Grapefruit is a citrus fruit that is a cross between an orange and a pomelo. It is often considered a healthy food due to its low-calorie and high-nutrient content. However, the question remains: are grapefruits allowed on a keto diet?
The short answer is no. Grapefruit is not keto-friendly due to its high carbohydrate content. A single grapefruit can contain around 21-26 grams of net carbs, which can quickly exceed the recommended daily net carb intake of 20 to 50 grams for ketosis. Additionally, grapefruit juice is also not a good option as it has an even higher concentration of carbs and natural sugar due to the removal of dietary fibre during juicing.
While pink and red grapefruits have a lower carb count than other citrus fruits like oranges, their carb content is still too high to be considered keto-friendly. Therefore, if you are following a keto diet, it is best to avoid grapefruits and opt for lower-carb fruits such as berries, oranges, lemons, and limes instead.

What You'll Learn
Grapefruit is not keto-friendly due to its high carb count
The keto diet recommends consuming less than 20 grams of carbs per day to maintain ketosis. Grapefruit can quickly exceed this daily net carb count and interfere with ketone production, inhibiting or slowing down ketosis. Even grapefruit juice is not a good option, as it has an even higher carb count than the whole fruit due to the loss of dietary fibre.
If you are looking for a tasty and nutritious fruit to eat on keto, there are plenty of other options available, such as berries, oranges, lemons, limes, melons, and avocados. These fruits have a lower carb count and can be enjoyed in moderation while still maintaining ketosis.
In conclusion, grapefruit is not keto-friendly due to its high carb content. To stay in ketosis, it is important to limit your carb intake and choose fruits with a lower carb count than grapefruit.

Grapefruit juice is not keto-friendly either
As a result, grapefruit juice can quickly exceed your daily net carb count, which can interfere with ketone production and may inhibit or slow down ketosis.
In addition, grapefruit juice can also interfere with the metabolism of certain medications, increasing the risk of side effects and drug toxicity. This is due to the furanocoumarins in grapefruits, an organic compound that binds to a group of enzymes known as Cytochrome P450. These enzymes play a vital role in regulating how quickly toxins and drugs can enter the circulation.
Therefore, it is important to limit your grapefruit juice intake if you are trying to maintain a keto diet.

Grapefruit can interfere with certain medications
Grapefruit is a rich source of vitamin C and is often considered a healthy food. However, it is important to note that grapefruit can interfere with certain medications.
Grapefruit contains furanocoumarins, an organic compound that binds to a group of enzymes known as Cytochrome P450. These enzymes are located in the liver and small intestines and play a vital role in regulating how quickly toxins and drugs can enter the circulation. When furanocoumarins bind to Cytochrome P450 enzymes, certain drugs can enter the bloodstream in much higher concentrations, increasing the risk of potential side effects and causing excessive circulating levels of pharmaceutical drugs.
Some common examples of medications affected by grapefruit consumption include:
- Blood pressure medication
- Anti-anxiety medications
- Statin medications
- Organ transplant rejection medications
- Corticosteroids
- Arrhythmia medications
- Antihistamines
The American Heart Association (AHA) warns that grapefruit can interfere with certain medications and advises those taking drugs for high blood pressure, high cholesterol, allergy symptoms, or blood clots to talk with their doctor or pharmacist.
If you are taking prescription medication, it is crucial to consult with a healthcare provider or pharmacist to ensure that grapefruit or grapefruit juice will not interfere with your specific medications.

Grapefruit is a good source of vitamin C
In addition to vitamin C, grapefruit also contains vitamin A, or beta carotene, which is important for eye health and also supports the immune system and helps protect against inflammation. Grapefruit is also a good source of potassium, which can help lower blood pressure, and fibre, which can support heart health and weight management.
Grapefruit is a nutritious food that can be enjoyed in a variety of ways, including as a snack, in a salad, or blended into a smoothie. However, it is important to note that grapefruit can interfere with certain medications, so it is always a good idea to check with your doctor or pharmacist if you are taking any regular medication.

Grapefruit is a good weight-loss food
Grapefruit is often seen as a weight-loss food because it is low in calories and high in nutrients. A whole grapefruit has only around 100 calories, making it a great option for those looking to lose weight. It is also a good source of fiber, which helps keep you feeling full and satisfied after eating, preventing overeating.
Consuming grapefruit has been linked to significant weight loss in overweight patients. In one study, obese patients who consumed half a grapefruit before each meal lost on average 3 lbs more weight over 12 weeks than those who didn't consume any grapefruit.
Grapefruit also contains a group of phytochemicals called flavonoids, which have anti-inflammatory, antioxidant, anti-carcinogenic, and heart health-boosting properties. Naringin, a type of flavonoid found in grapefruit, has been linked to treating obesity, diabetes, and metabolic syndrome.
However, it is important to note that grapefruit is not a low-carb fruit and can quickly exceed your daily net carb count if consumed in large quantities. Therefore, it should be consumed in moderation, especially by those on a low-carb or keto diet. Additionally, grapefruit can interfere with certain medications, so it is important to consult with a healthcare provider before including it in your diet.
