A post by a computer programmer turned health advocate blogger (attention, Rob), makes a convincing case (in two posts) for avoiding carbs, summarized by him in the subject line. I find these carbs in Soylent.
Last summer, this subject was covered well here:
IMHO, the best grip on a hack was from @atheist4thecause, who sips his Soylent meal over an extended time, to reduce the Glycemic Loading/Insulin response.
From a post in that thread by @MentalNomad, I understand that some carbs are present to powder the oil, and yet addition carbs are present to push the carb ratio higher. Is the higher carb % really needed? Would not the ulimate mix be using carbs, but only to meet the optimum fat/protein percentage? To do otherwise increases the risk of provoking an insulin response, which seemingly benefits no one.
