The number of calories in an egg varies primarily by its size and cooking method:
- Small egg: about 54–55 calories
- Medium egg: around 63–66 calories
- Large egg: approximately 72–80 calories
- Extra-large egg: about 80 calories
- Jumbo egg: around 90 calories
Most calories come from the yolk, which contains essential vitamins and minerals
. Cooking methods affect calorie content:
- Boiled or poached eggs have roughly the same calories as raw eggs of the same size (e.g., a large boiled or poached egg has about 74–79 calories)
- Fried eggs can range from 85 to 120 calories depending on the amount and type of fat used
- Scrambled eggs with milk and butter have higher calories, roughly 170 to 245 calories for two eggs depending on preparation
In summary, a typical large egg contains about 70–80 calories, with variations depending on size and cooking method.
