Portion Sizes

The PEACH lab is interested in understanding whether portion size policies and interventions can be designed to encourage consumers to eat satisfying amounts without mindlessly overconsuming food. Our recent work in this area has focused on sugary drink portion limit policies, like the one proposed in New York City to cap the portion sizes of sugary drinks served in restaurants to 16 ounces. Our research demonstrated that such policies can backfire if not properly designed. Dr. Roberto also teamed up with a public health lawyer to write about the scientific evidence and legality of such policies.
