Leptin
Leptin doesn't help obese people because the brain doesn't know the leptin is there. "Giving leptin only helps in a few extremely rare cases in the world in which people make no leptin at all, which causes them to overeat and become obese. When those people received leptin by injection, they stopped overeating and lost weight. But for the vast majority of people, the treatment won't work, nor is leptin approved as a medical treatment for weight loss." WebMD.
