Could you expand on this a bit? It may have some reason to do with why she is compensating with food.

18 is way too young to be fat and lazy. Does the kid have a job? Tough nut to tackle head on with a conversation, but it sounds your heart is in the right place.

Man. This is a tought one.

Perhaps you could go on a diet together. Show that bussa how to take carbs out of her diet. Show her how to exercise.

Show her some pictures of  what Covers degenerates look like and she'll be in the gym on Monday. OR, she'll join the forum and have something to do all day.

You'd better hire a carpenter to reinforce the floor boards of your house.

Some pizza is okay, but I completely agree with the rest of your assessment.  Only problem is that most humans like myself are too lazy to get at least half an hour a day of exercise. 

Also, as you get older, it is much tougher to stay motivated and exercise, since most people recite the bullshit line that they are too busy to join you for a work out. 

Since your niece is living with you, stock the fridge and pantries with healthy foods and don't push her, but casually encourage her to join you during work outs.  If she politely declines, do not ask her again.   

First lead by example by eating fairly healthy and working out yourself on a consistent basis.  After a few months, if she is still a useless slob, have a long talk with her whether she likes it or not.

If she does not heed your recommendations, be a man and tell her to find somewhere else to live because she disgusts you with her unhealthy ways.  You may hurt her feelings and she may bawl like a spoiled baby, but she will likely respect you down the road for caring about her.
