So actually, what quantity of energy you put into your body is literally the only provable way of changing your mass..... (what about if you increase/decrease your basal metabolic rate?)
So it's NOT actually a stupid argument.
It's the only scientifically supported one.

Too funny! (not to mention somewhat simplistic). It seems obvious that the human body is neither simple nor a machine... this is probably why your subsequent statements are so out of whack.
The thing is, if things are as simple as you seem to think they are, we would not need endocrinologists or microbiologists, we could just solve all of our problems with high school physics. I watched an interesting documentary that left me somewhat impressed with the complexity of the metabolic processes that we all have going on: you may not agree with the professor here, but it would be hard for anyone to watch this and conclude that we are inhabiting 'simple machines'.
