Physical Exercise Against Obesity

Obesity results from an energy imbalance: too many calories absorbed, too few calories burned. A number of factors influence the number of calories (or "energy") people burn each day, including age, body size and genes. But the most variable factor - and the most easily modifiable - is the amount of activity that people do every day.

Staying active can help people maintain a healthy weight or lose weight. It can also reduce the risk of heart disease, diabetes, stroke, high blood pressure, osteoporosis and certain cancers, as well as reduce stress and boost mood. Inactive (sedentary) lifestyles do just the opposite.

Despite all the health benefits of physical activity, people around the world do less at work, at home, and when moving from place to place. Globally, about one in three people engage in little or no physical activity. (1) Levels of physical activity decrease not only in wealthy countries, such as the United States, but also in low- and middle-income countries, such as China. And it's clear that this drop in physical activity is a key contributor to the global obesity epidemic, and in turn, to rising rates of chronic disease everywhere.
