The entire time to prep, cook and clean is ~15m per day, if your feeling really lazy you can cook multiple days worth of food at once and it's still 15m once and you have food for multiple days.

Cleaning is a single pan (or whatever you used). Most adapted carnivores only eat once per day (just by feeling, not forcing themselves).

If you are lazy, you can't do better then carnivore. Even ordering food takes more time.

Plus... meat in the freezer lasts forever... if you don't want to cook, no rush.
