Ok well im about 6 weeks into actually working out hard and i just ordered on wednesday a 10lb. jug of 100% whey for $60 including shipping/handling. I just started today with HIIT training, and let me tell you that will kill you, i hope to see great results. So now for the part i need help w/ ... your knowledge. here is my info....
age:16
weight:180
Height:6'0
bench:205 *thats all im really working on for max other stuff i just lift reps*

And what my daily food usually consists of..
2 Granola bars, either fruit or peanut butter flavor about 150 cals.
a few sticks of stringed cheese
some tuna *not everyday*
-school lunch is usually really bad, so i dont get milk i just drink water w/ normally an orange, and a sandwich and they dont have wheat bread so its white.
normally a salad or something good for me for dinner, sometimes whatever my mom makes which usually isnt bad its normally chicken of some sort.
For a snack i usually take a cup of Raisan bran Crunch and snack on that.
and from when i get home from school to when i go to bed i might consume 1 diet pop.

so now i need some help. I am currently doing a lifting program that has ganied me about 30 pounds in the last 6 weeks, week 7 is the last week, it is for benching. Now if i keep doing HIIT on the opposite days i do my lifting, and keep my eating, close too that *its not the same everyday but usually close* and i use protein Pre and Post workout, what kind of gains will i see from the protein? Should i also be losing my excess fat from HIIT? i would like to see myself drop 15 pounds more of fat, and see how i look then, or if this matters i dont care how much i weigh i just want to look good, first get looking slim then attack the abs, but if i had to guess how much more FAT weight i had to lose i would say 15 pounds. My bodyfat i had done "online" so idk how good of a judgement that is it said 14% b/f. please comment i need to know where i am going and what i should change.
