Notice how she doesn't actually list what she ate, the quantities of what she ate, how often she ate, ANYTHING. She doesn't mention what supplements she was taking, if any.

We have no evidence whatsoever she was actually ever a vegan. Her diet was not being monitored. She provides no blood test result scans (even though she claims to have been a vegan for 17 years). None of the prescription slips for these drugs she claims to have been prescribed. What doctor would prescribe such drugs without doing a blood test? What was her weight, as recorded by a medical professional?

There is no reason to believe this person was ever even a vegan.
