On a good day? Start with protein (a shake, sardines, eggs, etc) or veggies (carrot sticks, salad, etc).
On a bad day? Chocolate, peanut butter, cookies, whatever’s in that cabinet.
Keep that cabinet filled with good stuff.
I break with just straight up meat. Chicken, beef, fish, whatever’s handy, with either nothing or maybe I dip it in a lil sauce, like it’s a chicken nugget. I’ve found I almost never have stomach issues this way, even after a 3 day fast. (Note: never break a 3 day fast with pizza) Then I eat some veggies, then whatever I want.
