Macro partitioning
Moderate carbohydrate intake (50-60% of energy) is associated with the lowest all-cause mortality risk, forming a U-shaped relationship where both very low (<40%) and very high (>70%) intakes increase mortality risk.
Aim for 50-60% of your calories from carbohydrates for optimal longevity. Both very low and very high carbohydrate intakes are associated with higher mortality risks.
GoodSupportsHIGH confidence
The optimal range of carbohydrate intake was depicted by a U-shaped relationship between carbohydrate intake and mortality, with 50%–60% of energy from carbohydrates having the lowest mortality risk.
Why this rating
Based on large multinational cohort studies (PURE, ARIC) and meta-analyses.

- Low-carbohydrate diets (<40% energy) are at least as effective as low-fat diets for short-term weight loss and improve triglyceride and HDL cholesterol profiles, but they increase total and LDL cholesterol levels.Good
- In Korean populations, high carbohydrate intake (50-80% of energy) is associated with an increased risk of metabolic syndrome, elevated triglycerides, and lower HDL cholesterol, but a reduced risk of elevated total and LDL cholesterol.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
