1. I am gluten intolerant, so swap out oat flour for almond flour. Swap out B complex supplement for marmite. Also, calling marmite "real food" is a bit of a stetch in my estimation.

2. After the first week, realized I was probably mildly allergic to casin, swapped to coconut milk.

3. After the first week after that change, noticed I am probably also mildly allergic to banana. Cut it completely.

So what I ended up with was a high fat low carbohydrate equivalent that isn't too bad. I actually drink this pretty regularly, and it is extremely filling. However, calling this guy an idiot is disingenuous to say the least; his work is going through considerably more scrutiny than Soylent Orange, and it contains considerably less allergens. Depending on who you talk to, up to 15% of people are gluten intolerant[1] and so, when keeping risks in mind, we should be cognizant of the dangerous of various proposals.

All in all, I actually do like (my modified) Soylent Orange, but ad hominem attacks are unnecessary and "real food" is a suprisingly slippery concept. Hell, coconut and almonds are common allergies too!

I already basically live on milk-based shakes now, and it's a pain having to replenish my milk supply twice a week. Soylent would solve that nicely.

All you are pointing to is an alternative solution which basically has all the same issues in getting the right mix of nutrients, and more work on the consumers part. Convenience is at least part of the appeal of Soylent.

Fine, you prefer that approach, fair enough, there's no data that says it's the better one.
