How many carbs are in lemonade?
One serving of lemonade made from powder mix (18g of powder) has about 18g of carbohydrate, with 17g coming from sugar. It is almost pure sugar water with a tiny amount of fiber from the powder.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 serving powder mix (18g, makes ~1 glass) | 17.6g | 0.1g | 17.5g |
| 1 cup (218g) | 212.7g | 0.9g | 211.8g |
| 100 grams | 97.6g | 0.4g | 97.2g |
Net carbs
One serving of powdered lemonade mix has about 17.5g of net carbs, which is essentially identical to total carbs (18g) because the fiber content is negligible at under 0.1g per prepared serving. See the net carbs guide for context on liquid carb sources.
Glycemic index of lemonade
The glycemic index of lemonade is about 70. Sugary lemonade behaves like other sugar-sweetened beverages. The liquid format means there is no food matrix to slow digestion, so glucose enters the bloodstream quickly. Homemade lemonade with real lemon juice and table sugar has a similar glycemic impact.
For diabetes
Lemonade is essentially a sugar drink. One prepared serving delivers about 18g of fast-acting carbs with nothing to slow the rise. No fiber, no protein, no fat. For people with diabetes, sweetened lemonade raises blood glucose quickly and requires the same insulin planning as soda or juice. Sugar-free lemonade mix made with artificial sweeteners has near-zero carbs and is a common substitute. See the diabetes carb-counting guide.
Keto and low carb
One serving of regular lemonade from powder mix has about 17.5g of net carbs, all from sugar. It does not fit keto at any typical serving size. Sugar-free lemonade mix with stevia or sucralose has essentially zero carbs and works on keto.
Good to know
Powdered lemonade mix is highly concentrated, so the carbs per 100g look extreme (about 98g of carbs) because the 100g is dry powder, not prepared drink. A single 18g serving packet mixed into a glass of water is the realistic portion. Freshly squeezed lemon juice alone has only about 2g of carbs per ounce because it contains very little sugar, but prepared lemonade requires added sugar to be drinkable.

How many carbs are in lemonade?
One serving of lemonade from powder mix has about 18g of carbs. A 12 oz glass of typical bottled or restaurant lemonade ranges from 30g to 45g of carbs depending on how sweet it is.
Is lemonade high in sugar?
Yes. A single serving of powdered lemonade mix has about 17g of sugar. Most of the carbs in lemonade come directly from added sugar.
Does lemonade spike blood sugar?
Yes. Lemonade is a liquid sugar source with no fiber or protein to slow absorption. Blood glucose rises quickly after drinking it, similar to soda or fruit juice.
Is lemonade keto?
Regular lemonade is not keto. One serving has about 17 to 18g of net carbs from sugar. Sugar-free lemonade made with zero-calorie sweeteners has near-zero carbs and fits keto.
How many carbs in fresh-squeezed lemonade?
It depends entirely on how much sugar is added. The lemon juice itself contributes about 2 to 3g of carbs per ounce. Most fresh lemonade recipes add enough sugar to bring a 12 oz serving to 30g of carbs or more.
