Macro partitioning
Dietary fiber is a more reliable predictor of satiety and metabolic health than Glycemic Index, as low-GI diets often derive their benefits from higher fiber content rather than the glycemic response itself.
Prioritize fiber over Glycemic Index. If you are choosing between carbohydrate sources, pick the one with more fiber (vegetables, legumes, whole grains) rather than worrying about whether it spikes blood sugar quickly. High-fiber foods naturally promote fullness and better metabolic markers, making the GI calculation unnecessary for most people.
Other measures of dietary quality, such as fiber or whole grains may be more likely to predict health outcomes.
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
