Tips To Get Or Stay Slim

Emily Senay: They're Basic But Critical And The Younger, The Better

(CBS)  Being overweight can be dangerous for young and old alike. And it's hardly just a matter of vanity.

The Early Show medical correspondent Dr. Emily Senay notes that obesity increases the risk of developing a long list of health problems, including serious chronic diseases such as heart disease and diabetes.

In many cases, excess weight is accompanied by other risk factors, such as high blood pressure, high triglycerides, high levels of bad "LDL" cholesterol, glucose intolerance and elevated insulin levels.

"All these things," Senay tells co-anchor Julie Chen, "factor into the No. 1 killer of Americans, cardiovascular disease. And cancer."

In general, she says, these can all add up to big trouble if they're not recognized and controlled.

"One of the scariest parts of this epidemic," Senay says, "is the children. Obesity has doubled in children in the past 20 years and the question is, 'What's going to happen to these kids?' Are we going to see an actual decline in the longevity of the American population because they're getting obese at such young ages? And are they going to accrue end-stage problems at younger ages? It's a huge question mark."

Senay says there are some proven strategies that can help shed the pounds and prevent weight gain. Lifestyle changes such as healthier food choices, smaller portion sizes and regular physical activity are the best way to fight obesity.

In severe cases, there are also medications that can help, as well as surgery to reduce the size of the stomach and prevent calorie intake.

The key to preventing obesity is to start early in life with a healthy lifestyle.

Research shows that with the right tools children and their families can learn to enjoy healthy foods and be selective about food choices, and kids can develop habits that could stay with them throughout life.

Encouraging a routine that limits TV and video games, and emphasizes regular physical activity is also important.

Even simple activities such as taking the stairs, riding a bike and playing outdoors can be a big help.

Fitness and nutrition programs in schools are useful in reinforcing these lessons.

Parents and other adults need to take responsibility for ensuring that children have access to healthy foods and drinks — at home and in school — so healthy choices are available.
