One large boiled egg has about 78 calories; size and serving (white vs yolk) shift the count.

Boiled Egg Calories By Size And Serving
Calorie counts sit in a tight range, but they do change with egg size and which parts you eat. A typical large hard-cooked egg lands near 78 kcal with roughly 6 g protein and about 5 g fat. Eat only the white and you drop to around 17 kcal, while a yolk alone sits near 55 kcal. Those figures come from national nutrient datasets that labs update on a routine schedule, which keeps the numbers steady and reproducible across kitchens and brands.
| Portion | Calories (kcal) | Protein (g) |
|---|---|---|
| 1 large whole egg (hard-cooked) | ~78 | ~6.3 |
| 2 large whole eggs | ~156 | ~12.6 |
| 1 egg white (from 1 large) | ~17 | ~3.6 |
| 1 egg yolk (from 1 large) | ~55 | ~2.7 |
| 1 medium whole egg | ~65–72 | ~5–6 |
| 1 extra-large whole egg | ~80–85 | ~6–7 |
| 1 jumbo whole egg | ~90–100 | ~7–8 |
If you log food or plan meals, anchoring portions to a fixed size keeps tracking simple. Once you set your daily calorie needs, swapping one whole egg for two whites trims calories while keeping a decent protein hit. On the flip side, doubling whole eggs moves you toward a small entrée in both energy and fullness.
What Drives The Number Up Or Down
Size And Edible Portion
Egg cartons list sizes by weight class. Larger eggs contain more white and a slightly larger yolk, so energy creeps up with each step. If your carton mixes sizes, weigh a peeled egg once; from there, your eyes get better at guessing portions.
White-Only, Yolk-Only, Or Whole
Most calories, fat, and cholesterol live in the yolk. The white is lean protein with trace carbs. That’s why a white clocks 17 kcal while a yolk sits near 55 kcal per large egg. If you enjoy the taste and texture of the yolk but want to keep energy modest, try one whole egg plus extra whites in salads or rice bowls.
Cooking And Add-Ons
Cooking an egg in the shell doesn’t add energy. The count changes when you bring oil, mayo, butter, or sauces to the party. A small swipe of mayonnaise can add 90–100 kcal per tablespoon; a drizzle of olive oil adds around the same. Spices, mustard, vinegar, and herbs keep the taste bright without moving the number much.
Macronutrients, Micronutrients, And Satiety
Protein That Pulls Its Weight
Egg protein has a strong amino acid profile. One large hard-cooked egg brings a little over 6 g, enough to round out a light snack or to lift the protein content of toast, noodles, or a grain bowl. Whites alone bring about 3.6 g per egg, handy for volume without a big calorie bump.
Fats You Can See In The Numbers
Most of the egg’s fat sits in the yolk—roughly 5 g in a large whole egg. Hard-cooking doesn’t change the mix, and there’s very little carbohydrate either way. If you’re keeping energy tight, pair your egg with high-water foods like cucumber, tomatoes, or berries. The plate looks full while the tally stays tidy.
Choline, Selenium, And Friends
Eggs supply choline, a nutrient tied to cell membranes and methyl-group metabolism. That’s one reason many dietitians like an egg or two in a mixed, plant-forward plate. For a deep dive into choline’s roles across tissues, the NIH health-professional fact sheet outlines research and daily intake ranges.
Serving Ideas That Keep The Count Honest
Under-200-Calorie Pairings
- 1 whole egg + sliced cucumbers and cherry tomatoes
- 1 whole egg + 1 extra white over mixed greens with lemon
- 1 whole egg + orange or a small apple
Meal Prep, No Guesswork
Cook a batch, chill, and stash them in the shell. Label a container with the cook date. Peel right before eating for best texture. If you prep lunches, two whites plus one whole egg turns a side salad into something that satisfies without tipping your calorie budget.
Health Context: Cholesterol And Frequency
Dietary cholesterol clusters in the yolk. Broad guidance points to keeping saturated fat low and watching total dietary cholesterol if you have targets from your care team. For a current lay summary of where eggs fit in a heart-smart pattern, the American Heart Association reviews diet context and notes roughly 200 mg cholesterol in a large egg yolk, with advice shaped by the rest of your plate and personal risk factors (AHA cholesterol overview).
Portion Math You’ll Use Every Week
Quick Rules You Can Apply
- One large hard-cooked egg ≈ 78 kcal, ~6 g protein.
- Two large eggs ≈ 156 kcal, ~12 g protein.
- One egg white ≈ 17 kcal; yolk ≈ 55 kcal.
- Size up or down by 5–20 kcal as eggs move from medium to jumbo.
Swap Ideas To Hit Targets
Want more protein with minimal energy? Keep the first egg whole for taste, add a second as a white. Need more calories for a long run? Pair two whole eggs with whole-grain toast and fruit. When cutting, choose vinegar-based dressings and spices instead of mayo-heavy mixes.
| Add-On Or Prep | Typical Amount | Extra Calories (kcal) |
|---|---|---|
| Mayonnaise (standard) | 1 Tbsp (14 g) | ~90–100 |
| Greek yogurt (plain, 2%) | 2 Tbsp (30 g) | ~25–30 |
| Olive oil drizzle | 1 tsp (5 g) | ~40–45 |
| Mustard | 1 tsp | ~5 |
| Everything bagel seasoning | 1 tsp | ~5 |
| Hot sauce | 1 tsp | ~0–5 |
Storage, Safety, And Timing
How Long They Keep
Hard-cooked eggs keep up to a week in the fridge when chilled soon after cooking. Store them in a covered container. If you peel ahead, keep them in water and change the water daily, or use a sealed box lined with a damp paper towel.
Easy-Peel Method
Use older eggs when you can. Cook in simmering water for 9–12 minutes based on size, then ice-bath for at least 5 minutes. Crack the wider end first and peel under a thin stream of water for clean sheets of shell.
Sample Day With Eggs, Different Goals
Weight Loss Or Tight Budgeting
One whole egg plus two whites at breakfast sits near 112 kcal but still packs about 13 g of protein. That combo eases hunger, and you can save calories for later meals. If you need more structure over the week, our calorie deficit guide lays out the math and simple swaps.
Maintenance Or Active Days
Two whole eggs with toast and fruit creates a tidy 350–450 kcal breakfast depending on bread and fruit choices. The protein bridges the morning and allows a later lunch without energy dips.
High-Protein Snack Ideas
- Egg slices over avocado rice cakes
- Chopped eggs with pickles and mustard
- Egg halves dusted with smoked paprika
Why Calories From Eggs Feel Different
Protein and water content raise satiety per calorie. You chew more than you would with a drink or a bar, and the texture slows bites. That’s why a small number like 78 kcal often eats bigger than it looks on paper.
Method Notes And Sources
The calorie and macro figures used here align with government nutrient datasets for “hard-boiled egg, 1 large” and common egg parts. For a detailed nutrient line per portion and cooking style, see the Health Canada table for eggs and egg dishes (hard-boiled shows 78 kcal for a large egg) and the USDA FoodData Central landing page that underpins many public nutrition tools.
