Hi mate, it's nice to see that your open about your diet and willing to change it. Some may not agree with this but b/c your 16 I wouldn't take your diet to extremes like most of us do (I dont mean to sound patronising, but wait until ure a little older

).
Im no expert on healthy diets, but generally eat clean foods like pastas, rice, breads, im not too sure of good meats (im a veggie) but chicken and tuna seem to be good meats/fish/poultry/whatever lol.
Have a search on the forum for "clean diet" or somthing, im sure you will find plenty of information!
But taking any fat burner on a bad diet probably isn't going to help much
P.S for breakfast I usually eat an apple,
protein shake and two slices of bread. What you eat really depends on wheter you are bulking, cutting or just looking to maintain your weight.
Remeber:
"calories out > calories in" = weight loss
"calories out < calories in" =
weight gain
"calories out = calories in" = maintainance of current weight
Hope I could help!
