What if your low energy, stubborn weight gain, brain fog, poor recovery, mood changes, and stalled progress aren't simply signs that you need to work harder—but clues that your thyroid isn't functioning optimally? Dr. Amie Hornaman, author of The Thyroid Fix, joins us to explain why she considers the thyroid the body's "master gland" and why standard thyroid testing may not tell the entire story. They break down TSH, free T3, free T4, reverse T3 and thyroid antibodies; the difference between "normal" and optimal lab results; Hashimoto's and hypothyroidism; and when thyroid hormone replacement may be appropriate. Amie also explains how gluten, over-exercising, chronic under-eating, nutrient deficiencies and aggressive GLP-1 use may affect thyroid health and metabolism. Plus, she explains the importance of iodine, selenium, magnesium, protein and dietary fat, detoxification, and so much more!
