My lifelong preference is to eat two meals a day. Late breakfast and dinner 8 hours later. That’s almost what’s recommended here.
500 calories a day? I’d fade away to nothing, only weigh 112 now.
I’m on the 5:2 plan.
I fast 2 days a week usually Monday and Thursday. Eat normally the other 5. Usually one meal only. Sometimes more than that.
I’ve lost 40 pounds since I started last October. Intermittent Fasting works.
