I train 3-4 times a week (calisthenics). I tried 5 days of intermittent fasting for 5 days. I was DYING for food in the morning even on the 5th day, I drank way too much coffee, and in the end what really convinced me I had no reason to keep on doing this was HOW BAD AND SICK my (normally fine and healthy) breath smelled. Like, friends felt compelled to actually ask me why that was the case (yes, good friends will tell you if you have smelly breath). I suppose it was because I quickly went into ketosis, but overall it wasn't a pleasurable experience. I went back to my regular balanced breakfast as part of my varied vegetarian diet. I guess IF just doesn't cut it for me and maybe I don't have the patient to turn myself into a smelly monster just to follow some popular nutrition fad, especially considering I'm well into my weight and I have low body fat. Just my 2 cents. Internet doesn't convey smells yet, and that's great news for all the crowded fasting online communities out there, I guess.
