How Many Syns in Snack-a-Jacks?
By Jenny Updated
Snack-a-Jacks costs 5 syns per 1 bag sweet caramel (25g) on Slimming World. It is not free, but it is manageable within your daily allowance with a little planning. Lower-syn than standard crisps but not free. The sweet caramel flavour is the highest. A decent crunch fix for around 4 to 5 syns. Most packaged snacks carry syn values on Slimming World, but that does not make snacking off-limits — it makes planned snacking far more effective than unplanned eating. Deciding your snack at the start of the day and counting it into your allowance in advance works much better than restricting snacks entirely and then eating something unplanned when hunger hits. Lower-syn options like Walkers Baked, Quavers, and rice cakes give you something satisfying for three to four syns.
