Hypothalamic Switch Determines Appetite, Influences Obesity Risk
As a medical school professor, this is one of the most eye-opening findings I've seen in metabolic research. UT Southwestern researchers discovered a molecular "switch" in the hypothalamus that decides whether brain cells become appetite-suppressing or appetite-stimulating. The transcription factor Otp directs... https://www.utsouthwestern.edu/newsroom/articles/year-2026/feb-developmental-switch-brain-obesity-risk.html MetabolicHealth #Obesity #BrainScience #Longevity #HealthLongevitySecrets
