Our country's first lady wants to improve diet and exercise routines to combat childhood obesity, a medical term that describes being dangerously overweight. "Our children are on track to be less healthy than we are," Michelle Obama said last week as she pushed a crusade involving doctors, food and beverage makers, government and even the entertainment industry.
Thirty-two percent of U.S. children -- about one of every three -- are considered obese or overweight. That's the highest percentage of any developed nation.

After discussing the issue since last year, the president's wife now is working to change how millions of youngsters eat, exercise, look and feel. Her "Let's Move" drive has four main parts: (1) Helping parents learn more about nutrition and exercise, (2) improving the quality of food in schools, (3) making healthy foods more affordable and accessible for families, and (4) focusing more on physical education.
Steps have begun. Major suppliers of foods to school cafeterias pledge to cut sugar, salt and fat and increase whole grains and produce clear. The front of beverage cans, bottles and vending machines will have clear calories labels by 2012. Film studios, TV networks and other media companies will show public service announcements by athletes and others urging kids to trade video games for physical activity at least some of the time.

As she describes in the video below, Mrs. Obama takes steps to help daughters Malia and Sasha stay fit: No weekday TV. Smaller meal portions. Low-fat milk. Water bottles in lunch boxes. Grapes on the breakfast table. Apple slices at lunch. Colorful vegetables on the dinner table. "We have everything we need right now to help our kids lead healthy lives," she advises parents. "It was really very minor stuff, but these small changes resulted in some really significant improvements."
