Your bmi is 31.54 kg/m2 showing grade 1 obesity. I am not aware what all the measures you have done to reduce weight. Please give details of thyroid test report, let me see that. Secondly your diet has to be based on (for caloric value) on ideal body weight that is 60 kgs, since you want to cut weight your total intake has to be very well regulated. That means daily calories should be restricted to a maximum of 1200 to 1300 kcal/day.
Plus you will have to exercise for at least 1 hour. Brisk walking, aerobic exercise, jogging, skipping and swimming are to be undertaken. This has to continue for at least over a period of 3 to 4 years with same intensity. You should aim at a reduction of 5 to 8 % of present weight, initially.
