OMAD & 20:4 Intermittent Fasting Protocol (230 lb Male)
Heavyweight 20:4 time-restricted feeding blueprint for a 104.3 kg (230 lb) male lifter: 2,200 kcal, 180g protein, and 4.0L hydration.
A 230 lb male (25% body fat, 172.5 lb LBM) on OMAD (20:4 protocol, 4:00 PM to 8:00 PM) should target 2077 kcal with 180g protein. Drink 4.0 liters of water with 4,000mg sodium during the 20-hour fast to eliminate hunger pangs and drop 1.4 lbs of fat weekly.

Visual Intermittent Fasting Clock & Loss Curve
Interactive 24-hour chronobiological dial mapping insulin nadir, fat oxidation, and autophagy milestones while safeguarding skeletal muscle mass.
24-Hour Circadian Fasting Clock
Drink at least 2.5–3.0 Liters of water with 1,000–1,500mg sodium during the fasting hours. Low insulin drives rapid renal natriuresis (salt dumping); without electrolytes, fasters experience headaches, orthostatic fatigue, and false hunger cravings.
The 4 Circadian Stages of Intermittent Fasting
What physiological mechanisms occur inside your cells as fasting duration advances across 24 hours:
Digestion & Postprandial Storage
Nutrient absorption, insulin secretion, muscle glycogen & triglyceride synthesis.
Postabsorptive Glycogen Transition
Blood glucose normalizes; hepatic glycogenolysis sustains 75% of cerebral glucose requirement.
Accelerated Lipolysis & Ketosis Onset
Hepatic glycogen stores depleted; adipose triacylglycerol hydrolysis accelerates.
Autophagy & Cellular Recycling
mTORC1 suppressed; lysosomal autophagosome degradation of damaged organelles and senescent proteins.
Projected Weight & Body Fat Loss Curve
Incorporates adaptive metabolic thermogenesis (-10 kcal/kg lost) and protocol-specific lean mass partitioning.

Clinical Nutrient Standards to Hit Your Calculated Targets
Micro-Filtered Grass-Fed Whey Isolate Standard
28g Protein • 3.3g L-Leucine • <0.2g Lactose • 110 kcal
Delivers 28% of your 198g daily protein target in two low-volume servings while crossing the 3.0g leucine mTORC1 trigger.
Free-Form Essential Amino Acids (EAA) + Soluble Prebiotic Fiber
3.5g L-Leucine • 8g Partially Hydrolyzed Guar Gum • Zero Gastric Heaviness
Engineered for patients experiencing early satiety on Semaglutide or Tirzepatide who need maximal myofibrillar preservation without meal volume.
Micronized Creatine Monohydrate (5g) + Quantitative Electrolytes
5g Pure Monohydrate • 1,000mg Sodium • 200mg Potassium • 60mg Magnesium
Supports intracellular water retention, ATP resynthesis during resistance training, and electrolyte balance during fasting or sauna protocols.

Clinical Analysis: OMAD & 20:4 Intermittent Fasting Protocol (230 lb Male)
For a 230 lb male with 172.5 lbs LBM, OMAD provides substantial appetite suppression and aggressive fat mobilization. Pacing 180g protein and 2,200 kcal into a 4-hour evening window stimulates overnight cellular repair while producing a daily 800+ kcal deficit.
Key Execution Takeaways for This Profile
- Maintain a 20-hour fast (8:00 PM to 4:00 PM) with 4.0 liters of fluid.
- Split your 2,200 kcal intake into two feedings within the 4-hour window.
- Consume 4,000mg sodium and 500mg magnesium to avoid muscular cramping and lethargy.

Profile-Specific Questions & Answers
Will OMAD make a 230 lb man lose strength on bench press and squat?
No, provided you consume at least 180g protein and 200g+ carbohydrates in your evening window to fully restore intramuscular glycogen before your next training session.
What is the expected 12-week fat loss on this OMAD protocol?
A 230 lb male adhering to 2,200 kcal on OMAD can expect to lose 15 to 18 lbs of body fat over 12 weeks while maintaining muscle mass.
