I fast regularly and have a 5-6 hour eating window. During that window I just cannot eat more than 1500 calories. If typical caloric reduction can trigger starvation type response in the body, why does it not happen when we reduce calories during fasting?
Caloric restriction does not lead to an increase in Human Growth Hormone. There are a bunch of other hormonal changes that occur when the caloric input is zero, versus when it is something. That’s why study after study shows fasting is superior to caloric restriction.
