## Reading the bowl properly

Weet-Bix is one of the few breakfasts where the cereal is the small part of the number. Two biscuits are 444 kJ; the milk, the banana and the honey together can more than double it. That is not an argument against any of them, it is the reason logging the bowl beats guessing from the box.

For protein, milk does the heavy lifting: 125 mL of skim adds about 4.5 g. Swapping to 200 mL of milk takes a two-biscuit bowl to roughly 9 g of protein for around 736 kJ.
