Atherosclerosis is a progressive condition where the arteries thicken with fatty deposits, increasing the risk of heart attacks and strokes.
A study in the journal Circulation followed 140 overweight people for two years. Their neck arteries were scanned before and then after the dieting.
The study suggests the artery thinning could be related to falling blood pressure caused by the change in diet. It adds weight to growing evidence suggesting hardening of the arteries is a disease that can be fixed.
