>Im a fat girl and can only eat

If you're still fat in your 20 you're fucked. In general, it's way harder for you to lose weight now and keep that weight. Like think about some smoker who smokes 2 packs a day, that's how much you fucked up your body, but the smoker can quit, and his body will detoxify. With fat, that doesn't really happen.
