How to choose the lowest calorie drinks at Costa
Maintaining healthy eating and drinking on a diet can be challenging, especially when you’re out and about. However, you can make smart choices even when visiting popular cafes and coffee shops.
If you’re a fan of Costa Coffee, you’ll be pleased to know that there are plenty of drink options to enjoy while staying true to your health goals.
In this post, we’ll discuss some of the delicious and guilt-free beverages you can enjoy at Costa whilst staying on track with your diet and without missing out on your favourite drinks.

Black Coffee
A cup of black coffee is a great choice for those watching their calorie intake. A regular-sized black coffee at Costa contains minimal calories, making it an ideal choice for a low-calorie beverage. Feel free to add a natural sweetener or a splash of milk if you prefer a milder flavour.

Herbal or Green Tea
If you prefer tea over coffee, Costa has a range of herbal and green tea options that are perfect for those on a diet.
Choose from a variety of flavours like Citrus Zing, Mint and Spiced Apple, or green tea, all of which are virtually calorie-free.
These teas will provide a refreshing boost and offer numerous health benefits, including aiding digestion and promoting relaxation.
Skimmed Milk Latte
A skimmed latte can be a great compromise for those who crave a creamier option. Made with skimmed milk, the calorie content is reduced considerably compared to a latte made with full-fat milk.
The frothy texture and rich coffee flavour make it a satisfying choice without sacrificing too many calories.
If Latte isn’t your coffee, you can also ask for a skimmed Cappuccino, Mocha, Cortado or Flat White to lower the calorie count.

Iced Coffee and Tea
When the weather calls for a cool beverage, Costa offers an array of iced drinks to refresh you without compromising your diet.
Opt for an iced coffee made with skimmed milk and sugar-free syrup: or a refreshing iced tea. These beverages provide a delightful cooling effect, making them a perfect treat on a warm day.
Hot Chocolate
If you have a sweet tooth but want to watch your calorie intake, a skimmed Hot Chocolate might be the perfect choice.
Request it to be made with skimmed milk and a reduced amount of chocolate powder; this guilt-free treat will satisfy your cravings without sabotaging your diet.
Just be mindful of portion sizes and enjoy it as an occasional indulgence rather than a daily habit.

Frappe or Fruit Cooler
Costa has you covered if you’re looking for a low or non-caffeinated drink or want to mix things up. Stay hydrated and satisfied with their selection of frappes or fruit coolers.
Fruit coolers with real fruit juice and sparkling water offer a fruity, tangy indulgence while keeping calorie counts low. Although made with milk, Frappes can be made using skimmed, semi-skimmed, coconut or oat milk. These are all delicious and lower in calories.
Be sure to request these as otherwise; Costa has the standard of using whole milk quite often!
Coconut or Oat Milk
For those following a dairy-free or vegan diet, Costa has options to cater to your needs. Try a coconut or oat milk variation of your favourite drink for a creamy and indulgent beverage without dairy.
These alternative types of milk add a unique flavour to your drink while lowering the calorie count.

You can enjoy any of your favourite drinks in Costa; making a few slight changes makes them a healthier choice without compromising their taste. Why not
- Try a dairy alternative drink – Request a plant-based drink and substitute the milk for coconut, oat or soya.
- Go sugar-free – Choose from different sugar-free syrups without added calories.
- Downsize your order – Order your favourite drink but in a smaller size.
- Have less syrup – Ask for less or no pumps at all.
- Try the light whip – This vegan alternative to cream is light, tastes great and only has 76 calories per serving.
Remember that any drink you purchase has an approximate calorie value and should be used as a guide only as they are made to order, so there may be slight differences.
Sticking to a diet doesn’t entirely mean giving up your favourite coffee shop treats. At Costa, you can still enjoy a delicious and satisfying beverage while staying on track with your health goals.
There are plenty of options, whether you prefer a classic black coffee, a latte, or a refreshing iced tea. Remember to be mindful of your choices; if desired, you can customise your drink with skimmed milk, sugar-free syrups, or natural sweeteners.
If you have specific dietary requirements or concerns, checking with the barista for detailed nutritional information or ingredient lists is always a good idea.
