Macro partitioning
High-protein diets, particularly those with a high Glycemic Index, can increase LDL cholesterol levels, negating cardiovascular benefits despite potential fat loss.
Be cautious with high-protein diets that also rely on high-GI carbohydrates (like white rice/pasta with meat). This combination may raise your LDL cholesterol. Opt for high-protein diets paired with low-GI carbohydrates to avoid this risk.
