Your metabolism isn't broken. It's just confused by mixed signals from your thyroid and growth hormone.
Andrew Huberman talks a lot about optimizing hormones, but here's what he gets right about thyroid function that most doctors completely skip over. Your thyroid doesn't just control your energy levels - it's running about 70% of your metabolic show. And when it's not working properly, no amount of intermittent fasting or cold plunges will fix your sluggish metabolism.
What you'll discover: • Why your thyroid controls 60-70% of your resting metabolic rate and what that actually means for weight management • How growth hormone peaks during your first 3-4 hours of sleep and why this timing matters more than total sleep hours • The real science behind cold exposure increasing thyroid production by 15-20% (and why it's not just hype) • How chronic stress tanks thyroid function by up to 30% through cortisol interference
Nina breaks down the actual research on thyroid optimization without the wellness industry nonsense. You'll learn which strategies have real science behind them and which ones are just expensive placebos.
