Frequently Asked Questions — Intermittent Fasting Calculator
Is OMAD safe?+
OMAD is safe for most healthy adults if done correctly. Requires 4-8 weeks adaptation. Not recommended for: pregnant women, those with eating disorders, type 1 diabetics, or people on certain medications.
What to eat on OMAD?+
Your single meal should contain: 0.8-1g protein/lb bodyweight, healthy fats (30-35% calories), complex carbs. A large salad + protein + healthy fat + vegetables works well.
