Grapefruit 7-Day Diet Plan & Menu [2019 Updated]

The 2 Week Diet

grapefruit diet meal plan

The grapefruit diet is a low carb diet plan that has been around for years and the fruit itself has always carried a lore associated with weight loss. 
But, does it actually work?

Well, the grapefruit diet plan works as with most restrictive fad diets but it should not be followed for a long period of time because the body would suffer from a lack of iron, calcium and other necessary nutrients.

If you're serious about losing weight in just a few days, then read this whole article to understand whether this low-carb diet is something you can do or not, based on the daily meal plan, calorie restrictions and other grapefruit diet rules.  

What is the grapefruit diet?

The secret of the grapefruit diet lies in one of the properties of this fruit: it calms the feeling of hunger. It is also very diuretic and will allow us to burn and eliminate fat easily. But you should remember, this is a fad diet aka a semi-fast diet plan that can not be followed more than two weeks since it is based only on the consumption of grapefruit juice, and salads.

Generally, it is not advised to follow a low-calorie diet (less than 1000/day calories) unless under the guidance of a doctor, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

The grapefruit diet has many similarities to the famous Atkins diet. In the grapefruit diet, you start the day by eating protein-rich foods; eggs, bacon along with black coffee and either half a grapefruit or a glass of grapefruit juice. 

Does Grapefruit Burn Fat?

Scripps Research Institute, one of the largest privately funded research organization in the world put grapefruit to the test. 

When 91 obese patients consumed grapefruit 3 times a day, before each meal, in different forms:
grapefruit study

  1. Placebo capsules and 7 ounces (207 mL) of apple juice
  2. Grapefruit capsules with 7 ounces (207 mL) of apple juice
  3. 8 Ounces (237 mL) of grapefruit juice with a placebo capsule
  4. Half a grapefruit with a placebo capsule

The results have been eye-opening. Grapefruit supplementation was associated with weight loss in subjects related to metabolic syndrome; high blood pressure, high blood sugar, excess body fat and abnormal cholesterol or triglyceride levels. 

The study was led by Dr. Ken Fuijioka in the department of Nutrition Metabolic Research Center at Scripps Clinic found that people who ate half a grapefruit with every meal and made no other dietary changes recorded weight loss at an average of 3.5 lbs (1.6kg), while those who drank a serving of grapefruit juice three times a day lost 3.3 pounds (1.5kg). And subjects who took grapefruit capsules before every meal lost 2.4 lbs (1.1kg).

Furthermore, the research indicates a physiological link between grapefruit and insulin, as it relates to weight management. The researchers speculate that the chemical properties of grapefruit reduces insulin levels and encourages weight loss.

"Grapefruit appeared to encourage weight loss by decreasing levels of the fat storage hormone, insulin" says lead researcher Ken Fujioka, M.D. who adds there may be a potential for weight loss from eating smaller amounts. 

Although, it's fair to mention that the link between raised insulin levels and excess weight is complicated and multifaceted. 

High levels of the insulin hormone stimulate the brain's hypothalamus, causing feelings of hunger. They also stimulate the liver to manufacture fat that can constrict arteries, leading to heart attacks and strokes. 

This study of grapefruit potential in lowering insulin levels that leads to weight loss is an exciting discovery. But without taking other factors into consideration like calorie intake, foods consumed and exercise habits, things are far from conclusive.

Grapefruit Diet Menu & Guidelines

grapefruitThe grapefruit diet menu was introduced by Kelly D. Brownell in the year 1930. The overall diet is made up of protein-rich foods, vegetables, and less fat. 

Before we launch into the vast array of food choices, Let’s look at the basic rules for the grapefruit diet:

  • At any meal, you must eat one-half of a grapefruit or drink 1 cup of unsweetened grapefruit juice.
  • You have to drink eight 8 glasses of water daily, that's half a gallon of water (about 2 liters) because grapefruit is very diuretic and it is necessary to hydrate continuously.
  • You must eat the minimum listed at each meal. You cannot cut off anything from the diet, especially the bacon and the eggs at breakfast. 
  • The grapefruit or fruit juice plays an important role because it performs as a catalyst that begins the burning process. Do not add or lower the amount of grapefruit or juice.
  • Reduce coffee; it affects the insulin balance that delays the burning process. Try to control to 1 cup at mealtime.
  • Don't eat between meals. If you eat the recommended foods you will not easily get hungry.
  • Cut off on desserts, bread, and white vegetables or sweet potatoes.
  • You may double or triple servings of meat, salad or vegetables.
  • Exercise during the diet is not recommended due to the severe restriction of calories. 
  • The grapefruit diet last for 3, 7 or 12 days only! a dieter who decided to continue carrying-out the diet plan must take at least 2 days off.

Grapefruit food list and guidelines

Grapefruits will help you to stay away from foods that sabotage your weight loss efforts including:

Sweets: Cakes, Cookies, Pies, Doughnuts, Candy, Ice Cream, etc...

Sweetened Beverages: Colas, Root Beer, Fruit Juice Drinks, Soda...etc

Sugar: Added to Coffee, Tea, Cereal, etc....

Read between the lines and you’ll find that many low-fat foods are pushed overboard into the high-calorie danger zone because of the way they're prepared.

A plain baked potato is zero fat and 150 calories. Leave off the butter and sour cream and use seasonings or soy sauce. Watch out for stuffed vegetables – if they’re stuffed with breading you’re back to square one.

Fish is healthy but not if served breaded, fried, or swimming in sauce.

A typical restaurant meal consisting of deep-fried mushrooms, a ten-ounce steak, large baked potato with sour cream, buttered peas and cheesecake contains 2,000 calories – more than many women’s daily caloric intake and more than enough fat for an entire week.

Substitute salad with dressing on the side for the fried mushrooms, broiled skinless chicken breast for the steak, steamed vegetables for the buttered peas, and a slice of angel food cake for the cheesecake and you’ve cut the damage by more than 1,200 calories and significantly reduce fat calories.

    Grapefruit benefits
    A single grapefruit contains about 70 calories.  A serving of grapefruit juice has about 90 calories and loads of nutritional value. It is an excellent source of vitamin C, dietary fiber, vitamin A, potassium, folate, and vitamin B5. Grapefruit also contains phytochemicals including liminoids and lycopene.

    The rich Vitamin C helps guard your body against harmful elements that could potentially damage your immune system. Grapefruit nutrition is especially important for expecting mothers because the vitamin C helps the baby grow, and aids in absorbing iron out of other foods.

    Other grapefruit nutrition like the potassium upholds fluid in the body and electrolyte stability in the cells. The potassium also helps muscles contract, and discharge of energy from protein, fat, and carbohydrates throughout the body’s metabolism.  Folate helps adapt homocysteine levels in the body. In a recent study, it was found that low levels of folate have actually been connected with low energy levels, depression, and even some memory loss.
