Both pink and red grapefruit are a bit higher in calories than white grapefruit. One whole pink or red grapefruit, raw, has about 104 calories, while one whole white grapefruit, raw, has about 78, according to the USDA National Nutrient Database. These calorie counts are for a medium grapefruit.
But exactly how much juice is in a grapefruit anyway? And how many sections are in a grapefruit? In order to figure out how much juice and sections are in a grapefruit we selected a medium grapefruit, measuring about 5 inches (12.5 cm) wide and weighing a generous 1 pound for our test sample. On average, you can squeeze 1 cup of juice from 1 grapefruit and will find 12 fruit sections. Although used less often than an orange, lemon or lime, 1 grapefruit gives about 3 tablespoons of zest.
