AMNA21- you are already a healthy weight, and the amount of weight you want to lose and the time-frame to do it in is unhealthy.
"I started to use traedmill for 4-5 times per week ( speed 5 to 6 km/ hr) range from 1- 4 hours."
THIS is also very unhealthy. No-one needs to exercise to that extreme - and up to 4hrs in a day, IS very extreme.
I strongly suggest that you make an appointment with your Dr and talk with him/her. If you find it rather difficult to verbalize to your Dr, take a printout from your original post here, and allow your Dr to read it., because I strongly suspect that there is a lot more going on with you than meets the eye. I feel that you could benefit from some counseling with a Therapist who specializing in weight issues.
