One observation from personal experience with prolonged intermittent fasting: My metabolism slowed down quite a lot. After nearly 10 years of eating once per day, my resting metabolic rate was 3-400 calories lower than average. Whether that's a bad thing or not, I have no idea. My grocery bills were certainly low. And it saved a ton of time on meal prep. More recently, I became too physically active to maintain that diet and returned to eating 3-4x a day. My metabolism has steadily returned to baseline since then. It took about 6 months but it is now essentially back to normal.
