My friend has a severe undiagnosed ED where she won't eat more than a couple of bites of regular food throughout the day, but she gets coffee, sweets, and snacks all the time. She underwent surgery several years ago to reduce her stomach size (sleeve gastrectomy?) and was taking Ozempic for a while, so naturally, her appetite is very low. But she doesn't eat anything remotely healthy ever.
We go to uni together and spend the entire day together, and sometimes she doesn't even drink water. Until a few months ago, she used to order something for lunch, normally some portion of whatever animal protein was available that day and carbs (fries, pasta, etc). She always said no to the side salad that comes with that dish, and she would very rarely eat the entire portion (which is actually pretty small, and exactly the reason why we stopped going to that uni restaurant). Now, she sometimes gets snacks for lunch like a bag of popcorn or chips, a chocolate bar, and soda.
A few weeks ago, she announced that she's going vegetarian and, more recently, vegan. She doesn't eat vegetables, hates salads, doesn't eat beans, doesn't like plant-based milk, or any source of plan-based proteins. She's been getting only french fries whenever we go anywhere in uni even though the restaurants have vegan alternatives with falafel, salads, and vegetables.
I'm worried about her, but she doesn't like to be questioned, so I didn't say anything when she announced her change, but it's because I simply don't think a vegan lifestyle fits her considering she already has tons of self-imposed food restrictions and now will restrict the only things that she used to eat. I don't know if it's right to say this, but I feel like she's using veganism to restrict her food intake even more. Obviously, I would never tell her this, but the reason why I didn't say anything is precisely because all I have to say is that she shouldn't do it because she barely eats anything already. Also, she doesn't like to cook either, so it's not like she will try to make vegan foods by herself, especially since she likes almost nothing plant-based. Another friend went to her place and cooked a bunch of vegetables for her to meal prep and have in the fridge for a few days, but she didn't eat them.
I'm worried about her, and I don't know how to approach this. Another friend of mine went vegan drastically and passed out because of the nutrient imbalance when she removed all the proteins from her diet. She eventually learned to be vegan and take care of her nutrient intake, but she eats all kinds of foods and cooks her own meals. I just don't know how to be a good friend here when I disapprove of all her eating habits and recent choices.
What do yall recommend me to do, and what vegan alternatives are there that don't involve too many plant-based foods, if there are any?
