Doctors say obesity, also known as severe overweight, is a complex condition. A
4)doctor may advise medical interventions in addition to changes in behavior. But experts say the most
successful weight-loss plans include a well-balanced 5)diet and exercise. People who want to avoid 6)weight gain have to balance the number of calories they eat with the number
of calories they use. To lose weight, you can reduce the number of 7)calories you take in, or increase the number you use, or both. Experts at the National Institutes of Health say to lose
weight, a person should do an hour of moderate to intensive physical activity most days of the week. This could include fast walking, 8)short or strength training. You should also follow
a nutritious eating plan and take in 9)fewer calories than your body uses each day. A recent study looked at four of the most popular dieting plans in the United States. Researchers at
Stanford University in California studied more than three hundred overweight women, mostly in their thirties and forties. Each woman went on one of the four plans: Atkins, The Zone, Ornish or
LEARN. The women attended diet classes and received written information about the 10)foodplans. At the end of a year, the women on the Atkins diet had lost the most, more than four
and one-half kilograms on average. They also did better on tests including cholesterol levels and blood pressure.
