Because nutrition is a crucial part of any wellness program, we have found significant results with our clients who subscribe to this diet regime that is specific for their blood type. By adhering to the principles of eating particular food groups that are considered either beneficial or neutral and not eating those that are on the avoid list, a person's health is dramatically improved. This way of eating is different from virtually all other diet books, which tend to only classify foods by their macronutrient content, such as 'low carb' or 'low fat'. In choosing this way of food intake, not only can you loose weight more easily, but you can increase the strength of your immune system and overall vitality. There are specific vitamins designed for each blood type that work synergistically for males and females.
