Starting in the early 2000s, celebrity chefs like Jamie Oliver began promoting an overhaul of the lunches schools offer, but the movement's highest-profile proponent turned out to be Michelle Obama , who made children's fitness her official project as first lady. Their efforts culminated in the Healthy, Hunger-Free Kids Act signed into law by President Barack Obama , which directed the USDA to renovate school-meal nutrition standards for the first time in 15 years. Levine, however, has learned not to be too optimistic: "It's a good idea, there's nothing wrong with it. But again, to my my mind, the opportunity to do what she's saying to have healthy school lunches is limited the problems of the school systems and the budgets. The real takeaway from history is that a healthy school lunch depends a lot less on what individual choices kids make or the particular foods in front of them, and is really about the social and political decisions we make about how we want to feed our kids and how we want to pay for it."
