A large egg contains about 72 calories. That figure comes from the USDA’s FoodData Central database, and it applies to one large egg eaten whole — both the white and the yolk. The yolk carries roughly 55 of those calories, while the white accounts for about 17. If you are tracking calories for weight management or just want to know what is on your plate, 72 is the number to remember for a large egg.
Eggs are one of the few foods where the calorie count is genuinely simple. No brand variation, no added ingredients, no label math. One large egg, one number. What gets more complicated is everything around that number — how cooking changes it, why egg size matters more than most people think, and whether the cholesterol in the yolk should affect how often you eat them.
How Many Calories Are In A Large Egg?
A large egg provides approximately 72 calories. The USDA defines a large egg as weighing about 50 grams without the shell. That works out to roughly 1.4 calories per gram of egg.
The calorie split between yolk and white is not even. The yolk contains about 55 calories and the white about 17. That means the yolk holds roughly three-quarters of the total calories, along with nearly all of the fat and cholesterol. The white is mostly water and protein, which is why it is so low in calories.
Egg size matters more than most people realize. Here is how the standard USDA sizes compare:
| Egg Size | Approximate Calories | Typical Weight (without shell) |
|---|---|---|
| Small | ~54 | 38 g |
| Medium | ~63 | 44 g |
| Large | ~72 | 50 g |
| Extra Large | ~80 | 56 g |
| Jumbo | ~90 | 63 g |
Most recipes in the US are written for large eggs. If you swap in medium or extra large without adjusting, you shift the calorie total by 9 to 18 calories per egg. That adds up across a batch of baked goods or a week of breakfasts.
Does Cooking Change The Calories In An Egg?
Cooking does not change the calories in the egg itself. A boiled egg, a poached egg, and a scrambled egg all start with the same 72 calories for a large egg. Heat alters protein structure and water content, but it does not create or destroy calories.
What changes the number is what you add. Butter, oil, cheese, cream, and sauces can multiply the calorie count quickly. A large egg scrambled in one tablespoon of butter adds roughly 100 calories — more than doubling the total. A fried egg cooked in oil absorbs some of that oil, and the amount depends on temperature, pan type, and how long it cooks.
Hard-boiled eggs are the clearest case. No added fat, no absorption, no variables. One large hard-boiled egg is 72 calories. That makes them one of the most predictable protein sources available.
Egg whites cooked alone are also straightforward. Three large egg whites contain about 51 calories and roughly 11 grams of protein, with almost no fat. Some people use this as a way to get protein with fewer calories, though they lose the nutrients concentrated in the yolk.
What Nutrients Come With Those 72 Calories?
A large egg delivers about 6 grams of protein, 5 grams of fat, and less than 1 gram of carbohydrate. The protein is complete, meaning it contains all nine essential amino acids in proportions the body can use efficiently. Egg protein is often used as a reference standard when researchers compare protein quality across different foods.
The yolk carries most of the micronutrients. A large egg provides meaningful amounts of vitamin D, vitamin B12, riboflavin, folate, and selenium. It also contains choline, a nutrient involved in cell membrane structure and neurotransmitter function. Choline intake is often below recommended levels in the US, and eggs are one of the richest common food sources.
Two carotenoids — lutein and zeaxanthin — are also concentrated in the yolk. These pigments accumulate in the retina and are associated with eye health. The evidence for their role in reducing age-related eye disease comes mostly from observational studies and some clinical trials, and it is stronger for supplements than for eggs specifically. Still, eggs are a legitimate dietary source.
One detail that surprises people: the color of the yolk does not indicate nutrient content. A deep orange yolk and a pale yellow yolk from hens of the same diet differ mainly in what the hen ate, not in how nutritious the egg is for you. Pasture-raised hens often produce darker yolks because of carotenoids in their feed, but the calorie and protein content stays close to the same.
Are Eggs Bad For Your Cholesterol?
For most people, dietary cholesterol from eggs has a smaller effect on blood cholesterol than once believed. The liver produces most of the cholesterol circulating in your blood, and for many people, eating cholesterol triggers a compensatory drop in the liver’s own production.
This does not mean eggs have no effect. Some people are hyper-responders — they absorb more dietary cholesterol and see a larger rise in blood cholesterol when they eat eggs. The proportion of the population that falls into this category is debated, and there is no simple test to identify them in routine practice.
Major health organizations have moved away from strict daily cholesterol limits for the general population. The 2015–2020 Dietary Guidelines for Americans removed the specific 300 mg per day cholesterol limit that had been in place, though it still advised eating as little dietary cholesterol as possible. Current guidance generally emphasizes overall dietary patterns rather than singling out eggs.
For people with diabetes or existing heart disease, the picture is less clear. Some studies have found associations between higher egg intake and cardiovascular risk in these groups, while others have not. The evidence is mixed. If you have a condition that affects cholesterol metabolism, that is a conversation to have with your doctor rather than something to resolve from a general article.
How Do Eggs Fit Into A Daily Calorie Budget?
At 72 calories, a large egg is a low-calorie food relative to its protein content. Six grams of protein for 72 calories works out to about 12 calories per gram of protein. That is a favorable ratio compared to many other protein sources.
For context, here is how a large egg compares to a few common breakfast proteins:
- One large egg: ~72 calories, ~6 g protein
- One ounce of cooked chicken breast: ~46 calories, ~9 g protein
- One tablespoon of peanut butter: ~94 calories, ~4 g protein
- One cup of plain Greek yogurt (nonfat): ~100 calories, ~17 g protein
Eggs are not the most protein-dense food per calorie, but they are convenient, inexpensive, and easy to prepare without added fat. A two-egg breakfast is about 144 calories before anything else goes in the pan.
Where the calorie math gets tricky is at restaurants. A diner omelet with cheese, ham, and oil can easily reach 600 to 800 calories. The eggs themselves contribute a small fraction. The same is true for egg salad, which is mostly mayonnaise by volume in many recipes.
If you are watching calories, the preparation method matters far more than the egg itself. Boiled, poached, or cooked in a nonstick pan with no added fat keeps the number close to 72. Fried in butter or oil, or folded into a cheesy scramble, the egg becomes a minor player in its own calorie count.
Do Brown Eggs Have More Calories Than White Eggs?
Brown eggs and white eggs have the same number of calories. The shell color is determined by the breed of the hen, not by nutrition. A large brown egg and a large white egg both contain roughly 72 calories and the same macronutrient profile.
The same is true for other shell variations. Blue and green eggs, laid by certain heritage breeds, do not differ nutritionally from white or brown eggs in any meaningful way.
The persistent belief that brown eggs are healthier likely comes from their higher price at the grocery store. Brown eggs often cost more because the hens that lay them tend to be larger and eat more feed, not because the eggs are more nutritious. Price and nutrition are not linked here.
What does affect the nutritional profile of an egg is the hen’s diet. Hens fed diets enriched with omega-3 fatty acids produce eggs with higher omega-3 content. These are sometimes sold as omega-3 eggs. The calorie count stays close to the same, but the fat composition shifts. Whether that shift produces meaningful health benefits compared to eating fish or taking a supplement is not well established.
Frequently Asked Questions
How many calories are in a large egg white?
A large egg white contains about 17 calories. The yolk accounts for the remaining roughly 55 calories in a whole large egg.
How many calories are in two large eggs?
Two large eggs contain about 144 calories. That total assumes no butter, oil, or other ingredients are added during cooking.
Are hard-boiled eggs lower in calories than scrambled eggs?
A hard-boiled egg and a plain scrambled egg contain the same 72 calories for a large egg. Scrambled eggs often end up higher because of the butter or oil used in the pan.
How many calories are in a large egg without the yolk?
A large egg white alone has about 17 calories. Removing the yolk eliminates nearly all the fat and cholesterol along with roughly three-quarters of the calories.
