Hi, my problem is that my weight loss has stalled despite regular activity, sprints, and a large deficit. Sixteen, 6 foot, and 195 lbs. (Down from 250!) My kcal intake is about 1500-1800 a day, mostly protein and fat. Should I add more since im stalled? I lift 3/week, sprint, attend school where I'm walking across a rather large campus, and walk briskly maybe 7 hours a week. Up calories?
