This is how I do it:
Shop once a week. Eat all your fresh food first. Then move on to what's ripened. Then eat the stuff in the fridge before it goes bad. By Friday you're out of food and can have a fasted day before groceries. It's what we usually do. Same volume of food, eat most of it in three days (feast) and stretch the rest out (famine) as long as you can. Then you get to stuff your face and feel great, alternated with a pleasant pseudo/actual fasting time - during which you will also feel great because you're adequately nourished from days 1 through 3. Call it cycling or whatever you want. It works really well.
Yeah, I was sort of eating disordered. But mostly malnourished. So take it as it is, from a person who grew up overweight and ALWAYS hungry, even when stuffed.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
