Ann Louise Gittleman, author of "Radical Metabolism," explains why people get “stuck” with impaired metabolism. She shares a novel take on the role of the gallbladder in detoxification; impaired gall bladder function—or its removal—hampers a key pathway for optimal metabolism. Ann Louise is a fan of coffee, hibiscus and oolong tea, bone broth, and a concoction she has named “Citrus Blaster”. She has devised a 4-Day Radical Intensive Cleanse and a 21-Day Radical Reboot. She shares her journey from Director of Nutrition of the low-fat, quasi-vegan Pritikin Institute to her current advocacy of low-carb dieting with ample amounts of healthy fat—but issues some cautions about the Paleo and Keto diet paradigms. Artificial sweeteners are out—but certain natural sweeteners have a place in Ann Louise’s paradigm. She shares her top supplements—including glycine, l-glutamine, and astaxanthin.
