I've been on DIY soylent on and off since last June, and had a few weeks of bulletproof while I was doing high-protein low-carb soylent.
Bulletproof is nothing like a soylent replacement, it's just like a crazy energy drink. Basically you just skip breakfast and have your coffee whisked with unsalted butter and MCT oil. My experience is that it accentuates the alertness feeling of drinking a lot of coffee but without the wiredness. However, it tastes like ass - coffee with theanine has very similar effects and tastes much nicer.
Also worth noting that Dave Asprey talks a lot of hype - like many non-scientists trying to interpret the literature he tends to find one or two papers that confirm what he was hoping for, and ignores the counterevidence. Talk to your doctor before you start having a stick of butter every morning.
