Too little or too much iodine can fuck up your thyroid (only because it uses iodine directly), but otherwise it's not real sensitive to lifestyle or diet... however it can influence what you want to do and eat (low thyroid causes sugar craving and lack of motivation/energy to do anything). TSH levels fluctuate depending on iron, selenium, and sugar intake, but there's no strong evidence that any of these will cause more than transient deficiency; indeed, low thyroid is a known cause of poor iron absorption, so it's rather the reverse -- eat well and you still won't get good use of it. At least one gene has been identified that causes poor T4-to-T3 conversion, IOW the DNA that controls the required enzyme is defective. Anyway, if you try treating hypothyroid with diet and exercise you won't get far. I can point at myself as a good example -- I'm more active than most folks (I've done physical work my whole life) and I eat almost entirely home-cooked, nutrient-dense food, but that doesn't do a thing for my Hashimoto's.
