Honey is a natural sweetener with a complex carbohydrate profile, but its effect on blood sugar varies widely by variety and serving size. This calculator estimates the glycemic load (GL) of any honey serving — a more practical measure than glycemic index (GI) alone because it accounts for both the carbohydrate content and the portion you actually eat.
Whether you're managing diabetes, following a low-glycemic diet, or simply curious about how different honeys compare, this tool gives you a quick, science-based answer. Just select the honey type, enter your serving size, and get the glycemic load along with a clear interpretation. Use it to make informed choices about sweeteners in your daily meals.

How to Use This Tool
Select the honey variety from the dropdown — each type has a known glycemic index (GI) value based on published research. Then enter your serving size and choose the unit (grams, tablespoons, teaspoons, or ounces). Click Calculate GL to see the glycemic load, carbohydrate content, and a plain-language interpretation. Use the preset buttons for common serving sizes like 1 teaspoon or 1 tablespoon.
Tip: For the most accurate results, weigh your honey on a kitchen scale. Volume measurements (tablespoons, teaspoons) are approximate because honey density varies slightly by variety and temperature.
Formula Explained
Glycemic load is calculated using the formula:
GL = (Carbohydrates per serving × GI) / 100
Where Carbohydrates per serving = (grams of honey × 0.82) — honey is roughly 82% carbohydrate by weight, primarily fructose and glucose. The GI is a value from 0 to 100 that measures how quickly a food raises blood sugar relative to pure glucose. By multiplying by the actual carbohydrate content, GL gives a more realistic picture of a food's blood sugar impact for a typical serving.
For example, a 21 g serving of clover honey (GI 58) contains about 17.2 g of carbs. The GL is (17.2 × 58) / 100 = 10.0 — a low GL. The same serving of acacia honey (GI 32) yields a GL of only 5.5.
Worked Examples
Example 1: 1 tablespoon (21 g) of Manuka honey (GI 54). Carbs = 21 × 0.82 = 17.2 g. GL = (17.2 × 54) / 100 = 9.3 → Low GL.
Example 2: 2 tablespoons (42 g) of wildflower honey (GI 62). Carbs = 42 × 0.82 = 34.4 g. GL = (34.4 × 62) / 100 = 21.3 → High GL.
Example 3: 1 teaspoon (5 g) of acacia honey (GI 32). Carbs = 5 × 0.82 = 4.1 g. GL = (4.1 × 32) / 100 = 1.3 → Very low GL.
Factors Affecting Accuracy
The GI values used in this calculator are averages from published studies. Actual GI can vary due to floral source, processing, and individual differences in digestion. Honey is a natural product — its sugar composition (fructose-to-glucose ratio) changes with season and region. For instance, acacia honey is naturally high in fructose, giving it a lower GI, while clover honey has more glucose and a higher GI. Always consult your healthcare provider for personalized dietary advice, especially if you have diabetes or insulin resistance.

Frequently Asked Questions
Is honey better than sugar for blood sugar control? Honey generally has a lower GI than table sugar (sucrose, GI ~65), but it still raises blood sugar. Because honey is sweeter, you may use less of it, which can lower the glycemic load of your meal. However, both should be used in moderation.
Can diabetics eat honey? In small amounts, honey can be part of a diabetic diet, but it's important to account for the carbohydrates. A serving of 1 teaspoon (5 g) of acacia honey has a GL of about 1.3, which is very low. Always monitor your blood sugar response and consult your doctor.
Why does the calculator use 82% carbs? Honey's carbohydrate content is consistently reported as 80–83% by weight in USDA food composition databases. We use 82% as a reliable average. The remaining weight is water (17–18%) and trace amounts of vitamins, minerals, and enzymes.
What is the difference between GI and GL? Glycemic index (GI) measures how fast a food raises blood sugar per gram of carbohydrate, but it doesn't account for serving size. Glycemic load (GL) multiplies GI by the actual carbohydrate content in a serving, giving a more realistic measure of blood sugar impact. For example, watermelon has a high GI (72) but a low GL (about 5 per 100 g) because it's mostly water.
