Hello I have gone through your question. I can understand your concern. You should know that when you develop hypothyroidism, your metabolism slows down. Your calories start to stick, and your start gaining weight or you may suffer from the inability to lose weight. YOu didn t mention your actual TSH level,this element is important to understand your actual thyroid condition and if you actual dosis of Elthroxin is right or need to be adjusted again. The most effective way of losing weight in your circumstances, would be a combination of diet and exercise to regulate metabolism and burn calories. My suggestions for you are: -Eat e well-balanced diet.Include in your daily meal plan whole cereals, vegetables especially green leafy vegetables, fruits, nuts, whole pulses. -Include Iodine and selenium in your diet because these elements are important for a healthy thyroid function.Natural sources of selenium and iodine include seafood, Brazil nuts, eggs, tuna, salmon. -Avoid white bread, refined flour, muffins, cakes, rich desserts etc. because these cause excess glucose in the blood, which gets converted into fat. -Eat slowly to help digest your food better. -Drink 10-12 glasses of water in a day. -Exercise daily for more than 30 min because a normal body starts losing weight after 20 minutes of exercise, whereas a body with hypothyroidism takes longer. -Try to control stress Hope this information is helpful. If you have other questions feel free and ask. Best regards.
