The Grapefruit Diet is a weight loss program that encourages men and women to consume grapefruit. This fruit is claimed to assist with fat burning and increasing the user’s metabolism. The official website states that users can drop up to 10 pounds over a 12-day period while strictly following the diet this long. The key is to consume one half of a grapefruit prior to each meal. However, dieters are not supposed to consume more than a total of 800 calories each day during the 12 days.

The key active component found in the Grapefruit Diet is a “fat-burning enzyme,” which is naturally a part of grapefruit. Since the fruit is eaten before each meal, it assists the user with burning fat and calories from the meal more rapidly. Grapefruit is a fat-free food and it doesn’t contain much sodium; therefore water retention is minimized as well. Other healthy components of the Grapefruit Diet are Vitamin C, Beta-carotene (reduces cholesterol), antioxidants and fiber. However, there are a few drawbacks mentioned on the Grapefruit Diet official website such as low protein overall, possible dizziness due to the change/lack of nutrition and an overall lack of vitamins and minerals. There are no dietary supplements involved with the Grapefruit Diet. There is a diet review offered on the official website discussing when and how the Grapefruit Diet began. Testimonials are offered on the website in a discussion forum that centers on the Grapefruit Diet.

  • Grapefruits are healthy overall and contains Vitamin C, Beta-carotene and antioxidants.
  • Though they can be difficult to follow sometimes, the instructions for this diet are very clear.
  • The Grapefruit Diet is suitable for both women and men.


  • There are no fat burner supplements incorporated into the Grapefruit Diet.
  • The Grapefruit Diet requires a rather drastic change in the user’s eating habits, which may prove quite difficult for some individuals.
  • There are no appetite suppressants involved in the Grapefruit Diet.
  • Regular exercise is discouraged for individuals on the Grapefruit Diet.
  • Only 800 calories can be consumed each day for those on the Grapefruit Diet, which could leave some users under-nourished.
  • The Grapefruit Diet can lead to low protein levels, cause dizziness and may result in a lack of vitamins and minerals.


The Grapefruit Diet is certainly an interesting one. There aren’t any diet pills or liquids involved and exercise is actually discouraged. On the bright side, this weight loss program provides the user with ample Vitamin C, antioxidants and Beta-carotene. However, the drastic lifestyle change that goes along with following this diet may not be so desirable for some individuals. Naturally it would be more attractive to more people if the Grapefruit Diet allowed the consumption of more than a mere 800 calories per day. It could also be more appealing if it encouraged a regular fitness regimen and came with some sort of appetite suppressant.

    I have been on the grape fruit dieet for 3 weeks the first week i lost 3kg and the next 2 weeks I haven’t lost anything. I walk 2km a day. Can anyone telling my why I have stopped losing weight?



    I am having the same issue.

    I started this diet on Monday. I weighed 260. Today is Wednesday and I am down to 255. I am excited to see what will happen after a month. I am doing the original version and I am eating extra bacon in the mornings because I love bacon. I try to eat all my veggies as well. I plan on adding some walking in order to be prepared for the walk for a cure 5k later this month. Fingers crossed!! In a couple months I plan to switch over to Paleo.

    I know it’s been a year since someone posted anything but for the heck of it. I tried the grapefruit diet. I follow it pretty much to a T and I’ve lost almost 16 pounds in 3 weeks. I don’t feel weak, moody or shaky. I eat a lot of salad at lunch with my protein and I eat a whole bag of veggies with my protein for supper.

    I drink 1 1/2 cups of coffee every morning it helps me to have a BM. The grapefruit diet says limit caffeine but then I saw where some people said they drank diet cokes and it still worked . If I drink my coffee first thing in morning and then eat my grapefruit and breakfast will it still work for me ?



    Do you drink black coffee with out sugar??

    can i eat a whole grapefruit before a meal


  • 9

    does anyone know more foods you can eat..or can anyone send me a menu please…good news i have been on the diet for 3 days and lost 6 pounds…bad news i have been eating the SAME thing everyday



    Try and eat some other fruits and have some chicken. Chicken doesn’t have calories, so it wont effect the diet as long as you don’t fry it bake it and if you can don’t add sauce and/or dressing to the mixture. I still don’t think its right. Remember that you shouldn’t do this because of how someone else feels but how you feel.



    Lean white meat chicken contains very little fat, but it most definitely contains calories. I used this diet many years ago, and it worked. I consumed about 1200 calories/day, and still lost weight. I am going to try it again very soon!

    I have not seen any true grapefruit diet on the internet in over 7 years

    It was given to me by a friend . it included a list of vegetables as long as your arm on what you can eat and a sizable list of ones you cant eat. Today’s sites that have the GF diet some say you cant have something and on another it says you can.U must eliminate all caffiene. and contrary to what this asswipe site says you dont count calories. and you dont have a protein shortage.


    unfortunely i dont remember and can no longer find the original diet.
    the best I can tell you is mainly leafy greens such as spinach and green leaf or romaine lettuce, parsley, cilantro. I have also found that carrots and tomatoes do not reduce the effectiveness of the diet. avoid starchy vegetables ( ie. potatoes and rice) and pasta like the not use diet/low fat dressings. there will be carbs in your dressing but you want to stay at or below 2g/serv. tho u may eat 1-2 serving per meal with 1-2 serving of salad. you could eliminate those by making you own low carb dressing.

    carbs hide in the least suspecting places. ie some sausages, hot dogs, some salad dressing are high in carbs. even though some of the diets say you can have these thing watch the carbs in them
    generally speak your half serving of grapefuit contains 10g carbs so that there is the 30. I have noticed that the more of the accepted vegetables (salad ) that you eat the more success. If you have no or limited success recheck what you are consuming. I figured out one time that cough drops that i was taking while on diet contained 15 carbs of sugar. OUCH!!!! I have never exercised on this diet.

    Is there any reason why this diet wouldn’t work if followed to the “T”? I’ve been on it for almost 4 weeks now and have lost NOTHING yet my girlfriend has lost almost 30 lbs. What gives? I’ve followed it exact and have no weight loss and she has even cheated and still lost weight? So, does this work for everyone or am I just the first it doesn’t work for? HELP I’m really commited and want to lose weight!

    i have been on a diet for 89 days and lost 21 lbs. but i do the military diet. and you can eat a lot of different foods, as long as you keep calories down to 900 or below, and be sure to take your omega 3 pills it helps a lot

    i really need to loose a lot of weight. my husband doesn’t know who I amanymore. the fat lady next to him in bed. i hope that this works. i just had a full masectomy and the only thing left is for me to loose 100 pounds plus. thanks for the info



    I don’t think that you need to loose weight this way, there are other ways…. loosing 10 pounds in 2 weeks is terrible, and it ruins your body, even if the effect of the fruit looks good. Don’t put yourself through this because of what others think, but of what you think of yourself.
