Tips For Making A Low Syn Coffee

If you are the kind of person who has a few sugars in their coffee and doesn't give much thought to the amount of milk they are using, you might be surprised as to how many syns these ingredients can add.

We've listed some of our best tips for keeping your coffee with milk low in syns below.

  • Switch to sweetener - If you are used to having a couple of sugars in your coffee you could be adding up to 2 syns without you knowing, instead switch to sweetener which is much lower in syns.
  • Go for a low-fat milk/non-dairy - Lower fat kinds of milk like skimmed and almond milk are much lower in syns than whole milk if you can't drink your coffee black.
  • Measure your milk - By freely pouring your milk into your coffee you can add much more syns than you think, instead measure it out to stay on track.
  • Avoid flavourings - When making your coffee or having one from the coffee shop, avoid opting for syrups in your drink, these can add a lot of syns and sugar if you are not careful.

Final Words

Overall, coffee with milk has varying syns according to the kind of milk that you choose and whether or not you take sugar, for example, one coffee with 30ml of semi-skimmed milk can have around 1 syn, but you can also use milk as your healthy extra A dairy allowance on the plan.

Tips For Making A Low Syn Coffee

To save syns we also suggest avoiding sugar in your coffee and switching to sweetener, choosing low-fat milk over whole can also cut back the calories if you are a coffee drinker.

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.
