What is the Grapefruit Diet?

The Grapefruit Diet is one of the oldest fad diets, going as far back as the 1930s. It was later popularized in the 1980s as a short term meal program that claimed it could help dieters lose up to 10 pounds in only 10 days.

The Grapefruit Diet is another low-calorie diet but with a special emphasis on consuming grapefruit. Grapefruit is a kind of citrus fruit that is rich in vitamins and antioxidants. It contains enzymes that help burn fat and is rich in water content which can help make a person feel full. With these qualities, the grapefruit took the limelight and another fad diet was made.

How does it work?

There are many variations to the Grapefruit Diet. Some allow the consumption of particular food like grains while some strictly don’t. In general, the Grapefruit Diet insists on the consumption of grapefruit with every meal. It also follows the low-calorie meal trend wherein a dieter is only allowed to eat up to 1,000 calories in a day.

A typical Grapefruit Diet plan suggests the following:

  • Cutting out foods with bad carbs and high sugar content.
  • Eating more protein like eggs, fish and red meat.
  • Drinking up to 8 glasses of water.
  • Last and most important of all, eating half a grapefruit or drinking 8 ounces of grapefruit juice before every meal.

This Grapefruit Diet plan seems like a natural hack for burning fats. It claims to help people shed 10 pounds in a limited time without having to go through starvation.

Does the Grapefruit Diet work? What are the benefits of the Grapefruit Diet?

Most fruits, including grapefruits, are beneficial to people. It is possibly beneficial for dieters to follow the general proposition of the Grapefruit Diet, which is essentially adding half a grapefruit to a meal plan. Grapefruit can help reduce insulin levels and help dieters feel full which are big plus factors for weight loss. So, eating grapefruit with a balanced meal can yield good results.

Grapefruits have very low calories and also has high fiber and water content. It is also rich in vitamins and antioxidants. Therefore, the Grapefruit Diet promotes an alternative diet to help reduce weight fast while being assured of having nutrients that the grapefruit offers. These are the coveted benefits that make people try it out.

It must be noted, however, that besides a few research on the benefits of eating grapefruit and how it can help with weight loss, there is yet to be a scientific study proving the efficiency of the Grapefruit Diet.

Is the Grapefruit Diet safe? Is the Grapefruit Diet unhealthy?

Low-calorie diets can be dangerous for those with age-related conditions and digestive issues. The Grapefruit Diet also falls under this category which risks dieters with the aforementioned health problems. Even for people who don’t have medical concerns, this diet can have harmful effects without proper guidance or professional advice.

Additionally, grapefruits can also cause fatal problems for people taking certain medications. It is unsafe to consume this citrus fruit while taking drugs like some antihistamines, birth control pills, and anti-anxiety medicines. The U.S. Food and Drug Administration (FDA) has released a publication tackling the dangers of consuming grapefruit juice or grapefruit along with a list of some types of medication that don’t go well with the fruit.

Finally, the Grapefruit Diet has no official studies to prove its effectiveness. The purported pieces of evidence that support its claim of losing 10 pounds in 10 days are mostly in the form of reports or feedback from people who have tried it. Moreover, the quick fix of the diet also has no link to long-term weight improvement unless the dieters continue with other types of eating programs. It is not advised to stick to this low-calorie diet as people may not get enough nutrients to keep their bodies healthy.
