Not thyroid: The most likely answer is that your thyroid is not at all the culprit. Analyzing your caloric requirements and physical activity will most likely reveal that your balance of calories in is greater than calories expended per day and is leading to a slow and steady rise in weight. It's certainly possible that another endocrinopathy is present (cushing's disease, eg) but unlikely.

Probably not: Due to thyroid. What is free t3 (liothyronine). That is hormone free to act in body. If it is low then you are still low. But doubt it. You are just taking in more calories than your body needs to function. Either eat less or exercise more.
