Macro partitioning
Replacing saturated fat with unsaturated fats (PUFA/MUFA) significantly reduces cardiovascular disease risk and all-cause mortality, whereas replacing saturated fat with refined carbohydrates does not improve overall cardiovascular risk.
To lower your heart disease risk, swap high-saturated-fat foods (like fatty meats and full-fat dairy) for unsaturated fats found in plant oils (olive, canola), nuts, and seeds. Do not replace these fats with refined carbohydrates like white bread or sugar, as that fails to improve cardiovascular risk.
Replacing 5% of energy from saturated fats with equivalent energy from PUFA and MUFA was associated with estimated reductions in total mortality of 27%... and 13%... respectively... When dietary saturated fat is replaced with refined carbohydrates, LDL-C levels may decrease, but triglycerides and atherogenic small, dense LDL particles may increase while HDL-C decreases, thus not improving overall CVD risk
Why this rating
Based on large prospective cohort studies (Nurses' Health Study, Health Professionals Follow-up Study) and meta-analyses of RCTs, though some observational studies (PURE) show conflicting results.

- Medical Nutrition Therapy (MNT) provided by Registered Dietitian Nutritionists (RDNs) significantly improves cardiometabolic risk factors (LDL-C, TG, BMI, BP, HbA1c) and reduces medication costs in patients with dyslipidemia and cardiometabolic risk.Good
- Low-carbohydrate and very-low-carbohydrate (ketogenic) diets may offer short-term weight loss and triglyceride reduction for some individuals with obesity or diabetes, but long-term adherence is difficult and may increase LDL-C and mortality risk if animal-derived fats/proteins are prioritized over plant sources.Moderate

- 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
