Why are the sisters all of a sudden so interested in weight loss and “bodychecking”?

I’m really curious as to why just recently the sisters have started to lose a lot of weight and have started to put a lot more emphasis on their figures. When I first discovered the sisters back in May 2024, they looked good. After a bit I stopped following them like that as I found other interests to amuse myself. Now with my lack of a steady interest to entertain myself, I started to see what was up with the Kalogeras sisters at the moment and I had noticed the slimming of their figures and it makes me wonder or speculate as to why the sisters are all of a sudden so interested in this and if there is any legitimate reason for concern as to why they would be doing this . (my intention is not to be a fan I just want to introduce a thought and see how others feel about it.) P.S: in no way is this meant to shame the sisters)
