Harley Pasternak has updated the body reset program to include the latest finds in nutritional science, new recipes, and shopping lists, offering readers a chance to slim down, gain energy, and get healthy in fifteen days, then stay that way. The focus is on blending, which the author suggests is the simplest, most effective way to slim down. A five-day jumpstart includes smoothies, dips, snacks, and soups, all customizable to any preference or diet restriction. Over the following ten days, readers reintroduce healthy versions of their favorite foods along with the blended recipes. The book explains how the easiest forms of exercise, such as walking and some light resistance training, are all it takes to achieve your goal.
