Macro partitioning
Adhering to current dietary guidelines (30-35% energy from fat, >50% from carbohydrates) is not associated with increased mortality or morbidity, whereas the PURE study's conclusion that high carbohydrate intake increases risk is invalid due to methodological flaws.
Do not change your macronutrient ratios based on headlines from single observational studies. Stick to established guidelines: moderate fat (30-35% of energy) and high carbohydrates (>50% of energy). Focus on improving diet quality by increasing fiber-rich foods and reducing added sugars and refined starches, as these factors are more critical for mortality risk than the fat-carb ratio itself.
Mit einer Ernährung, die entsprechend den Richtwerten der DGE einen moderaten Fettanteil von 30 – 35 En% und einem Kohlenhydratanteil von über 50 En% aufweist, ist in der PURE-Studie kein erhöhtes Risiko für Mortalität und Morbidität zu erkennen.
Why this rating
The paper is a viewpoint/critique of another study (PURE), not a primary clinical trial itself; it relies on methodological critique rather than new primary data.

- 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
