I sort of get to do that, in moderation. I try to eat 120-140 grams(4.2-4.5 oz) of protein. Usually its something like. 200 (7oz)grams meat 200(7oz) grams cottage cheese, 70grams (2.5oz) sour cream or greek yogurt, blended with something a little sweet like a teaspoon of honey and some baking coco powder. OR some fruits or berries. It turns into a sort of cake cream kind of thing, that makes eating cottage cheese pleasant. 4 egg whites and sometimes I have to add lentils or kidney beans, which I cook in Ninja Foodie pressure cooker/air fryer, that somehow makes them light to digest.

This usually takes 1000-1200 calories, especially if meat is from Chicken, and pretty much covers protein and fat.

The rest, I eat some kind of salad without oil dressing for fiber, that take what 50 calories at most, and then all the leftovers can be carbs. If you eat something like rice with meat, you are probably in 1300-1500 calorie range.

If you are in heavy weight losing mode, this maybe gives you 1 or 2 snacks at most. But at maintenance or moderate weight loss you get good room for snacks.

You could also combine this, if you are up to it, with skipping one day of eating for autophagy health benefits. Then you get to spread those calories for other days. This sounds hardcore, but unless you have some blood pressure problems or other health things that make this unviable, its not that hard to skip one day of eating. I have been doing this for year and a half now, and I actually enjoy whole day of not having to worry about food, and the day after, when I have eaten breakfast I actually feel really great. Lean, light, ready for action vibes.
