You pretty much can't turn on the tv with out hearing how fat American kids are today. Every empire must fall. In Rome, Christian was the downfall. In England it was overextension. Apparently the fall of the American Empire will be juvenile diabetes.
A new book tackles the “epidemic” of childhood obesity in our country: Ending the Food Fight by Dr. David Ludwig, who founded the Optimal Weight for Life program (OWL) at the Children's Hospital Boston. Dr. Ludwig claims success for his method comes from a low-glycemic diet.
Now, I was once a fat kid, and actually would like to have been one now when being fat doesn't seem to put you in the minority. That said, I really watch it with my kids. Not psycho “baby anorexic”, just a concern for establishing good eating habits early on. My parents let me eat whatever I wanted and convinced me the resulting fatness was genetics and nothing I could combat. I don't know about special gylcemic diets, but I do know that modeling good eating habits for your kids does more for putting them on a solid health (physical and mental) foundation than anything.
