Bio-Chemical Logistics
Fuel split, visceral incline, electrolyte loss, MPS bolus.
Four instruments for the logistics of fuel and fluid: macronutrient split by goal, waist-to-height cardiometabolic risk flag, electrolyte loss through sweat, and the per-meal protein bolus that maximises muscle protein synthesis.

- Fuel Partitioning — Daily macros by cut/maintain/bulk goal.
- Anabolic Trigger — Per-meal bolus that saturates MPS.
Featured tools
Fuel Partitioning · Macros
Daily protein, fat, and carb targets anchored to bodyweight and training goal. Protein-first, fat floor second, carbs fill.
Metabolic Incline · Waist-to-Height
Waist-to-height ratio — better predictor of cardiometabolic risk than BMI. "Keep your waist under half your height."
Ion Balance · Electrolyte Loss
Sodium, potassium, chloride, and magnesium lost through sweat over a training session. Replacement targets for endurance events.
Anabolic Trigger · MPS Bolus
Per-meal protein bolus that maximises muscle protein synthesis. 0.25-0.40 g/kg per feeding, 1.6-2.2 g/kg daily.

Frequently asked questions
› Why waist-to-height and not BMI? Troubleshooting
WHtR predicts visceral fat and cardiovascular risk across all populations (Ashwell 2012) — BMI fails for lean or muscular bodies.
› Is 2 g/kg protein dangerous? Trust & accuracy
No evidence of renal harm in healthy adults below 3.5 g/kg. The daily range 1.6–2.2 g/kg is the current evidence-based target.
