Can you believe approximately 17 percent of American children ages 2 to 19 years are obese? How about this fact: approximately 60 percent of overweight children ages 5 to 10 already have at least one risk factor for heart disease? We are all to blame for this - parents, schools, kids - all of us.

Our pets rely on us entirely for their nutrition. So if you're making your own judgments, that could lead to a mistake.

I have encouraged my kids to eat well from day one. I add flavor - herbs and spices - to everything because I don't want them getting used to starchy, bland food.

It's not weird to look at yourself in the mirror at the gym - that's why they're there! You have to make sure that you're doing things right.
