Not that I mind. I'm a backer of Soylent. When my month's supply arrives, I'm looking forward to living on it 100% for 30 days for a few reasons:
1) I need to lose a bit of weight. I know that for me, the best way to do that is to significantly change my "generally good but occasionally indulgent" diet. I know from experience that I can't willpower that into happening. But, I think that if I commit to a defined, strict diet, I stand a chance. Soylent should be particularly good for that because supposedly it won't leave me with carb/protein/fat cravings like every other diet I've tried.
2) I like the idea of going on a cleanse. What better cleanse than supposedly exactly what your body needs and nothing else?
3) I'm interested in the chemical science vs. mystical vitalism theory of nutrition debate. I.e. do we need certain chemicals or do we need "something to do with Real Food" to thrive? Supposedly, people feel really fine living on Soylent. I want to see for myself first-hand. I plan to get my "blood work" numbers measured before and after.
