I would have said same. She's already been diagnosed with Type 2 beetus but  also underwent  bariatric and is the only one who makes any noise about losing weight. Metz is the oldest and most  comically round at this point but she has yo-yoed  significantly and I think some sort of nominal weight loss is in her TV contract.  She also interacts with non-whales on a pretty regular basis which may serve as a tether to reality. I have to go with Tess. Youngest by a couple years but she's so ensconced in HAES culture and fat fetishism I can't imagine her even going to a sane doctor. And that feeder hubby of hers sure isn't speaking up even when the toes start twisting off.
