Yes, you can be successful on the Anti-Estrogenic Diet or the Warrior Diet without taking the supplements; however I would suggest finding some good multi-vitamins somewhere. Supplements are designed to fill a nutritional void in the typical diet. Nutritional deficiencies are common in today's world. The nutritional value of plant foods today pale in comparison to their equivalents hundreds of years ago.Unfortunately, even the veggies and fruits that we eat today are not sufficient enough to satisfy the body's requirements for essential nutrients (see my blog - "What's Wrong with Our Dirt"). In order to control cravings and maximize your body's ability to burn fat while functioning properly, it's important to make sure that your body has been provided with complete nourishment including all the right minerals, trace minerals, vitamins, anti-oxidants, detoxifiers and hormonal supportive nutrients in the most bioactive form. A deficiency of even one essential nutrient, be it a single vitamin or a trace mineral can cause serious metabolic setbacks, with a compromised capacity of the body to utilize food and generate energy. Our line of supplements was specially designed to do just that; support the body's demand for essential nutrients as well as hormonal and immuno supportive compounds for reaching a peak energetic state and a vibrant metabolism. That-s not to say that if you eat foods listed in the diet, respect the proper food combinations and get some exercise, that you won't see some good results, but then again why settle for good when you can reach excellence.
