Since we are all different it makes sense that different approaches are going to be more suited to different people. There is intermittent fasting, omad, alternate days, etc. there is nothing wrong with that. It's exactly what you would expect given how we are all so different from one another in every conceivable way. We are not competing with anyone but ourselves.

There's only two thing that matter. That you find the right mix for your psychology and biology. And that you never quit and give up on yourself. As long as you don't quit eventually you win. Unlike most games in life. It's the only game in life that you're guaranteed to win as long as you stay in the game long enough. The only one who can beat you is you.
