Grapefruit Diet


The epitome of a fad diet, though many say it works.


The grapefruit diet is really just a set of standard rules you follow for mealtimes. There are some variations in the rules, but they usually look something like this:

o Drink 8 8oz (64oz total) glasses of water each day.
o When eating a meal, stop when you are full.
o Follow the meal-plan (below) exactly, no substitutions and you have to eat everything listed. No snacking
o Do the diet for 12 days, then take a break for 2 days.


grapefruit ( or 8oz of grapefruit juice)
2 eggs prepared any way you choose
2 slices of bacon


grapefruit ( or 8oz of grapefruit juice)
salad with the dressing of your choice
all the meat you want


grapefruit ( or 8oz of grapefruit juice)
salad with the dressing of your choice OR a red or green veggie prepared with butter/spices
any meat or fish
1 cup of coffee or tea

Bedtime Snack:

1 cup of skimmed milk or tomato juice

The grapefruit juice is suppose to be a catalyst that helps burn fat. Coffee hinders fat burning, so you're limited to that 1 cup per day. You can basically eat all the meat and fat you want. Exercise is generally encouraged as well.

There are some supplements on the market that leverage the grapefruit diet as part of their gimmick.


It is believed this diet started in the 1970s. It was so simple, it could be printed on a single sheet of paper and photocopied to share with others.


Many health professionals and organizations have stated they diet is not healthy. Though recent studies seem to have shown it really does work.

posted 2-Oct-2012 10:28am

Hi Afanta Im going finish this round Ive lost 6lbs since last Monday. Thats not too bad. I gained some on my days off 4lbs...But I cant complain. Its still.coming off. If it stops after a week Im going to switch over to Atkins. I need to lose 21 more lbs. Atkins works too. Youre right your body needs a recharge sometimes. Atkins might do it. Well see what happens when I go 1 more round of this. My plqn was to switch over anyway to reintroduce carbs to my body. Im still pretty happy with the results 19lbs in little over a month. Cant complain! :)

bea can u please post the meal plan for atkins... and also can u say me where i am going wrong in grapefruit diet?????
posted 2-Oct-2012 10:47am

DTS, don't know, each person react differenly. there is a lady she drink the juice but not losing any pounds but when she starts to eat real grapefruit, she start to lose. really, there is no reason, you have to keep on trying whatever way work for you. Also are you sure you didn't take any sugar?
posted 2-Oct-2012 10:49am

Bea, right I don't complain but just feel frustrated when you work hard on it. I don't know why only 2 round success and then after, never sucess......

I tried the other diet during that 5 month off but none I get back to grapefruit diet. It works for me last week but this week......humm, i will see, it is only 5 days left. I will not take that 2 days off and keep going another 12 days and see what will happen.

ok, do this way, instead of half grapefruit you eat now, try eat 3/4 fruit per meal and see what happen
posted 2-Oct-2012 12:39pm

dts you have to eat or drink the grapefruit. now that were talking about it ive been.drinking the juice because i cant find and grapefruit here. That might have slowed things down. Ill see if I can find any today and let everyone know...

posted 2-Oct-2012 4:15pm

DTS, please measure yourself and keep it in record, when you finish 1st around, see you have some inch lose, maybe you lose in inch, not the weight yet
posted 3-Oct-2012 8:47am

should i eat 1 full grape fruit or a half of it...
posted 3-Oct-2012 9:57am

DTS, it should be 1/2 grapefruit or 1/2 cup juice. But maybe your grapefruit is small, so try eat a bit more. if you don't have stomach problem, you can try 3/4 or 1 full each meal and see it works for you......
posted 3-Oct-2012 10:02am

i didnt lose anything but i think its because im not eating enough food. Going to try to resolve that today and see what happens by Saturday. Wish me luck!
posted 3-Oct-2012 10:20am

Bea, you mean we have to eat a lot of meat in order to make it works?
posted 3-Oct-2012 11:42am

DTS, Bea, see below, very helpful inform

You must drink eight 8oz. glasses of water daily (64 oz. total per day).
At any meal you may eat until you are full.
You must eat the minimum listed at each meal. (yep, this diet list the minimum you should eat).
You cannot eliminate anything from the diet. Especially the bacon at breakfast and the salads. You must eat the bacon and salads. These combinations of food burn the fat, omitting one part of the combination will cause the whole thing not to work.
The grapefruit or fruit juice is important because it acts as a catalyst that starts the burning process.
Cut down on coffee, it affects the insulin balance that hinders the burning process. Try to limit to 1 cup at meal time.
Don't eat between meals. If you eat the suggested foods you will not get hungry.
You can fry food in butter and use butter generously on vegetables.
Do not eat desserts, breads, 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 the more weight you will lose.
Stay on the diet 12 days, then stop the diet for 2 days and repeat.

My goal was to be at 183 by Saturday. So far Ive lost 20lbs. 20 more to go! I know the diet says not to exercise but I do. I keep my heart rate up during that time to optimal. Not sure if that will help you or not.

posted 6-Oct-2012 11:23am

Hi Zoeee, if you want to lose weight, you have to give up something for that 10 days. Zoeee, when you want to drink a wine, just think it will make you dead.....and you will give it up or drink some diet coke to replace it. you have to make yourself eat full so you want think other food or drink, keep on drinking water.

also think after 10 days you have 6 lbs off and then you can have a wine again......

if you don't follow the diet, then don't do it.......that is the rule

Zoeee, if you really like to drink, make sure you have 1/2 cup each time and no more than 3 per week, and check you can have weight lose. it is same as me when i have the diet 1st time. cut out sugar is very hard as i love chocolate.......and i still eat that but make sure myself no more than 3 per week......and i do still have weight lose.........follow the diet is not easy but make sure you keep it at least 95%

Anonymous yes, you can fried any type of meat without flour or any type of breading. Frying with lots of flour, breading and batter is more of a Western thing; most people of other countries (Caribbean, Indians, African, etc) does not really fry with a lot of flour or batter. Maybe that's why they are so much slimmer. Just need to make sure that the oil or butter is hot not just warm.

dd i did the zone diet for awhile watching my calorie intake. But it stopped working. I tried other things. Now Im doing this but Ive had to tweak it a bit. Im defenitely not losing anywhere near 14lbs in 2 weeks at first I lost about 11 or 12 now it varies about 3 or 4 every 2 weeks. Ive also gained on my days that slowed it down considerably. Im 182 today lost 23lbs. 17 more to go! I started end of August. Im hoping to have it all off by Jan 1. I eat cheese now and other proteins. I stay away from carbs. I eat sugar free. I still eat the grapefruit. Most of my meals include salad with bacon and lots of non light dressing. I stay away from red meat most times. I like chicken turkey fish shrimp. I keep my protein intake above 70 grams but below 100..its hard on your kidneys. I also take a multi vitamin. I drink a lot of water. How much do you have to lose?

bea, i tell you 1 thing, this diet only work if you are never take it before and only work for 2 to 3 round, that it. after that, no matter what you eat, it will drop 2 to 3 but give you back 2 to 3, so you are stay on the same.

i will switch to 1200 cal diet but will only take carb for 1 meal only, either breakfast or lunch. I will remove the grapefriut from my meal as I think my body doesn't like it anymore as there is no reaction anymore. I will still keep the sugar away but not ask my mom to remove from cooking, that is hard for her....

When you loose the weight just like any other diet its best to watch what you eat!! This diet basically teaches you how to eat more healthier. Just follow the diet exactly and you should be fine!! I lost more weight during my first phase!!
