I have not had much up here about intermittent fasting / IF for a while. (For those interested I like both Brad Pilon and Martin Berkhan's approaches). Anyway, this report indicates that fasting prompts an enzyme that turns off the body's generation of fats and cholesterol.
As I said I don't think dietary cholesterol is a problem, and I'd disagree with some of the stuff in the article about a high fat diet, but this is an interesting finding for those who practice intermittent fasting.
When Food Intake Stops, Enzyme Turns Off Production of Fats, Cholesterol
"This study is significant because it explains the signals that tell the body to burn fat in response to fasting or dieting," says David Sinclair, PhD, a professor of Pathology at Harvard Medical School (HMS) who helped discover the genes that code for sirtuins but was not involved with this MGH-led study. "This improved understanding could help treat and prevent metabolic diseases such as atherosclerosis and type 2 diabetes."
