As I have been doing intermittent fasting daily, I have realized a few things that were surprising to me.
1) I can function well on less food, in fact I feel better if I'm never actually full.
2) The feeling that I used to consider "full" or satisfied was really just the sensation of my body digesting a meal. When my digestive system finished with that task, I always assumed I was hungry. I wasn't, I was just no longer digesting the last meal. That light, unburdened feeling is one that I am learning to love.
3) Hunger is a different sensation, when the body needs nutrients and goes looking for them. I'm able to tell the difference now that I've experienced both. I'm more likely to be comfortable throughout the day now that I'm not in a cycle of feeding to stay full.
