<human>: Rather new to this subreddit but I love it and think you guys are awesome. 

I have always been overweight the whole time I have known "Jess" and have talked to her many times about how ugly it makes me feel and how hard it is to try my hardest and still not loose hardly any weight. Jess on the other hand is naturally skinny but sometimes has really down days so I try to boost her self image and tell her she looks pretty no matter what. 

I've recently found out that I find it so hard to loose weight is because of a genetic disorder and spoke to her about this because at the time I was really scared but now I'm on meds to help sort out my hormones and am finally starting to shift some weight even if it's slowly  :/ 

Anyway since this happened Jess' self confidence seems to have done a complete 180 and has sent me what seems like constant snapchats of herself saying things like "yay look so skinny today" or "someone told me I looked like I lost weight woo". As well as sending me pictures of any time she goes out to eat or orders takeaway which is quite often.

I know Jess really well and know she isn't being mean on purpose she's just sometimes a bit clueless/tactless. I love her she's the closest thing I have to a sister but I'd really like to get her to stop without making her feel bad about it but really don't know how.

Can you condense the text into three sentences or less?
<bot>: Bestfriend keeps making insensitive remarks when I find it really hard to loose weight. And want to know how to gently tell her to stop.
