Macro partitioning
Evenly distributing protein intake across 3-4 meals (approx. 0.3-0.4 g/kg per meal) is a pragmatic strategy to maximize daily muscle protein synthesis, particularly for older adults or during energy restriction, though total daily protein remains the primary driver.
Aim to spread your protein intake across 3-4 meals, targeting roughly 30 grams per meal. This is especially important if you are older or trying to lose weight, as your body becomes less efficient at using protein for muscle building. If you currently eat most of your protein at dinner, try moving a portion to breakfast and lunch.
Evenly distributing protein intake throughout the day is a pragmatic strategy to enhance skeletal muscle anabolism at each meal - especially when combined with RT. However, with increasing daily protein intakes, the benefits of an even vs. skewed protein consumption pattern ostensibly become less important.
Why this rating
Evidence is mixed; some studies show benefit, others show no difference, likely due to varying total protein intakes.

- Resistance exercise sensitizes skeletal muscle to amino acids for 24-48 hours, allowing a moderate protein dose (~20g) to maximally stimulate muscle protein synthesis (MPS) without requiring higher doses.Good
- Leucine acts as the primary trigger for muscle protein synthesis by activating the mTORC1 pathway, and increasing leucine content in lower-quality proteins can restore the anabolic response in older adults.Good

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
