The grapefruit diet has been around since the 1930s and has evolved ever since creation because of the many variations that it has now. It is one of the quick diets because you can lose up to 10 pounds for 12 days.

The diet is not a single diet where you can only eat just one kind for a week. It consists of much more than the grapefruit itself because it incorporates the fruits in every protein-rich meal plan. The meal plan of the diet is strict and can give you 800 to 1000 calories a day.

The grapefruit diet can help you lose weight because of the fat-burning enzymes that the fruit has. You don’t need to engage in physical, intense activities for you to lose weight.

How Does Grapefruit Diet Works

The Grapefruit Diet is a diet that is low in calories and carbohydrates and has moderate protein. It will give you around 800 to 1,000 calories per day that will help you lose weight. With the diet plan, you will lose weight with or without the grapefruit.

There are still no scientific studies that can back up why grapefruit enzymes can help you burn fat and why it is on the grapefruit alone and not in the other citrus fruits. A study thought that including grapefruits in your meals can reduce insulin levels that can promote weight loss. It can also help enhance physical activity that can help you lose weight.

Consuming grapefruit is nutritious because it has vitamin C and fiber that is a component you need for a fat burner. It is a low-calorie fruit that you can enjoy eating without worrying you’ll gain weight.

Benefits Of Grapefruit Diet


The Grapefruit Diet has a lot of good benefits that can help your overall health.

Side Effects Of Grapefruit Diet

The Grapefruit Diet can help you lose weight, but there are some side effects that you should be aware of and can be unhealthy.

Only Temporary

The diet is temporary and would not be a good plan for the long term. You will eventually gain back the weight you lost during the weeks you have been taking the diet.

Health Drawbacks

The diet can be unhealthy for your body because of the low-calorie content that you are getting daily. You may lose weight, but it won’t be healthy for your body as it can weaken your bones, lower your metabolism, and cause weakness and fatigue. You can also have nutrient deficiencies and lose your muscles.


The diet is very restricted when it comes to its meal plans and you can get bored eating the same thing every day. It doesn’t have many varieties that will make you stick to your diet plan.

How Safe Is the Grapefruit Diet?

Grapefruit is considered safe and can help your balanced diet, but the fruit can interfere with some medications. If you are using the following medications, you need to consult your doctor before you get through with the grapefruit diet.

Here are the following medications that grapefruit can interfere to:

Final Thoughts

final thoughts

If you are looking for a quick weight loss fix, then the Grapefruit diet is proper for you. It is popular in Hollywood because of how drastic weight loss it can give you. Imagine losing a lot of weight in just a few weeks. No wonder celebrities and influencers use this, especially if they are working on essential projects that require them to lose weight immediately.

The diet follows a strict diet plan that you can only eat and should be followed if you want to lose weight. The diet plan's food is low calorie that can help you sustain energy throughout the day. The grapefruit itself included in the list will give you vitamin C and fiber to help you burn fat. However, I’m not too fond of the diet because you can quickly lose weight, but you can also quickly get it back again once you get back to your regular diet.

I would recommend the grapefruit diet for those who want a crash diet that they need. It could be for a wedding, a pictorial, or you want to fit in your bikini for the summer. As you read, it is not a good plan for the long term because it can have some side effects on your health which isn’t advisable for any health buff.

I hope this grapefruit diet review will help you decide if this is the proper diet for you.
