Chef and TV personality are just a few of the jobs that Devin Alexander has on her plate. Passionate about creating a healthier lifestyle for as many people as possible, Alexander is involved in everything from sitting on the board of the American Culinary Federation’s Chef Child Foundation to lending a helping hand to Michelle Obama’s Chefs Move to Schools Program. As someone who battled weight issues herself — and has maintained her 70-pound weight loss for more than 16 years — she stays true to her mantra: You don’t have to deprive yourself to be fit and healthy. She channels her experience and love for cooking into helping the contestants on The Biggest Loser and through her eight cookbooks. Her newest show, America’s Chefs on Tour, debuted in late 2012. Alexander is also working on a food line, Devinly Delites.
