One cup of diced watermelon (about 152 g) provides roughly 45 calories and is about 92% water, per USDA FoodData Central. Its high water content makes it a refreshing, low-calorie sweet option. It also supplies vitamin C and lycopene. Use it as a hot-weather snack or dessert swap; pair with a little protein (Greek yogurt) if you want lasting fullness.
