How much weight can you lose by starving for two months?

I don't know your situation, but I do know - and I'm pretty sure you know, that starving yourself is not the best way to lose weight. You need to do some exercise every day, drink heaps of water, and eat healthy food. There are a multitude of good diets out there you can try without resorting to starving yourself. Starving will leave you weak, dehydrated, and maybe even make your stomach lining get eaten away in the process. Don't do it! In two months, you would be dead.
