Macro partitioning
Replacing saturated fat with refined carbohydrates provides no cardiovascular benefit, whereas substituting polyunsaturated fats (PUFA) for saturated fat or refined carbohydrates significantly reduces cardiovascular disease risk.
Stop focusing solely on cutting saturated fat. If you reduce saturated fat, make sure you replace it with polyunsaturated fats (like those in nuts, seeds, and vegetable oils) rather than refined carbs (like white bread or sugar). Replacing saturated fat with refined carbs offers no heart benefit, but replacing it with PUFA significantly lowers your risk of heart disease.
evidence from observational studies and randomized clinical trials demonstrates that replacing saturated fat with carbohydrates, specifically refined, has no benefit on CVD risk, while substituting polyunsaturated fats for either saturated fat or carbohydrate reduces risk.

- Mediterranean dietary patterns supplemented with extra-virgin olive oil or mixed nuts significantly reduce the risk of major cardiovascular events (myocardial infarction, stroke, or death) compared to a control diet reduced in dietary fat.Strong
- Trans fats from partially hydrogenated oils have no safe level of consumption and should be limited as much as possible due to their adverse effects on multiple cardiovascular risk factors.Strong

- 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
