Check how much fat you've got down there, if you've got a whole lot, then you may 'gain' an inch.
First know you don't gain anything. For example, lets say you were always seven inches. With fat (lets say 30lbs) you would have six inches as the fat pouch in your pubic area would cover an inch up.
So when you lose weight your penis doesn't grow - no gains - instead you reveal the hidden inch.
However losing weight purely for your penis isn't generally a good thing. But if it motivates you enough to do it, then do it.
You'll also notice that in losing weight, you'll have better health and probably have the ability to last longer.
