Protein Per Meal Target Calculator
Split your daily protein target across your meals and check it against the ~0.4 g/kg per-meal ceiling for muscle protein synthesis.
How it works
Daily protein = body weight × g/kg · Per meal = daily protein ÷ meals · MPS ceiling ≈ 0.4 g/kg per meal
Total daily protein drives most of the muscle and satiety benefit, but research on muscle protein synthesis suggests a single meal maximises the muscle-building response at roughly 0.4 g per kg of body weight — beyond that the surplus is still used, just less efficiently for building muscle. Dividing your daily target across several meals keeps each dose in the effective range. This tool shows the per-meal target and flags when a meal exceeds that ceiling.
Worked example
A 75 kg person targeting 1.6 g/kg needs 75 × 1.6 = 120 g of protein a day. Split over 4 meals that is 120 ÷ 4 = 30 g per meal — comfortably below the 75 × 0.4 = 30 g ceiling, so every meal is used efficiently.
Frequently asked questions
How much protein can the body use in one meal?
For muscle building, studies point to roughly 0.4 g per kg of body weight per meal (about 30–40 g for most adults) to maximise muscle protein synthesis. Protein above that is not wasted — it still counts toward daily needs and provides energy and amino acids — it just adds less muscle-building signal per meal.
How many protein meals should I aim for?
Three to five protein-containing meals or snacks spread through the day lets you hit a higher daily total while keeping each dose in the effective range. The exact number matters less than reaching your daily target.
Does the daily total or per-meal amount matter more?
Total daily protein is the primary driver of results. Per-meal distribution is a secondary refinement that helps once your daily intake is already on target.
