Macro partitioning
Animal-based proteins are consistently scored higher in quality than incomplete plant-based proteins, making them more effective for stimulating tissue anabolism in clinical or single-source meal contexts.
If you rely on plant proteins, you may need to eat more of them or combine different sources to get the same muscle-building benefit as animal proteins. Animal proteins (meat, dairy, eggs) are naturally more efficient at stimulating muscle growth.
GoodSupportsHIGH confidence
In practical terms, animal-based proteins are consistently scored higher in quality compared with incomplete proteins, regardless of the assessment method.
Why this rating
Supported by multiple quality scoring metrics (DIAAS, PDCAAS, BV) and consistent ranking across studies.

- Distributing protein intake evenly across meals (approx. 30 g/meal) maximizes 24-hour skeletal muscle protein synthesis compared to a skewed consumption pattern.Moderate
- Supplementing meals with 3-4 grams of leucine can improve or normalize muscle protein synthesis in aging muscle, acting as a trigger for the mTOR pathway.Moderate

- 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
