The Influence of Dietary Fat Source on Life Span in Calorie Restricted Mice.

Cohort Study

Animal

2015 Oct

The study found that mice on a low-calorie diet lived longer when they ate more saturated fats (like lard) instead of unsaturated fats (like in fish or soybean oil), which supports the idea that saturated fats help extend life in calorie-restricted conditions.

The Impact of Aging, Calorie Restriction and Dietary Fat on Autophagy Markers and Mitochondrial Ultrastructure and Dynamics in Mouse Skeletal Muscle.

Cross-Sectional Study

Animal

2019 May 16

Mice on a low-calorie diet lived longer when their fat came from lard (like bacon fat) instead of vegetable or fish oils, because lard has more 'saturated' fat. This matches the idea that more saturated fat can help extend life when eating less.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

In male mice eating 40% fewer calories, the type of fat they eat matters — mice live longer on more saturated fats like lard than on unsaturated fats like soybean or fish oil.

Fats that are more saturated, like those in butter or olive oil, don’t break down as easily in your body, and that might help you live longer if you're eating fewer calories.

Eating more saturated fat might shorten your life — studies show people aged 55 to 74 who eat more of it have a higher chance of dying earlier, so cutting back could help you live longer.
