via jypsygen at FlickrEating grapefruit has an effect similar to eating an Atkins diet, without the negtive side effects, say researchers at the Hebrew University of Jerusalem and Massachusetts General Hospital.

Researchers believe that naringenin, an antioxident derived from the bitter flavor of grapefruits and other citrus fruits may cause the liver to break down fat while increasing insulin sensitivity. If so, naringenin mimics a body process associated with long periods of fasting.

The results also mean that naringenin mimics the actions of several diabetes drugs, such as the lipid-lowering Fenofibrate and the anti-diabetic Rosiglitazone, offering the advantages of both.

If the results of this study extend to human patients, this dietary supplement could become a staple in the treatment of hyperlipidemia, type-2 diabetes, and perhaps metabolic syndrome. The report appears in this week issue of the online journal PLoS ONE. via Science Daily

Following a meal, the blood is flushed with sugars that activate LXRα, causing the liver to create fatty acids for long-term storage. During fasting, the process is reversed;
