Eat less, exercise more. It sounds like a simple enough solution to prevent childhood obesity, but perhaps it is too simple. Some research suggests that we have such an obesity problem in the United States because we live in an obesogenic environment--one that encourages us to eat too much and exercise too little.
A key step in taking an overall ecological approach to obesity prevention is to assess what environmental factors are contributing to the problem. Environmental causes require environmental solutions. An environmental intervention modifies the environment to make healthy eating and active living choices easier to make. Put another way, an environmental approach makes healthy choices easier for whole communities.
