Protein Distribution and Muscle Protein Synthesis

Research suggests that muscle protein synthesis (MPS) — the process of building new muscle tissue — is maximized at approximately 0.4g of protein per kg body weight per meal, with some studies suggesting the upper limit may be closer to 0.55g/kg. Spreading protein intake across 3–5 meals throughout the day tends to produce greater MPS stimulation over 24 hours compared to consuming the same total in fewer, larger meals.

Frequently Asked Questions

How much protein can the body absorb per meal?
+
The body can absorb protein from any single meal — there is no hard cap. However, the rate of muscle protein synthesis appears to plateau at approximately 0.4–0.55g protein per kg body weight per meal. Additional protein beyond this in a single sitting is used for energy or other metabolic processes rather than additional MPS stimulation.
Is there a limit to how much protein the body can use per meal?
+
Research suggests muscle protein synthesis is maximally stimulated by approximately 20–40g of high-quality protein per meal, with larger individuals at the higher end. However, protein consumed beyond this threshold is not wasted — it is used for other metabolic functions, converted to energy, or stored. A 2023 study suggested that consuming up to 100g of protein in a single meal may result in slower but extended muscle protein synthesis, challenging the older 'ceiling' model.
What is the best protein source to eat after training?
+
High-leucine, rapidly digested proteins are most effective at stimulating muscle protein synthesis post-exercise. Whey protein isolate, eggs, chicken breast, and tuna are all excellent options due to their high leucine content and fast digestion speed. For plant-based athletes, soy protein has the most complete amino acid profile and closest leucine content to animal sources.
How many protein meals should I eat per day?
+
Research generally supports 3–5 protein-containing meals per day for optimal MPS over 24 hours. Intermittent fasting approaches that compress eating windows do not necessarily impair total MPS if total daily protein targets are met.
