how i figure out how many calories i need to eat

start my diet like this I take my lean mass and I eat about that many grams of carbs, then i eat 1.5 to 2 times my lean mass in grams of protien, also I eat about 30 grams of fat
as I gothrew my diet I make adjustments to carbs sources first.
ex: switch from brown rice to yams
then I may lower fat or adjust carbs slightly, finaly towards the end i take fat out completely
i eat the same diet every day as long as im still making improvements at a good pace.
i usually dont have to start cycling carbs till last four weeks
food sources:
eggs wites
egg yolk
chicken breast
flank steak
tuna
brown rice
yams
brocolli
whey protien
