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.
This is for a 7 oz fruit. A medium whole grapefruit, again without sugar added has 41 calories in its 9 oz total weight. A large whole grapefruit which is almost 12 oz on average contains 53 calories altogether. 1 cup of grapefruit juice (with the sections) has a total calorie count of 74 in its 8 oz serving portion. The fruit has 9 calories per ounce and 0 per gram (too small to measure).
