@amit shippie
there is no substitute for hard work , castles are not built overnite
u have to go to gym and follow a strict diet to loose fat
divide ur meals into 5-6 small meals divided throughout day
stop junk food and take a high protein low carb diet low salt with lots of fibres
make ur diet chart of what suits u and what u eat
in gym do cardio exercice and do little bit of wt training atleast 4 days a week
take two body parts a day ( like chest triceps , back biceps )
that will help u to tone ur body
btw if ur ht is 162 cm then around 60 kg shud be ideal wt for u
i m 182 cm and my wt is 72kg
