Are KitKat's High In Syns On The Slimming World Diet?

Kit kat's are a nations favourite to snack on, but since these chocolate bars are not syn free you need to ensure that you track their syn values according to their calories to not gain weight.

These Kit Kat's chocolate bars have 5 syns per bar making them a high syn treat, but fine to eat on the slimming world plan within moderation when you crave chocolate.

To find out more about how many Kit Kat's you can eat on the slimming world plan, some syn values of the Nestle chocolate bar range and some low syn chocolate wafer alternatives we've put all the information you need to know in a small guide below.

How Many Kit Kat's Can I Eat On Slimming World?

Kit Kat's are fine to indulge in now and again on the slimming world plan but at 5 syns a bar, you could only have up to three bars a day before reaching your daily 15 syn a day allowance.

Kit Kat's in comparison to other chocolate bars are quite low in syns however due to them having a light wafer in, this makes them bigger in volume and more of a biscuit, reducing their calories slightly.

Still, at 10g of sugar for just one bar you need to make sure you are eating these chocolates in moderation, we would not suggest eating more than one bar per day. We would also suggest checking whether they are standard Kit Kat's or Kit Kat chunky as the latter is higher in syns due to their bigger size with some having up to 9 syns.
