Grapefruit- the great fruit?

Everybody remembers the Grapefruit Diet, it went something like this: eat only grapefruit and lose 20 lbs in as many days.

Thankfully that diet is gone but the myth of grapefruits as a fat burner is still around.

Is there any truth to it?

While it is not a good idea to rely solely on one food alone, grapefruits certainly have their merits. They contain plenty of Vitamin C, antioxidants and control insulin levels. Studies have shown that they can control the growth of cancer cells ( in vitro), help with DNA repair and fight Hepatitis C.

So that is a very impressive resume but what about my six pack? Patience, young Jedi...

Grapefruits contain naringin, a powerful anti-oxidant, that inhibits the activity of the enzyme CPY34A in the human liver. This enzyme is responsible for metabolizing caffeine, which is one of the most potent fat burners.

By consuming grapefruit, you are essentially expanding the half-life of your fat loss product (since pretty much all of them contain caffeine and/or green tea and your multiplying the effectiveness). Adding 1/2 of a grapefruit to your breakfast (no sugar!!) could really make a difference in your quest for abs.
