I'll bite, and I will follow but what Mr. Helton is doing does not seem very thought out. he is an endurance athlete with demonstrably low body fat. There is NO doctor involved but more importantly there is no demonstrable evidence that Soylent is more, better or different than a glass of milk.

But back to body fat:

"...Low body fat levels can lead to incomplete recoveries after workouts; depleted glycogen stores; nutritional deficiencies that lead to further problems, such as bone loss; decreased performance; chronic fatigue; increased risk of infection; and injury, according to “The Complete Book of Sports Nutrition: A Practical Guide to Eating for Sport.” ..."

Is this cool because it's a start up thing? I don't recall anyone going on Ensure binges.
