ADVICE FOR PARENTS: DO MORE, TALK LESS

Experts offer these guidelines for parents who want to help their teenagers achieve or stay at a healthy weight.

Don't nag. Don't be a food cop. Adolescents and teenagers are at a point in their development where they want independence and autonomy, so nagging probably won't work.

Lead by example. Studies show that parents and families can be extremely influential on adolescents, even though it might not seem like it at the time. If you eat right and exercise regularly, eventually they will, too.

Do it for the whole family. Create a healthy food environment in the home and don't single out an overweight child for special food or activities.

Make it easy. Keep sliced fruit in the refrigerator. Make your own low-fat pizzas.

Give them a say. If you want to reduce the amount of junk food and treats in the house, ask the kids to participate in deciding what to eliminate.

Eat together. Research has shown that regular family meals have a positive effect, especially for girls.

Cut down on screen time. Limit the time kids spend online or watching movies. Take TVs out of their bedrooms.
