This blog post by Jonathan Margolis in the Financial Times is pretty positive about Huel, and has a quote from Julian Hearn. (But it does stereotype Huel’s users a bit.)
However it is behind a pay wall, I wonder if anyone knows of a non-pay-wall’d version?
Oddly, clicking the Google search result for Liquid lunches — with pea protein ft has allowed me to read it ([edit] but only the first couple of times, now it’s paywalling me)
If that doesn’t work, perhaps selecting the cached version will (clicking the little dropdown arrow to the right of the first Google result’s URL and selecting Cached) ([edit] this still works)
Nope, I think they’re on to me now 
even if I use the link from the Google Alert where I originally found the article, it goes right to the pay wall. Wait, let me try a different browser… hah! the Google Alert link still works from a different browser (Safari: different cookie stash I suppose).
Alas, I don’t see any dropdown menu for a cached version there. If you can get a link to a cached version, post it here!
BTW, be sure to read the comments on that post – a whole lot of people do not get the concept at all!
I managed to view a Google Cache version here: https://webcache.googleusercontent.com/search?q=cache:MWrpSD6Aa7oJ:https://www.ft.com/content/27433998-28ee-11e7-bc4b-5528796fe35c+&cd=1&hl=en&ct=clnk&gl=uk
