CALORIE-COUNTING BOWL

£14.99, thediet plate.com COLOURED concentric circles inside this bowl depict the fill level for several cereal brands — the lowest ring is for energy-dense muesli or porridge oats, and the highest for puff- style and flake cereals.

Most people are shocked when they see a correct portion of cereal — the right amount of muesli is around 45g, but most people would eat more like 75g, an extra 100 calories. Using this bowl and adding 125ml of semi-skimmed milk limits you to 200 calories — with fruit, that’s still a very slimline breakfast.

It can be used to portion soup and desserts as well, but weighing your cereal and seeing where it comes up to in your usual bowl would be almost as good. 7/10
