Egg calories & macros
155 calories per 100 g · 78 calories per 1 large (50 g). Egg (cooked, hard-boiled).
One large egg is about 78 calories and 6 grams of complete protein — the reference standard against which other proteins are measured. Most of the calories and nearly all the nutrients sit in the yolk, so eating whole eggs rather than whites-only keeps the vitamins, choline, and satiety. Eggs are one of the most filling breakfast foods per calorie.

Frequently asked
How many calories in an egg?
A large hard-boiled or poached egg has about 78 calories and 6 g of protein. Frying in oil or butter adds calories from the added fat.
Are eggs good for weight loss?
Yes. Eggs are high in complete protein and among the most satiating breakfast foods, which helps people eat less over the rest of the day.
Should I eat the yolk?
For most people, yes. The yolk holds the vitamins, choline, and half the protein. Whites-only is mainly worth it when you specifically need to strip calories from a large number of eggs.
