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

Cohort Study

Animal

2015 Oct

The study found that while eating less helped mice live longer, the type of fat in their diet still mattered—mice on a lard-based low-PUFA diet lived the longest, so the benefit of eating less depends on what kind of fat they eat.

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.

Mice that eat fewer calories live longer, and among those on a low-calorie diet, the ones eating mostly lard seem to live the longest.
