“We’re going to reveal the major signs of gluten sensitivity,” promised Dr. Oz on one of his shows several years ago. His first sign: weight gain. “It’s not just eating the gluten that makes us heavy,” Dr Oz claimed. “When you have a gluten sensitivity, it’s really getting your hormones out of whack, and that then leads to inflammation and swelling.” This makes you “hold on to fat” that you should have burned off, he told his viewers. “And even if you go on a diet, if there’s gluten in there, you don’t lose weight.”
