U.S. News's Best Diets 2013 turns the spotlight on plant-based diets, including the Mediterranean, Flexitarian, and Traditional Asian diets. Research suggests these plans promote weight loss, while also protecting against diabetes, heart disease, and other health conditions. We sat down with plant-based dietitian Julieanna Hever, author of the Complete Idiot's Guide to Plant-Based Nutrition. She's also a special consultant for the documentary Forks Over Knives, and hosts the Veria Living Network's What Would Julieanna Do? In this video chat, Hever describes the benefits of going plant-based, along with sample meal plans, and explains how to overcome the challenges of a new eating approach.
