The calories you might not be counting
Boiling is the one cooking method that adds nothing to the egg. That is what makes a boiled egg a reliable 78 calories. The count drifts when the egg lands on something else. Deviled eggs whip the yolk with mayo and mustard, pushing each half to 60 to 80 calories and the whole egg past 140. Egg salad folds mayo through chopped eggs until the dressing outweighs the protein: a half-cup serving can reach 250 to 350 calories. A Cobb salad lists a boiled egg in the name but buries it under bacon, cheese, avocado, and blue-cheese dressing for a 700-calorie bowl. Even a simple ramen egg marinates in soy, mirin, and sugar. Forkd tracks the egg and the mayo or dressing as separate items so the 78-calorie base does not absorb the toppings.
Calories by size
One large hard-boiled egg is 50 g, about 78 calories. A cup of chopped hard-boiled egg is 136 g (about 211 calories), which is roughly 2.7 eggs. Most meal-prep containers hold two eggs (about 155 calories), a compact protein hit with no cooking fat to account for.
| Size | Weight | Calories |
|---|---|---|
| Large egg | 50 g | 78 |
| Cup, chopped | 136 g | 211 |
Scanning a boiled egg with Forkd catches the exact portion and the hidden extras this page just described, the oil, the dressing, the topping a photo alone would miss.
Boiled Egg calories: common questions
How many calories are in one boiled egg?
One large hard-boiled egg (50 g) has about 78 calories, with 6.3 g of protein and 5.3 g of fat. No oil or butter is involved, so the count is just the egg.
Are boiled eggs good for weight loss?
Boiled eggs are one of the most protein-dense low-calorie foods: 78 calories and 6.3 g of protein per egg, with no added fat from cooking. Two eggs at 155 calories make a filling snack or meal addition.
Is a boiled egg healthier than a fried egg?
The egg itself is nutritionally the same. The difference is the cooking fat. A fried egg picks up 40 to 100 calories from the oil or butter in the pan. A boiled egg stays at 78 because the water adds nothing.
