Is it possible to lose 15 or more pounds in 31 days?

im a 6'1, 20 year old male. very active with a very clean diet with 15% percent of body fat. losing 15 pounds would put my body fat percentage below 10% which where i want to be. so do you think i can burn 15lbs or more?? and if not in 31 days what about 50 days...
