Pity our poor thyroid.

This small gland is blamed for countless weight loss frustrations and is a consistent scapegoat for people who encounter fat loss plateaus.

And that’s understandable. The thyroid affects metabolism and hypothyroidism (suppressed thyroid function) can slow the basal metabolic rate and reduce fat loss if you don’t adjust your diet or get treated.

I hear from many people who have thyroid issues asking for advice on how to lose weight, how to adjust their diets, and how to improve their overall health. This isn’t a subject I’ve touched on directly, so I decided to bring on a true thyroid expert, Dr. Spencer Nadolsky, to elucidate this little gland’s function and how it relates to fitness and health.

In this interview, Dr. Nadolsky discusses …

  • What is the thyroid, what does it do, and what are hypo- and hyperthyroidism?
  • How big of an effect can impaired thyroid function have on metabolism?
  • T3, T4, and TSH hormones
  • Goitrogenic foods and whether they should be avoided
  • The role of iodine, stress, and carbs in thyroid function
  • Signs you may have a thyroid issue
  • Hypothyroidism misdiagnosis
  • And more …

In case you’re not familiar with Dr. Nadolsky, he’s a Board Certified Family Medicine Physician, author of “The Fat Loss Prescription,” and a Diplomate of the American Board of Obesity Medicine. He’s also a member of Legion Athletics’ Scientific Advisory Board and a certified “meme-ologist” on instagram. 🙂
