Kayla Barnes: The Science of Female Biohacking - Gut Health, Toxins & Menstrual Cycles | TUH #149

About this video

Brecka interviews Kayla Barnes on female-specific biohacking, covering gut health, environmental toxins, menstrual cycles and menopause. Barnes argues protocols designed for men harmed her thyroid and hormones, stresses sleep, light exposure and foundational habits for women, and discusses, in her view, why delaying menopause onset could matter for female longevity.

Key takeaways

• Barnes states male-oriented biohacking protocols coincided with declines in her thyroid and hormone health
• She argues women’s health needs cycle-aware, sex-specific approaches rather than copied male protocols
• Barnes presents sleep timing, evening light reduction and meal timing as core parts of her routine
• Brecka and Barnes discuss menopause timing as, in their view, a major female longevity lever
