Hello, weight reduction is a tough task. Following things need to be concentrated: 1) your caloric intake has to be strictly planned based on your ideal body weight (ibw) which should be 50 kg and level of physical exercise. 2) avoid sweets, deep fried foods, junk foods and pastries, 3) daily exercise schedule should be for more than 1 hour, should include aerobic activity for 20 minutes, stretching and brisk walking 4) set a target of loosing 2 - 3 kgs per month. By reducing 550 k calories per day you can cut 1/2 a kg weight per week, along with above mentioned physical activity. 5) there is no need to increase the dose of thyronorm now, but a periodic tsh levels check should be done.
