French fries can be enjoyed on the slimming world diet in moderation, flavoured versions of the crisps have the same amount of syns as an original 22g bag, and with the allowance of slimming world being around 15 syns per day, you can enjoy one large bag per day without breaking your diet. 

However, there are some other lower syn crisps you can try if you would rather give the french fries a miss which we will get on to next.

We would always recommend opting for the gluten-free versions, light versions or multi-pack versions of your crips as they will often be half-syn versions due to their lighter weight and lower calories, you can have a pinch of salt sprinkled on your light version if you want a saltier taste, but this gives you more control.
