How to calculate approximate syns for Slimming World snacks

If you are looking to eat something which has no free food component then use a simple rule of every 20 calories is one syn.

Additionally, 10 calories is 0.5 syn. So a chocolate bar which is 99 calories is 5 syns as this is so close to 100 calories the difference is negligible. If something is 110 calories then count it as 5.5 syns.

Graphic containing the words How many syns?

Using this trick makes shopping for snacks really easy as a quick glance gives you an idea of the syns. What are your favourite Slimming World low syn snacks?

If you enjoy baking then you need to add up the syns in each individual ingredient and then divide by the number of portions you make.

Home cooking is so much nicer, isn’t it? How about trying this three-ingredient shortbread? Easy to make and easy to work out the syns for, not only that but delicious too!
