I agree with the above poster. If you’re training sometimes 4+ hours a day, you need to eat a shit load of food. Plus, you’re only 15. Don’t worry so much about eating clean, as much as you should worry about eating ENOUGH.
That said, if you’re wondering how to try and eat clean, it takes some prep and discipline.
Here’s what I do and still keep the calories up:
Eat half a dozen eggs in the morning plus two different pieces of fruit (Banana and a mango, or banana and apple, or kiwi, etc)
pack protein bars w/ you to go, AND at least 2 apples and a banana and an orange.
You should always have fruit and protein bars in your backpack.
Eat super high-fat meals at night time that are still semi-clean.
Example: Last night, I at 1100 calories:
2/3lb lean ground beef, lots of cheese, japenlos, peppers, 1 avocado, 16oz of milk (it was hott!).
I buy a lot of fruits, and eat several servings a day (a banana is 100 cal and it doesn’t fill you up: eat a ton of those)
Natural Peanut Butter. Man, I can add 500 calories to my fruit just w/ PB.
Olive Oil. Calories, yet a healthy fat.
If you are always eating, then you aren’t going to be likely to crave some junk.
When I go to a coffee shop or a place like Panera Bread to study, I pack a half pound of turkey w/ me and I add to whatever I order (a salad/sandwich). And, following my rule of course, I always have a protein bar, an apple, an orange, and a banana in my back pack.
As long as you have something like that to hold you over, as soon as you get home, that’s when you can crank out the avocados and beef and chicken and hot sauce.
My 2 cents.
