Muscle Retaining

I have gotten thick thighs, and a nice butt, I train legs and glutes only. I never cared about muscle until I saw how good I look with thick thighs. I eat 160+ grams of protein a day.

I miss fasting on a schedule, refeeds on Sunday with my family, the energy, a clear mind; I can’t believe I stopped, I can’t wait to start again.

Is it difficult to build muscle doing consecutive fasts? I used to do: Monday omad (large salad) ,2 day fast, omad, 2 day fast, refeed (eat whatever I wanted on Sunday), repeat.

Someone posted their schedule and it was 6 days fasted, one day refeed, I would think that’s difficult to maintain muscle. Does anyone maintain substantial muscle fasting? What does your schedule consist of?
