The Claim

In overweight, sedentary adults with moderate dyslipidemia, 8 months of aerobic exercise reduces fasting insulin resistance (HOMA) by approximately 0.40 units, while resistance training does not produce a significant change in fasting insulin resistance (HOMA).

Cause and effect
1 study reviewed
In plain English

In overweight, sedentary adults with moderate dyslipidemia, 8 months of aerobic exercise lowers fasting insulin resistance by about 0.40 HOMA units, while resistance training does not lower it significantly.

See the scientific wording

In overweight, sedentary adults with moderate dyslipidemia, aerobic exercise improves fasting insulin resistance (HOMA) by approximately 0.40 units after 8 months, while resistance training shows no significant change, indicating aerobic activity is more effective for enhancing insulin sensitivity.

Why this might work

Aerobic exercise burns more energy than resistance training, which causes the body to break down fat stored in the liver and around internal organs. This reduces harmful fats inside liver cells and decreases signals that block insulin from working. As a result, the liver and muscles take up more glucose from the blood, and the body needs to produce less insulin to keep blood sugar stable.

  1. Study: Effects of aerobic vs. resistance training on visceral and liver fat stores, liver enzymes, and insulin resistance by HOMA in overweight adults from STRRIDE AT/RT.

    In overweight, inactive adults, walking or jogging for 8 months improved how well their bodies use insulin, lowering a key marker by 0.40 points. Lifting weights didn’t change this marker at all, showing aerobic exercise is better for this benefit.
