The Feminine Longevity Shift: Why Women Age Faster When They’re Out of Alignment
Biohacking with Brittany
In this free live masterclass, I connect the dots between women’s healthspan, chronic stress, and the biological cost of living out of alignment. Even when your habits look “healthy.” I talk about why the longevity conversation has been dominated by male-centered frameworks, and what happens when women override their intuition for years (in work, relationships, family dynamics, and daily decisions). This is an invitation to stop treating intuition like a “soft” topic—and start seeing it as a health input that shapes inflammation, hormones, nervous system regulation, and...

Biohacking with Brittany
Modern motherhood can make “detox” feel like the answer—especially when you’re exhausted and convinced you just need the right protocol to get your body back. Eva Hooft unpacks why the do-more, cleanse-harder mindset can keep women stuck, and how real healing starts with safety, not force.
