hi anu pama,
my story matches alot with u ..just i am little heavier than you...but trust me like yours my body tendency is also of not reducing weight .I did everything like excercise,dieting, but nothing helped me.now i believe in one thing..its important to feel healthy and you legs should be comfortable carrying your body weight may be you may loose weight after some more months
.so as a good friend a piece of advice for you.. dont take tension ....dont overstrech yourself and mainain the same healthy life style ..i am sure you will enjoy life being healthy and fit.take care
