Those little fruit flies floating around the ripening cantaloupes pack some fat between their tiny wings. They’re cold-blooded and burn their fat to warm up. “They have really beautiful fat, the flies ...
Three decades ago, in a lab at The Rockefeller University, New York City, Jeffrey Friedman, MD, PhD, observed a paradox that would forever change our understanding of obesity. His subjects, a rare ...
Most obese patients grow resistant to satiety signals from the hormone leptin. A new study shows that leptin sensitivity can be restored in mice, leading to weight loss. Worldwide obesity rates have ...
