The calories you might not be counting
A whole orange is about 62 calories and comes with built-in portion control: the peel, the pith, and the chewing all slow you down. Juice removes every one of those brakes. An 8-ounce glass of orange juice has about 112 calories, zero fiber, and takes about ten seconds to drink. Most people pour 12 to 16 ounces, which is two to three oranges worth of sugar arriving with nothing to slow it. Orange chicken at a restaurant buries a few tablespoons of juice under breaded fried chicken and a sweet glaze for 400 to 500 calories a serving. Orange-flavored sports drinks and vitamin waters use the word "orange" but deliver sugar water. Forkd distinguishes between a whole orange and the juice, the glaze, and the flavored drink.
Calories by size
The USDA medium orange (2-5/8 inch, 131 g) is about 62 calories, but navel oranges at the store often run large (184 g, about 86 calories). A cup of sections is 180 g (about 85 calories). The difference between a small orange (96 g, about 45 calories) and a large one is nearly double, so "one orange" can mean different things.
| Size | Weight | Calories |
|---|---|---|
| Small (2-3/8" dia) | 96 g | 45 |
| Medium (2-5/8" dia) | 131 g | 62 |
| Large (3-1/16" dia) | 184 g | 86 |
| Cup, sections | 180 g | 85 |

Orange calories: common questions
Is an orange good for weight loss?
A medium orange is about 62 calories with 3 g of fiber and a full day of vitamin C. It is filling, low-calorie, and nutrient-dense. Where oranges cause trouble is as juice, which strips the fiber and makes it easy to drink three oranges worth of sugar in a glass.
How many calories are in a large orange?
A large orange (184 g by USDA) has about 86 calories. A small one (96 g) is about 45. Per 100 g, orange is 47 calories.
How much vitamin C is in an orange?
A medium orange has about 70 mg of vitamin C, which exceeds the daily recommended intake of 65 to 90 mg for most adults.
How many calories are in orange juice?
An 8-ounce glass of fresh orange juice has about 112 calories with no fiber. That takes roughly three oranges to produce, so the calorie density per minute of consumption is much higher than eating the fruit whole.
