I actually want to avoid putting on more muscle because they are actually already pretty muscular, maybe this picture is a bit better link , I'm sorry if I disgust you with this picture I know it looks repulsive :/
carbs, proteins? I mean there is no way to go about getting more weight in the arms without putting on weight in general, but to get it to focus on the arms and shoulders you would have to do workouts specific to those areas. So lat and trap pulldowns, bicep and tricep curls. If you do low weights with high reps you won't bulk up but you may get more tone... Otherwise aside from running less I don't know how you would put weight (presumably) fat in those specific body parts
1000? a day? That's a lot! That will be hard to do.
depends on what you eat...a couple of donuts add up trust me lol
