I have experienced great success with the Schwarzbein Principle, as it is more than a diet, but a way of life. It is based on a five-step method of healing the body through natural means. Step one is healthy nutrition. The emphasis is on consuming whole, unprocessed foods. Meals are built around protein, and drinking plenty of water is essential. Step two is stress management, which includes adequate sleep and downtime. Step three is to avoid toxins and chemicals, such as artificial sweeteners, alcohol, and caffeine. Step four is a cross training exercise program that involves flexibility, resistance, and cardiovascular training. Step five is hormone replacement therapy if needed. The Schwarzbein Principle focuses on achieving a healthy metabolism and body composition. What I love about this particular diet is that it focuses on getting the body to a healthy place where it can burn fat effectively. You are taken through each step slowly enough that this becomes a sustainable way of life rather than a diet that you follow then ditch. Effectiveness Great principles for daily living. Side Effects A cleaner colon and detoxed liver are the only side effects. Ease of Use You are taken through this plan in easy to manage steps that can be followed for the rest of your life.
