Hello Elizabeth, more than age, I guess is conditions. for example, if someone is pregnant, they can't because the baby need all the nutrients the mothe has to give to it. Also if you have kidney problems, this diet is not for them. Kids in the other side, should not do this kind of diet because they are growing and they need, again, all the nutients to be healthy and strong. The problem with this diet is that people usually do it by fashion and in long terms they may find heart deseases, maybe cancer, diabetes and degeneratives deseases ... I think it is better to eat healthy, do excersises regards
