That's an excellent question, I've been trying to pry an answer out of several people. At the beginning, I had a consultant who had a nutrition degree, which was great, I trusted what she said a bit more even though she was fresh out of college and it was her first job, but... as you'd imagine, she was 'promoted' to run a different center i think.
From what I can tell about the rest, they hire based on willingness to learn, sell, and people skills, not any particular background. One that I see often used to work for a vitamin manufacturer (sales) and another used to work as a bank teller. I would imagine they go through basic on the job training and given the lack of sophistication in the marketing materials MRC provides them to explain things to us (ie the flip boards, the brochures, the class hand outs), I doubt the materials they use to train their own employees are a) thorough and b) includes scientific data.
Example, I did the hormone testing for $200 a while back after several of them said i should because my losses didn't make much sense. So frustrated during a plateau, I did it and when they walked me through the results, it sounded like a very shallow understanding of the hormones without any background of how they work together and the answer to a lot of it was 'our cream will help with that'.
So, overall, I hate to say it but I don't trust or take advice from them regarding my overall health or something that I would expect a person be trained on before they speak. I DO however trust their anecdotal information like "lots of people I talk to find that.." because they do talk to an awful lot of us every day, so I would imagine it's easy to see some patterns and get ideas.
Hope that helps. I think it's a bit hit or miss, you may find some have nutrition degrees but most don't.
