The Wahls™ Diet plans are designed to improve nutrient density, reduce inflammation, and provide nutrients needed by mitochondria and brain cells to function optimally. The introductory Wahls™ Diet, Wahls Paleo™, and Wahls Paleo Plus™ (the ketogenic diet) are all reviewed. There will also be guidance for vegetarian and vegans who wish to follow the Wahls™ diet plans and those who need an elimination diet.
