I tried it three years ago as part of my preparation for my first double century and finished it on a plain re-fried beans burrito for lunch and 5-6 UCAN bars. I was using it to loss some weight after being injured but stalled after 5-6 months. Performance-wise, I never recover to pre-injury level and was 10-20% below. I quit after 18 months experimentation and went back to my low carb life style. My experiment falls in line with Kolie Moore's podcast.
