I think you're thinking too much about numbers! Just eat good, do your exercise, basketball or whatever. But think, that 832 or whatever it was is probably a figure for top level players. I don't see scientists hooking up there machines and equipment to kids in the school gym, or guys meeting up in the park for a casual throw about. So I think you should use a figure of more like 600cals an hour. But as I said, forget all that, eat good stuff, get some exercise done and see what happens. If you're wanting a time frame, it will never happen!
good point. thanks for the input.
