Loosing fat help needed.

Hi, I'm Matt. I'm 14 years old and i'm 5'11 and i weigh 64KG (not sure what that is in lbs.) I've been trying to define my abs for around a year now. I run 9-12 miles a week, and i box for 4 hours and a half a week (this includes doing circuits and resistance training too for about 1 hour 30 mins a week.) since i started boxing my abs have started coming through, but very faintly. I use the gym at my school 3 times a week, and i usually work on benchpress, bicep curls, shoulder press. Can anybody help me with what i should eat, and what supplements i should take (i have whey protein powder, but im not sure when to take it , before or after training.) P.S if i dont eat enough for energy, i become very faint and shakey when i box :| does anybody know why this may be?

Thankyou for taking the time to read the essay above haha :D

thats alotta exercise ,  u just wanna stay away from junk food , eat alotta healthy stuff , chicken breast , fish , whole grains , lots of water ..
 
suppliments , take  your whey protein  2 times a day and make sure you get one in you withtin the first hour after exercise, the other u can take anytime in the day before or after your workout , you can take creatine ,, but your only fourteen so  im not sure if u should ,  .. but definatly get a multi vitamin!!
 
 

Thanks for the advice, as of yesterday i've started eating very healthily. No ready meals, high protein, and plain carbs for before i box or run.

Can anybody tell me, are bannas a good snack to each instead of say a packet of crisps? i eat around 2-3 bannanas a day now :)

Thanks
