I've always believed that diet is 80-90% of the fitness equation.  So much so, that I started a to-go healthy foods company (Lithe Foods) so that my clients could eat well and really feed their results. 

We sold lean, local and seasonal fare out of our fitness studios. I developed many recipes, did a lot of R & D, worked with great chefs, a nutritionist, and I also drank a shit-ton of cold-pressed juice.  For five years, juice was a part of my everyday (multiple times a day).  I loved it and truly believed in the power of juicing.  And, I still do.  But, everything in moderation, right? 

For many reasons (beyond juice) my body was very different back then.  And I weighed a lot more than I do now.  I can only imagine how many calories I was drinking per week!  I'm not at all anti-juice, but I strongly believe that the right vegetable blends are absolutely key.  Now, for me, low sugar, vegetable-based smoothies are what I'm drinking everyday for health.
