Get 20% off at timeline.com/vanessa In this episode, I'm joined by Dr. Catherine Clinton to explore how circadian biology, light exposure, and cellular electrical charge regulate metabolism, hormones, and fat loss — often beyond calories alone. We discuss how morning light impacts leptin signaling, insulin sensitivity, cortisol, and melatonin, why modern indoor living disrupts metabolic health, and how maintaining a strong negative cellular charge is critical for mitochondrial function. We also cover red and infrared light therapy, optimal timing, metabolic benefits, and key considerations during pregnancy — plus how to integrate protein intake, calories in vs. calories out, and resistance training with circadian alignment for sustainable fat loss. Topics include: Light exposure and leptin signaling Circadian rhythm and fat loss Cellular charge and mitochondrial health Grounding and infrared light Red light therapy timing and pregnancy considerations Balancing calories, protein, and training with circadian biology 🔗 Dr. Catherine Clinton's book Optimize: drcatherineclinton.com/optimize Get 20% off the Tone Device to try on a PSMF Day!
