Everyone’s different. I do OMAD and one 72 a month. When I refeed I literally load up to 2000 calories per sitting. My staples are red meats and potatoes and whole milk. I did have GI issues until I started my OMAD. My doc said fasting has lowered my hypertension blood pressure to healthy levels and cholesterol is down. I’ve lost a healthy 33#s in three months. 253 starting /current 220. I’m at a comfortable weight. I just didn’t think I would hit it that fast. I don’t workout just construction. The OMAD is actually giving me 2.5hrs extra pay a week also for not taking dinners. I’m really surprised but eating once a day eating 2000 calories I feel so energized in the day.
