Preventing Obesity in Children, Teens, and Adults

Facts about obesity

Obesity is a long-term (chronic)
disease. It affects increasing numbers of children, teens and adults. Obesity rates
among children in the U.S. have doubled since 1980. They have tripled for teens. About
17 out of 100 children ages 2 to 19 are obese. More than 7 out of 20 adults are

Healthcare providers are seeing more of these problems in children
and teens:

  • Type 2 diabetes starting at a younger age
  • Heart and blood vessel disease
  • Obesity-related depression and social isolation

The longer a person is obese, the
more he or she is at risk for problems. Many chronic diseases are linked with obesity.
And obesity is hard to treat. Because of these reasons, prevention is very

Preventing obesity in children is
vital. This is because childhood obesity is more likely to last into adulthood. An
person has a high risk of diabetes, high blood pressure, and heart disease.


Breastfed babies are less likely to
become overweight. And the longer babies are breastfed, the less likely they are to

healthy weight. If your child was not breastfed, it does not mean that they can’t
have a
healthy weight. Talk with your child’s healthcare provider if you have concerns.

Children and teens

Young people can become obese from
poor eating habits and lack of physical activity. Genes can also affect a child’s

To help prevent obesity in children
and teens:

  • Don’t just focus on a child’s
    weight. Work to change family eating habits and activity levels over time.

  • Be a role model. Parents who
    eat healthy foods and do physical activity set an example. A child is more likely
    to do the same.

  • Encourage physical activity.
    A child should have 60 minutes of moderate physical activity most days of the
    week. More than 60 minutes of activity may help with weight loss and keeping a
    healthy weight.

  • Reduce screen time. Limit
    time in front of the TV and computer to less than 1 to 2 hours a day.

  • Encourage children to eat
    only when hungry. Tell them to eat slowly.

  • Don’t use food as a reward.
    Don’t withhold food as a punishment.

  • Keep the fridge and pantry
    stocked with healthy foods and drinks. These include fat-free or low-fat milk,
    fresh fruit, and vegetables. Don’t buy soft drinks or snacks that are high in
    sugar and fat.

  • Serve at least 5 servings of
    fruits and vegetables a day.

  • Encourage your child to drink
    water instead of drinks with added sugar. These include soft drinks, sports
    drinks, and fruit juice drinks.


Good eating habits and physical
activity can help prevent obesity. Tips for adults include:

  • Keep a food diary. Write down
    what you eat, where you eat, and how you feel before and after you eat.

  • Eat 5 to 9 servings of fruits
    and vegetables a day. A vegetable serving is 1 cup of raw vegetables or 1/2 cup of
    cooked vegetables or vegetable juice. A fruit serving is 1 piece of small to
    medium fresh fruit, 1/2 cup of canned or fresh fruit or fruit juice, or 1/4 cup of
    dried fruit.

  • Choose whole-grain foods.
    These include brown rice and whole-wheat bread. Don’t eat foods made with refined
    white sugar, flour, high-fructose corn syrup, or saturated fat.

  • Weigh and measure food. This
    is so you can learn healthy portion sizes. For example, a 3-ounce serving of meat
    is the size of a deck of cards. Don’t order supersized menu items.

  • Learn to read food nutrition
    labels and use them. Keep the number of portions you are really eating in

  • Balance your food
    “checkbook.” If you eat more calories than you burn, you will gain weight. Weigh
    yourself each week.

  • Don’t eat foods that are high
    in “energy density.” This means foods that have a lot of calories in small
    amounts. For example, a cheeseburger with fries can have as much as 1,000 calories
    and 30 or more grams of fat. Order a grilled chicken sandwich or a plain hamburger
    and a small salad with low-fat dressing instead. You can avoid hundreds of
    calories and lower your fat intake. For dessert, have a serving of fruit, yogurt,
    a small piece of angel food cake, or a piece of dark chocolate.

  • Reduce portion sizes. Using a
    smaller plate can help you do this.

  • Aim for 60 to 90 minutes or
    more of moderate to intense physical activity 3 to 4 days each week. Examples of
    moderate intensity exercise are walking a 15-minute mile, or weeding and hoeing a
    garden. Running or playing singles tennis are examples of more intense

  • Look for ways to get 10 or 15
    minutes of some type of activity during the day. Walk around the block. Walk up
    and down a few flights of stairs.
