During the summer, people often find themselves surrounded by an array of tempting food choices like ice cream and slushies. Managing weight becomes a struggle amidst these delicious yet high-calorie options. However, there’s a refreshing, tasty and healthy alternative that often gets overlooked — watermelon! This article explores the nutritional value of watermelon, its hydration benefits, its role in curbing appetite, its impact on metabolism and how it fits into a healthy diet.
Keep reading to discover the wonders of watermelon for weight management.
Nutritional profile of watermelon
This fruit stands as a nutritional powerhouse. We’ll uncover its high water content, low-calorie nature, as well as its vitamins, minerals, and antioxidants.
Hydration — high in water
The name “watermelon” says it all — it’s made up of about 92% water, making it not just delicious but also incredibly refreshing for hot summer days to fight the thirst.1
Two-thirds of our bodies are made up of water!2 It’s crucial to stay hydrated throughout the day by drinking fluids frequently. As mentioned earlier, adding watermelon to our diet for its high water content can help with this.
Staying hydrated helps our body work well and burn fat. When we’re hydrated, our metabolism stays healthy, and we can tell the difference between thirst and hunger, so we don’t eat too much.
Nutritional facts
In a cup of watermelon, you’ll discover zero fat, cholesterol, or sodium alongside its nutritional content: 46 calories, 12 grams of carbohydrates, 865 IU of vitamin A, 12 milligrams of vitamin C, 170 milligrams of potassium, and 0.1 milligrams of vitamin B6.1
| Label | Nutritional content values |
| Calories | 46 |
| Carbohydrates | 12 g |
| Vitamin A | 865 IU |
| Vitamin C | 12 mg |
| Vitamin B6 | 0.1 mg |
| Potassium | 170 mg |
This makes watermelon a highly healthy alternative to many sweets because of its low-calorie content and numerous nutritional benefits. For example, compare it to a 100-gram serving of doughnuts, which has way more calories, carbohydrates, fat, and less protein with 450 calories, 51 grams of carbohydrates, 25 grams of fat, and 4.9 grams of protein, we can see a substantial difference in numbers.3
Low glycemic index
When managing diabetes, selecting suitable foods becomes a challenge due to their potential impact on blood sugar levels. Opting for low glycemic index foods — indicating how quickly a food raises blood sugar — is recommended over high glycemic options. The glycemic index essentially measures how a particular food affects blood glucose levels after consumption. In this context, watermelon stands out as an excellent choice for individuals, diabetic or not.4
Its low glycemic index ensures minimal spikes in blood sugar levels, making it a suitable addition to their daily dietary routine without causing significant fluctuations. This indicates that when you consume watermelon, it releases less glucose into your bloodstream compared to many other foods. Hence, enjoying a slice won’t lead to a substantial increase in blood sugar levels.4
Weight management
Weight management is something lots of people care about. To reach a good weight, it takes dedication, commitment, and knowing a lot about food, exercise, and how many calories we need. Whether we want to stay the same weight or lose a bit, there are things we can change in our everyday life, like what we eat for snacks and meals, and when we choose to eat or not eat, that can make a big difference.
Calories
To start, it’s essential to grasp the concept of calories and how they vary across different foods. Take, for instance, the contrast between watermelon and doughnuts — a simple example mentioned above.
Your body burns calories, and here are three situations:
- If you want to lose weight, you need to burn more calories than your body requires. That means doing things that make your body work more and use up those calories5
- If you want to stay the same weight, you should eat the same number of calories that your body needs. It’s like keeping things balanced, not too much and not too little5
- Now, if you want to gain weight, you need to eat more than what your body needs. This means having extra food to give your body more energy and calories than it uses up5
Each step breaks down how your body handles calories differently based on your goals for weight. For instance, an average man typically requires around 2,500 kcal daily, while an average woman needs about 2,000 kcal per day.4 However, these numbers might vary depending on factors such as your age, weight, height, the amount of exercise you engage in, and the goal you want to achieve.5
Diet
Eating a nutritious diet involves having well-balanced meals throughout the day, aligning with specific goals like gaining, losing, or maintaining weight. This includes five key meals: breakfast, snack 1, lunch, snack 2, and dinner. Consistency in meal timings and distributing calories evenly among these meals plays a significant role in reaching your desired goal.
Watermelons serve a crucial role as snacks, offering a healthy substitute for common snacks like chips or cookies. Additionally, they can complement main meals, as we’ll discuss specific recipes later in this article. As a refreshing summer snack, watermelons can effectively replace ice cream due to their high hydration content. This hydration not only refreshes but also energises, aiding in enduring the summer heat while providing a satisfying feeling.
Watermelon study
In a study conducted in 2019, involving 33 individuals categorised as overweight or having obesity, participants who consumed watermelon regularly for four weeks instead of opting for low-fat cookies reported decreased feelings of hunger and reduced cravings to eat.6
