Is Grapefruit Good For Weight Loss?

This article has been Fact-Checked by Kendall Kennedy MS, RD, RYT

There is no shortage of foods that supposedly help you burn fat. Grapefruit is one of them, is it good for weight loss or not?

Grapefruit is a citrus fruit known for its distinctive sour/sweet/bitter taste.

It’s also often mentioned as a “detox” fruit. Let’s see if it lives up to the hype.

Micronutrients in grapefruit

The first thing to look at is the amount of micronutrients in grapefruit.

Micronutrients are a group of nutrients your body absolutely needs to survive and thrive. Micronutrients include vitamins and minerals. These are involved in basically every aspect of your health, including weight loss.

100 grams of grapefruit provides you with approximately (1):

  • Vitamin C: 52% of the DV (Daily Value)
  • Vitamin A: 23% of the DV
  • Potassium: 4% of the DV
  • Thiamin: 3% of the DV
  • Vitamin B6: 3% of the DV
  • Folate: 3% of the DV

And a few other micronutrients in smaller amounts. While the vitamin c and vitamin a levels are good, the rest of the micronutrients is not that noteworthy compared to a lot of other whole foods.

Grapefruit also contains a few anti-oxidants, substances that help your body deal with stress from oxidation.

Fiber in grapefruit for weight loss

Another very important thing to look at in your weight loss food is the amount of fiber present.

Grapefruit contains around 1.6 grams of fiber per 100 grams. This is a decent amount of fiber per 100 grams.

Fiber has multiple benefits. First of all, it feeds your microbiome, the microbes that live in your intestines. The health of your microbiome influences your body’s health and weight. Feeding it well is usually not a bad idea.

Fiber also helps you feel less hungry without adding a lot of calories to your diet. Hunger and cravings can be a big pitfall for people trying to lose weight, so avoiding this is a big plus.

Should you eat grapefruit for weight loss?

Let’s take a closer look at the macronutrients in pineapple.

42 calories per 100 grams. 38.2 of these calories come from the carbohydrates (10.7 g per 100 gram of which 1.6 g fiber).

This is a rather low amount of calories. Grapefruit is not the greatest for low-carb diets like the keto diet but you should be able to fit some in if you want. It still makes the list of low-carb fruits.

Grapefruit is certainly an option for a weight loss diet. It will help you fill up without adding too many calories to your diet. That being said, there are also better fruits for weight loss.

If you’re looking for a boost in micronutrients you might want to look at other foods.

While grapefruit is a bit overhyped in terms of weight loss, it can certainly help if you replace processed foods with grapefruit.

Who should avoid grapefruit?

Some people want to avoid implementing grapefruit in their diet altogether.

The first kind of situation where that is the case is when taking certain medications. Some examples of medications that may interact with grapefruit intake include (2):

  • Immunosuppressants
  • Some statins
  • Benzodiazepines
  • Most calcium channel blockers
  • Indinavir
  • Carbamazepine

If you take any of these you want to consult a healthcare professional before adding grapefruit to your diet.

Secondly citrus fruits, including grapefruit, may lead to teeth erosion (3). If you have sensitive teeth you may want to avoid eating grapefruit.
