My son has just turned 13 and have recently noticed how he has got larger. First I noticed he had man boobs which more recently have got bigger and quite concerning then I realized how big his belly was and then how big his thighs were. I also realized his double chin which has got larger and more noticeable. We went shopping the other weekend and we where in the children's section no trousers would fit and we had to go into the men's section and pick up a 34 inch pair he also needed a medium t-shirt. He is aware of his size but he doesn't seem overly concerned. I asked him how much he weighs and he said last time he weighed himself he was 57kg which really scared me but he then said that was a couple of months ago. So I decided to weigh him myself and he was 67kg. We have started to lower portion sizes ban crisps fizzy drinks sweets and chocolates but in having done this for 3 weeks he has only got heavier and know weighs 70kg. I have sat him down and asked him about what he eats and he said nothing but what he gets from home and said he has been quite self conscious and he is perticuarly conscious about his man boobs. Anybody going through a similar situation with any advice or support would be great. He does PE lessons Jujitsu once a week and goes running once/twice a week too and has been doing this for 2 years now. My husband is reluctant to take him to the doctors because he can't really see a difference in him and didn't want to make him feel any worse about himself and would rarther make smaller changes on our own. Thanks for any advice you can give or any similar situations.
