Optimal Meal Distribution (Muscle Protein Synthesis)

Spreading protein across 3 to 5 meals (with ~25–45g per feeding) maximizes the leucine threshold to stimulate muscle protein synthesis (MPS) throughout the day:

3 Meals / Day

0 g

per meal

4 Meals / Day (Recommended)

0 g

5 Meals / Day

0 g

Quick Food Equivalents (To hit ~30g Protein):

Chicken Breast ~100g cooked (31g protein)

Whole Eggs / Whites 4-5 whole eggs or 8 whites (30g protein)

Greek Yogurt / Skyr ~300g non-fat (30g protein)

Whey / Plant Isolate 1 rounded scoop (24–28g protein)

Evidence Baseline: Calculations follow the British Journal of Sports Medicine systematic meta-analysis (Morton et al., 2018) showing protein intakes beyond 1.62 g/kg (0.73 g/lb) offer plateauing gains for natural lifters in energy balance, while hypocaloric fat-loss phases benefit from higher intakes (up to 2.4 g/kg) to buffer against muscle breakdown.

How Much Protein Do You Really Need?

Protein is the primary building block of skeletal muscle tissue and is vital for cellular repair, enzymatic functions, and hormone synthesis. Daily requirements vary significantly depending on physical activity and energy balance:

Sedentary Adults: The Recommended Dietary Allowance (RDA) baseline of 0.8 g/kg prevents deficiency in healthy non-exercising individuals.
Endurance Athletes: Runners, cyclists, and swimmers typically require 1.2 to 1.6 g/kg to support glycogen resynthesis and repair exercise-induced muscle damage.
Resistance Training & Muscle Hypertrophy: Scientific consensus recommends 1.6 to 2.2 g/kg (approx. 0.73 to 1.0 g/lb) to maximize muscle protein synthesis.
Fat Loss / Caloric Deficit: High protein intakes of 2.0 to 2.4+ g/kg are effective for sparing lean muscle mass and boosting satiety while eating in an energy deficit.
