You are doing well. Remember muscle weighs more that fat.
With the lacrosse and other athletic activities, I would not lower your
carb intake.

Do you have time to chart your foods at www.fitday.com?
If so you will see your percentages, protein, fat and carbs.
Make sure you eat enough fats.

Are you taking supplements? Your body is still growiing until age 25, so you are not like a lot of us over that age. You need to make sure you are getting proper nutrition/vitamins & Minerals even if through supplements.

Good like!
