you can try this as a start
take your current bodyweight, multiply by 20 and start from there
make sure your getting 1-1.5 grams of protein per pound of bodyweight per day and the rest of the calories from carbs(say 2 grams per pound) and fats make up the rest and work up or down from there depending on the feedabck
and keep a fucking diary if you are trying to gain or lose. I dont know how many people say they eat all the time and when they actually write down the shit day to day it gives the opposite picture, same can be said for losing weight as well
example start off could be at the minumum
protein:270 grams proteinx 4=720/1080 cals
carbs: 360x4=1440
fats:120 grams x9=1080
Gives a ratio of 40% Carbs/30%protein/30% fats
Obviously thats just an example of a starting point, you will have to probably adjust those factors to work for you.
Anyways no matter what you do make a plan, keep a diary journal of daily eating and all feedback ie notes on energy, visual fat loss/gain, strength levels etc and stick to the plan for at least a couple weeks before making adjustments as what the hell is the point if you fuck with it daily.
Consisitency will be your best feedback
