Macro partitioning
Reducing dietary carbohydrate intake improves the atherogenic dyslipidemia profile (lowering triglycerides and small LDL particles) in individuals with metabolic syndrome or insulin resistance, whereas altering total or saturated fat content has little to no effect on this specific lipid phenotype.
If you have metabolic syndrome, insulin resistance, or high triglycerides, your primary dietary lever is carbohydrate reduction, not fat restriction. Lowering carbs significantly improves your lipid profile by reducing small, dense LDL particles and triglycerides. Changing the amount or type of fat in your diet (saturated vs. unsaturated) has minimal impact on this specific risk profile. Focus on reducing carbohydrates to improve your atherogenic dyslipidemia.
Extrapolating across all of these studies, the prevalence of pattern B increases with the amount of dietary carbohydrate and decreases with the amount of dietary fat... This observation suggests that dietary carbohydrates are the principal driver of atherogenic dyslipidemia... This finding indicates that dietary saturated fat content has little influence on the components of the atherogenic lipoprotein phenotype.
Why this rating
Based on multiple controlled crossover trials and prospective cohort studies cited, though long-term CVD outcomes are not yet established.
