16:8 Intermittent Fasting Protocol & Macros (185 lb Male)
Moro clinical protocol for an 83.9 kg (185 lb) male athlete: 2,380 kcal, 175g protein floor, and 12-week metabolic trajectory.
A 185 lb male (18% body fat, 151.7 lb LBM) executing 16:8 fasting requires 2359 kcal daily. Distribute 175g protein (2.55g/kg LBM) into three feedings between 12:00 PM and 8:00 PM, maintaining 3,400mg sodium to sustain gym strength while dropping 0.8 lb of fat per week.

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 32% of your 174g 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: 16:8 Intermittent Fasting Protocol & Macros (185 lb Male)
Carrying 151.7 lbs of Lean Body Mass, a 185 lb male thrives on the 16:8 time-restricted feeding paradigm. Consuming 175g protein within an 8-hour window provides 3 distinct pulses of essential amino acids, while 16 hours of daily fasting accelerates hepatic fatty acid oxidation.
Key Execution Takeaways for This Profile
- Confine daily energy intake to the 12:00 PM to 8:00 PM window.
- Lock protein at 175g daily across 3 feedings of at least 50g each.
- Consume 3,400mg sodium daily with mineral water to preserve workout pump and power.

Profile-Specific Questions & Answers
Can I gain muscle on 16:8 fasting at 185 lbs?
Yes. As long as total daily calories equal or slightly exceed maintenance and protein reaches 1.6g–2.2g/kg, muscle hypertrophy is identical to traditional eating schedules.
Will branched-chain amino acids (BCAAs) break my fast?
Yes. BCAAs trigger insulin release and activate mTOR, stopping the autophagic benefits of fasting. Save amino acids for your feeding window.
