Results of a six-month study at Johns Hopkins University were presented March 13 at an American Heart Association scientific meeting in San Diego:
"Overall, there was an improvement in vascular health that was related to how much abdominal fat was lost,"http://www.marketwatch.com/story/new-st ... 2012-03-14
"The more belly fat the participants lost, the better their arteries were able to expand when needed, allowing more blood to flow more freely." http://timesofindia.indiatimes.com/life ... 262921.cms
Insulin is obviously involved; in my opinion, this study implicates insulin with artery health.
