In my opinion they are both in the throes of an ED, they have both gotten thinner and thinner over the years, but they call it healing...
Veganism unfortunately attracts a lot of people with pre-existing EDs because it's very restrictive and has a reputation (not always earned) as being the best for weight loss or control. Freelee, who is batshit insane, was seriously anorexic before she invented her batshit insane 'vegan' banana diarrhoea diet. Fancy, a person who is obsessed with being very very thin, inventing a laxative fruit diet that causes bowel purging. Shock!
It doesn't shock me either that so many vegan YTers turned to other batshit diets, like going full bore carnivore, raw meat-eating, total plant-hating, fibre- eschewing stuff. One, it's extremism and outrage that drives the algorithm and gets the clicks. Secondly, people looking for diets as cure-alls tend to bounce from one extreme and restrictive option to the next over the years. I know someone like this IRL. Years of bowel issues, probably some form of IBS, and she has gone from growing her own beansprouts ethical and health-obsessed vegan to full on raw milk-obsessed, raw meat eating, plant hater in the past three years since following some carnivore loons on YT and now claims the all-meat diet is the only one for all humanity and all disease is caused by wrong diet, specifically plant-based ones. She tends to extremist positions on everything though, so it's simply a reflection of how she deals with reality, needing tight little boxes to feel secure. People with this mindset seem to always need a highly prescribed, prescriptive diet that is 100% out of tune with mainstream food cultures to feel special and secure for some reason. It's a cultish mindset. Food and diet as defining social identity.
