Biohacking with Brittany

Sarah Kennedy, CEO of Calocurb, joins me to explore the science of appetite regulation, hormone health, and why bitter plant compounds may be the key to modern weight challenges. We unpack the fascinating 15-year research journey that began with a $30M government grant in New Zealand and led to the discovery of a specific hop variety that increases satiety hormones by 600%. Sarah contrasts Calocurb with drugs like Ozempic, sharing why a natural, hormone-supportive approach could be the future of weight management. From PMS cravings to perimenopause, from post-Ozempic rebound hunger to late-night snacking, Sarah explains how Calocurb works with your body rather than against it. WE TALK ABOUT:  14:00 – The surprising science of bitter taste receptors in your gut 19:00 – How Calocurb compares to Ozempic and Wegovy 26:25 – Hormonal influences on hunger (menstrual cycle, perimenopause, menopause) 28:30 – Why 70% of people are overweight in today’s food environment 34:50 – Safety guidelines for women, pregnancy, and breastfeeding 39:00 – How to time Calocurb for cravings, late-night snacking, and travel 44:30 – Why women in their luteal phase may benefit most 47:30 – Addressing childhood obesity and adolescent use of Calocurb SPONSORS: Join me in Costa Rica for Optimize Her, a 5-night luxury women’s retreat in Costa Rica with yoga, healing rituals, and biohacking workshops—only 12 spots available.
