Grapefruit Diet
The Grapefruit Diet is a weight loss diet built solely around the humble grapefruit.
The idea that a single item of food has miraculous weight loss properties seems a farce. The grapefruit is a marvelous fruit – a natural simple carbohydrate high in fiber and vitamin C. But to use it as the sole foundation of a weight loss program is unwise. However recent research has discovered that the grapefruit has more to it than meets the eye.
A lot of the grapefruit diet plans that have been circulating are very low calorie diet plans (VLCD’s) with a grapefruit thrown in. VLCD’s are not a good weight loss solution for many people. Most versions of the Grapefruit diet are identical to the Mayo Clinic Diet.
Grapefruit Diet – Meal Plan
Below is the outline of the fad diet – and it IS NOT RECOMMENDED. Note that there is also substantial evidence that grapefruit (unlike any other citrus fruit) can interfere with medication.
12 days on – 2 days off
| Breakfast 1/2 Grapefruit or 4 oz. Grapefruit Juice (unsweetened) 2 Eggs (any style) 2 Slices Bacon |
| Lunch 1/2 Grapefruit or 4 oz. Grapefruit Juice (unsweetened) Meat (any style, any amount) Salad (any kind of dressing) |
| Dinner 1/2 Grapefruit or 4 oz. Grapefruit Juice (unsweetened) Meat (any style, any amount) (fish may be substituted for meat) Vegetables (any green, yellow, or red vegetables cooked in butter or any seasoning) |
| Bed Time Snack 1 glass tomato juice or 1 glass Skim milk |
| Vegetables Allowed Red onions, green onions, bell peppers, radishes, cucumbers, broccoli, spinach, lettuce, cabbage, carrots, peas. |
| Vegetables to Avoid White onions, potatoes, celery. |

Instructions
- At any meal you may eat until you are full – until you can’t eat any more.
- Don’t eliminate anything from the diet, especially don’t skip bacon at breakfast or omit salads. It is the combination of foods that burn fat.
- The grapefruit is important because it acts as a catalyst that starts the burning process.
- Cut down on caffeine- it affects the insulin balance that hinders the burning process. Try to limit to 1 cup per meal at mealtime.
- Don’t eat between meals. If you eat the combination of food suggested you will not be hungry.
- Note that the diet completely eliminates sugar and starches, which are lipids and form fat. Fat doesn’t form fat; it helps burn it. You can fry food in butter and use butter generously on vegetables.
- Do not eat desserts, bread, and white vegetables or sweet potatoes. You may double or triple helpings of meat, salad, or vegetables. Eat until you are stuffed. The more you eat of the proper combination of food, the more you lose.
Properties of the Grapefruit
The traditional grapefruit diet consists of a 7 or 21 day eating plan. 1/2 a grapefruit is consumed during breakfast, lunch, and dinner.
Recently the Scripps clinic, based in San Diego carried out a clinical trial and discovered the following:
“The 12-week pilot study, led by Dr. Ken Fujioka, monitored weight and metabolic factors, such as insulin secretion, of the 100 men and women who participated in the Scripps Clinic “Grapefruit Diet” study. On average, participants who ate half a grapefruit with each meal lost 3.6 pounds, while those who drank a serving of grapefruit juice three times a day lost 3.3 pounds. However, many patients in the study lost more than 10 pounds….. The researchers speculate that the chemical properties of grapefruit reduce insulin levels and encourage weight loss.”
By all means include grapefruit in your diet – it may give you an edge. But for serious and sustained weight loss – look elsewhere.


This is a great diet. I have lost 30 lbs in 3 weeks. I also, lost 16 on weight watchers.
I am 204 pounds. I will try this tomorrow. It is May 18, 2008 today. I will keep you guys posted. Goodluck to me!
ill try this diet…
Umm.. I’m a vegie.. is ther no way I can replace the meat with something else?
i tried this diet and it really doesnt work well but if you want to get stomach ache then go ahead and try it
Today i am 185 pounds i am going to try this diet.
I am 200 pounds and I’m 5’9. since I can’t exercise on this diet, will I have flabby skin when I lose about 40 to 50 pounds?
I have been on this diet for a couple of weeks and am losing an average of 1 lb every other day. I started at 184 and am now at 174. It’s somewhat difficult to eat only meat and veg, but it does work if you want a kick start or have quite a bit to lose. As with any “diet”, no it is not a sustainable way to eat forever, but it is a way to eat to lose for a number of months. I am also working out vigorously 40 minutes a day so that when I reintroduce carbs back into my diet, I don’t regain all the weight.
All these questions about how long does it take to lose the weight are irritating!!!. Just try the diet and see if it works. Besides, if you really need to lose the weight, then it really doesn’t matter how long it takes. Also, everybody know that if you are heavier, then you will drop quicker, versus someone who is smaller and only needs to lose 10 lbs. Me, I tried this diet and lost 60lbs in 8 months (for those of you who just HAVE to know how long it took!!) It does help you lose weight, but I did gain 5 back, so trying to stay on track. But anyway, try the diet, it works.
How many pounds can you lose in a week with this diet
I am taking bloodpressure and water tablets,will this diet affect the meds?.
did all of you who lost like 40 and 50 pounds just do it for the week? Like how long for you to lose 50 pounds?
how long did it take you, to lose 50,40 pounds?jackie ,sally
who leaves comments on a diet page????
I tried it and it work But you lose more weight if you exercise!!!
i am not a doctor but medically speaking pure grapefruit juice is not really good for you because of the acid, but it does work
Yes the diet really works. I tried it and lost 40 pounds. You do not need to exercise with it. Try it before you knock it.
i have tryed this diet and it works i have lost 50 pounds
Get a life, arguing about a diet on the internet, if you dont want to do it don’t, and if you do, do. Then you have all the proof yourself.
Some people are truly the incarnation of laziness.
i asked YOU to prove it. not google
You’re really lacking braincells aren’t you? Simply copy a sentence of the above quote into the Google browser and it will show you a page with the COMPLETE quote.
prove it
And, if you read on from the above quote rather than where it’s been conveniently cut off, you see that all of these participants have actually increased their exercise regime whilst trialling this diet!
O_o… okay then…
Simply put, telling people to eat more, or until stuffed will NOT help lose weight! you actually have to be a partcipant of healthy activity! Not just eat and add a grapefruit to the meal and expect to lose it!!
((above comment was me))
I NEVER SAID THAT!!! *shakes fist menacingly*
and anyway, why don’t YOU explain whats bad about it
So does that mean you’re a supporter of said diet? What’s your proof?!
This is annoying. The website’s continuously saying ‘it’s a bad diet. it’s a bad diet’ but it won’t say WHY. hello?
Yeah, the idea of the grapefruit diet doesn’t seem to be far too bad, but rather than encouraging people to eat until ‘stuffed’, really, people should be encouraged to live an active life with more thought given to excersising instead of eating until over full.
