Does White Bread Have A Lot Of Syns?

If you are a lover of white bread compared to wholemeal then you will need to count its syns on the slimming world plan according to its size and brand.

On average, a slice of white bread on the SW plan is around 3 syns, but it could have anything up to 6 syns if you get white bread which is thicker. 

Down below in our guide we will go over how many syns different kinds of white bread have, which type of bread is syn free and some syn values of white bread according to different brands.

Why Are Syns For White Bread Different?

As we mentioned above, white bread syn values vary according to their weight, for example, thinner white bread of around 400g is 3 syns per slice, but an 800g thick loaf will cost you 6 syns.

We've listed out the varying syns for white bread according to the size below.

  • White bread 25g slice - 3 syns.
  • White bread 400g slice - 3 syns.
  • White bread 800g medium slice - 4.5 syns per slice.
  • White bread 800g thick slice - 6 syns.
  • White bread 800g extra thick slice - 7 syns a slice.

Which Bread Is Syn Free On Slimming World?

You might have heard some bread is syn free on the SW plan, this is not completely true but brown bread can be used as your Healthy extra B, meaning that it counts towards your fibre allowance and doesn't have to be used as syns.

White bread has less fibre than brown hence why its syns have to be counted, although there are a few types such as Kingsmill great white which can be used as your Healthy extra B due to its extra fibre.

We've listed a few of the brown bread types you can use as your Healthy Extra B down below.

  • 1 Hovis Wholemeal Sliced Roll.
  • 1 Warburtons gluten-free multiseed sandwich thin.
  • 3 slices Kingsmill No Crusts Wholemeal Bread (400g loaf).
  • 60g wholemeal bread.
  • 2 slices small gluten-free bread, brown/high fibre white /multi-seed.
  • 60g rye bread.
  • 1 wholemeal roll.
  • 1 wholemeal pitta bread.
  • 1 gluten-free roll, brown/high fibre white/multi-seed.
  • 1 thick slice wholemeal bread (800g sliced loaf).
  • 2 small slices of wholemeal bread (400g sliced loaf).

Should I Eat White Bread On Slimming World?

Overall, if you can, we would always suggest switching over to wholemeal bread on the slimming world plan as it gives you extra syns to play with and has more fibre and health benefits which can aid in weight loss.

However, if you are a lover of white bread, it's not bad to have the occasional slice as long you are tracking it in your syns, make sure to know the weight of your slice beforehand and double if having two slices.
