Solid science backs grapefruit’s slimming properties.

The July 30, 2012 Woman’s World is on newsstands now. It features a new and improved grapefruit diet inspired by real studies that prove grapefruit does melt fat!

Remember the old grapefruit diet from years back?

Well it turns out there may be some solid science behind the grapefruit/weight loss connection after all. Researchers at the famous Scripps Clinic in La Jolla, California found that eating half a grapefruit three times a day resulted in 800% more weight loss than those who skipped it completely.

How does it work? An antioxidant flavonoid found in grapefruit, naringenin, can increase insulin sensitivity which in turn triggers the liver to break down more fat. In fact, one report even called naringenin “rocket fuel” for fat-burning in the liver!

And that’s beyond grapefruit’s nutritional perks that include its offering of a low calorie source of vitamin C, a decent amount of potassium, and phytosterols that help to balance cholesterol levels.

Grapefruit has been one of my favorite fat flushing fruits for years. When you team it with other fat fighters like lean protein, essential fats and clean carbs, it’s the perfect formula for quick, safe weight loss.

Incorporate grapefruit into my turbo-charged Smoothie Shakedown program, and you’ll dramatically increase your fat-burning potential. The Smoothie Shakedown has helped thousands of Fat Flushers lose as much as 15-20 pounds in two weeks.

The grapefruit-containing Citrus Surprise smoothie is absolutely delicious.  Even for non-grapefruit lovers, when this super fat flushing fruit is paired with orange and a little spice, it becomes a favorite staple of the program. Check out the recipe here.

Note: Grapefruit may affect the metabolism of certain prescription meds. Please consult your physician. For those of you currently following my classic Fat Flush program, please note that the Grapefruit Diet in the article would be most appropriate for Phase 3. The “New Grapefruit Diet” was developed to introduce grapefruit’s slimming properties to a more mainstream audience. For those who are new to the Fat Flush program, pick up a copy of the classic The Fat Flush Plan for continued weight loss success.

As they say, “there’s a lot more juice in a grapefruit than meets the eye.”

    I thought I read somewhere in ALG’s books, that grapefruit might impair the liver’s ability to break down fat – confused…. I also think I read it in someone else’s writing?

    Mary Ann: The only caveat with grapefruit is that it can, in some cases, impair the absorption of certain medications – not the liver’s ability to break down fat.

    I was just wondering .. does it make a difference what type of grapefruit you use. By that I mean pink vs red vs white/yellow?

    Thanks 🙂

    Do you have to eat the bitter outside of the sections or just the juicy part?

      It’s best to eat the entire section, the white part is especially nutritious and full of fiber.

    The research showed that the whole fruit is superior for weight loss. The juice and capsules were not statistically signficant in the amount of weight loss shown.

    The Grapefruit does assist with weight loss!

    I began following “The Grapefruit Diet” which can be found online (the one referred to as the old diet in the above article) at the end of Feb 2012.
    To date I have lost a total of 21kg, and only need 3kg to reach my goal weight.
    I would definitely recommend it, it helps with cravings, you get Vit C, and the weight comes off like clock work each week at weigh in.

        with so many variations out there, it’s difficult to say which is the exact original protocol. All I know is that this protocol works wonderfully 🙂

    If you have high blood pressure, high cholesterol, or high trigylcerides, grapefruit has been found to reduce the effects of these conditions.So which is better yellow or red grapefruit? Well, in a study made where people who had a history of high cholesterol, those that ate the red grapefruit had the most effect in lower their blood pressure. The yellow also lowered blood pressure but not as much as the red grapefruit.:”
