Eps 448: Gaining Weight Despite Diet and Exercise? Your Thyroid May Be the Missing Piece with Dr. Amie Hornaman
Have you been eating well, exercising consistently, and still gaining weight, only to be told that your thyroid labs are “normal”?
For many women in their 40s and 50s, stubborn weight, exhaustion, brain fog, constipation, thinning hair, low mood, and feeling unusually cold are quickly blamed on perimenopause or aging. But because these symptoms can overlap with thyroid dysfunction, it may be worth asking what was actually evaluated.
In this episode, I sit down with Dr. Amie Hornaman, also known as The Thyroid-Fixer, to explore the connection between thyroid health, metabolism, and perimenopause.
Dr. Amie breaks down the language of thyroid health, including TSH, free T4, free T3, reverse T3, T2, and thyroid antibodies. She also shares why she believes symptoms and medical history should be considered alongside laboratory results.
We also discuss why women should not automatically respond to unexplained weight gain by eating less or exercising harder, which thyroid questions they can bring to their healthcare provider, and why sleep, nutrition, stress, gut health, and foundational habits still matter.
