okay so i just figured out my TDEE FINALLY and its 2448, im 5 foot 6/7 and im 145, i just calculated my caloric intake daily and its around 2100 calories which would explain why im getting cut up, which doesnt really kill me considering its summer and im 19 but i was wondering, where does the bulk of your calories come from?

is it your carb sources? cause i can always add another dosage of 1/2 cup of oatmeal PPWO instead of broccoli and that would up it a little bit, but still, i feel like my meat sources arent giving me enough calories and with the rest of my diet consisting of either whey shakes post workout or broccoli, my diet is just not right

help is appreciated, thank you
