Yeah, I even wrote a paragraph bashing it (or at least, people claiming that it's a product of serious medical research) last time we had a Soylent thread. It has a lot more sugar and carbs than most people would want to eat regularly, which makes it more suitable as a temporary food replacement or a snack than a lunch staple.

Try something like Glucerna. It's like Ensure but for diabetics, so it has a lot less sugar and carbs.
