Is honey keto friendly? No: USDA lists honey at 82.4 g of carbohydrate per 100 g, so even 10 g carries 8.24 g of carbohydrate, a large share of a strict 20 grams daily limit.
This guide shows how much carbohydrate honey contains by weight, why nutrition authorities group it with added sugars, and which sweeteners people use instead. Honey is one of the sugar questions covered across the keto shopping list, which sorts staples by how they fit a low-carb plan.
Honey carbs by weight
USDA FoodData Central lists honey with 82.4 g of carbohydrate per 100 g, which means more than four-fifths of its weight is carbohydrate. Dietary fiber is 0.2 g per 100 g, protein is 0.3 g and fat is 0.0 g. With protein at only 0.3 g per 100 g, honey offers essentially nothing to balance its sugar. There is almost nothing in honey to subtract, so its total and net carbohydrate are nearly identical, at 82.2 g of net carbs per 100 g.
A spoonful weighs far less than 100 g, so the table below applies the USDA per-100 g values to smaller weights that are easier to picture.
| Honey weight | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 5 g | 4.12 g | 0.01 g | 4.11 g |
| 10 g | 8.24 g | 0.02 g | 8.22 g |
| 20 g | 16.48 g | 0.04 g | 16.44 g |
| 100 g | 82.4 g | 0.2 g | 82.2 g |
Per-weight values are calculated from the USDA FoodData Central record for honey, which supplies the nutrient values per 100 g.
Why honey counts as added sugar
Honey is often described as a natural alternative to table sugar, but Harvard’s Nutrition Source says that sweeteners which are not technically sugar, including honey, are in fact forms of added sugar. The page lists honey among the names for added sugar on food labels, alongside syrups.
The same page says your body does not need to get any carbohydrate from added sugar. For the general population, it says the Dietary Guidelines advise limiting added sugars to less than 10% of total calories, which works out to about 50 grams, or 12 teaspoons, per day on a 2,000-calorie diet. Harvard also notes that the average American adult, teenager and child consumes about 17 teaspoons of added sugar a day.
Against a ketogenic target, the arithmetic is tighter still. Harvard’s Nutrition Source describes the ketogenic diet as typically reducing total carbohydrate intake to less than 50 grams a day, and as low as 20 grams a day. A 20 g portion of honey carries 16.48 g of carbohydrate, which would use most of the strictest daily limit in a single serving.
How a spoonful of honey fits a daily limit
Because honey has almost no fiber, protein or fat, there is nothing in it to slow down or offset the sugar. The diet Harvard describes places a strong emphasis on fats at each meal and snack, and honey is the opposite of that pattern: it is nearly all carbohydrate, with 0.0 g of fat per 100 g.
Small amounts still add up. A 5 g drizzle in tea carries 4.11 g of net carbs, and several drizzles across a day can reach a double-digit total without anyone noticing. People who count carbs often weigh a sweetener once on a kitchen scale to learn what their usual spoonful weighs, then log that weight every time.
A practical way to judge a serving is to compare it with the daily range. Ten grams of honey carries 8.24 g of carbohydrate, which is a large share of a 20 gram day and a smaller but still noticeable share of a 50 gram day. Neither day leaves much room for vegetables, dairy and nuts if sweeteners take that much.
This is why honey is treated as sugar on a ketogenic plan rather than as fruit or dairy. The reason is not a judgment about honey in every context, but that its carbohydrate density is very high for a diet that caps the whole day at 20 to 50 grams, and Harvard lists it among the syrups and other names for added sugar.
Where honey hides in other foods
Honey shows up in more places than the jar. Food labels name honey in the ingredient list whenever it is used, and Harvard identifies breakfast cereals and yogurt as less obvious yet significant contributors of added sugar. Reading the ingredient list is the dependable way to catch it.
Warm milk with honey is a familiar habit, and the two stack: a cup of whole milk already carries 11.71 g of carbohydrate before any honey goes in, as covered in the guide to is milk keto friendly. Honey on toast or honey-sweetened loaves is the same issue in a different form, and the choices between regular and lower-carb loaves are set out in the guide on is bread keto friendly.
Sweetener swaps people use instead
Harvard’s Nutrition Source describes low-calorie sweeteners as sweeteners that contain few to no calories but have a higher intensity of sweetness per gram. They go by several names, including non-nutritive sweeteners, artificial sweeteners and sugar substitutes. Sugar alcohols form one group, with examples such as sorbitol, xylitol, lactitol, mannitol, erythritol and maltitol, and Harvard says they do not promote tooth decay or cause sharp rises in blood glucose.
Sugar alcohols are not free of caveats. The same page says that in some people, eating high quantities of certain sugar alcohols can cause loose stools or diarrhea. It also describes an observational study that linked higher blood erythritol levels to cardiovascular events, while noting that the researchers checked blood erythritol only once at the start. Harvard states that the health effects of low-calorie sweeteners are inconclusive, with mixed findings.
The simplest swap is to use less sweetener of any kind. Using less sweetener of any kind removes the carbohydrate outright: the 8.22 g of net carbs in a 10 g serving of honey is simply not eaten.
When to talk to a clinician
Cutting honey is a small step inside a larger change in eating. Harvard’s Nutrition Source recommends consulting a physician and a dietitian before starting a ketogenic diet. People with diabetes, kidney disease or a pregnancy, and anyone who takes medication, should talk to a clinician before changing how they eat, and this includes changes to sweeteners.

Frequently asked questions
How many carbs are in a tablespoon of honey?
That depends on the weight of the spoonful, which varies with how it is filled. Based on USDA values, every 10 g of honey carries 8.24 g of carbohydrate, so weighing the spoonful gives the exact figure.
Does honey contain fiber?
Barely. USDA lists 0.2 g of dietary fiber per 100 g of honey, against 82.4 g of carbohydrate.
Is honey an added sugar?
Yes. Harvard’s Nutrition Source lists honey among the names for added sugar on food labels and says sweeteners that are not technically sugar are in fact forms of added sugar.
Do sugar alcohols raise blood sugar like honey does?
According to Harvard’s Nutrition Source, sugar alcohols do not cause sharp rises in blood glucose, although high quantities of some can cause loose stools or diarrhea in some people.
