“Researchers at Yale School of Medicine have found the brain's appetite center uses fat for fuel by involving oxygen free radicals-molecules associated with aging and neurodegeneration. The findings, reported in the journal Nature, suggest that antioxidants could play a role in weight control. The study's lead authors were Sabrina Diano and Tamas Horvath, who are an associate professor and professor, respectively, in the Departments of Obstetrics, Gynecology & Reproductive Sciences and Neurobiology. Horvath is also chair of the Section of Comparative Medicine. ‘In contrast to the accepted view, the brain does use fat as fuel,’ said Horvath. ‘Our study shows that the minute-by-minute control of appetite is regulated by free radicals, implying that if you interfere with free radicals, you may affect eating and satiety.’ The results also imply, added Horvath, "that each time a feeling of fullness or satiety is reached during a meal, you may be chipping away some time from your maximum lifespan as the most free radicals are produced when satiety-promoting brain cells are active."
