Being fit helps keep arteries young—even if you're overweight

Even if you're a little chubby, if you can run fast, your artery walls are thinner and healthier. But if your blood has too much fat (triglycerides), your artery walls get thicker.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

High levels of physical fitness do not confer complete immunity against the development of coronary atherosclerosis.
Young adults who can run 3000 meters faster tend to have thinner artery walls in their necks, which is a sign of less early artery damage, even if they’re overweight or have other risk factors.
Among young, active adults, high levels of triglycerides (a type of fat in the blood) are the only blood marker that consistently links to thicker artery walls — more than cholesterol, blood sugar, or belly fat.
Whether young adults are normal weight or overweight, better fitness is just as strongly linked to thinner artery walls — meaning being fit helps your arteries even if you carry extra weight.
Even though belly fat is often blamed for heart problems, in young, active adults, it doesn’t seem to directly affect artery thickness — fitness and triglycerides matter more.
