Lots of people are unhappy with their present weight, but most aren't sure how to change it. You may want to look like the models or actors in magazines and on TV, but those goals might not be healthy or realistic (现实的) for you. Being healthy is really about being at a weight that is right for you. The best way to find out if you are at a healthy weight or if you need to lose or gain weight is to talk to a doctor or dietitian（营养学家）. If it turns out that you can benefit from weight loss, then you can follow a few of the simple suggestions listed below to get started.
_______________________. Ask your mom or dad to lend help and support and to make lifestyle changes that will benefit the whole family, if possible. Those who have the support of their families tend to have better results with their weight-management programs.
Watch your drinks. It’s amazing how many extra calories can be in the sodas, juices and other drinks that you take in every day. Simply cutting out a can of soda or one sports drink can save you 150 calories or more each day. Slake yourself with water or other sugar-free drinks when you’re thirsty and stay away from sugary juices and sodas.
Stop eating when you’re full. Lots of people eat when they’re full. Try to pay attention as you eat and stop when you are full.
Avoid diet pills. They can be dangerous to your health; besides, there’s no evidence that they help keep weight off over the long term.
