The Claim

Resistance training alone, independent of protein intake, significantly reduces low-density lipoprotein cholesterol and total cholesterol levels in healthy older men.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

In healthy older men, doing resistance training without changing protein intake lowers LDL cholesterol and total cholesterol levels.

See the scientific wording

Resistance training alone, regardless of protein intake level, significantly reduces low-density lipoprotein and total cholesterol in healthy older men, indicating that exercise is the primary driver of lipid profile improvement in this population.

Why this might work

When older men lift weights regularly, their muscles grow larger and use more energy. This forces the liver to pull more bad cholesterol out of the blood to fuel the muscles and to make new cell membranes. The liver also stops making as much cholesterol because the body has enough from the blood, so overall cholesterol levels drop.

  1. Study: Effects of 8 weeks of resistance training in combination with a high protein diet on body composition, muscular performance, and markers of liver and kidney function in untrained older ex-military men

    Both groups of older men lifted weights, one ate more protein and one ate less — but both saw their bad cholesterol drop the same amount. That means the weightlifting itself lowered cholesterol, not the protein they ate.
