(CLS Prevention Active · Zero Shift)Daily Protein & Creatine Monohydrate Intake Guide
The Protein & Creatine Intake Calculator determines optimal daily macronutrient targets based on international sports nutrition frameworks (ISSN, ACSM).
By processing body weight, body fat %, Lean Body Mass (LBM), and specific physical objectives (Hypertrophy, Fat Loss, Maintenance, or Endurance), it calculates precise daily protein needs, per-meal distribution schedules, and creatine dosages.
To ensure maximal muscle protein synthesis (MPS), the tool incorporates the Leucine Threshold (2.5g to 3.0g per meal) across 3 to 5 evenly spaced feedings alongside clinically validated creatine dosing regimens.
Muscle Protein Synthesis & Phosphocreatine Saturation
The intracellular mechanisms governing hyperaminoacidemia, mTOR activation, and cellular hydration.
Distributing 30g to 45g of protein per meal satisfies the 3.0g leucine threshold, repeatedly triggering the mTOR pathway.
👉 The lifter targets 150g protein daily divided into four 37.5g meals with 5g daily creatine.
Target Protein & Creatine Guidelines (ISSN / ACSM)
Evidence-based dietary recommendations by athletic objective
| Fitness Goal | Daily Protein (g/kg Weight) | LBM Basis | Physiological Function | Per-Meal Target (4 Meals) | Creatine Protocol |
|---|---|---|---|---|---|
| Hypertrophy / Muscle Gain | 1.6 - 2.2 g/kg | 2.0 - 2.4 g/kg | Maximizes protein synthesis (MPS) | 35 - 45 g/meal | 5 g/day recommended |
| Fat Loss / Cutting | 2.0 - 2.6 g/kg | 2.3 - 2.8 g/kg | Shields lean tissue during deficit | 35 - 50 g/meal | 3 - 5 g/day |
| Maintenance / Health | 1.2 - 1.6 g/kg | 1.5 - 1.9 g/kg | Sustains nitrogen balance | 25 - 35 g/meal | 3 g/day optional |
| Endurance Athletics | 1.2 - 1.5 g/kg | 1.4 - 1.8 g/kg | Compensates for amino acid oxidation | 25 - 30 g/meal | 3 g/day |
| Sedentary Baseline (RDA) | 0.8 - 1.0 g/kg | 1.0 - 1.2 g/kg | Minimum clinical threshold | 20 - 25 g/meal | Not required |
| Elderly Sarcopenia | 1.2 - 1.5 g/kg | 1.6 - 2.0 g/kg | Overcomes anabolic resistance | 35 - 40 g/meal | 3 - 5 g/day |

(CLS Prevention Active · Zero Shift)How to Use
11. Input Weight and Body Fat %
Enter body weight in kg or lbs and optional body fat % to unlock Lean Body Mass (LBM) calculations.
22. Choose Athletic Objective
Select Hypertrophy (2.0g/kg), Fat Loss Cutting (2.2g/kg), Maintenance (1.4g/kg), or Endurance.
33. Set Meal Frequency and Creatine Strategy
Choose daily meal frequency (3 to 5 meals) and creatine approach (daily flat 3-5g vs 5-day loading).
44. Review Targets and Food Offsets
Examine total daily protein, per-meal targets, creatine dose, hydration targets, and real-food equivalents.
Practical Meal Planning Examples
Lean bulking, contest prep deficit, and senior muscle preservation
An 80 kg male consuming 160 g of protein daily divided into 4 meals of 40 g with 5 g creatine monohydrate.
A 65 kg competitor consuming 143 g (2.2 g/kg) to shield lean tissue during an aggressive 500 kcal deficit.
A 70-year-old maintaining 1.3 g/kg protein intake with high-leucine proteins to stimulate aging muscle receptors.
💡 Supplementation & Nutrition Best Practices
Evenly spacing feedings allows intracellular leucine to reset, enabling repeated surges in muscle protein synthesis.
Creatine monohydrate is 100% bioavailable and backed by hundreds of studies; expensive designer forms offer no superior efficacy.
Creatine draws water into muscle cells; drink at least 500 mL of additional water daily to support hydration.
⚠️ Common Pitfalls & Mistakes to Avoid
Frequently Asked Questions (FAQ)
Expert answers to the most frequently asked questions and edge cases.
A loading phase saturates intramuscular phosphocreatine stores within 5 to 7 days. However, taking a flat 3g to 5g daily reaches the exact same saturation within 28 days without gastrointestinal upset.
