You've probably heard for years that eggs are the "perfect food." They're cheap, they're everywhere, and they've survived a few decades of being the villain in the cholesterol wars. But if you’re standing in your kitchen at 7:00 AM wondering how many carbohydrates in eggs before you start your day, the answer isn't a flat zero. It's close. But it's not zero.
Most people track their macros like it's a second job. If you're on keto or managing diabetes, every fraction of a gram counts. Here is the reality: a large, Grade A egg contains roughly 0.6 grams of carbohydrates.
That’s it.
Basically, you’d have to eat about 20 eggs to even hit 12 grams of carbs, which is less than what you’d find in a single slice of mediocre white bread. But where do these carbs even come from? Eggs aren't plants. They don't have starch. The trace amount of carbohydrate found in an egg is mostly glucose, stored in the white and the yolk to provide a tiny energy reserve for a developing embryo. It’s biology, not a nutritional "gotcha."
Why the "Zero Carb" Label is Kinda Lying to You
Food labeling laws in the United States, governed by the FDA, allow companies to round down. If a serving size contains less than 0.5 grams of a nutrient, the manufacturer can legally list it as "0." Since many smaller eggs or specific preparations hover right around that 0.4g to 0.5g mark, you’ll often see "0g Carbs" on the carton.
It's a rounding error.
If you are just casually eating a couple of scrambled eggs, this doesn't matter. But if you are a "beast mode" athlete eating a twelve-egg omelet, you’ve actually just consumed about 7 grams of carbohydrates. Is that going to kick you out of ketosis? Probably not. But for the data nerds among us, accuracy matters.
The USDA FoodData Central database is the gold standard here. According to their analysis of a large, raw egg (about 50 grams), the exact breakdown shows 0.36 grams of total carbohydrates. However, factors like the hen’s diet, the age of the egg, and even the specific breed can cause slight fluctuations. You’re never going to find an egg with 5 grams of carbs unless it’s been injected with maple syrup—which, honestly, sounds like a terrible culinary experiment.
The Yolk vs. The White: Dividing the Macros
Most of the "good stuff"—the fat-soluble vitamins like A, D, E, and K—lives in the yolk. The whites are basically just water and protein. But when we look at how many carbohydrates in eggs based on their components, the distribution is surprisingly even.
The egg white (the albumen) contains approximately 0.2 grams of carbs.
The yolk contains approximately 0.3 grams of carbs.
Interestingly, the yolk is more nutrient-dense in every single category. It’s got the choline your brain needs. It’s got the lutein for your eyes. If you’re tossing the yolk because you’re afraid of the fat, you’re missing the point of the egg. The yolk is the battery. The white is just the casing.
Dr. Robert Lustig, a well-known neuroendocrinologist who has spent years railing against the dangers of processed sugar, often points out that real, whole foods like eggs are self-contained nutritional units. The tiny bit of glucose in an egg isn't "added sugar." It's an intrinsic part of the cell structure. It won't spike your insulin. Your pancreas barely even notices an egg is happening.
How Cooking Changes the Carb Count
Heat doesn't magically create carbohydrates. If you boil an egg, it still has 0.6 grams of carbs. If you poach it, same story.
The trouble starts when you introduce the "plus-ones."
- Scrambled with Milk: Adding just a splash of whole milk adds about 1 gram of lactose (milk sugar).
- The "Diner" Omelet: Many restaurant chains actually mix pancake batter into their omelet mix to make them fluffier. I'm serious. This can turn a "zero carb" breakfast into a 20-gram carb bomb before you even touch the toast.
- Fried in Butter: Pure fats like butter or oil have zero carbs. So, a fried egg remains a low-carb champion.
- Deviled Eggs: This is where things get dicey. Between the mayo (usually fine), the mustard (usually fine), and the "secret" teaspoon of sugar many grandmas add to the filling, you could be looking at 2-3 grams per egg half.
You've gotta be your own detective. If you're at a restaurant, ask if they use "shell eggs" or a pourable mix. The pourable mixes often have stabilizers and citric acid that can slightly nudge the carb count upward, though usually not enough to ruin a diet.
Beyond the Macros: The Micronutrient Powerhouse
Focusing solely on how many carbohydrates in eggs is like looking at a Ferrari and only asking about the cup holders. Yeah, the cup holders are small, but look at the engine!
Eggs are one of the few natural food sources of Vitamin D. Most of us are deficient, especially if we work in an office and haven't seen the sun since 2022. They also contain high levels of Riboflavin (B2) and Selenium.

Then there is the protein. Egg protein is the "Gold Standard" by which other proteins are measured. It has a biological value of 100, meaning your body can actually use almost all of it for muscle repair and enzyme production. Compare that to plant proteins, which usually sit in the 60s or 70s. You aren't just eating 6 grams of protein; you're eating 6 grams of highly efficient protein.
The Myth of the "Egg-Induced" Sugar Spike
Some people worry that high-protein meals can trigger gluconeogenesis—a process where the liver turns excess protein into glucose. This leads to the fear that eating too many eggs will raise blood sugar just like eating a potato would.
Research published in the British Journal of Nutrition has largely debunked the idea that normal protein consumption causes a meaningful rise in blood glucose in healthy individuals. The body is smarter than that. It only turns protein into sugar when it absolutely needs to. For the vast majority of people, eggs remain one of the most stable foods you can put in your body for blood sugar management.
What About "Egg Substitutes" and Plant-Based Options?
If you're looking at those yellow cartons of plant-based "eggs" made from mung beans or soy, the carb count changes.
JUST Egg, for example, has about 1 gram of carbohydrate per serving. It's still very low, but it's technically double the carbs of a chicken egg. These products also use gums and thickeners like transglutaminase or gellan gum to mimic the texture of a real egg.
They aren't "bad," but they aren't the same.
If you're eating "liquid egg whites" from a carton, check the label. Some brands add "natural flavors" or colorants that might introduce a negligible amount of carbohydrates. Usually, though, liquid whites are just as carb-depleted as the ones you crack yourself.
Actionable Takeaways for Your Next Meal
Knowing how many carbohydrates in eggs is only useful if you apply it. Here is how to handle egg-buying and cooking if you are strictly monitoring your intake:
- Trust the Shell: Buy whole eggs in the shell. This eliminates any chance of additives or "fluffing agents" found in pre-mixed versions.
- Size Matters: A "Jumbo" egg can have nearly 0.9 grams of carbs, while a "Small" egg might have 0.3 grams. If you're eating six a day, that gap adds up.
- Watch the Omelet Add-ins: Onions, bell peppers, and especially tomatoes have their own sugar content. A vegetable-heavy omelet can easily hit 5-8 grams of carbs. It’s "healthy" fiber, sure, but if you’re on a strict 20g-a-day limit, keep the veggies in check.
- The Hard-Boiled Hack: Hard-boiled eggs are the ultimate travel snack. They stay stable and the carb count remains locked at roughly 0.6g. Just don't be that person who eats them on a crowded airplane.
- Check Your Mayo: If you're making egg salad, use a mayo made with avocado oil or olive oil that doesn't use sugar as a filler. Many "light" mayos replace fat with corn starch or sugar, which doubles the carbs in your egg salad.
Eggs are, and likely always will be, the king of low-carb living. They are cheap, versatile, and functionally zero-carb for anyone who isn't a professional mathematician. Stop worrying about the 0.6 grams and start focusing on the incredible density of vitamins you're getting for about 70 calories.
Next time you're at the grocery store, grab the pasture-raised carton if your budget allows—the yolks are oranger, the flavor is deeper, and while the carbs are the same, the nutrient profile is often superior due to the hen's varied diet of bugs and grass.
Your Next Step:
Go check your fridge. If you have "liquid egg" cartons, read the ingredient list for "maize starch" or "sugar." If you find them, consider switching back to whole shell eggs for your next breakfast to keep your carb intake as close to zero as possible. For your next meal, try poaching your eggs instead of frying them; it preserves the delicate fats in the yolk without adding the oxidized oils often used in high-heat frying.
