The Claim

In aging male mice, calorie restriction is associated with preserved skeletal muscle fiber structure and mitochondrial function, particularly when the dietary fat source is highly saturated, such as lard.

In plain English

When older male mice eat fewer calories, they tend to keep healthier muscles and energy-producing parts inside their cells—especially if their diet includes a lot of saturated fat like from lard.

What the research says

1 study

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

    The study found that old mice on a low-calorie diet with lard (which has lots of saturated fat) kept healthier muscles and energy-producing parts of their cells better than mice on low-calorie diets with other fats.
