How Many Syns in Cornflakes?

Cornflakes are one of those classic breakfast cereals that nearly everyone has reached for at some point, and on Slimming World they sit in a genuinely useful spot thanks to their Healthy Extra B status. A 40g portion of plain cornflakes counts as a Healthy Extra B choice, which means you can enjoy a proper bowl alongside your skimmed milk Healthy Extra A and a heap of fresh fruit without dipping into your daily Syns at all. That makes them a brilliant option for busy weekday mornings when porridge feels like too much effort and you need something quick, crunchy and reliably satisfying before you dash out the door.

Where cornflakes get a bit trickier is when you wander beyond the plain variety. Frosted, honeyed, chocolate-coated and crunchy nut versions are all coated in extra sugar or syrup, which pushes the Syn value up considerably and means they no longer qualify as a Healthy Extra B. The same goes for going over your measured 40g portion: anything beyond that allowance is counted as Syns at roughly 3 Syns per 30g, so weighing your bowl really does matter if you want to stay on plan. A digital kitchen scale is your best friend here, because the difference between a tidy 40g and a generous eyeballed pour can be significant.

To keep cornflakes feeling like more of a treat, pile on the fruit. Sliced banana, a handful of raspberries, blueberries or chopped strawberries bulk out the bowl beautifully and add natural sweetness without any Syns. A spoon of fat-free natural yoghurt on top works wonderfully too, adding creaminess and a little protein boost. Used wisely within their HExB allowance, plain cornflakes remain one of the easiest, most flexible breakfasts on the plan.
