I didn't see anyone run any numbers for you anywhere so I thought I'd throw them up so you could see how much exercise and diet 17lbs is.

At 3,500 calories per pound, 17 pounds is 59,500 calories.

Burning 59,500 calories in 5 days requires an average of 11,900 net calories burned over what is consumed.

Consider then, what you eat has to be added to that total. 1500 calories per day taken in works out to 13,400 calories burned per day to reach this goal.

If you have a very, very high BMR you may be burning 3500 calories per day.

According to the calculator and Runner's World a 315 lb. person would burn 6253 calories over the course of a marathon.

So, if you add a (very high) BMR to a daily marathon that works out to ~9,750 per day, leaving you an additional half a marathon or so to make up the rest of the calories to reach your 13,400 per day burn goal.

Not that you couldn't figure that all out on your own, I just like running numbers and figured I'd share what I came up with.
