I think a very small amount of calories over a very long time would hurt your metabolism - slowing it and leaving you in a bad situation. Eating no calories over the same long period of time would provoke the body’s survival mechanisms - muscle preservation, pure fat burning, autophagy etc. I think you would have more muscle (and less body fat) at the end of a pure water fast than a restricted calorie diet.

You are coming off like a protein powder salesman or a “bro science” body builder type because you haven’t looked into the body’s reaction to water only extended fasts.
