16:8 Intermittent Fasting Protocol & Macros (215 lb Male)
High-capacity time-restricted feeding plan for a 97.5 kg (215 lb) male lifter: 2,580 kcal, 195g protein, and 12-week recomposition curve.
A 215 lb male (22% body fat, 167.7 lb LBM) on a 16:8 intermittent fasting protocol requires 2450 kcal daily. Consume 195g protein split into three servings across an 8-hour window, pairing 270g carbohydrates peri-workout to restore glycogen while maximizing 16-hour fasting lipolysis.

Visual Intermittent Fasting Clock & Loss Curve

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 29% of your 193g 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.

| Timeline Stage | Time Window | Metabolic State | Nutritional Action |
|---|---|---|---|
| Fasting Phase | 8:00 PM - 12:00 PM | Lipolysis & Autophagy | Water, Unsweetened Coffee, Electrolytes |
| Break-Fast Meal | 12:00 PM (Noon) | mTORC1 Anabolism | 65g Protein + 100g low-GI carbs |
| Peri-Workout Shake | 4:30 PM | Rapid Protein Delivery | 40g Whey Isolate + 50g simple carbs |

Clinical Analysis: 16:8 Intermittent Fasting Protocol & Macros (215 lb Male)
At 215 lbs and 22% body fat, fasting enhances peripheral insulin sensitivity and reduces hepatic steatosis. Consuming 195g protein across an 8-hour window ensures steady nitrogen retention, while 16 hours of daily fasting lowers fasting blood glucose and resting insulin.
Key Execution Takeaways for This Profile
- Maintain an eating window between 12:00 PM and 8:00 PM.
- Hit 195g protein daily across 3 meals (65g protein per feeding).
- Consume 270g complex carbohydrates primarily around your resistance training sessions.

Profile-Specific Questions & Answers
How much fat can a 215 lb man lose in 12 weeks of 16:8?
Following this 2,580 kcal protocol with 4 weekly training sessions yields an expected loss of 12 to 15 lbs of body fat while maintaining or slightly increasing lean mass.
Can I drink sparkling mineral water while fasting?
Yes. Carbonated mineral water provides carbonation satiety, sodium, and magnesium with zero calories, making the fasting window easier to sustain.
