There's nothing wrong with her putting on weight. The only issue I have with those pictures is that she looks as if sje may be putting her health in danger. I don't mind weight, but when it puts your personal helath at risk, it's better to be on the thinner side. Not the stick she was before, but slimmker than she is now.
there's nothing wrong with going from being the human stiuck to a healthier weight, that's normal and fine.
It's when you start creeping into overweight and obese, which by the looks of the 2nd chin on Tammy she looks like she's doing, then cioncerns about weight and health and disease risk should be brought up.
