Watermelon On The Keto Diet: Approved Or Not?

The ketogenic, or keto, diet is a restrictive eating plan that involves limiting your carb intake and eating a high amount of healthy fats. The keto diet is designed to get you into ketosis, a metabolic state where your body uses your fat stores for energy instead of carbs. So, can you eat watermelon on a keto diet? The short answer is yes, watermelon can be keto-friendly. Compared to many other fruits, watermelon is relatively low in carbohydrates. One cup of diced watermelon contains approximately 11 grams of carbohydrates, including sugar and fiber. This means that depending on your overall diet, you may be able to consume watermelon in moderation while following a keto diet.

How does the keto diet work?

The keto diet is a restrictive eating plan that involves consuming a very low amount of carbohydrates and replacing them with fat. The aim is to force the body into using a different type of fuel. Instead of relying on sugar (glucose) from carbohydrates, the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat.

The keto diet is said to work by sending the body into a state of ketosis, in which the body begins using stored fat as fuel. This process produces ketones or acids that are released when the body breaks down fat for fuel. Our bodies naturally go into ketosis during periods of intentional or unintentional fasting, such as while sleeping. The keto diet aims to prolong that ketosis period for weight loss or to help with managing certain health conditions.

To achieve ketosis, it is recommended to consume fewer than 20 to 50 grams of carbohydrates per day. It typically takes a few days to reach a state of ketosis. Eating too much protein can interfere with ketosis, as protein can be converted into glucose if consumed in high amounts. Therefore, it is important to moderate protein consumption.

The keto diet has been found to be effective for weight loss and has been linked to improved health outcomes, including reduced risk of heart disease, cancer, epilepsy, and Alzheimer's disease. Additionally, the keto diet can help lower blood sugar and improve insulin sensitivity, making it beneficial for people with type 2 diabetes or prediabetes.

However, it is important to note that the keto diet also has some potential risks and side effects. It is high in saturated fat, which has been linked to heart disease. Other risks include nutrient deficiency, liver problems, kidney issues, and constipation. The keto diet may also cause fuzzy thinking and mood swings, as the brain functions best when using sugar from healthy carbohydrates as its energy source.

Before starting the keto diet, it is recommended to consult a doctor and a registered dietitian to ensure it is safe and to help incorporate the right types and amounts of carbs and fats.

Carb content of watermelon

The ketogenic, or keto, diet is a restrictive eating plan that focuses on extremely low carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day, with some sources suggesting no more than 20 grams.

Watermelon is considered a keto-friendly fruit because, compared to many other fruits, it is relatively low in carbohydrates. One cup (152 grams) of diced watermelon contains about 11.5 grams of carbohydrates and 0.5 grams of fibre, which equates to 11 grams of net carbs. Net carbs are the number of carbs in a portion of food that is absorbed by the body and are calculated by subtracting the grams of fibre from the total grams of carbohydrates.

Whether or not watermelon can be included in a ketogenic diet depends on what else is eaten throughout the day. On a 2,000-calorie diet, for example, carb intake may be restricted to 100 calories (25 grams) per day. Therefore, a single serving of watermelon could take up almost half of the daily carb allowance.

Watermelon can be included in a keto diet, but it may require careful planning and reduced portion sizes to keep within the daily carb limit.

Health benefits of watermelon on keto

Watermelon is a refreshing, hydrating, and nutritious fruit that can be enjoyed as part of a ketogenic diet. Here are some of the health benefits of including watermelon in your keto diet:

Low in Carbohydrates:

Compared to many other fruits, watermelon is relatively low in carbohydrates. One cup (approximately 152 grams) of diced watermelon contains about 11.5 grams of carbohydrates and 0.5-0.6 grams of fiber, resulting in around 11 grams of net carbs. This makes watermelon one of the lowest-carb fruits available. The high water content in watermelon also contributes to its low-carb nature, as fruits with higher water content tend to have fewer carbs.

Weight Loss and Satiety:

Watermelon can be a helpful addition to a weight loss journey when on a keto diet. A small study found that consuming watermelon daily can aid in weight loss, reduce Body Mass Index (BMI), and lower blood pressure. Additionally, watermelon can help manage some factors related to obesity and diabetes by providing a sense of fullness and reducing the urge to snack.

Improved Heart Health:

Watermelon is linked to improved heart health. It contains lycopene, an antioxidant that may help lower the risk of certain cancers and promote a healthier heart. The amino acid citrulline, found in watermelon, can be converted into nitric oxide in the body, which may help increase blood flow to the muscles and other parts of the body.

Antioxidant and Anti-Cancer Properties:

Watermelon is rich in antioxidants, including lycopene, which counteract the effects of harmful, disease-causing free radicals. These antioxidants may help reduce the risk of cancer development.

Hydration:

With a water content of 92%, watermelon is the fruit with the highest water content. This makes it an excellent choice to stay hydrated while on a keto diet, which can be dehydrating due to increased urine production.

Vitamin C and Immune Boost:

Watermelon is an excellent source of immune-boosting vitamin C. One cup of diced watermelon fulfills 20% of your daily requirement for this essential nutrient.

While watermelon is keto-friendly, it should be consumed in moderation as part of a well-planned ketogenic diet. It is recommended to work with a registered dietitian to ensure you are meeting your nutrient needs and staying within your daily carb allotment.

Other keto-friendly fruits

While on the keto diet, it is important to eat the right kinds of fruits to avoid exiting ketosis and stalling weight loss efforts. The keto diet is restrictive and requires strict adherence to maximize results, so fruits are often considered off-limits. However, there are several keto-friendly fruits that can be enjoyed in moderation as part of a well-planned ketogenic diet.

Avocados are low in carbohydrates and high in heart-healthy fats and fiber, as well as other important vitamins and minerals. Lemons and limes are also much lower in carbs than other fruits.

Certain types of berries can also be enjoyed in moderation. Strawberries, raspberries, and blackberries contain moderate amounts of carbs but are high in fiber, making them lower in net carbs.

Olives are technically categorized as a fruit and are a great keto option. A cup of green olives contains 5.18g of carbohydrates and 15.3g of monounsaturated fatty acids.

• Tomatoes
• Peaches
• Cantaloupe melon
• Star fruit
• Blueberries

Potential risks of the keto diet

Watermelon is a keto-friendly fruit. It is full of water and low in carbohydrates compared to many other popular fruits. However, despite its health benefits, the keto diet does come with some risks.

Firstly, the keto diet is extremely strict and difficult to maintain. It requires a high fat intake, which may lead to an increased risk of heart disease. This is due to the high levels of saturated fat in the diet, which have been linked to "bad" LDL cholesterol.

Secondly, the keto diet may cause digestive issues and changes in gut bacteria. It restricts carbohydrates, making it hard to meet daily fibre needs. This can lead to constipation and other digestive problems.

Thirdly, the keto diet may lead to nutrient deficiencies. By restricting fruits, whole grains, and legumes, the diet may not provide enough vitamins and minerals such as calcium, vitamin D, magnesium, and phosphorus.

Fourthly, the keto diet could cause dangerously low blood sugar levels, especially in individuals with type 1 diabetes. It may also lead to kidney problems, as the high protein intake can overload the kidneys.

Finally, the keto diet has been associated with impaired bone health in several studies. It may reduce bone mineral density and trigger bone breakdown over time.

Therefore, while watermelon is a suitable fruit for those on the keto diet, there are several potential risks associated with this eating plan that should be carefully considered.
