I have a strong belief that an attempt to eat right and treat your body right is better than not trying at all. This goes for the countless dieting attempts that people make and possible fail. In my eyes to fail is a success in itself. It failed at least you tried.
So one of the diets out there is the Smoothie Diet. I think this is a great option as it ensures you are getting the nutrients you need while cutting calories. This is a 3 week program that helps you along the way with coaching.
