What Is The Grapefruit Diet?

The grapefruit diet plan was introduced in the US in the 1930s and it varies vastly across the US.

Some Grapefruit diet plans are very strict and demand that a person eats only grapefruit and drinks only its juice for ten full days! 

Other grapefruit diet plans are more flexible and allow a person to eat protein and fiber-rich foods (both Veg and Non-Veg) along with a glass of grapefruit juice three times (during breakfast, lunch, and dinner) a day.

In the flexible grapefruit diet plan, a person consumes less than 1000 calories a day to stay in shape and in the rigid grapefruit diet plan, a person only burns calories by eating only grapefruit and drinking only its juice.


The Grapefruit Diet & Dietary Restrictions

Both the grapefruit diet plans forbid the intake of carbs and starch-rich food like rice, flour, potato, etcetera as that would be detrimental to the desired results. Consumption of other fruits is also forbidden. 

They also forbid a person from doing exercises as that requires a lot of energy and the grapefruit diet program gives a person very little calories.  

The main claim/attraction of the grapefruit diet program is that it helps people lose fat and weight quickly (a few pounds within a week). During the 1930s, many Hollywood actors and actresses endorsed this diet program and claimed that it helped them lose fat and weight quickly and stay in shape. 

It was for this reason that the grapefruit diet program had nicknames like ‘10 Days 10 Pounds Off’ program or the ‘Hollywood Diet’ program.


How Grapefruit Diet Works

The grapefruit juice diet program is based on the qualities of the grapefruit to aid in weight-loss and to maintain nutritional levels in the body. Grapefruit is rich in Vitamin C, Vitamin A, fiber, and various minerals. It also has trace amounts of protein. It is also low on calories. It contains only 69 calories.

The Vitamins and fibers present in grapefruit help the body breakdown and burn fat quickly. Since it takes 100 calories to digest a grapefruit and since it gives only 69 calories in return, the body loses 31 calories every time it digests a grapefruit. 

The various minerals and proteins present in grapefruit are used by the body for various purposes. Thus the grapefruit diet program helps a person lose fat and weight quickly while at the same time giving him all the nutrients he needs for maintaining good health.


What to eat on the grapefruit diet?

Kindly brace yourselves. The flexible kind of grapefruit diet program allows a person to eat protein and fiber-rich foods along with a glass of grapefruit juice during mealtimes. The foods can vary depending on whether a person is a vegetarian or a non-vegetarian. 

In our article, we are only going to discuss the non-veg foods that are had with grapefruit juice.

The Grapefruit Diet Chart

The recommended grapefruit diet chart is as follows:

Breakfast 2 eggs, 2 slices of bacon, black coffee and a glass of grapefruit juice.
Lunch Vegetable salad, red meat of any kind and a glass of grapefruit juice.
Dinner Vegetable salad not containing peas or corn or potatoes, fish or meat of any kind and a glass of grapefruit juice. 

This chart must be followed for 10 to 12 days without fail to get the best results. Following this chart religiously will reduce a person’s fat and weight and keep him healthy. 


What you can’t eat on a grapefruit diet program

Don’t worry, it’s not as bad as you think. The grapefruit diet program restricts a person from eating foods that are rich in carbs and starch like peas, corn, potatoes, milk, rice, cereals, and sweets. Eating other fruits is also not allowed. One glass of grapefruit juice should be had after every meal.

No item in the diet chart should be omitted because every item plays its part in reducing the fat and weight of a person. Even if one item in the chart is omitted, it can cause the whole grapefruit diet program to become a failure.


Why the Grapefruit Diet Results Are So Amazing?

I’m sure that you’re all keen to know this so let’s dive right in. This topic is still under debate. Some people, including Hollywood stars, have claimed that it has helped them shed fat and weight quickly and stay in shape. 

Some scientists in the US have questioned this program’s credibility and said that it didn’t work on them. Some people have said that they have benefited only marginally from this program. 

Since this topic is controversial, I have listed a few reviews from people. Kindly read them and decide for yourself whether this program is worth undertaking.
