Your TSH is not very high, slightly borderline high. In keto diet
, one should not make wrong food choices, as it allows high fat food. If you take processed fat foods or high processed non-veg foods it may impact hormones. When you are off- keto stay away from processed foods, have very low rice and wheat based foods and have high natural foods including good carbs in the form of fruits, starchy veggies and legumes.
