Yo-Yo Dieting May Pose Serious Risks For Heart Patients

Over a period averaging 4.7 years, study participants who had the greatest fluctuations in weight — about 8.6 pounds — had double the risk of a heart attack, stroke or death, when compared with those who experienced weight fluctuations of less than 2 pounds.

People with heart disease should keep their weight down, but it can be hard to lose weight and keep it off. Now a study shows big fluctuations may increase the risk of heart attack and stroke.
