Search Results: changing a guy''s habits

So let's imagine our hypothetical guy. He finished high school and enrolled university. He is broke, which made him ugly. He's skinny because he's broke (or he's fat because of a few bad habits). He's short because his body determined it for him. And he's broke because his parents don't give him enough money even for food while the family is supposedly being low class.

BUT!!! But he is certainly not stupid.

So he decided to take a grip on his life. He's studying in university, applying for jobs (or working as an intern), spending all his salary just to live by himself and not having to starve and eating healthy a lot (fruits and vegetables and cooking meals) (or breaking his habits, which make him fat). And he's looking into fashion somewhat to see how he can make himself attractive with haircuts/hairstyles, beards (or lack thereof), clothing, jewels and so on. About being short he's not able to do anything.

And he just started it because he was trapped in high school until he became an adult.

How much time is needed in order for him to turn attractive to women if he is persistently disciplined about these changes?
