How many calories in an egg? A medium boiled egg has about 78 calories. That number goes up or down with the size of the egg and, above all, the way you cook it.
The gap is not small. The same egg can hold 78 or 110 calories depending on what hits the pan along with it.
This guide shows the count by cooking method, how much protein an egg delivers, what changes between white and yolk, and settles once and for all whether eggs are fattening.
Calories in an egg: boiled, fried, scrambled, and poached
An egg holds from 78 to about 120 calories depending on the method: boiled and poached stay near 78 kcal, while fried and scrambled climb because they pick up fat on the way.
| Method | Calories (1 egg) | Why |
|---|---|---|
| Boiled | ~78 kcal | No added fat |
| Poached | ~78 kcal | Cooked in water, no fat |
| Fried | 90 to 110 kcal | The egg soaks up part of the oil or butter |
| Scrambled | 90 to 120 kcal | Depends on the butter, oil, or milk used |
| Omelet (2 eggs) | 180 to 240 kcal | Two eggs plus the cooking fat and any fillings |
The egg itself barely changes. What changes is the invisible add-on: the spoon of oil, the slice of butter, the milk in the scramble. That is why the same unit shows up with such different numbers.
Why the cooking method changes the count so much
The method changes an egg's calories because the fat used to cook it is the most calorie-dense ingredient on the plate, and the egg absorbs part of it.
Every gram of fat carries 9 calories, more than double protein or carbs. One teaspoon of oil already adds about 40 calories to the dish.
With a boiled or poached egg that never happens, because water adds no calories. With a fried or scrambled egg, the final number is the egg plus whatever you put in the pan.

How much protein an egg has
An egg has about 6 grams of complete protein, with every essential amino acid and high absorption by the body.
That protein does not change with the method. Boiled, fried, or scrambled, the egg still delivers the same 6 grams. Only the fat around it changes.
It is one of the best protein-per-calorie ratios out there, and a cheap one. To see how the egg compares to other sources, the high protein foods guide lays it out.
White or yolk: where everything sits
The white holds the protein with almost no calories, and the yolk holds the calories, the fat, and most of the vitamins and minerals.
| Criteria | White | Yolk |
|---|---|---|
| Calories | ~17 kcal | ~55 kcal |
| Protein | A little over half the total | A little under half the total |
| Fat | Almost none | Holds all the egg's fat |
| Vitamins and minerals | Few | Vitamins A, D, E, B12, iron, and choline |
Eating only the white makes sense when the goal is pure protein with minimal calories. But tossing the yolk throws away the most nutritious part of the egg. The right call usually depends on your daily calorie deficit and the rest of your plate.
Are eggs fattening?
An egg does not make you gain weight on its own. No single food does: what raises weight is the day's total calories sitting above what your body burns.
If anything, the egg works in favor of anyone trying to lose weight. It fills you up for few calories, which helps you eat less the rest of the day without going hungry.
What decides the result is not cutting the egg, it is closing the day in a calorie deficit. Inside a balanced count, the egg fits easily, fried included, as long as you count the cooking fat.
How many eggs you can eat per day
For most healthy people, eating one to two eggs a day is safe, and recent research shows the cholesterol in eggs affects blood cholesterol less than once believed.
The old rule of one egg a week at most is behind us. Today's guidance looks at the whole eating pattern, not one food in isolation, as the Harvard T.H. Chan School of Public Health notes.
⚠️ When to check with a doctor: anyone with diabetes, genetically high cholesterol, or heart disease should set their egg amount with a doctor or dietitian. This content is informational and does not replace individual guidance.
How to fit the egg into your diet
The egg fits any goal: it works at breakfast, as a snack, and at dinner, and serves both weight loss and muscle gain.
At breakfast, it fixes the weak point of most routines, which is starting the day on carbs alone. The easiest way to keep it consistent is to slot it into a healthy meal plan for the week.
ContaCal is the photo calorie counter app, and it recognizes the egg the way you cooked it, adding the fat from frying or scrambling without you typing a thing.
