2700 is so little granted you're probably not as active as i was in season.
one of my nutrition classes last year i had to figure it out for 2 weeks, i was averaging 4000 a day, and weighed a nice 150lbs, but working out 4-5+ hours a day helps out quite a bit too //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
but ive relaxed a bit over the past month or so, stuff like this makes me realize that when spring comes around and it warms up i need to start running alot more.
best of luck!
