Do you have Hashimoto's hypothyroidism? If so, because this is an auto-immune disorder, caused by inflammation in the body, you may need to reduce your SATURATED fat intake (think fat from 4-legged critters here - beef, pork, ham, butter, cheese). Saturated fat can cause inflammation, which causes more damage to your thyroid. I have Hashimoto's, and I have limited my saturated fat intake, and have seem dramatic results. I agree with PPs about finding other sources of lean proteins to help you minimize your fat intake, and would add that a focus on healthy fats will be helpful to you.
