If you just want to save time but the Soylent thing creeps you out, try this: stop eating as often. I've been eating in a 5-hour window every day (5pm-10pm) and basically save 2 hours a day: I have no need for breakfast and have replaced lunch hour with a HIIT workout. More and more people seem to be doing this as well [1], so it might be a bit more trustworthy than some dude's magic all-in-one concoction.
