I think it would be great if parents cut out refined flour and sugar products from their children's lives. I don't think it would be a good idea to go super low carb, though. kids have more energy, and need more food to continue growing healthily. Cutting out the snacks and cr*p and fast food that children eat, becuase their parents allow it, would be a big help in this countries obesity problem.

As for studies, i'm sure there are probably tons of studies on childhood obesity. It only takes common sense to realize that cutting out refined sugar and flour and trans fat filled snacks would help. Less kids would go through the pain of being overweight if they were fed a whole food diet (definitely including healthy higher carb items, such as whole grains) that didn't include sugary snacks and fatty fast food meals.
