Are Chewits Slimming World Friendly? - Our Syn Guide

If you're looking for a sweet treat to have during the day on hand, you might be tempted to grab some chewits, but how many syns do these little sweets have on the slimming world plan?

Are Chewits Slimming World Friendly?

Chewits have on average 6 syns for a packet, making them fairly high in syns and consuming nearly half of your daily syn allowance on the plan. 

We've discussed in more detail below why Chewits are so high in syns, some syn values of them and some low syn alternative sweets to satisfy your sweet tooth.

Why Are Chewits So High In Syns?

At 6 syns for a pack, Chewits are high in syns, a half-pack serving would cost you 3 syns, allowing you to have up to two packs before using most of your 15 syn daily allowance.

Chewits get their high syn value from the sugar content having around 15g of sugar per stick pack, we, therefore, suggest having them in moderation.

We recommend having sweets like Chewits in moderation due to their high sugar content or checking out our low syn alternatives which start as low as 1.5 syns a sweet. Sugar-free sweets can also be a good alternative if you are trying to cut back on sugar.

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.
