My son, who is 11 and ADHD.. the distractable kind, not the tunnel version as myself
I thought he was alittle heavy, so did his doctor. He weighed 135 but is 5'2" and is big boned (Trust me, I remember his birth 12lbs 13oz!)
Recently I calculated his ideal range for body fat using Protein Power and they went like this 125-137.
Since my son's been on his version of Atkins diet (he eats what he want for lunch at school) he's lost 4 lbs. The good news its not muscle its fat. But he isn't losing it fast. It took 4 months for this to happen. My daughter cheats (She buys candy without telling me.. I find out though) She is 14. She has lost 3lbs but has more body fat, her range of weight should be 100- 116 (She is also 5'2" but is medium boned) She currently weighs 132. She is also ADHD with OCD too. My impulsive one.

What I want to stress is that the low carbing doesn't take muscle from the child and it doesn't have to make the person lose weight. I lost 45 lbs so far but then I weigh 280 now! (I used to be 325)

Something else. My kids are calmer and more, what's the work, um... more relaxed in listening to parenting.. does that make sense? They co-operate more and they wind down faster.
In the last 3 months, I've been able to get them to do chores - and no I don't bribe with food
The only thing I'm alittle concerned with is the fact my teenage daughter is developing a zit covered face... I was always told fat is the cause but I've also heard cleaning daily will help.. I'm working on that
