Increased Metabolism

Question
Hi, Im 18 years old and over the past two years have lost about 50 pounds.  I recently joined my college swim team, where we typically swim 5-6000 yards a day plus weight training, 6 days a week (double sessions 2x a week).  I understand that for every 1000 yds swam, someone my size, should consume, approx., an extra 200 calories.  The dramatic increase in caloric need is a concern to me.  
I understand on these days, my body may need over 4000 calorie.  On Sundays, the day off, I feel like I am needing more than the normal 1900-2000 calories for someone who weighs 128 lbs.  This sunday, I counted my intake at about 2600-2700 calories.  
My real question comes down to this: does intense physical exercise programs increase the metabolism on "off days"?  I feel like I am eating properly for the most part, avoiding candy bars, chips, and soda, yet still get the hunger pang after the 2000 calorie mark.  Is there any reason to be concerned?  And if I do begin to see an increase in my body fat calculations, how should I deal with the hunger after what my body needs?  Thank you.

Answer
Hi Chris,

Hunger, your appetite is on your side. Your job is to pay attention to the quality of what goes down your neck, then the quantity will talk care of itself. Your appetite can tell you what you need and how much, you don't need to do calorie math. Make sure refined flour and refined sugar is on your poison list. Read labels, it is a job to avoid it.

YES, muscle mass ups your metabolism so you are burning more just by breathing than you did before you worked out so much.
