Its hard to say. I saw a young girl (6) at the Zoo the other day and her parents were skinny and she was chubby and eating a packet of twisties. All I could think was, it looks bad when you see a chubby kid eating junk food. And I get that she is young and she will probably grow up to be fine, but trust me, as someone who has been overweight, you dont want to be an overweight child. School is hell for a kid who is chubby.
