Macro partitioning
Low-carbohydrate/high-protein diets improve cardiovascular risk markers (HDL, Triglycerides, Systolic BP) more effectively than low-fat diets, despite potentially increasing LDL and Total Cholesterol.
When switching to a low-carb diet, monitor your lipids. You may see an increase in LDL and Total Cholesterol, but you will likely see a beneficial increase in HDL ('good') cholesterol, a drop in Triglycerides, and a slight drop in blood pressure. These changes often offset the LDL increase, resulting in a net positive or neutral cardiovascular risk profile compared to low-fat diets.
There were significant differences between the groups for weight, high-density lipoprotein cholesterol, triacylglycerols and systolic blood pressure, favouring the low-carbohydrate diet.
Why this rating
Consistent findings across multiple lipid parameters in the meta-analysis, though heterogeneity exists.
