A Protein-Sparing Modified Fast (PSMF) is a tool designed to kick-start rapid weight loss by minimising carbs and fat while supplying the body with adequate protein. This approach mimics the rapid weight loss benefits of fasting while preventing the loss of lean mass. It's an extremely effective way to improve insulin sensitivity and break stalls. Bestselling authors and low-carb advocates Craig and Maria Emmerich give you the science to support this method, along with recipes that are incredibly satiating even though they are very low in energy. You will be amazed at how good they taste, too!
