I haven't been following the story but I'm not sure it is fair that the boy is taken into care as the mother could argue that he is only happy when he gets junk food and anything else would make him unhappy.

But I guess she does have a responsibility to feed him right... but its parents that are ultimately responsible for the welfare of their children.

Something about obesity to consider is that in prehistoric times food was scarce so humans have evolved to want to eat whenever they can. Now in the modern world, where food is everywhere, a lot of people can't stop eating.

So it is a genetic thing.
