The Study

One year follow-up of overweight and obese hypertensive adults following intensive lifestyle therapy.

In simple terms

This study watched two groups of people who had been in a weight-loss program to see what happened a year later. It can tell us what was linked to staying at a lower weight, but it can't prove that the program caused the results because it didn't control everything during the year.
