You might lose weight with the high-fat Atkins Diet of eggs, meat and cheese - but it could put you at risk of heart disease by raising your cholesterol and damaging your blood vessels, according to a new study.

Researchers at the University of Maryland put 26 people on three diets - the high-fat Atkins and the low-fat South Beach and Ornish diets, according to an article in the New York Post.

Eighteen people finished the study, which required each of them to follow one of the diets for a month. All along, doctors checked their cholesterol and the condition of their arteries.

The Atkins Diet raised the study subjects' bad cholesterol by an average of 16 points, and brought on symptoms of hardening of the arteries, a precursor to strokes or heart attacks.

The subjects had better lab tests on the other two diets. The Ornish Diet lowered their bad cholesterol by 25 points, while the South Beach Diet lowered it by 10 points. The conditions of their arteries also improved on both diets.
