, intermittent fasting does not mean starving yourself. Fasting simply allows your body to burn off excess body fat. Body fat is basically food energy that has been stored. Therefore, if you don’t let your body will counteract this by “eating” its own fat for energy.
When you eat, more food energy is ingested than can be immediately utilized. Some of this energy is stored away for later use. And insulin is the core hormone involved in storing food for energy. Your insulin levels rise when you eat, helping you store excess energy into sugar and fat.
Insulin is linked to glycogen and then stored in the liver. However, the liver can only handle so much, and therefore the liver starts to turn excess glucose into fat.
When you fast your insulin levels fall, signaling the body to start burning stored energy. Blood glucose falls, so the body must now pull glucose out of storage to burn for energy.
If you eat immediately after waking up, and do not stop until you go to sleep, you spend almost all your time feeding yourself. This does not give your body enough time to burn food energy. Try eating your first meal at 11am or 12pm. Stick to smaller portion sizes, and be sure to eat plenty of protein to ensure you don’t lose any muscle mass.
