As Thanksgiving’s heaping helpings loom, it might be good to remember both obesity and food waste are linked to your plate’s portions. Hank Cardello is Chair of the Portion Balance Coalition and executive director of the Leadership Solutions for Health + Prosperity program at Georgetown University’s Business for Impact. He joins host Krys Boyd to discuss how restaurant meals and prepared foods have doubled in size since the 1970s – and why cutting them back down would be good for the planet and people. His research paper on the topic is called “The Power of Portions.”
