) and my son's last pediatric check up (he's 12) suggested he was putting weight at an unhealthy rate. Both of them enthusiastically joined me on NoS and I am grateful because it has made it easier for me to stick to NoS - at least I don't need to watch them bingeing on food when I can't. For my son, I didn't want him to become a weight-obsessed child and also, this is his growing phase, so NoS was only adapted to avoid snacks and sweets on N days - he is allowed to eat as much as he wants at the 3 meals - and he has adapted amazingly well. Instead of a huge snack when he comes from school which then delayed dinner, he either has milk and then a pretty early dinner - or as yesterday, he ate dinner immediately. He is still very amused about the whole thing and I am not sure how long he will sustain it. But I am hopeful of good habits. My husband has adapted so well that he deters me from giving in on the odd occassion when my body screams out for a snack or a sweet - and he is such a chocoholic, I am inspired by his will power. (I wonder if those with less to lose probably have even more will power because the goalpost is so closeby?). The one person who is not happy about this is my mother (and so will my mother in law protest, when she finds out). Both of them live to feed to the family and my mother made unhappy noises about a forthcoming visit - "you're on diet, what's the point, what will you eat" - but I hope when she sees I am feeling healthier this way she will understand.
How has NoS impacted your family?
Turns out I'm much more disciplined than him--even though I feel bad about it, it's nice that I'm having an easier time losing weight than him for a change! 
It's really hard to feel support from someone who doesn't understand the struggle.
