I only do walking, and I do a lot in work, miles, literally! I only fast on non working days because of that much. I can't run because my knees only hurt when I do. I know I do enough exercise through the week as I have sought advice for it to see if I needed to do more. I think that because of my lifestyle, my stomach just won't do two quick meals, because I usually eat a small meal then a small piece of fruit till next meal. Having only three small meals in a day is something I haven't done in quite a long time. Because I don't have cravings and am not hungry at anytime, I think that because of trying to cram a usual days food into a small time is too much for me. Thanks for your suggestions! I think it will do me good in the long run. But I'm only just learning how to do intermittent fasting! If I didn't have to eat I would be happy!
