4k a day is EASY on IF IMO. At 1500-2k cal for a meal, I am needing to pump the breaks and leaving the dinner table hungry.

I wish my metabolism could support eating even 3-4k calories a day.
Additionally what is clean? Plain chicken with nothing on it, and a plate of broccoli? That isn't what IF is about. The whole concept of IF is progressive, and breaking typical "dogma" of what has been preached all these years. For me sitting down with a lb of chicken, having it on a bagle thin, with BBQ sauce, a big ass salad with low fat dressing, box of mac and cheese made with almond milk/low fat smart balance butter, veg, and finishing it off with some low fat ice cream on top of some low fat eggo's is perfectly clean.

I have my macro targets and I stick to that. If it is a low fat mea/carbl I hit that with LEAN protein some tasty carbs(pasta, white rice, white/red potatoes, etc) and if I have carbs to spare I have no issue having a dessert, if I can fit the macros in and adhere to macros(keeping it low fat)
Tonight post workout, I had half lb of 96% lean gb(burger) on a bagel thin, bbq sauce/lettuce, half lb chicken breast, alexia rosemary and garlic fries(low fat), a big salad, asparagus, and dessert was a split banana topped with 2 skinny cow "caramel cone" ice cream cups, FF whipped cream, crumbled low fat vanilla wafers, FF chocolate sauce, and a little pb2(low fat PB) made into a sauce with almond milk.
Clean doesn't have to = boring.
You don't even wanna see a refeed. I am like a bottomless pit.
