Lemonade is a classic, refreshing drink perfect for hot weather or as a tangy mixer. But its sweet, citrusy flavour often comes with a hidden sugar load. So how many calories are in a lemonade? That depends on whether it’s homemade, shop-bought, sparkling, or diet. The calorie content can vary massively between types and serving sizes.

Calorie Content by Type and Serving Size

A standard glass of lemonade (250ml) made from sugar, lemon juice, and water typically contains 90 to 120 calories, depending on how sweet it is.

Here’s a breakdown by type:

  • Homemade lemonade (250ml): 90–120 calories
  • Bottled still lemonade (250ml): 100–150 calories
  • Carbonated lemonade (250ml can): 105–130 calories
  • Diet lemonade (250ml): 1–5 calories
  • Lemonade cordial (30ml concentrate + water): 60–80 calories depending on dilution

Larger servings like takeaway lemonades or café-style drinks  can easily exceed 300 calories, especially if sweetened syrups or flavour shots are added.

Nutritional Breakdown of Regular Lemonade

Per 250ml glass of classic lemonade:
Calories: 100
Fat: 0g
Carbohydrates: 26g
Sugars: 24g
Protein: 0g
Salt: 0g

Lemonade is virtually fat-free and contains no protein or fibre. The bulk of the calories come from simple sugars, usually white sugar or glucose-fructose syrup in bottled varieties.

What’s in Lemonade?

Traditional homemade lemonade is made with fresh lemon juice, sugar, and water. The lemon juice gives it its tartness and vitamin C content, but the sugar is what drives the calorie count.

Commercial lemonade may include:

  • Carbonated water
  • Sugar or glucose-fructose syrup
  • Citric acid
  • Lemon flavouring (natural or artificial)
  • Preservatives (like potassium sorbate)
  • Colouring

Diet lemonades swap sugar for artificial or non-nutritive sweeteners such as aspartame, sucralose, or stevia.

Benefits of Lemonade

The main benefit of lemonade is its hydrating nature and its vitamin C content when made with real lemon juice. Vitamin C supports immune health and acts as an antioxidant. Homemade lemonade made with minimal sugar can be a refreshing, healthier drink  especially when compared to fizzy colas or energy drinks.

Downsides of Lemonade

Most lemonades are high in sugar and low in nutrients. A single glass can contain 6–7 teaspoons of sugar, close to the NHS-recommended daily limit for added sugars. Regularly drinking sugary lemonade can contribute to:

  • Weight gain
  • Tooth decay
  • Increased risk of type 2 diabetes
  • Blood sugar spikes and crashes

Carbonated lemonades are also acidic, which may erode tooth enamel over time.

How Lemonade Affects Your Diet

Lemonade can quickly add empty calories to your day, especially if you’re not tracking liquid intake. These calories don’t provide satiety or essential nutrients, and they can sneak past your radar, making weight management harder.

If you’re actively monitoring your calorie intake, swapping regular lemonade for diet or unsweetened versions can be a simple way to cut back.

Glycaemic Index Rating

Regular lemonade has a high glycaemic index, thanks to its sugar content and lack of fibre or fat to slow absorption. This means it causes a rapid spike in blood glucose levels something to be mindful of if you’re diabetic, insulin-resistant, or on a low-GI diet.

Diet lemonades, on the other hand, have a GI close to zero because they use non-glycaemic sweeteners.

Healthier Alternatives

If you’re looking to enjoy lemonade without the sugar overload, try swapping for sparkling water with lemon slices and a few drops of stevia, homemade lemonade with half the sugar or honey, lemon-infused iced green tea or lemon water with mint and cucumber for a detox-style drink

These give you the same refreshing citrus hit without all the sugar and calories.

Summary

So, how many calories are in a lemonade? On average, 100–130 calories per 250ml glass, with the bulk of it from sugar. Diet versions come in at nearly zero but may include artificial sweeteners. Lemonade can be enjoyed occasionally, especially when homemade and lightly sweetened, but it’s best not to treat it as a guilt-free drink. If you're watching your calorie or sugar intake, switch to lower-sugar versions or create your own light alternative at home.
