Here's something from my experience, it's not based on any research or someone's book, it's literally entirely subjective so who knows if it's even helpful: for me, intermittent fasting had effect when it was entirely irregular. If my body didn't get a chance to notice the pattern, that's what made it behave different. Same goes for exercise, if I do regularly one type of exercise - body quickly gets used to it and it's harder to achieve gains by doing the same movement. What I do is irregular fasting. Sometimes I won't eat for 30 hours. Sometimes I'll eat 6x a day. Sometimes it'll be eating at 11:00 and next meal is 12 hours after. These are not guidelines, just examples of irregular intervals. I noticed results, it could have been placebo, who knows, I have no means to measure except subjective feeling. If you're capable of enduring hunger, you could try it. It might be dangerous so don't listen to random advice from a nobody online :) anyone reading this and trying what I wrote out: it's not my fault if something happens to you, I'm not a medical doctor.
