I would love to follow a Tim Ferriss (well-versed body hacker and author of 4-Hour Body) experiment with Soylent. I've read his book and his analyses convinced me to try a diet for the first time in my life to change my body composition. Now I go through Slow-Carb diet phases a couple times a year. If he had praise for Soylent I'd be willing to give it a try, too.
