Hi, Welcome to Health care magic forum. 
                      You are 32, 5'1", and weigh 70 kg. For your age and the height you are over weight. The additional reason may be the 
polio, which is restricting your activity. 
                      You can follow 3 steps to reduce your weight. 
                      1)Reduce the calorie intake, fats, fries, and oily foods. 
                      2)Minimize the the sleeping time, by practicing the late to bed and early to rise. 
                      3)Increase the activity by practicing 
yoga and exercises so far they are possible for you. Try to do any work in front of you which you can do.  
                      Wishing for a quick and complete recovery. Thank you.
