Exercise physiologist Bob Greene, Oprah's fitness trainer, had a few things to say about combating childhood obesity while in Toronto last week. He believes parents can make a significant difference. Here are few of his insights from over a dozen questions posed:

• Where do we start - with eating habits or exercise? Bob strongly feels activity is the bigger problem. Most studies reveal we're eating 2 or 3 percent more, but moving 16 percent less.
• How can parents get their kids to eat well and be active? Bob simply says parents need to emulate the healthy behaviors themselves.
• How do you get kids off the computer and outside? Bob recommends parents plan active family time. Don't just send kids outside to play, plan active weekends, take a walk and play catch with them yourself.
• Does Oprah's yo-yo weight set a bad example for kids? Bob stated that 93 percent of anyone who has lost 50 lbs gains it back within five years. Bob can recall Oprah only gaining 20 pounds two different times in the last 12 years.

Bob Greene's common sense insights will produce more than just healthy kids -- his suggestions positively impact the entire family unit. Whether your children are infants or college students, kids pay attention to their parents' food and exercise behaviors. Actions truly speak louder than words when it comes to influencing your kids to make healthier choices. Studies cite we are moving 16 percent less -- pretty revealing statistic to me.
