Nothing works but analyze: is thyroid issue preventing weight loss? Map thyroid symptoms: fatigue, cold sensitivity, hair loss, difficulty losing weight despite diet. Calculate: if subclinical hypothyroidism is present, what's needed? Show me the thyroid optimization: testing needed, treatment options, dietary support. Give me the thyroid protocol: get these tests, if results show this, do this. Include: whether thyroid is the missing piece, what tests to demand, and if diet alone can't fix this.
