Any diet on which you live that contains fewer calories than you need to get through the day—like an 800-calorie-per-day diet—can be dangerous. Diets that don't allow any fat also can be bad for you. Everyone needs a certain amount of fat in their diet—up to 30 % of to?tal calories―so no one should eat a completely fat-free diet.

Don't have diets that restrict(限制)certain food groups, either. A diet that requires you to say no to bread or pasta or allows you to eat only fruit is unhealthy. You won't get the vitamins and minerals you need. And although you may lose weight, you'll probably gain it back as soon as you start eating normally again.

Some people start dieting because they think all the problems in their life are because of weight. Others have an area of their life that they can't control, like an alcoholic parent, so they focus on something they can control―their exercise and food intake.

People who diet may get lots of praise from friends and family when they start losing pounds, which makes them feel good. But eventually a person reaches a weight level and doesn't lose as much weight as before because the body is trying to keep a healthy weight, so they aren't any happier.

Some people may find it hard to control their eating, so they stick with an ex-treme diet for a little while, but then eat tons of food. Feeling guilty about the binge, they use laxatives('瀉藥).Eating too little to maintain a healthy weight or eating only to throw up the calories are both eating disorders, which are harmful to a person's health.
