Are Frosted Shreddies High In Syns On Slimming World? - Our Unofficial Syn Guide

Finding a slimming world-friendly cereal isn't easy, some brands are packed full of sugar, having syns up to 6 syns a portion which is nearly half your syn allowance, but what about frosted Shreddies, are they high in syns?

Frosted Shreddies have 7.5 syns for a 40g serving, making them high in syns, and taking you over half of your daily syn allowance on the plan.

We've discussed below in more detail why this cereal is so high in syns, syn values of Shreddies in general and some low syn alternative cereals for a syn-friendly breakfast!

Why Are Frosted Shreddies So High In Syns?

At 7.5 syns for a 40g portion, Frosted Shreddies are very high in syns, using over half of your 15 syn daily allowance on the plan, meaning you could have up to two portions in one day.

This cereal gets its high syn value from the sugar content, with a 40g portion having 9g of sugar inside, we, therefore, suggest only having this cereal in moderation, or choosing plain cereal like Weetabix which can also count as your healthy extra B!

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.
