The way Niomi manipulates her partners re food is really sinister tbh. She always starts off her relationships pretending she's really relaxed around food or has recently become really relaxed around it. If you look at Joe for example, their first date was a steakhouse. By the end of the relationship, all food at home was vegan, she was telling him off for having toast with his smoothie, he was bending behind a cabinet to hide the fact he was eating a snack, she was hiding his peanut butter, and she was dragging him into health cafes ON HOLIDAY because she couldn't bear eating 'non clean' vegan food. The trajectory is very deceptive and seems like the 'frog boiling in the pot' method.
The only reason Forky didn’t fall foul to this IMO is because he is a PT and while he is dumb in most other aspects he knows he needs a) a lot of calories, which would be hard to get on Niomi’s very limited version of a vegan diet, and b) high protein, which IS easier to get while eating meat, and while it is absolutely possible to eat high protein while being vegan it is not possible on the 'Niomi vegan diet' of mostly smoothies and vegetables. Being with Forky is when Niomi started to relax her diet, although she was also seen eating a lot of meals that contained more animal proteins but no carbs, so Forky had probably told her she would get even thinner if she started eating meat protein. I also think a big factor was the fact Joe moved on with Anna, someone who regularly talked about loving pasta and was being photographed eating pasta, albeit she was also tiny and probably giving it the Tanya Burr treatment.
If she's realising now that her eating is disordered then I'm glad for her but she's subjected several men to this horrible controlling behaviour that flies under the radar because it's performed by a woman. Joe was seen looking a lot healthier after they split so he is probably okay but Marcus said after they split that he had experienced disordered eating, wouldn't be surprised if Lordon was the same, I think we can safely assume Forky has no thoughts in that head of his and is probably fine
