Regular readers may remember that I reported here on earlier studies about some benefits from intermittent fasting. But a study reported yesterday shows that fasting also lowers the risk of heart disease and diabetes and increases the good HDL cholesterol and reduces triglycerides, weight, and blood glucose levels. It also increases the bad LDL cholesterol.
Research cardiologists at the Intermountain Medical Center Heart Institute in Murray, Utah, reported these finds at the annual scientific sessions of the American College of Cardiology in New Orleans. Tomorrow’s issue of the Journal of the American College of Cardiology will print the results of this study led by Dr. Benjamin D. Horne, Intermountain’s director of cardiovascular and genetic epidemiology.
LDL went up by 14 percent and HDL by 6 percent. But the increase in cholesterol from fasting is probably not a bad thing, as Dr. Horne explains.
“Fasting causes hunger or stress,” he pointed out. “In response, the body releases more cholesterol, allowing it to utilize fat as a source of fuel, instead of glucose. This decreases the number of fat cells in the body. This is important because the fewer fat cells a body has, the less likely it will experience insulin resistance or diabetes.”
Dr. Horne’s team conducted two fasting studies. One included more than 200 people. Another included 30 people who only had water for 24 hours and then studied for another day. During this additional 24-hour period the researchers subjected the subjects to blood tests and other physical measurements.
Now I have the incentive to get back to intermittent fasting. Just as soon as I finish the fish in my fridge.
