Olives in brine have around 2 syns for 30g on the slimming world plan, making them low in syns, allowing you to have up to around 350g before using all your daily syns!

We've created a syn guide below, taking you through why olives in brine are low in syns, some syn values of different olives and some low syn alternatives for tapas or antipasti snacks.

Why Are Olives In Brine So Low In Syns?

At 2 syns for 30g, olives in brine are quite low in syns, allowing you to have up to around 350g before using all your 15 syn daily allowance.

These olives are low in syns since they are stored in brine instead of olive oil, oil adds a lot of calories and fat to the olives, you can expect olives stored in oil and other ingredients to have around 3-4 syns for 30g.

Also, be cautious of olives which are stuffed with cheese or store in packets with other antipasti veggies since this can add extra hidden 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.
