Hey Mark, welcome to the forum! First things first I would recommend reading this post I shared a while back. It gives a breakdown of my advice for a new person trying Huel and wanting to lose weight.
In regards to which product, that’s really down to personal preference. However, we have a useful webpage here which might help you out.
But we also have a little questionnaire here which might steer you in the right direction.
Have a look and let us know if you have any other questions, we’d love to help!
