This is from a few pages back, but this comment reminded me SO much of Ruby Gettinger, that red-haired woman who had her own reality show ("Ruby") from 2008 - 2011 or so. At her highest she was around 700lbs and during the TV show she got down into the 300's and she felt positively skinny at that weight, flaunting herself around and saying "I'm skinny now!" Ruby reminds me sooo much of Amber in her mannerisms, too. Pronouncing words incorrectly, being obnoxious, guilting her enablers, etc. IIRC her show was cancelled because she never made consistent progress with her weight loss and admitted to binging whenever the cameras left. She also talked about how she learned how to lean a certain way when she did her on camera weigh-ins and she could shift the scale by 30-50lbs by doing so.
Edit: Ruby also claimed to have NO memories before the age of 13, which is when he said her weight loss problem began. She and Amber should be BFF's with how they play the troubled childhood victim card.
Last I heard she is still active on social media trying to "inspire" people to fight their battle with weight loss, while she remains just as fat as ever. Amber will be headed down a similar path of never succeeding in consistently getting healthier unless she loses the attitude/completely changes her personality.
