she will not... you haven't seen the 90's to mid-2000's south indian actresses and the newer bhojpuri films actresses... they look fine enough.
it is just this capitalist "health and wellness" industry and media industry and useless-phd industry that promotes the gymming-shimming and dieting that have brought the trend of 50 kg heroines ( even 45 !! ) and which prevents many people from seeing what is natural and nice.
look at the lovely shraddha kapoor... she was already slim and she went thinner for her film, "abcd 2", and is now promoting some "healthy green tea" and talking about how she does workout and running everyday... such a waste, because she is beautiful and has such feminine expressions and gestures and voice.
