Boiled egg whites provide about 12 grams of complete protein per 100 grams, with roughly 52 calories and almost no fat or cholesterol.
Boiled egg whites sit in a sweet spot for many eaters: plenty of protein, hardly any calories, and no cholesterol from the yolk. When you know the exact protein in a 100 gram portion, you can plan breakfast bowls, salads, and macro targets with far more confidence.
The figures in this article come from nutrient databases built on laboratory analysis of eggs, then adjusted for cooking. That means the boiled egg white numbers you see here line up closely with data from government and research sources, not guesswork or brand labels.
Boiled Egg White Protein Per 100G: Basic Nutrition Breakdown
The headline number many people care about is simple: boiled egg white protein per 100g sits around 12 grams. Raw egg whites land near 10.9 grams of protein and 52 calories per 100 grams, and boiling them concentrates the protein slightly as a bit of water leaves the white during cooking.
To make the numbers easier to use, picture a kitchen scale. Place chopped boiled egg whites on it until you reach 100 grams. That mound of cooked whites will give you roughly 12 grams of complete protein with barely any fat, only a trace of carbohydrate, and a modest amount of sodium and minerals.
| Nutrient | Amount Per 100 g | Notes |
|---|---|---|
| Energy | ≈ 52 kcal | Low calorie load for the volume of food |
| Protein | ≈ 12.0 g | Complete protein with all indispensable amino acids |
| Total Fat | ≈ 0.2–0.3 g | Almost fat free once the yolk is removed |
| Carbohydrate | ≈ 0.5–0.7 g | Only trace carbohydrate |
| Water | ≈ 87 g | High water content helps with meal volume |
| Sodium | ≈ 160–170 mg | Native sodium before any added salt |
| Potassium | ≈ 160 mg | Modest contribution to daily potassium intake |
| Riboflavin (B2) | ≈ 0.4 mg | Egg whites are a handy riboflavin source |
| Selenium | Small amount | Adds to total selenium across the day |
Those values give a clear picture of why boiled egg whites show up so often in meal plans. A 100 gram portion adds a noticeable chunk of protein with little energy cost, so you can pair it with whole eggs, oats, rice, vegetables, or fruit without blowing your calorie budget.
How Boiling Changes Egg White Nutrition
When you boil an egg, the proteins in the white uncurl and set. The amount of protein stays almost the same, but the texture shifts from runny to firm. Water loss during cooking is small, so boiled egg white protein per 100g ends up only slightly higher than the raw number.
The main difference is digestibility. Heat makes egg white protein easier to digest than raw egg white, which is why cooked eggs deliver more usable amino acids to your muscles and other tissues than a glass of raw whites.
Why Egg White Protein Fits Muscle And Weight Goals
Egg white protein is often described as a reference protein for scoring other protein sources. It contains all the indispensable amino acids in a pattern that matches human needs, and the body absorbs it efficiently. That makes boiled egg whites handy for muscle repair and growth.
Complete Protein In A Lean Package
Every 100 grams of boiled egg whites bring roughly 12 grams of protein with hardly any fat or carbohydrate. That ratio stands out when you compare it to many meats or dairy foods, which often bring more fat or sugar along with their protein.
This lean profile helps if you are trying to add protein without raising total calories too much. You can keep your total fat intake in line by leaning on boiled egg whites while still enjoying some whole eggs, oily fish, nuts, or plant oils for fat-soluble vitamins and flavor.
Satiety, Blood Sugar, And Meal Timing
Protein slows digestion and steadies blood sugar swings, which helps many people feel full for longer after a meal. Boiled egg whites are easy to slot into breakfast or a post-workout plate, since they reheat well and pair with both sweet and savory ingredients.
If you spread protein across the day, rather than loading nearly all of it at dinner, you give your body repeated opportunities to build and maintain lean tissue. A 100 gram portion of boiled egg whites can anchor a snack or add a boost to meals that are otherwise rich in starch or fruit.
Boiled Egg Whites Vs Whole Eggs And Other Proteins
Whole eggs bring a different mix of nutrients from boiled egg whites alone. The yolk carries more protein per gram than the white, along with choline, vitamin A, vitamin D, vitamin B12, and many other micronutrients. The trade-off is cholesterol and a higher fat and calorie load for each 100 gram portion.
For that reason, many people combine the two: a couple of whole eggs for vitamins and flavor, plus extra boiled egg whites for lean protein. That blend keeps breakfast satisfying without sending calories through the roof.
How Boiled Egg White Protein Per 100G Compares To A Single Egg
A typical large egg white weighs around 33 grams. Three large boiled egg whites land close to 100 grams and contain about 11–12 grams of protein. A large whole boiled egg weighs roughly 50 grams and delivers around 6–7 grams of protein, but with more fat and cholesterol than the same weight of egg white.
Protein Per 100G Across Common Foods
It helps to see boiled egg whites next to other familiar foods. The figures below are rounded and based on cooked, ready-to-eat portions where possible.
| Food (100 g) | Protein (g) | Calories (kcal) |
|---|---|---|
| Boiled egg white | ≈ 12 g | ≈ 52 kcal |
| Whole hard-boiled egg | ≈ 12–13 g | ≈ 155 kcal |
| Skinless chicken breast | ≈ 31 g | ≈ 165 kcal |
| Firm tofu | ≈ 17 g | ≈ 144 kcal |
| Cooked lentils | ≈ 9 g | ≈ 116 kcal |
| Greek yogurt, plain | ≈ 10 g | ≈ 60–70 kcal |
| Cottage cheese, low-fat | ≈ 11–12 g | ≈ 80–90 kcal |
| Whey protein powder | ≈ 70–80 g | ≈ 400 kcal |
Boiled egg whites land in the same protein range as some dairy staples but stay strict on calories and fat. They sit far below chicken breast or whey powder on a per-100 gram basis, yet those options are more concentrated and not always as easy to fit into simple meals.
If you like eggs and want a leaner plate, boiled egg whites give you a way to tilt the energy-to-protein ratio in your favor while still using the same carton of eggs already in your fridge.
How Much Boiled Egg White Protein Fits Your Day
Most healthy adults are guided toward at least 0.8 grams of protein per kilogram of body weight each day, with active people often aiming higher. That means a 70 kilogram person might target somewhere between 56 grams and 90 grams of protein, depending on training, age, and health status.
Because 100 grams of boiled egg whites bring about 12 grams of protein, that same person would meet roughly one fifth of their day’s basic protein target with a single 100 gram serving. The rest can come from whole eggs, meat, fish, dairy, beans, soy foods, grains, nuts, and seeds.
Simple Math For Real Portions
Here is one way to think through the numbers using a 70 kilogram adult who wants about 80 grams of protein in the day:
- Breakfast: 100 g boiled egg whites (≈ 12 g) plus one whole egg (≈ 6–7 g) gives around 18–19 g total.
- Lunch: 100 g cooked chicken breast adds about 31 g.
- Dinner: 150 g cooked lentils add around 13–14 g.
- Snacks: 150 g Greek yogurt contributes about 15 g.
In that simple layout, boiled egg white protein per 100g handles only a slice of the total, yet it lets you shift calories away from fat if you need room for sauces, oils, or other foods you enjoy.
If you follow a vegetarian plan that still includes eggs, boiled egg whites can fill gaps on days when beans, lentils, or tofu fall a little short of your protein target.
Practical Tips For Cooking, Weighing, And Storing Egg Whites
Turning whole eggs into a consistent 100 gram portion of boiled whites takes a bit of routine, but once you have a system it becomes easy to repeat each week.
Preparing Boiled Egg Whites For Meal Prep
Start by boiling a batch of whole eggs in the shell. Cool them in cold water, peel, then slice the eggs and gently pop the yolks out. You can keep the yolks for spreads or mix a few back into your meals when you want extra vitamins and flavor.
Chop the remaining whites into even pieces, then weigh them in a bowl. Each set of roughly three large whites will come close to 100 grams. You can divide that bowl into boxes or jars, label them with the weight, and know exactly how much protein you are adding each time.
How To Weigh 100 Grams Without A Scale
If you do not own a scale, you can still estimate. Three large boiled egg whites piled on a small plate come close to 100 grams. Four medium whites or about six small whites will land in the same ballpark. The exact number shifts with egg size, but for everyday tracking this rule of thumb works well.
Serving Ideas That Keep Things Interesting
- Dice boiled egg whites into a grain bowl with rice, roasted vegetables, and a drizzle of olive oil.
- Stir chopped whites into tomato-based soups just before serving for an extra protein lift.
- Fold sliced egg whites into whole-egg omelettes to raise protein without piling on fat.
- Mix boiled whites with herbs, yogurt, and mustard for a lighter egg salad to spoon over toast or potatoes.
Food Safety And Storage
Keep boiled egg whites in a covered container in the refrigerator and aim to eat them within about three to four days. Store them away from foods with strong smells, as whites can pick up odors. If the texture turns slimy, the color looks off, or the smell seems wrong, throw the batch away.
Finally, remember that any protein plan works best when it fits your health needs. If you live with kidney disease, high cholesterol, or other medical issues, talk with your healthcare team about how many whole eggs and boiled egg whites suit you before you make big changes to your plate.
