Do Larger Portion Sizes Lead to Overeating?

Larger portions, packages, and tableware lead to higher consumption of food and drink, a Cochrane review has found (Hollands et al., 2015).

The research said that eliminating larger portions from the diet could reduce energy intake by up to 16% (roughly 279 kilocalories a day) among UK adults or by up to 29% (roughly 527 kilocalories a day) among US adults.
