The Claim

In obese young men with metabolic syndrome, a 12-week intervention combining caloric restriction with aerobic and resistance exercise significantly improves blood pressure and does not significantly improve HDL cholesterol.

In plain English

In obese young men with metabolic syndrome, a 12-week program of reduced calorie intake combined with aerobic and resistance exercise lowers blood pressure but does not raise HDL cholesterol levels.

See the scientific wording

In obese young men with metabolic syndrome, a 12-week intervention combining caloric restriction with aerobic and resistance exercise significantly improves blood pressure, but does not significantly improve HDL cholesterol, indicating that lipid profile improvements are selective and not uniformly enhanced by exercise.

Why this might work

When a person eats less and exercises, their belly fat shrinks, which reduces the amount of fat entering the liver. This lowers the production of harmful blood fats and allows blood vessels to relax more easily by releasing more nitric oxide. As a result, blood pressure drops. The same changes do not affect the good cholesterol because the body's system for making and removing it stays unchanged.

  1. Study: Effects of diet versus diet plus aerobic and resistance exercise on metabolic syndrome in obese young men

    The study found that adding exercise to a diet helped lower blood pressure in young obese men with metabolic syndrome, which matches the claim. It didn't measure 'good' cholesterol (HDL), so we can't say if it went up or down — but since it didn't say it improved, it doesn't contradict the claim that HDL didn't change.
