My stomach definitely kept working, but I started getting some stomach aches and other weird symptoms which repeatedly went away after multiple tests of 1-2 weeks without Huel. It took so long to figure out though because I realized that I got the same symptoms from consuming palm oil. So I ruled out Huel for a bit, didn’t really have an effect because I still kept consuming palm oil, eventually tested ruling out both and I’ve been feeling much better ever since.
There’s simply some ingredient in Huel that don’t work so well with my stomach. I’ve started trying hot and savoury after 7 months without Huel and so far so good. I’ve had 3 meals so far during 4 days, starting off slow. I see it more as a last resort food which works great considering the long shelf time.
