1.Doctors say obesity,also known as severe overweight,is a complex condition.A doctor may advise medical interventions(医疗干预) in addition to changes in behavior.But experts say the more successful weightloss plans include a wellbalanced diet and exercise.
People who want to avoid 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 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 some moderate or intensive physical exercise most days of the week.This could include fast walking,sports or strength training.
Arecent study looked at four of the most popular dieting plans in the United States.Researchers at Stanford University studied more than three hundred overweight women,mostly in their thirties or 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 food plans.At the end of a year,the women on the Atkins diet had lost the most,more than four and a half kilograms on average.
Christopher Gardner led the study,reported in the Journal of the American Medical Association.He said the Atkins diet may be more successful because of its simple message to lower the intake of sugar.Also,he said the advice to increase protein in the diet leads to more satisfying meals.
But last week,another report suggested that only a small minority of people have longterm success in dieting.Researchers at the University of California found that most dieters regained their lost weight within five years.And often they gained back even more.But those who kept the weight off generally were the ones who exercised.
