For many of us, watermelons have engraved themselves in happy memories of our childhood. The thought of devouring smooth slices of this sweet, juicy, thirst-quenching summer favorite on our way back home from school or gulping down a chilled glass of watermelon juice during breakfast on a hot day immediately brings a smile to our faces. It’s funny how what used to be a guilt-free, enjoyable indulgence now receives critical skepticism, despite it being something as natural as a fruit.
“Are watermelons fattening?” is a question troubling all those keen to drop a few pounds or tone up. Most of this concern stems from the sweetness of the fruit. Since sugar is a complete no-no for the weight conscious, the doubt whether or not to eat watermelons is very relevant.
What’s In A Watermelon?
Coming as a surprise to many, watermelons are not all water. >’s what else they contain:
Watermelons Won’t Make You Gain Weight
Watermelons seem to check all the right boxes for a filler food. The following properties pf the fruit will set your weight-paranoid heart at ease:
1. Low Fat
Fat consumption has a significant influence on whether you gain weight or not. Having only 0.2% fat and 0% cholesterol, watermelons are nothing but good news to those going on low-fat diets to lose or maintain weight. Even in the list of common healthy foods of almonds, apples, and bananas, watermelons have reserved the spot for the lowest total fat content.
2. Low Calories
It is no secret that to prevent weight gain or induce weight loss, you need a calorie deficit. This means you must burn more calories than you consume. One approach is to exercise more, another is to eat fewer calories.
Quite a relief to avid calorie counters, watermelons are over 90% water and water has zero calories. A whole cup of the fruit for a meager 46 Calories is quite a healthy bargain. Even for those constantly craving sugar, this low-calorie fruit is perfect to appease a nagging sweet tooth.
In addition, drinking water has been shown to increase metabolism and bring about weight loss in obese individuals. . eating watermelons we are indirectly consuming water which is bound to reflect well on the weighing scale.
3. Low Glycemic Load
There are two values used to assess the impact a food has on blood sugar levels:
Glycemic Index (GI): GI is a measure of how high blood glucose peaks within two hours of consumption of a certain food on a scale of 0 to 100. Foods high on the GI scale (above 70) cause quick spikes in blood sugar as they release glucose quickly.
Glycemic Load (GL): GL is based on GI but takes into account portion size – how many carbs are actually present in a serving, i.e., how much you actually eat. This is why GL is the preferred index for most dieticians.
Watermelon’s glycemic index is 76 but glycemic load is only 8. You will have to eat about 10 cups to cause a spike in your blood sugar.
Watermelons have a high GI of 76, the same as that of a doughnut. However, a cup of watermelons has only 11 gm of carbs, way below the 100 gm that was used to determine its GI. You would have to eat about 10 cups for it to significantly increase your blood sugar – not something most of us would do! A cup of watermelons has a low GL of 8 (below 10 and is considered low).
While some studies show that low-GL foods help in weight loss in overweight individuals who have high insulin secretion, there is also evidence that GI and GL have nothing to do with body weight.
Watermelons May Help You Lose Weight
While watermelons keep your weight in check, they may also help reduce your weight . promoting muscle gain, reducing fat storage, enhancing your workouts, and curbing your hunger. >’s how.

A study on rats showed that a boost in dietary arginine can reduce storage of fat while increasing muscle mass. Not-so-coincidentally, this seems to be the universal goal for most of us trying to lose weight or tone. While similar results in humans are yet to be proved, we can be hopeful that watermelons may soon prove to be a convenient, effective weight loss tool that has been overlooked and underestimated up until now.

7 male athletes were given 500 ml of natural watermelon juice an hour before their workouts. The juice helped reduce the next-day muscle soreness and recovery heart rate.

- Eating Too Much Watermelon Can Cause Intestinal Discomfort
Those suffering from Crohn’s disease and intestinal bowel syndrome should steer clear of watermelons or keep their intake minimal.
Watermelons are sweet, delish, and refreshing. It is easy to get carried away and overeat them. Not only will your curbed hunger deprive you of nutrients from other foods, but you will also be exposing yourself to the laxative effects of the fruit.
Watermelons contain 7.6% carbs and are a FODMAP – which means it can cause gas bloating, and diarrhea. While this may not be a concern for stomach-strong individuals eating the fruit in moderation, it may pose a problem for those suffering from intestinal disorders like Crohn’s disease and irritable bowel syndrome.
Carbs are not the only concern. Lycopene, the pigment that imparts the red color to watermelons, may cause intestinal disturbances, too. So, while lycopene shows potential in treating cancer, heart disease, and macular degeneration, consuming large quantities of lycopene-rich foods may cause intestinal discomfort.
- Diabetics Can Eat Watermelons
Watermelons have shown beneficial effects on diabetic rats. Though clinical trials are pending, the National Institutes of Health recommends melons for diabetics as part of a balanced diet.
Watermelon’s low glycemic load also suggests it is safe diabetics can go ahead and eat the fruit in moderation. The “too much can be harmful” rule applies just as much to them as to non-diabetic individuals.
While low-calorie diets can materialize into visible short-term weight gain, it is not advisable to continue such diets for too long. The stress that inevitably builds with such diets causes an increase in stress hormone cortisol levels which is counterproductive to weight loss.
The best approach to weight loss would be to include watermelons along with other nutritious foods in your diet for sustainable results. This forms the basis of the watermelon diet that suggests substituting high-calorie foods with watermelon. It does not mean going on a crash diet of only watermelons. It is also advisable to limit yourself to 2 cups of the fruit a day.
Watermelon Fruit Or Juice?
You may choose either. Both are equally beneficial. Depending on your diet, you may eat watermelons as cubes, balls, or slices as a healthy between-meal snack, a part of a meal, or as a dessert or drink watermelon juice as a hunger-curbing refreshment throughout the day, especially before workouts. If you’re on a weight-loss spree, avoid eating watermelon seeds. Though they are nutrient-rich, a small serving of 100 gm (a little less than a cup) holds 557 Calories and 47 gm of fat.
