Reducing saturated fat intake primarily lowers LDL cholesterol, a key driver of atherosclerosis. By mitigating the buildup of arterial plaques, this dietary strategy reduces the risk of cardiovascular events like heart attacks and strokes, which are major contributors to mortality and morbidity in aging.

Protocol
- Limit saturated fat intake to less than 10% of total daily calories, with some protocols suggesting below 7% for maximal cardiovascular benefit.
Flags
- Replacing saturated fats with refined carbohydrates may negate or reverse potential benefits.
- Focus should be on replacement with unsaturated fats (MUFAs, PUFAs), not just reduction.
- Extreme restriction is unnecessary and may impact hormone production or fat-soluble vitamin absorption.
