Thank you all for your input on my questions.
I may have to rethink OMAD and switch it up occasionally.

Intermittent fasting with OMAD was very effective, until it wasn't.
But to be fair, I wasn't staying very low-carb and some bad foods got back into the daily meals. I still lost weight tho.

When I went back to eating 3 meals a day and snacks. Bad foods stayed in my diet. (bad choice) weight came back very quickly. I can't help but wonder if my success would have continued, if I had stuck with the OMAD.
