Watermelon is generally considered to be a low-calorie and low-fat fruit. It is primarily composed of water, which makes it a hydrating and refreshing snack. While it does contain natural sugars, it is relatively low in calories compared to many other fruits and snacks.

On average, watermelon contains about 30 calories per 100 grams (3.5 ounces). This makes it a relatively low-calorie food. A cup of diced watermelon (approximately 150 grams) contains about 46 calories.

Moreover, watermelon is a good source of vitamins A and C, as well as other beneficial compounds like lycopene and citrulline. It is also rich in fiber, which can aid in digestion and help promote a feeling of fullness.

While watermelon is not inherently fattening, it’s important to consider your overall dietary intake and balance it with your individual calorie needs and goals. Eating watermelon in moderation as part of a well-rounded diet is generally a healthy choice.

What does 80 calories of watermelon look like?

An 80-calorie serving of watermelon would be a moderate portion, roughly equivalent to around 1 cup (about 5.6 ounces or 160 grams) of diced watermelon. This amount would fill a small bowl or be a handful of diced watermelon cubes. Remember, the exact size and weight can vary depending on the watermelon’s characteristics.

An 80-calorie serving of watermelon would be smaller than a 100-calorie serving. Here’s an approximation of what it might look like:

  • Approximately 1 to 1 1/4 cups of diced watermelon (about 6-8 ounces or 170-225 grams). This would be comparable to a small to medium-sized bowl or a moderate handful of diced watermelon cubes.
  • Alternatively, it could be around 1/10 to 1/8 of a medium-sized watermelon. This means cutting the watermelon into wedges or slices and consuming a portion that represents one-tenth to one-eighth of the entire fruit.

Again, these estimates are approximate and can vary based on the specific watermelon’s size, ripeness, and individual characteristics.

Is watermelon fattening or high in calories?

Watermelon is not considered to be fattening or high in calories. It is a low-calorie fruit that can be a part of a healthy diet. While it does contain natural sugars, watermelon is primarily composed of water and has a relatively low energy density. On average, watermelon contains about 30 calories per 100 grams (3.5 ounces). It is also a good source of vitamins, minerals, and beneficial compounds like lycopene. However, it’s important to consume watermelon in moderation as part of a balanced diet to maintain overall calorie intake and nutritional variety.

What does 100 calories of watermelon look like?

A 100-calorie serving of watermelon would be a moderate portion, approximately equivalent to around 1 1/4 to 1 1/2 cups of diced watermelon. This would fill a medium-sized bowl or be a generous handful of diced watermelon cubes. The exact size and weight can vary depending on the watermelon’s characteristics.


A 100-calorie serving of watermelon would typically look like a moderate portion. Here’s an approximation of what it might look like:

  • Approximately 1 1/4 to 1 1/2 cups of diced watermelon (about 7-8.5 ounces or 200-240 grams). This would be comparable to a medium-sized bowl or a generous handful of diced watermelon cubes.
  • Alternatively, it could be around 1/8 to 1/7 of a medium-sized watermelon. This means cutting the watermelon into wedges or slices and consuming a portion that represents one-eighth to one-seventh of the entire fruit.

Please note that these estimates are approximate and can vary based on the specific characteristics of the watermelon, such as its size, water content, and density.

How many slices are in a large watermelon?

The number of slices in a large watermelon can vary depending on the size and thickness of the slices, as well as the size of the watermelon itself. Generally, a large watermelon can yield around 20 to 30 slices.

To get a rough estimate, you can assume that each inch (2.5 cm) of the watermelon’s diameter can result in one slice. For example, if the watermelon has a diameter of 10 inches (25 cm), it may yield approximately 10 slices. However, keep in mind that this is just an approximation, and the actual number of slices can vary.

Does watermelon have a lot of sugar?

Watermelon does contain natural sugars, but it is not considered to have a high sugar content compared to many other fruits. The sweetness of watermelon comes from its natural sugars, primarily fructose. The sugar content in watermelon can vary slightly depending on factors such as the ripeness and variety of the fruit.

On average, watermelon contains about 6-9 grams of sugar per 100 grams (3.5 ounces). This is relatively low compared to fruits such as bananas, grapes, or mangoes, which can have higher sugar content.

Furthermore, watermelon is also rich in water and fiber, which can help mitigate the impact of sugar on blood sugar levels. The fiber content can slow down the absorption of sugar into the bloodstream, resulting in a more gradual release of energy.

However, if you have specific dietary concerns or health conditions related to sugar intake, it is always advisable to consult with a healthcare professional or registered dietitian for personalized guidance.

How do you measure calories in a watermelon?


The calories in a watermelon are typically determined through laboratory testing and analysis. Here’s a general overview of how calories are measured in food, including watermelon:

  1. Sample preparation: A representative sample of watermelon is selected for analysis. The sample is typically collected by taking portions from different parts of the watermelon to ensure it is representative of the entire fruit.
  2. Drying and homogenization: The water content of the sample needs to be removed to measure the calorie content accurately. The sample is dried to remove water through various methods such as freeze-drying or oven-drying. Once dried, the sample is ground or homogenized to ensure uniformity.
  3. Calorimetry: The dried and homogenized sample is analyzed using a device called a calorimeter. A calorimeter measures the amount of heat generated by burning the sample, providing an estimation of the energy content. The heat released during the combustion process is proportional to the number of calories in the sample.
  4. Calculation: The data obtained from the calorimetry is then used to calculate the calorie content of the watermelon sample. The results are usually expressed in calories per 100 grams or per serving size.
