We can make a pretty good guess. I found this link on her website: https://justmeat.co/docs/health-dangers-of-a-plant-based-diet.pdf https://justmeat.co/docs/health-dangers-of-a-plant-based-die... A cursory review of her website doesn't reveal any references or links to actual scientific studies of any kind.

However, I found lots of affiliate links to various products. edit: oops, here's a link to her site for reference https://liondiet.com/ https://liondiet.com/
