My body fat percentage is 16 and I was wondering how many pounds would I have to lose to go down to 15 percent.
I'm a male, weight-141, waist size- 31 inches, neck-14 inches, wrist-7 inches, height- 5 foot 10 inches.

You're 5'10" and you weigh 141? You're in decent shape... skinny if anything.

I suggest you simply watch what you eat and start an exercise routine... cardio and weight lifting.
