Calories And Carbs In One Hard-Boiled Egg: Quick Numbers
Let’s pin the baseline. A standard Large egg (about 50 g cooked) lands near 78 kcal and roughly 0.56 g of carbohydrate, with protein around 6.3 g and fat near 5.3 g. Those figures come from nutrient databases that reference USDA-sourced data for hard-boiled eggs. The carb count stays tiny across sizes because eggs don’t carry starch or fiber.
Why Size Changes The Count
Eggs are sold by size classes. A Small weighs less; a Jumbo weighs more. Calories, carbs, protein, and fat scale with weight. Cooking them in the shell doesn’t add oil or breading, so the cooking method doesn’t inflate the numbers. The only swing you’ll see comes from the egg’s size and small natural variation from hen to hen.
Early Reference Table By Size
The chart below shows typical values across sizes. Values use a Large egg as the anchor and scale by average weight per size. Real eggs vary a touch, so treat these as close estimates grounded in USDA-sourced baselines.
| Size | Calories | Carbs (g) |
|---|---|---|
| Small (~38 g) | ~54 | ~0.4 |
| Medium (~44 g) | ~63 | ~0.5 |
| Large (~50 g) | ~78 | ~0.56 |
| Extra-Large (~56 g) | ~85 | ~0.6 |
| Jumbo (~63 g) | ~96 | ~0.7 |
Planning snacks gets easier once you pin your daily calorie needs. That way, you can slot one or two eggs without overshooting your target.
What About Net Carbs?
Since fiber is essentially zero in eggs, total carbs and net carbs match. Sugars make up the tiny carb figure (~0.56 g in a Large), and that’s still a blip per serving. This is why hard-boiled eggs are popular in low-carb meal plans: you get protein and fat with minimal carbohydrate. For reference data compiled from government sources, see the MyFoodData entry for hard-boiled egg nutrition.
Protein And Fat: The Other Half Of The Picture
A Large cooked egg brings around 6–6.5 g of protein and about 5 g of fat, including roughly 1.6 g saturated. That’s a tidy macro profile for breakfast, work snacks, or a post-workout bite when you don’t want a full meal. The yolk carries most of the vitamins and minerals, while the white brings most of the protein with practically no carbs.
Choline, Vitamins, And Minerals
Eggs also supply choline, a nutrient tied to cell membranes and neurotransmitters. If you’re hunting for a deep reference, the NIH choline fact sheet lays out roles and intake ranges. You’ll also pick up B12, riboflavin, selenium, and small amounts of vitamin D. Those figures sit in the same databases that list the calories and carbs.
Portion Tips That Keep The Math Simple
One Egg
Count ~78 kcal and ~0.6 g carbohydrate for a Large. That’s your on-the-go snack or salad topper.
Two Eggs
Double it: ~156 kcal and ~1.1–1.2 g carbohydrate, plus roughly 12–13 g protein. Easy protein boost without bread or oil.
Egg Whites Only
Using whites trims fat and cholesterol but drops several micronutrients that live in the yolk. If you need a lighter macro load in a recipe, whites can help, but yolks bring flavor and fat-soluble vitamins.
How Cooking And Add-Ons Change Numbers
Boiling in the shell doesn’t add oil, so the nutrition mirrors the raw egg’s profile, adjusted for water loss. The real swing comes from what you add after cooking. A tablespoon of mayonnaise adds a wallop of calories from oil; a spoon of mustard barely moves the needle; a drizzle of olive oil piles on energy fast. Keep condiments modest if you’re watching totals.
Serving Ideas With Straightforward Macros
- Slice over leafy greens with lemon juice and herbs.
- Chop with a spoon of Greek yogurt, mustard, and chopped celery.
- Pair with raw veggies and a little salt and pepper.
Authoritative Numbers You Can Trust
Nutrition panels in this guide reference datasets used by dietitians and researchers. The hard-boiled entry in MyFoodData cites the same U.S. database many apps pull from, listing 78 kcal and ~0.56 g carbohydrate for a Large egg. Broader eating pattern advice lives in the federal Dietary Guidelines, which frame eggs inside full-day meals.
| Nutrient | Amount | Notes |
|---|---|---|
| Calories | ~78 kcal | Per whole egg, cooked. |
| Carbohydrate | ~0.56 g | No fiber; tiny sugars only. |
| Protein | ~6.3 g | White carries most. |
| Total Fat | ~5.3 g | Includes ~1.6 g saturated. |
| Cholesterol | ~186 mg | Lives in the yolk. |
| Sodium | ~62 mg | Before any seasoning. |
| Vitamin B12 | ~0.56 mcg | About one-quarter of daily value. |
| Riboflavin (B2) | ~0.26 mg | Solid contribution. |
| Selenium | ~15 mcg | Roughly one-quarter DV. |
| Vitamin D | ~1.1 mcg | Small boost from the yolk. |
Label-Style Facts In Everyday Meals
Salad Bowl Math
Two chopped eggs add about 156 kcal, ~1.1 g carbs, and ~12 g protein before dressings. Add leafy greens and vinegar for volume without big calorie costs.
Snack Box Plan
Pair one egg with sliced cucumber and a handful of berries. You keep carbs low from the egg while the fruit adds a bit of natural sweetness.
Breakfast Sandwich Swap
Use a whole-grain English muffin and sliced egg with tomato and arugula. Keep sauces light to avoid extra oil. That keeps the math predictable.
Frequently Raised Points, Answered Briefly
Do Carbs Increase With Longer Boil Times?
No. Cook time affects texture, not carbohydrate content. The carbs stay near a half gram per Large egg.
Is A Hard-Boiled Egg Keto-Friendly?
Yes. The carb load is tiny, so it fits most low-carb plans. Watch toppings like mayo or oils, which boost calories quickly.
Where Do The Numbers Come From?
Most nutrition labels for eggs trace back to federal nutrient databases. The widely used hard-boiled listing shows ~78 kcal and ~0.56 g carbohydrate for a Large egg, consistent across sources that cite the same dataset.
Smart Ways To Use Eggs In A Balanced Day
Think in patterns. An egg or two at breakfast pairs well with fruit and whole grains. At lunch, add one to greens and beans. At dinner, turn them into a quick curry or stir-fry with veggies. That spreads protein through the day and keeps carbs where you want them.
Bottom Line On Calories And Carbs
A cooked Large egg sits at ~78 calories with around half a gram of carbohydrate. Sizes above or below move the counts in step with weight. Keep condiments modest if you’re watching totals, and shape your meal plan around the broader guidance laid out in the federal eating pattern materials.
