Summary
Dr. Nadia Pateguana discusses the benefits and potential side effects of intermittent fasting, addressing the ongoing debate about fasting's effects on thyroid function, cortisol, and adrenaline. She explores who should and shouldn't practice intermittent fasting, the differences between various fasting protocols, and how hormonal responses differ between men and women. The conversation covers whether the metabolic benefits of fasting outweigh potential downsides for different populations.
Key Points
- Intermittent fasting can improve insulin sensitivity, reduce inflammation, and promote autophagy
- Potential side effects include elevated cortisol and adrenaline, especially in women and those with thyroid issues
- Women may need modified fasting protocols that are less restrictive than what works for men
- Thyroid function should be monitored when adopting extended fasting protocols
- The benefits of fasting largely depend on metabolic health status and individual hormonal balance
- Starting with a 12-14 hour overnight fast is safer than jumping into longer protocols
- Fasting is not appropriate for pregnant or breastfeeding women, or those with eating disorder history
