It'll be healthier and more enjoyable just to eat actual food

I tried that. It didn't work.

Could you be more speciifc? (In particular with respect to macronutrient ratios, and whether you've ever been in ketosis and confirmed it with a blood or urine test.) I have a strong prior against people having tried all the things, even if they've tried to try them, since some of the strategies are easy to do incorrectly without realizing it.
