A team of researchers from Cornell University surveyed 501 females between 20 and 35 years of age, asking questions about cooking habits, weight and height, and how respondents found new recipes. They learned that when it comes to cooking shows, there are two kinds of people—“viewers,” who merely watch food on TV, and “doers” who try the recipes they see on cooking shows. The study found that “doers” had higher body mass index (BMI) than those who merely viewed—and that, on average, they weighed 11 pounds more than their non-cooking counterparts.
