I don't think the plan has to be too restrictive. But remember that it is sugar that you need to avoid. There is always junk food around my house but my kids eat very little of it. I have tossed so much junk ( chips, candy etc ) that I don't get why it is even in the house. We still have junk from the holidays.But again, I am not looking at the weight issue. I am considering the ADHD issue. Take away the poison for as long as your child can stand. Then give him a sugary treat and see if there is a difference...I would guess that there will be a difference and if your child is lucky, he will even get sick when / if sweets are reinstated.
