Yes — eggs are keto. A large egg has about 0.4g of carbs, which rounds to 0g net carbs, plus 5g of fat and 6g of protein. There’s no flour, no fruit, nothing on keto that’s lower-carb and more useful.
Eggs are the food I cook with most, and almost none of it is breakfast. Below: the actual carb numbers (whole egg, white, and yolk), the whole-vs-white question, and the one that worries people most: what eating this many eggs does to your cholesterol.
How many carbs are in eggs?
A large egg’s carbs are so low they’re a rounding error. Here’s the breakdown per 1 large egg:
| Per 1 large egg | Net carbs | Fat | Protein | Calories |
|---|---|---|---|---|
| Whole egg | ~0.4g | 5g | 6g | 72 |
| Egg white only | ~0.2g | 0g | 4g | 17 |
| Egg yolk only | ~0.6g | 4.5g | 3g | 55 |
Even a full dozen has only about 5g of carbs total. For practical purposes, count eggs as zero net carbs in your day. You’ll hit your carb limit on the things you cook with the eggs long before the eggs themselves matter.
Are eggs zero carb?
Close enough. That ~0.4g per egg is a trace of naturally occurring sugar, with no fiber and no added sugar. Most keto trackers list a large egg at 0g net carbs, and that’s a fair way to count it. The thing to watch isn’t the egg, it’s what goes around it: ketchup, sweet breakfast sausage, a flour tortilla. The egg is never the problem.
Whole eggs vs. egg whites on keto
This is where I see people get it backwards. Egg-white omelets are a habit left over from low-fat dieting, and on keto they pull you the wrong way. The white is almost pure protein with essentially no fat. The yolk is where about 4.5g of the 5g of fat lives, and where the vitamins are: D, B12, choline, and the antioxidants lutein and zeaxanthin.
Keto runs on fat, not protein. Tossing the yolks means tossing the fat and the nutrition and keeping only the part that nudges you toward too much protein. Eat the whole egg. It’s not a cheat, it’s the point.
What about cholesterol on keto?
This is the question I get most, so let me be straight about it. For decades eggs were treated as a cholesterol threat because a yolk has about 186mg of dietary cholesterol. The science has shifted: for most people, the cholesterol you eat has a smaller effect on the cholesterol in your blood than the saturated fat and refined carbs you eat, and the U.S. dietary guidelines dropped their specific cholesterol limit back in 2015.
That said, two honest caveats. Some people are “hyper-responders” whose LDL rises more than average from dietary cholesterol. And keto itself (the whole high-fat way of eating, not eggs specifically) raises LDL in a subset of people. So eggs aren’t a free pass to ignore your numbers.
My take, and I’ll say it plainly since I’m a pharmacist and not your doctor: eggs are a nutritious, keto-perfect food for most people, and the old “eggs wreck your cholesterol” line is outdated. But if you’re eating keto, get a lipid panel, know your own numbers, and work with your doctor, especially if your LDL climbs. Personalize it; don’t guess.
How many eggs a day on keto?
There’s no keto rule capping eggs, and no strong evidence that a few eggs a day is a problem for healthy people. I routinely eat two to four, between what I cook and what I bake. If you have a diagnosed lipid condition, that’s a conversation for your doctor, but for most people, eggs a day is a feature of this diet, not a risk.
The best way to use eggs on keto
Eggs are the structure keto baking lost when the gluten went away. They bind, they lift, they hold a chaffle together. I lean on them for keto bread, chaffles, custards, and a fridge full of hard-boiled eggs for fast protein.
I’ve put my whole egg playbook (the chaffle, why room temperature matters, the binding ratios) plus every egg recipe I make in one place:
