On average, one large egg contains about 70–72 calories when boiled or poached without added fat.

However, egg calories vary depending on:

  • Egg size
  • Whether you eat the whole egg or only the white
  • Cooking method (oil, butter, milk, etc.)
  • For most diets, eggs are considered a low-calorie, high-protein food that fits well into balanced meal plans.

Calories in an Egg by Size

Here’s a quick breakdown of calories per egg by size:

Egg Size Weight Calories (Approx.)
Small 38–44 g 54–58 kcal
Medium 44–50 g 60–65 kcal
Large 50–56 g 70–78 kcal
Extra-Large 56–63 g 80–85 kcal

Most calorie calculators (including this one) use large eggs as the standard reference.

Egg White vs Egg Yolk: Calorie Breakdown

Eggs contain two nutritionally distinct parts: the egg white and the yolk.

Egg White (Albumen)

  • Calories: 15–17 kcal
  • Protein: ~3.5 g
  • Fat: 0 g

Egg whites are low in calories and fat, making them popular in low-calorie and high-protein diets.

Egg Yolk

  • Calories: 45–48 kcal
  • Fat: ~4.5 g
  • Contains: Vitamins A, D, E, choline, healthy fats

Most of an egg’s calories and nutrients come from the yolk.

Does Cooking Method Change Egg Calories?

Yes. Cooking methods can significantly affect calorie intake.

Cooking Method Calories per Egg
Boiled / Poached ~70–72 kcal
Fried (with oil) 90–120 kcal
Scrambled (milk/butter added) 90–110 kcal

To keep egg calories low, boiling or poaching is the best option.

  • Vitamin B12: Supports nerves & blood health
  • Vitamin D: Important for bones & immunity
  • Choline: Supports brain & liver function

For most healthy adults:

  • 1–2 eggs per day is generally safe
  • Some healthy individuals can consume up to 3 eggs daily
  • People with diabetes, heart disease, or high LDL cholesterol should consult a healthcare professional for personalized advice.

Moderation and preparation method matter.
