Brown fat cells burn fat, and while fat cells store it. We have some of each kind. If we could create more brown fat cells it would help control obesity. European researchers took genetically engineered mice that expressed high levels of COX-2 and discovered they weighed 20% less than the normal mice. Both types ate the same amount, and had the same weight of bone and muscle. If they were given the popular anti-inflamatory Celebrex, they gained weight, since the medicine blocks COX-2.
PositiveTip: Maybe this is a good reason to avoid taking Celebrex. Rather than wait for a pharmacological solution in the future, start now to eat less and exercise more.
