With only 85 calories per serving, watermelon makes a perfect snack between meals. It's healthy and refreshing, providing both flavor and nutrition. Plus, it fills you up quickly and curbs sugar cravings.
The watermelon diet, though, won't necessarily help you get in shape for the summer. In fact, you might end up gaining weight once you return to normal eating.
This diet plan requires eating nothing but watermelon for five to seven days. It's too low in calories and may lead to nutrient deficiencies. In the long run, it can slow down your metabolism and affect lean body mass.
What Is the Watermelon Diet?
Sounds good, doesn't it? There's a catch, though. You must eat nothing but watermelon for five to seven days — or even 10 days. That's rule number one.
The second rule says that dieters must eat 1 kilogram of watermelon for every 10 kilograms of body weight. Some versions include two or more phases to help you keep the pounds off.
Does It Work?
Just like the pineapple diet or the cantaloupe diet, this slimming plan is low in calories and lacks variety. To put it simply, it's a crash diet that limits your food choices and can take a toll on your metabolism.
According to a 2018 study published by the European Society of Cardiology, crash diets may accelerate weight loss, lower blood pressure and improve diabetes symptoms. The downside is that they may affect cardiovascular function and worsen existing heart problems. Subjects who followed a diet providing only 600 to 800 calories per day experienced a 44 percent increase in heart fat levels after just one week.

As you can see, this fruit offers more than one-third of the daily recommended intake of vitamins A and C. These nutrients exhibit antioxidant properties and may protect against heart disease, cancer and free radical damage. Watermelon is also a good source of l-arginine, l-citrulline and various antioxidants that may help decrease post-exercise inflammation and boost immune function, according to a 2016 review published in the journal Nutrients.
Watermelon benefits your heart too. A 2014 study featured in the American Journal of Hypertension found that this fruit may reduce cardiac stress and aortic blood pressure in obese adults. Lycopene, one of the most abundant antioxidants in watermelon, may lower your risk of diabetes and heart disease.
Delicious Ways to Enjoy Watermelon
The watermelon diet alone may not be healthy, but the fruit itself packs a hefty nutritional punch. Replacing your go-to snacks with watermelon can help reduce your calorie intake and keep you full longer, making weight loss easier.
If you're craving dessert, dip this fruit in dark chocolate and let it set in the fridge. To make ice cream, blend watermelon, coconut milk and vanilla extract, and then freeze the mixture for about half an hour.
Experiment with watermelon smoothies, lollipops, frozen fruit pops and salsa. You can even add watermelon to soups, salads and other savory dishes. It's a simple, convenient way to boost your antioxidant intake and stay hydrated.
