hey kyle -
ive read that ppl have been successful with IF even a couple times a week. the idea is to make it work with your schedule - be it 1-7 d/wk - youll still get the benefits.
perhaps consider varying the lengths of your fasts, too. do the fast 5 some days, and then allow a longer feeding window on other days (e.g., up to 9 hrs) so that you don't always feel like youre stuffing yourself. for example, i generally eat 12-8 daily, which allows for the daily fast and a "regular" social schedule.
so, if you'll following zonish proportions - then yes, you eat that every day regardless of the time in which you eat it. if youre still stuffed from the night before, then ease into the next day. eat ad lib. although - with a frequent IF, you may find you don't need quite as much food to maintain your mass.
i keep pointing ppl to this thread - but steve summed up IF and training pretty well:
i find strength workouts tough on a long fast, and metcon pretty easy. others may say the opposite - you'll have to see what works best for you.
