i'm 3.5 weeks out and still on liquids until next week. (my diet seems longer than most others i read about). i cheated by starting purees about a week early, at the 3 week mark instead of the 4 week mark. i had some mashed sweet potato with greek yogurt one night and then last night i had refried Beans with greek yogurt and a few slices of mashed avocado.
i also ate a few bites of a Protein bar instead of a shake one morning this week - i chewed it until it was liquified and swallowed it and it wasn't worth it, i won't do that again. i felt fine but it tasted so gross to me to chew it for that long. i'll just wait until i can have regular food again to eat a protein bar!
calorically, i haven't done any 'cheating.' i've just fast-forwarded my plan a little bit due to the sheer insanity that comes with only drinking liquids for 5 straight weeks (i had a 2 week pre-op too!). i feel ok about it. puree stage has a lot of flexibility so i don't plan on cheating for my puree weeks!
