16:8 Intermittent Fasting Protocol & Macros (170 lb Male)
Time-restricted feeding and calorie protocol for a 77.1 kg (170 lb) male: 2,250 kcal, 160g protein, and 1:00 PM to 9:00 PM feeding window.
A 170 lb male (17% body fat, 141.1 lb LBM) following 16:8 fasting (1:00 PM to 9:00 PM) should consume 2227 kcal daily. Distribute 160g protein across two substantial meals and a post-workout shake to stimulate muscle protein synthesis while mobilizing adipose stores during the 16-hour fast.

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 35% of your 162g 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 (170 lb Male)
A 170 lb male with 141.1 lbs of Lean Body Mass benefits significantly from 16:8 fasting. Research by Moro et al. (2016) shows that resistance-trained men following a 16:8 protocol maintain 100% of their strength and lean mass while experiencing enhanced systemic fat oxidation and reduced systemic inflammation.
Key Execution Takeaways for This Profile
- Maintain an eating window between 1:00 PM and 9:00 PM.
- Hit 160g protein daily (1.13g per lb LBM) divided into 3 feedings.
- Train in the afternoon around 4:00 PM to bracket your workout between two protein-rich meals.

Profile-Specific Questions & Answers
Will 16:8 fasting hurt my testosterone levels as a 170 lb man?
No. Human studies confirm that 16:8 fasting preserves free and total testosterone levels in resistance-trained men when total calories and dietary fats are maintained.
How much water should I drink during the fasting window?
Consume at least 1.5 to 2.0 liters of water during the 16-hour fast, adding a pinch of mineral salt to sustain blood volume and electrolytes.
