I'm flirting with the idea of anteing up and ordering some for myself. Currently, I'm on a weightlifting binge, and those macros looks realllll nice. I typically use Muscle Milk (so bro, yo) to supplement my protein intake, and the macro ratios are similar. The Soylent has better micronutrients, but more carbs. I also find myself lamenting my need to eat and hate the prep and cleanup, so I usually eat out. I'm thankful to have a salary that allows me to do so. I really like unsweet iced tea, but everyone down here in the South will screw up your order and give you sweet tea. Convenience stores don't even stock unsweet tea of any kind. It's like everyone wants to give you diabetes. Hopefully they'll put out a Soylent mix sans sucrose sometime in the future.The drink could stand to be less sweet.
Muscle Milk is nearly 50% protein and like 15% carbohydrates, soylent is less than 30% protein and nearly 70% carbohydrates (without the oil packet). That doesn't seem very similar to me. Soylent, for me, is waaaay too heavy on carbohydrates. Which is sad, because it's convenient enough to be worth the price for me if it had more appropriate macronutrient ratios.
It still has better macros than the vast majority of Americans' diets... what a low bar that is, though. But you're absolutely right. Too many (presumably simple) carbs.
