OMAD Schedule: One Meal A Day Fasting Plan + Sample Meals
OMAD compresses all daily eating into one meal — typically a 23:1 schedule. It's simple, requires zero meal planning beyond one large dinner, and brushes the edge of where mild autophagy starts. It's also the easiest IF protocol to under-fuel on, so structure matters.
How OMAD works
Most people eat OMAD at 17:00–18:00, allowing roughly an hour to eat. The meal must be substantial — half a plate vegetables, two palms of protein, a fist of complex carbs, healthy fat. Outside the meal: water, black coffee, plain tea, electrolytes.
A sample day
- 07:00Wake. Water + sea-salt + magnesium.
- 12:00Black coffee. More water. Hunger peaks.
- 16:00Walk or light movement.
- 17:00OMAD meal — large, balanced, slow.
- 18:00Close window. Stop eating.
- 18:00–17:00Fasting window. Water and tea.
What happens in your body
Physiological milestones reached during a 23-hour fast.
- h4
Blood sugar normalizes
Insulin drops back to baseline as your last meal finishes digesting.
- h8
Glycogen burning begins
Your liver starts releasing stored glycogen to keep blood glucose steady.
- h12
Glycogen depletion
Liver glycogen runs low; the body shifts toward fat for fuel.
- h14
Fat burning accelerates
Lipolysis ramps up — stored triglycerides break down into free fatty acids.
- h16
Mild ketosis starts
The liver begins producing ketones from fatty acids. Mental clarity often improves here.
- h18
Growth hormone rises
HGH increases up to 5×, supporting muscle preservation and tissue repair.
- h24
Autophagy begins
Cells start digesting damaged proteins and organelles — the housekeeping phase.
What to eat
Build the OMAD plate with: 60–80 g protein (two palms), half a plate of vegetables, a fist of starchy carbs (rice, potato, quinoa), 1–2 thumbs of fat (olive oil, avocado, nuts). Add fruit for dessert. Eat slowly — 30 minutes is the sweet spot.
How to break the fast
- Steak with roasted root vegetables, large salad, and rice
- Salmon, sweet potato, broccoli, mixed greens, avocado
- Chicken thighs, lentils, roasted carrots, yogurt with berries
- Lamb curry, basmati rice, spinach, mango chutney
Who it's for
- • People who hate decision fatigue around food
- • Experienced fasters comfortable with 18:6 or 20:4
- • Those targeting fat loss with strong appetite control
Benefits
- • Brushes the start of autophagy at hour 24
- • Strong growth-hormone surge
- • Logistically simple — one meal to plan and prep
Risks & cautions
- • Easy to under-eat — track the first 2–3 weeks
- • Hard to hit protein goals in one sitting; aim for 60–80 g at the meal
- • Disordered eating risk if used as restriction rather than structure
- • Sodium and magnesium needs are real; supplement at first sign of headache or cramps
