Getting food delivered sure is convenient—but it’s also a surefire way to gain weight.
According to a study in the journal Management Science, if you place an order on the phone or online and have it delivered, you’re likely to buy about 100 calories more food than if you order it in person.
It’s the anonymity of not having to face a (potentially judgmental) server that frees customers up to pile on the extra food, researchers concluded.
