My daughter is insisting she's on OMAD with less than 100 calories a day and no exercise. CW: anorexia

Need advice and resources.My foster daughter is 17, 5'8", and 150 lbs. She's somehow gotten it in her head (thank you TikTok, her mom, and her mom's boyfriend) that she is a fat disgusting pig if she can't see her ribs.She's had less than 100 calories each of the past 5 days, and skipped a few days prior to that. I talked about healthy ways of fasting (I'm on IF 18-6, lost 60 pounds past 14 months) and she insisted what she is doing is OMAD.She's so lethargic she cut school to sleep in the library and fell asleep tonight with a lit stove while making her dinner (refuses to eat anything she doesn't make herself).I'll take any advice I can get. via /r/intermittentfasting https://ift.tt/Z64FIa0 https://ift.tt/B5aHLRx
