My 13yr old son is constantly saying he's fat and tubby. He is a good weight for his age/height and is physically active everyday. I have been attending slimming world for the past year and have been explaining to him that it isn't a diet, but a healthy lifestyle choice and he understands that and I try to involve him in picking what meals we have and swap sweets for fruit when we have family movie night. I am struggling with his constant body shaming of himself, thought it was just a faze but it is every single day and has been for several months. Should I be worrying more? Any tips to help or should I be taking him to the GP for reassurance? Thanks
