What can prevent Obesity in teenagers?

What kind of ruitin does a teen in america need to pick up to get a healthier lifestyle and why are there so many obest people all of a sudden?

Developing good eating habits. Some are:

Not doing fast food all the time
Cut out the junk food between meals
Keep them active to prevent boredom eating
Keep them active to boost metabolism
Buy better choices of food when shopping
Don't make them clean their plates if they are not hungry
Monitor and police the TV, computer and video game time

It's tough these days because kids cannot just go out and play like we could. There are too many child predators waiting for the opportunity now. But get creative. Source(s): My daughter was starting to get heavy this past summer and by doing these things, she is now back to her ideal weight. We realized after speaking to her Pediatrician that we were making some mistakes.

NOT closing parks and sports fields in the UK would be a start!

Then banning Console games!
It's not 'all of a sudden'. It's been the case for ages.
What prevents obesity is balanced diet and lots of physical activity.
Healthy eating and exercise
better eating habits as a child. you have to teach your children to eat well while they are young because those habits will stay with them.
get the teens off the damned video games and cell phones...they need to be out playing REAL games....getting exercise...instead of being "couch potatoes"
