How Many Calories Are in a Teaspoon of Honey?

You’ve probably heard honey is a healthier sweetener than white sugar. But if you’re tracking calories, that spoonful of golden syrup might not be the free pass you hoped for. Honey is calorie-dense, and the difference between it and sugar is smaller than many people assume.

A single teaspoon of honey delivers about 21 calories—compared to 16 calories for the same volume of granulated sugar. Honey’s richer flavor means you may use slightly less, but the calorie savings are modest. This article looks at the numbers, the glycemic index, and what the differences mean for your diet.

Calorie Count for a Teaspoon of Honey

The exact number depends on the type of honey and how you measure it. A standard level teaspoon (7 grams) is generally considered to contain 21 calories. A tablespoon, which holds about 21 grams, bumps that to 63–64 calories as of 2025.

By weight, honey is one of the more calorie-dense sweeteners: 304 calories per 100 grams as of 2025. That’s about the same density as maple syrup and slightly higher than white sugar (which has around 387 per 100 grams, but because sugar is less dense by volume, a teaspoon of sugar weighs about 4 grams and gives you only 16 calories). The macronutrient profile of honey is essentially 100% carbohydrates, with negligible fat and only trace protein.

Those carbohydrates come from a mix of fructose and glucose. Unlike refined sugar, honey also contains small amounts of antioxidants and enzymes, though not enough to meaningfully affect the calorie count. If you’re measuring honey for a recipe or daily coffee, using a measuring spoon rather than the spoon you stir with makes a real difference.

Why Honey Seems Healthier Than Sugar

The perception that honey is significantly healthier stems from a few real differences—but none of them erase the calories. Here’s what sets honey apart from white sugar:

• Glycemic index difference: Honey has a moderate glycemic index, typically reported between 50 and 58, while table sugar scores 65 to 80. That means honey raises blood sugar somewhat more slowly, but the effect is still real—especially for anyone managing diabetes.
• Sweeter taste per gram: Honey is generally sweeter than sugar, so you can often use less to get the same level of sweetness. That can reduce the calorie load in a recipe, but it’s not automatic—you have to consciously adjust the amount.
• Trace beneficial compounds: Raw honey contains small amounts of antioxidants, enzymes, and flavonoids that refined sugar lacks. These compounds are not present in high enough concentrations to change the calorie math or offer a direct health benefit on their own.
• Natural perception: Because honey comes from flowers rather than a factory, many people view it as a “whole food” sweetener. While it’s less processed, it’s still a concentrated sugar source with similar calorie density to other liquid sweeteners.

None of these factors make honey a low-calorie food. They do make it a different choice from sugar, but for weight or blood sugar goals, portion awareness matters more than the sweetener type.

Honey in Your Daily Diet

When you add honey to tea, oatmeal, or yogurt, those 21 calories per teaspoon add up quickly. A tablespoon in your morning tea adds over 60 calories, and two tablespoons push past 120—about the same as a small piece of fruit.

Per WebMD’s glycemic index honey sugar page, honey raises blood sugar more slowly than table sugar, but it still contains sugar and calories like any other sweetener. The lower GI does not give honey a free pass; it just means the post-meal spike is a bit less steep.

The table below compares honey and white sugar for a typical serving:

Serving Size	Honey	White Sugar
1 teaspoon (7g)	21 calories, ~5.7g carbs	16 calories, ~4.2g carbs
1 tablespoon (21g)	63–64 calories, ~17g carbs	48 calories, ~12.5g carbs
100 grams	304 calories	387 calories
Glycemic index	50–58 (moderate)	65–80 (high)
Relative sweetness	1.0–1.5x sweeter than sugar	Baseline

Honey has more calories per teaspoon than sugar because it’s denser. But since it’s sweeter, you can trim the amount you use—potentially saving a few calories while still getting flavor.

How Portion Size Affects the Calorie Count

Small differences in measurement can shift the calorie total noticeably. Consider these common scenarios:

1. Level vs. heaped teaspoon: A level teaspoon is 7 grams (21 calories). A heaped teaspoon can easily hold 10–12 grams, doubling the calories to 30–36. If you’re scooping from the jar without leveling, you’re likely underestimating your intake.
2. Different honey varieties: Raw honey, Manuka honey, and creamed honey all have nearly identical calorie counts per gram. The floral source affects flavor and antibacterial properties, but not the energy content.
3. Measuring in fluid ounces: Some recipes call for honey by volume in tablespoons or fluid ounces. One fluid ounce of honey weighs about 42 grams and provides roughly 127 calories—easy to miss if you’re using liquid measuring cups designed for water.
4. Drizzling over food: A drizzle from a squeeze bottle adds around 8–9 calories for every 3 grams (about half a teaspoon). If you’re drizzling over pancakes or toast, a few “drizzles” can easily add up to 40–50 calories.
5. Honey in dressings and sauces: Mixed into vinaigrettes or marinades, honey’s calories blend in with other ingredients. A tablespoon of honey in a full-bottle dressing means each serving still includes honey’s sugar, even if you can’t taste it distinctly.

Using a kitchen scale for honey takes the guesswork out—especially if you’re on a calorie-controlled diet or tracking carbohydrates for diabetes.

Glycemic Index and Blood Sugar Impact

The glycemic index measures how quickly a food raises blood glucose. Honey’s GI is lower than sugar’s, but not low enough to be considered a “low-GI” food by most standards. Research published in the honey GI research study reports average GI values for honey around 50–58, depending on the floral source. For comparison, table sugar’s GI typically falls between 65 and 80.

That moderate GI means honey can still cause a notable blood sugar rise, especially in larger amounts. People with diabetes or prediabetes should account for honey’s carbohydrates the same way they would for any other sweetener—counting grams of carbs rather than relying solely on the GI score.

The following quick-reference table summarizes the key differences:

Metric	Honey	White Sugar
Calories per teaspoon	≈21	≈16
Glycemic index range	50–58	65–80
Carbohydrates per tsp	~5.7g	~4.2g

Both sweeteners affect blood sugar; the difference is a matter of degree. If you’re monitoring glucose, portion control matters more than the swap.

The Bottom Line

A teaspoon of honey adds about 21 calories to your day—slightly more than sugar by volume, but with a sweeter taste and a somewhat gentler effect on blood sugar. It’s not a low-calorie food, but it can fit into most eating patterns when you account for the carbs. Using a measuring spoon and adjusting for sweetness are the most practical steps.

For personalized carbohydrate counting or diabetes management, a registered dietitian can help you fit honey into your specific daily targets—the numbers here are averages, and your own portion habits may shift the total more than swapping sweeteners ever will.
