ALR seems very motivated to lose weight and eat "clean" these next few weeks leading up to surgery. ALR inadvertently shaded Chinny by saying she couldn't imagine gorging on fast food before the surgery, and that she felt she had to be as healthy as possible before going under the knife. So the complete opposite of what Chins did. IMO, it seemed like ALR was just simply stating the obvious and not deliberating trying to shade Chantal.
It will be interesting to see Jabba's reaction, if any - both to the fact that ALR's getting a hysterectomy soon and to the drastically different approach ALR seems to be taking pre-surgery. Amber also spoke about wanting children if she ever got healthy, and mourning the loss of that possibility. That could trigger Chinny also. We all know how she likes to copy Amber, after all.
Amber getting the hysterectomy, taking all of this as a wake-up call, losing a chunk of weight, and taking a completely different path than Chantal seems like it would push Chinny over the edge.
