according to the height and weight you have mentioned i don't feel that you are overweight in anyway let alone being obese. so you don't need to lose weight. some other problem may be causing this issue, get it checked out by a physician and seek proper treatment. exercise daily and increase the intensity gradually.
eat a well balanced diet.
drink lots of water.
avoid junk foods and carbonated drinks.
