I've gone on the diet that Giles mentions (Eat to Live by Dr. Fuhrman) and I've also had a significant amount of weight loss, but none of the other benefits Giles experienced (as far as I could tell). There's actually a meal-replacement shake called Shakeology that is made from all-natural ingredients (among others, I'm sure). The two problems I had with trying to replace one meal a day with a Shakeology shake are 1) at $5 a shake (just for the powder), it's really expensive, and 2) after a week or so, I would get ravenously hungry half an hour after drinking the shake. It would be interesting to compare Soylent and Shakeology on a vitamin or even chemical basis.
