This citrus fruit increased fat loss after 12 weeks

Today’s article is just a nice little quick tip that’s easy to add to your diet here and there for enhanced fat loss benefits…

A few months ago, I came across a study published in 2006 in the Journal of Medicinal Food, titled “The effects of grapefruit on weight and insulin resistance“…

The study measured results after 12 weeks of 91 obese patients broken down into a placebo group, a group that received a half of a fresh grapefruit before each meal (3x a day), a group that received an 8 oz glass of grapefruit juice before each meal, and a group that received a grapefruit capsule before each meal.

The results were very interesting, as you can see below…

It turned out that grapefruit before a meal DID in fact increase fat loss, with the FRESH grapefruit group losing the MOST weight, although even the grapefruit juice group and the grapefruit capsule group lost more than the placebo group.

The study concluded, “There was also a significant reduction in 2-hour post-glucose insulin level in the grapefruit group compared with placebo. Half of a fresh grapefruit eaten before meals was associated with significant weight loss. Insulin resistance was improved with fresh grapefruit.

It’s interesting to note that the fresh grapefruit improved insulin sensitivity, thereby helping to control insulin and blood sugar levels, despite the carbohydrates contained in the grapefruit.  This is similar to the results I showed you in this article where pre-meal lemon juice was also shown to control the blood sugar response from a meal… which is yet another example of a citrus fruit improving insulin sensitivity and blood sugar control.

I would also venture a guess that a similar result would be seen in fresh squeezed lime juice, but I have not seen any studies on this as of yet.

Speaking of unique little “daily rituals” that can help you lose weight quicker and easier, check this out…

If you haven’t tried this yet below, you’re going to want to add this to your morning routine. Drinking 1 cup of this delicious hot beverage described below in the morning sets you up to burn more fat than 45 exhausting minutes on the treadmill…

In fact, some folks are losing up to 23 lbs of fat in just 21 days by drinking it every morning:

    Did you guys even check the effects of grapefruit on other diabetic drugs? People with Diabetes tend to have a whole list of ailments attributed to it. High blood pressure, high cholesteral etc. The drugs that we take for these issues react with Grapefruit and from what I hear not in a good way! I love, love love grapefruit,but, I had to give it up years ago when I started taking Metformin. Where are these issues in your article? You are recommending a fruit that could potentially react with medications being taken by a diabetic. I hope I am not just blowing smoke, but you need to check those interactions before you can recommend anything.

    • Same here no more grapefruit and loved it

    • Why don’t you seek cure instead of taking drugs?

    • When I am told that my pharma medication contraindicates with broccoli, grapefruit etc, I will review my pharma medication.

      I to Love grapefruit and had to stop taking it because of Januvia and Invokana that I take for my diabetes. I used to be on Metformin until I lost the feelings in my hands and feet and thoses pills were history right quick. The Januvia 100mg have worked just fine ever since.
      Grapefruit do work but< interfere with certain drugs.

  2. Good

  3. I take a medicine that says positivelyly do not eat or drink grapefruit yet that is not mentioned in the advertisement???

  4. Sounds like the “ol grapefruit diet” from years ago, when I was MUCH younger. I’m sorry to hear the negative effect it has for many. It is very good that you are knowledgeable as to the pros and cons of how it could affect you, esp since it’s not given mention here. Health and wellness to everyone. Always important to know what affects your body personally.

  5. I, too, am on medication that does not ‘allow’ grapefruit…………and I LOVE and miss it. Any advice/suggestions about THAT! I have OFTEN thought of trying it to see what the effects would be, but I’m aftaid. (I was told by one pharmacist that if I take the medication in the morning, I could have the grapefruit later in the day????)

    I would caution drinking grapefruit with every meal, as I take Simvastatin for cholesterol, and the grapefruit is known to suppress absorption of the Statin drugs. In fact the Statin will just sit there doing nothing, and will pile up the doses every day until you stop drinking the Grapefruit. Then… all of the Statin sitting there, Lord knows how much is just waiting in a bulk, and then it all gets released and absorbed at once. This is a very “Bad” thing for you liver and Kidneys to get that Large dose all at once.

    • I have had grapefruit for breakfast for years now.
      I also take statin pills for cholestrol but when I read “no grapefruit” on the pills I asked my Doctor and
      he said that as long as its at least 8hrs apart there is no problem as the grapefruit has been absorbed into the body by then.
      So I have always taken the Stain pill with my tea time meal. Never had a problem.
      Cheers, Allen

    GRAPEFRUIT is the Only Citrus Fruit that counteracts with certain drugs. ALL Other Citrus do not!!!.

  8. Personally do not have diabetes, or any lifestyle problems but wanted to lose a few kilos. Have achieved that and love enjoying my grapefruit every single day.
    Bringing down blood sugar and insulin resistance can only be a good thing for anyone; an extremely important achievement and of vital importance!!
    Happen to know that Metformin and statins are now no longer considered to be acceptable medication.
    Obesity is so much linked to Diabetes, high blood pressure, heart problems etc; that if someone who really needs to lose weight should consider this as the first step…

  9. Personally do not have diabetes, or any lifestyle problems but wanted to lose a few kilos. Have achieved that and love enjoying my grapefruit every single day; sometimes sprinkling a little ground cinnamon over it too.
    Bringing down blood sugar and insulin resistance can only be a good thing for anyone; an extremely important achievement and of vital importance!!
    Happen to know that Metformin and statins are now no longer considered to be acceptable medication!!!
    Obesity is so much linked to Diabetes, high blood pressure, heart problems etc; that if someone who really needs to lose a huge amount of weight they would see how important it is do so for a MUCH BETTER LIFE???

  10. Personally do not have diabetes, or any lifestyle problems but wanted to lose a few kilos. Have achieved that and love enjoying my ruby grapefruit which tastes so good since it is naturally sweet; sometimes sprinkling a little ground cinnamon over it too.
    Bringing down blood sugar and insulin resistance can only be a good thing for anyone; an extremely important achievement and of vital importance!!
    Happen to know that Metformin and statins are now no longer considered to be acceptable medication for various medical reasons.
    OBESITY is so much linked to Diabetes, high blood pressure, heart problems etc; that if someone who really needs to loses a huge amount of weight they would see how important it is do do so for a FAR BETTER QUALITY OF LIFE?????????????? (Many thanks Dr. Geary for this “ruby grapefruit tip” …)

  11. We have a variety of types of grapefruit. The pink variety is recommended as being particularly good for you. Are you aware of any studies looking at the effect of the different grapefruits?

  12. Multiple articles have been published in medical journals (e.g. double-blind refereed studies) that show that grapefruit interacts with important enzymes that are needed to break down medication. This is so well known that even consumer health and medical websites like drugs.com devote webpages to the issue. I am continually concerned with the often implicit message in thenutritionwatchdog articles that “getting healthy” is all in control of the individual and when achieved our medications will go by the wayside; given that certain cardiac, hypertension, and metabolic conditions run in families do to genetic patterns, and medications are essential for one’s well being. thenutritionwatchdog needs to elevate it’s awareness and do it’s due diligence to include information on medication interactions; failing to do so de-legitimizing the organization.

  13. I also love Grapefruit, but due to certain medications I have to take, have been told not to eat Grapefruit – wonder whether Allen Gilton’s comments could also apply to me?! Hope so!

  14. I assume all these comments are referring to Type 2 Diabetes? It would be helpful if this was clearly stated.
    Is there any advice about grapefruit and Type 1 Diabetes?
