BoBerry lost weight after her father died and her therapist encouraged her to change her lifestyle, and the lockdowns didn't help. Now she's traveling around and living it up. She actually looks like she's gained back some of the weight she's lost, but it's anyone's guess if she'll cross 600 again (and if she does, she might not look as puffy, unless she gets to 650).
Adeline gained a lot after injuring her leg, which has since healed, and according to her got gallbladder surgery. Assuming it's not a cover for WLS, she definitely wasn't going to be able to eat the way she did to put on 100 pounds, which is already no small task if you're over 600 already. She might not be able to eat that way for a long time, but fingers crossed it won't be forever. You're forgetting the kind of ingrained habits it took for her to get to 600 in the first place, and that will take hold when her appetite returns.
Jackie I honestly think is only stagnating for her wedding, but after she ties the knot she's going back to her old diet of absolute garbage. She loves cheese and cheesy things and those tend to be the fattiest foods. I don't think she has it in her to keep to any diet since she's all for HAES and that whole intuitive eating biz.
Keep the faith. We saw heaven and we may glimpse upon it once more.
