Macro partitioning
The Lipid Hypothesis, which demonized saturated fats and promoted high-carbohydrate diets, is flawed and has contributed to the global pandemic of chronic metabolic diseases.
Re-evaluate your intake of saturated fats. The paper suggests that saturated fats are essential for health and that the high carbohydrate intake promoted by the Lipid Hypothesis may be contributing to metabolic diseases. Consider reducing carbohydrates and incorporating healthy saturated fats.

Today, along with added sugar, these carbohydrates account for between 65% and 75% of the proportion of this non-essential nutrient in the standard global diet, correlating with higher rates of obesity, diabetes, diabesity, and chronic diseases.
Why this rating
The paper is an essay citing secondary analyses and preprints rather than original primary clinical trials.

- 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
