Summary
There are three kinds of fat in the body: white, brown and beige. While excess white fat results in obesity, brown fat is associated with leanness and lowers blood glucose levels. Recent animal experiments show that under certain conditions, white fat can be transformed into beige fat, leading to benefits such as weight loss. The current project grant involves examination of human fat cells grown in the laboratory and investigation on the genetics of brown and beige fat.
Obesity ensues when calorie intake exceeds energy expended. Hitherto, up-regulating energy expenditure is a relatively unexplored avenue. This project will address 3 facets of energy expenditure (fat, muscle and neural control). Understanding how sex and steroids act in concert to regulate energy expenditure will pave the way towards developing novel anti-obesity agents. This work will delineate mechanisms that underpin gender differences in the regulation of body weight.

Summary
Obesity is a major health crisis, but effective treatments remain elusive. Body weight is determined by a balance of food intake and energy expenditure. Understanding both sides of this equation is essential to combating obesity. This project will show that the rate at which muscle uses energy is an important determinant of energy balance and contributes to the propensity to become obese. The work will define muscle as a target for developing anti-obesity therapies.
