I Ate 1,000 Sardines and Became Cold Resistant

Walking shirtless at 0°C didn’t feel uncomfortable anymore. That experience led me down a scientific rabbit hole, where I learned that certain omega-3–derived signaling molecules, like 12-HEPE, can increase thermogenesis, activate brown fat, boost heat production, and improve muscle metabolism. This isn’t just a quirky diet story—it’s a real intersection of emerging metabolic science and lived experience. #Omega3 #BrownFat #Thermogenesis #MetabolicHealth #ColdExposure #Sardines #NutritionScience #FatMetabolism #EnergyExpenditure #StayCurious
