I fast 4 days a week. "Hunger" that most people refer to is simply a disregulation of glucose and insulin. Hunger is something you feel in your throat not the stomach. 

What you are feeling is regulation of your ATP through ketosis which feels like stomach satiety. Your body has given up looking for glucose through carbohydrates and has begun using stored fat and muscle. 

 Most I’ve done is 2 days, only once.  4 days is impressive. 30 days+ is baller. 

 The most I've done in a row is 14.(I was so cranky my wife made me eat.) I do 2 days fast, 1 day I can eat, then 2 days fast, 2 days eating. It just takes the idea that "I can eat whatever I want in two days." It keeps me going.  

 Damned impressive 😎 

 That's amazing. The most I've done is a day. I usually end up eating because I see other people eating.  

 Having the power to tell yourself "Out of all the things I can and can't control about what happens today, not eating anything is firmly in my exclusive control." Is one of the most powerful feelings that reorients my brain for more possibilities in my life. Definitely worth training that skill. 

 I love it. That's a powerful perspective.
