@Munchkin, there's a lot of pretty decent info out there on IF.. however, most I read suggest an "eating window" of 6-8hrs.. I think even normies struggle with the "Warrior Diet" deal of a 3 hr or less 1 mega-meal/day- if for nothing else than, damn.. that would be uncomfortable! I don't personally find IF uncomfortable or a "diet" of the fad type- I naturally seem to fall into the routine of eating after about 12-14hrs of not eating.. no hunger until then,
provided I've been eating enough fat, and not overdoing the carbs. It comes down to, imo, if you are hungry- eat, if not, don't- I don't intentionally IF, but some days if you count that I don't eat until after noon- I am by default IFing.
I never knew DSers did fat-bombs, I thought that was strictly normies who were following a LCHF or keto way of eating to get in needed calories for weight maintenance..- big calorie load in a small package. Just as some suggest they have a significant metabolic derangement, needing the surgical reset of the DS, some (like me, through trial and much error) have discovered that my tolerance of carbs is not that great, and I feel and function best/don't gain/can easily lose if I adjust carbs down and fats up.. If I exceed a certain level of carbs in my diet.. I have consequences, so the macro I play with the most is fats. When I want to lose- I reduce carbs and fats a bit as needed (usually the gain is from too much carb), when I want to maintain- I up the fat. I have not personally had any need or want to do "fat bombs" or drink oil! I'm happy enough adding butter, eating chicken skin, and the crispy bits from untrimmed ribeye!
From what I can gather, most DSers by default have lowered carbs post-op.. just due to protein and fat forward diets? Please correct me if I'm wrong- I just am assuming, from what I've read- since most say- focus on protein, don't worry about fat.. and stay away from carbs from things like sugars and grains until the weight is off, then slowly test the waters from there..
