Whats the cause of Childhood obesity?

I believe the sole cause is Computer games!! Not many get out and play football etc they'd rather play Xbox or Playstation

Yes i agree,when i was a girl my mum couldn`t keep me in,i`d always be out playing,skipping etc and the boys would always be playing footie and stuff.todays kids are just been left to sit there backsides down in front of tv and computers for hours on end and eating junk instead of being out and about getting exercise.

while watching tv (no excersize) eating junk food eg chockolate and crisps!!
The way there bought up and yeah your right, not enough getting out and playin sports.
blame the parents for allowing them to sit in front of the tv etc... blame the parents for the diet they eat and blame the parents for being totally ignorant of the fact the child will become ill.... killing them with "kindness and love" wont help when they are in hospital.....
kids these days hardly go out and have fun, even in their own gardens. they all sit at home, do no excercise and eat constantly. and the food consumed isn't even healthy. TV and the lack of excercise is making all the children really unhealthy and fatter.

they need to get out more and less time indoors sitting watching telly.
i dont know but ill tell you what does NOT cause childhood obesity, videogames
Many things indeed. eating lots of candies is the biggest of them. children shouldnt eat that so much candies. now most of the people feed their children with candies and forget the main healthy food... also watching t.v excessvily is on of the reasons. it makes the person so lazy and listless and unwilling to do any job. and off-course children needs to run alot and make efforts to burn the food they eat......
