Soda can be a sneaky source of calories if you're not careful, leading to weight gain if you drink a lot of soda throughout the day, but what about coca-cola? Is it high in syns?

A 500ml bottle of coca cola has 10 syns making this drink very high in syns, for a 330ml you are looking at using 6.5 syns.
In our syn guide below we will discuss why coca cola is so high in syns, some syn values and low syn alternatives of other sodas to keep your syns on track.
At 10 syns for a 500ml bottle and 6.5 syns for a 330ml can, coca-cola is very high in syns using over half of your daily syn allowance on the slimming world plan. Original coca-cola gets its high syn value from the sugar content having 35g of sugar in one 330ml can which is your whole recommended intake of sugar for the day.
Coca-cola has a huge range of drinks on offer, with diet and sugar-free options to help keep syns low, we've listed most of their range along with their syn values down below.

If you find coca cola to be too high in syns there are lots of other low-syn soda alternatives, we've listed some options down below so you can compare syns.

To conclude, coca-cola is a very high drink if you choose the full sugar options, having up to 35g of sugar in just one can of the drink and around 6.5 syns which is around half of your daily syn allowance. To save syns we suggest opting for no sugar diet drinks when you crave soda which is most of the time syn free.
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.
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.
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.
