FULL STOP BOWL

£17.99, fullstopbowl.com THIS ‘ unique’ bowl comes in the shape of a human stomach and is meant to hold about the same amount of food ‘ as your stomach requires to feel full’.

You’re advised to use it for all three meals a day. It actually holds 300ml — about the same as a soup bowl filled about two-thirds full.

EXPERT VERDICT: This is very unscientific, as it’s very individual when you will feel full. Fullness will also vary depending on how much fibre or protein you’ve eaten — and the stomach can hold 75ml to 1.5 litres depending on the person.

The calories served in this would vary a lot depending on the meal. I suppose the stomach shape might make you think more about how full you are feeling, but I can’t see how this is meant to work for everyone — a tall man will need more food than a small woman, for example. 2/10
