Macro partitioning
The vast majority (approx. 92%) of daily protein intake in young adults comes from whole-food sources rather than supplemental protein isolates, regardless of training status.
You get almost all your protein (92%) from regular food, not supplements. This is typical for active young adults. You do not need to buy protein powder to meet your needs; focus on getting protein from meat, dairy, eggs, and plant sources.
A greater proportion (∼92%) of total protein was consumed as whole-foods compared with supplemental, irrespective of training status or sex (p < .001).
Why this rating

- 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
