Using smaller plates helps stop people overeating. Many people use a large plate and they fill it with food. This means they eat too much. Cambridge University says if people use smaller plates, they will eat less. Americans could cut their calories by up to 29 per cent.
The researchers looked at many people. There was not a lot of research on food sizes and how much people eat. It is wrong to think that people who eat too much have no self-control. Restaurants can help to stop over-eating by using smaller plates. People can also do this at home.
