Macro partitioning
Older adults require higher protein intake (1.4-1.6 g/kg/day) than the standard RDA (0.8 g/kg/day) to maintain muscle mass and bone health.
Increase your daily protein intake to 1.4-1.6 grams per kilogram of body weight to help preserve muscle and bone as you age.
ModerateSupportsMEDIUM confidence
several nitrogen balance studies conducted in individuals ranging in age from 56-80 years, have suggested that higher amounts of protein intake (1.4-1.6 g/kg/day) would be better for older adults.
Why this rating
Based on nitrogen balance studies and observational data cited in a review.

- 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
