Macro partitioning
Resistance-trained young adults consume significantly higher absolute and relative protein intakes (averaging 1.6–2.0 g/kg/day) than recreationally active peers, with animal-derived proteins comprising the majority (approx. 68-72%) of total intake.
If you lift weights regularly, you are likely eating more protein than the average person, averaging 1.6 to 2.0 grams per kilogram of body weight. Most of this comes from animal sources. This is normal and expected for your activity level. You do not need to worry about the RDA of 0.8 g/kg, as your intake is already well above that threshold.
Absolute (p < .001) and relative (to body mass [BM]; p < .001) protein intakes were greater in TRA (males, 159 ± 54 g/day or 1.6 ± 0.7 g·kg−1 BM·day−1; females, 105 ± 40 g/day or 2.0 ± 0.6 g·kg−1 BM·day−1; p < .001) than REC (males, 103 ± 37 g/day or 1.3 ± 0.5 g·kg−1 BM·day−1; females, 85 ± 23 g/day or 1.3 ± 0.4 g·kg−1 BM·day−1; p < .001)... A greater proportion of total protein was consumed from animal compared with nonanimal in TRA (68% vs. 32%, respectively; p < .001) and REC (64% vs. 36%, respectively; p < .001)
Why this rating
Cross-sectional analysis of a large, well-characterized cohort (n=104) using weighed food diaries, though causality cannot be established.

- 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
