Hi Little John’s Mom
The most probable reason for the difference is genetics. Building upper body strength through resistance training will certainly help. At this young age weight training is not recommended, but training with his own body weight is. I would strongly recommend that you make and appointment with a biokineticist and let them devise a program for him. In terms of the food make sure that he eats 5-6 meals per day. Always combine a low fat protein with a low GI Carb and add at least 5 servings of fruit and vegetables per day. View some of the archive material of this web for ideas.
