What really annoys me about her qualifications, is that a quick Google search comes up with several pages claiming she has a PhD. I know she's told the story about dropping out, but there's an awful lot of reference to it.
Here's a related example;
I'm not knowledgeable about how influencing works, but this seems to be some kind of agency website. It references her being a Lulu ambassador (below where I've taken the snip) so recent info combined with the fact she's a science student at a London uni, which she obviously hasn't been for a number of years!
My degrees are very close to the ones she completed (and didn't!). She's definitely stretching to relate it to fitness. Yes, I studied basic physiology and anatomy - and I sometimes read papers on this stuff and get the message. BUT my big beef with her, is that there are people out there doing academic research into proper exercise physiology who are the experts. Why is she speaking for them? Why is she the face of exercise/dietary science?
Totally agree with others about the back injury being a big turning point, I thought she was OK upto then and it seems something has changed with her content style or her attitude since.
