Tosca Reno is the author of the Eat Clean Diet and its basically eating non-processed, whole foods. What makes this "diet" hard (its not really a diet) is that you have to tote your food with you wherever you go and do a lot of prep work. Once you do that, then you always have clean food at your disposal. I have tried it and it does work and it works fast. Good way to clean our your body and drop pounds.
