Stuck at home with no place to go coupled with the stress of a worldwide pandemic have caused many US consumers to put dieting on the back burner, except for dieters on keto and other lifestyle diets, like gluten-free and clean eating, reports The NPD Group. US adult participation in total diet or nutrition programs dropped from 48.3% in April 2019 to 43.8% in April 2020, while participation in the keto and other specialty diets remained unchanged in April from a year ago, according to NPD’s Health Aspirations & Behavioral Tracking Service.

NPD’s How Consumers Define Clean Eating report shows that 61% of primary grocery shoppers feel packaged foods are acceptable when eating clean, and 44% of shoppers say some processing is also acceptable.
