Cochrane's review: new evidence on how the size of food and drink packaging, portions and tableware are leading us to overeat

A new systematic review led by researchers at the Behaviour and Health Research Unit (BHRU), published on the 14th of September in the Cochrane Database of Systematic Reviews, has found the most conclusive evidence to date that people consistently consume more food and drink when offered larger-sized portions, packages or tableware than when offered smaller-sized versions.

The size of this effect, based on combining data from 61 randomised controlled trials (6,711 participants), suggests that if sustained reductions in exposure to large sizes could be achieved across the whole diet, this could reduce average daily energy consumed from food by up to 16% among adults in the UK.
