I can't find anywhere what it's actually made of (not on the campaign page either). And none of the people listed in the company has any training regarding food or medicine. #slightlyworried Other than that, could be awesome. You could just have a cup with you all day and drink some whenever you feel hungry. Question then remains, why isn't it green?
They do list the ingredients, but not the sources of those ingredients. There are existing alternatives if you want to try liquid feeds but want rigorously tested QAd product from existing reputable manufacturers. Or Soylent, but be aware that it's fun self-experimentation. Here's one of my (grumpy) posts listing alternatives ( https://news.ycombinator.com/item?id=5876219 )
Browsing through the pages: Complan - explicitly states you should have normal meals in addition to the product ("Avoid missing meals completely − you may not feel hungry but your body still needs nourishment") Medifast - want you to eat at least 1 cooked meal daily Optifast - not available for retail (or at least the webpage claims so)
I'm looking for a replacement for the main meal, not breakfasty/lunchy things, which none of these seem to provide. Though perhaps I misunderstand their ads?
