For most of us, dieting is anannoying fact life. With so much information available, it can be difficult totell which weight-loss strategies really work. Let’s start by taking a look atsome confusing myths (荒谬)。

1.All calories are created equal.

What you eat, not how much, isthe main factor behind weight gain. In fact, the body burns many more caloriesdigesting carbohydrates than it does digesting fat ,For every 100 calories ofcarbohydrates we consume in excess (超过)of our daily requirement ,only 75 are turnedinto body fat .But 97 of every 100 excess fat calories are turned into body fat.

2.Desserts and fast foods are forbidden.

Some experts advise againstdescribing foods as “ good ”and “bad ”.Even cakes ,pies ,and ice cream can beworked into a diet, Moderation is the key. Besides ,a plain hamburger on a bunis still a healthful choice ,So is baked chicken or a green salad with low–cal,dressing. But watch out for French fries, and fried chicken of fish .

3.It makes no difference whether you’re topor bottom –heavy.

In fact ,where weight isdistributed makes all the difference. Recent studies suggest that people whostore fat on the upper body (apple shape )rather than on hips and thighs (大腿)脚（pear shape ）may have an increased rick ofheart disease.There is probably little you can do to change how your body isgenetically programmed to store fat ,But you can lost excess weight overall .

4.Fasting is the fastest diet .

Some studies suggest thatsuddenly reducing calorie intake puts the body into “starvation mode ”,whichcauses it to conserve calories and decreases the rate of digestion .The moreoften you deprive yourself of food ,the better your body may get at storingcalories ,So ,in the long run ,repeated fasting may actually weaken your weight–loss efforts.

5.To keep weight off ,simply watch what youeat

According to studies ,exercisecombined with dieting ensures weight loss better than dieting alone does.Experts also agree that having regular, moderate exercise is more importantthan occasional exercises. Researchers encourage patients to take the stairsinstead of the elevator and park the car far from where you are going andwalking.

6.It’s all your fault that you’re fat

Research at the University of Pennsylvania, School of Medicine indicates that body shape and size are in largepart decided by a person’s genes. In short ,some people are naturally morelikely to be fat than other.Moreover, someone who was fat in childhood willhave more fat cells than a person of average weight. Once made, the cells mayenlarge or shrink (缩小),but they never disappear.

Yet genes don’t have to controlyour shape ,The size of your fat cells depends on you ---- on your eating habitsand lifestyle ,Most important ,before getting caught up in dietary myths ,letgood sense shape your eating habits ,Your body will thank you for it .
