Macro partitioning
Replacing saturated fat with refined carbohydrates increases cardiovascular risk and obesity prevalence, whereas replacing it with unsaturated fats (MUFA/PUFA) improves lipid profiles and reduces risk.
Do not fear dietary fat, but be selective. Replace saturated fats (butter, fatty meats) with unsaturated fats (olive oil, nuts, fish) rather than refined carbohydrates (sugar, white bread). Avoid 'low-fat' products that often contain added sugars.

Replacing saturated fat with carbohydrate, particularly refined carbohydrate, does not confer a benefit. It is important not to conflate replacing saturated fat with carbohydrate rather than unsaturated fat, as some have done. (Alice H. Lichtenstein)
