The Claim

In overweight adults, habitual physical activity of at least 2.5 hours per week is associated with a 35% higher insulin sensitivity index compared to sedentary individuals, even after three days without exercise.

In plain English

Overweight adults who regularly exercise at least 2.5 hours per week have a 35% higher insulin sensitivity index than those who are sedentary, even if they haven't exercised in the past three days.

See the scientific wording

In overweight adults, habitual physical activity (≥2.5 hours per week) is associated with a 35% higher insulin sensitivity index (ISI) compared to sedentary peers, even after three days without exercise, suggesting that long-term exercise habits confer a persistent metabolic benefit independent of recent activity.

Why this might work

Regular exercise lowers harmful inflammation in fat tissue, which allows muscle and fat cells to respond better to insulin, pulling more sugar out of the blood and keeping blood sugar levels stable even after days without working out.

What the research says

1 study
  1. Study: Acute exercise ameliorates differences in insulin resistance between physically active and sedentary overweight adults

    People who exercise regularly have better blood sugar control even if they haven't worked out in days, because their bodies adapt over time. One workout can help sedentary people temporarily, but only regular exercise keeps the benefit going.
