Costa Hot Chocolate: How Many Syns and How to Enjoy It on Slimming World

As the seasons get colder you might start craving hot chocolate to warm you up, but you do need to be careful about the syns in hot chocolates, especially when ordering from cafes like Costa.

Is Costa Hot Chocolate High In Syns?

Costa hot chocolate in particular has varying syns according to the kind of milk you choose, on average for small hot chocolate made with semi-skimmed milk you will be spending around 8.5 syns per drink.

We've discussed in further detail below why Costa hot chocolate is so high in syns, syn values of all their hot chocolates and some low syn alternatives from other coffee shops and brands.

Why Is Costa Hot Chocolate So High In Syns?

At 8.5 syns per small hot chocolate with semi-skimmed milk, these hot drinks are fairly high in syns, consuming half of your daily syn allowance on the plan, we, therefore, suggest having them as an occasional treat when your syns allow.

Costa hot chocolate gets its high syn value from the sugar and fat due to the chocolate in the drink, for example, one small hot chocolate from Costa has nearly 20g of sugar and 5g of fat!

To save syns we suggest choosing lower fat kinds of milk like skimmed milk and choosing the mini size which is even lower in syns.

Frequently Asked Questions

How are syn values calculated?

Syn values are calculated using a formula based on calories, saturated fat and sugar content per serving. They’re not the same as calories — a product can be low in calories but higher in syns if it’s high in sugar or fat. Always check the official Slimming World app for the most accurate and up-to-date syn values.

Do syn values change?

Yes. When manufacturers reformulate their products, the syn value can go up or down. This is why we recommend double-checking with the Slimming World app or your consultant, especially if a product’s packaging has changed recently.

How many syns should I have per day?

Most Slimming World members work with 5 to 15 syns per day. Your consultant will advise on the right amount for you. The key is to use your syns on the things you enjoy most — whether that’s a chocolate bar, a glass of wine, or a packet of crisps.
