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.
