Though I dont share quite the same level of negativity towards the idea (Personally, I think it'd be amazing to be able to give up food for something that is nutritious and safe), I definitely share your concerns.

It is possible that the nutrient powder (and similar) industry hasn't given much thought to this idea because its radical and potentially risky, especially as a business venture where legal liability might be very, very high (all it takes is one person to die or be seriously injured as a result of this drink, and they are in big trouble). I'd say that IF any of these supplement producers did consider this type of drink, they probably dismissed it as too risky (both legally and financially, as I don't see the demand exploding for this).

Also, he's not claiming that he has solved any problem. He's only claiming that after some research, he whipped up this drink, and that it seems to be working fine for his body chemistry. In fact, he's pretty clear about this being experimental and potentially dangerous (Though apparently there have been no negative effects as of now). I think its a really interesting idea, but nonetheless, I'd feel much better if he was a scientist focusing on a similar field. This seems like the exact kind of thing where small, seemingly unimportant details may propagate into significant risk.

I seriously wish him well though. Personally, I wouldn't do much more than use this as a supplement (perhaps to replace lunch), but Im not the risky type when it comes to things like this.

The stuff bodybuilders consume is not as well controlled as anything called 'food'. In fact, bodybuilding forums are full of 'I bought brand X and it was mostly filler, better stick to brand Y'.

Im not thinking about the FDA specifically here. I'm thinking about general wrongful injury (possibly death) lawsuits where someone becomes seriously ill from consuming nothing but their "magic soylentesque shake".

Marketing it as a food replacement would be very difficult because of subtle differences between people's bodies. I think they stick with supplements/protein powder because it reduces the possibility of wrongful death lawsuits (and similar) while still allowing leeway with federal regulations.

That's simply not true. They have to list the nutrition info the same as any other food. Protein powders that are "mostly filler" are actually ~20% filler, not mostly. And the label makes that quite clear as it both lists the ingredients so you even know what they are using as filler, but also the nutrition info. If 30g of powder is only giving you 20g of protein, obviously there's 10g of something other than protein there.

It may also be the case that "drink one of these a day and lose weight" is more marketable than "drink one of these a day and never eat real food again" ;)
