The Best Way to Reduce Your Weight

You hear this：“Nowonder you are fat.All you ever do is eat.”You feel sad：“I skip my breakfast and supper.I run every morning and evening.Whatelse can I do?”Basically you can do nothing.Your genes，not your life habits，determine your weightand your body constantly tries to maintain it.

Albert Stunkard of the University ofPennsylvania found from experiments that，“80 percent ofthe children of two obese parents become obese，ascompared with no more than 14 percent of the offspring of two parents of normalweight.”

How can obese people become normal or even thinthrough dieting?Well，dieting can be effective，but the health costs are tremendous.Jules Hirsch，a research physician at Rockefeller University，did a study of eight fat people.They were given a liquid formulaproviding 600 calories a day1.After more than 10 weeks，thesubjects lost 45kg on average.But after leaving the hospital，they all regained.The results were surprising：by metabolic measurement，fat people who lostlarge amounts of weight seemed like they were starving.They had psychiatricproblems.They dreamed of food or breaking their diet2.They were anxious anddepressed；some were suicidal.They hid food in theirrooms.Researchers warn that it is possible that weight reduction doesn’t result in normal weight，but in an abnormalstate resembling that of starved non-obese people.

Thin people，however，suffer from the opposite：They have to make agreat effort to gain weight.Ethan Sims，of theUniversity of Vermont，got prisoners to volunteer togain weight.In four to six months，they ate as much asthey could.They succeeded in increasing their weight by 20 to 25 percent.Butmonths after the study ended，they were back to normalweight and stayed there.

This did not mean that people are completelywithout hope in controlling their weight.It means that those who tend to be fatwill have to constantly battle their genetic inheritance if they want tosignificantly lower their weight.

The findings also provide evidence for somethingscientists thought was true-each person has a comfortable weight range3.Therange might be as much as 9kg.Someone might weigh 60-69kg without too mucheffort.But going above or below the natural weight range is difficult.The bodyresists by feeling hungry or full and changing the metabolism to push theweight back to the range it seeks.
