Can energy balance help reduce obesity?

If the problem is that too many people are in positive energy balance, then the solution must involve changing a combination of energy intake and energy expenditure to achieve balance. Efforts to develop effective strategies to reduce obesity rates could benefit from an understanding of how energy balance is achieved by the body.
