Marco refers to macronutrients - carbs / proteins / fats.
The info you gave in this post is excellent - it gives great insight as to your body type and challenges - this way you can get input from those that respond exactly the same as you do.
My suggestion would be to do this: Incorporate this post and your other in one thread : meaning outline your stats and you goals plus your body responses (ie: lose fat easily but tough time gaining muscle)
After outlining this figure out caloric requirements. To figure out your daily caloric needs you should calculate your TDEE (total daily energy expenditure). If your goal is gaining mass you would increase the amount of calories required on a daily basis - to cut you would decrease. There are a few way to estimate tdee but this link exlains it pretty well:

At that point you could figure your current diet out and list the meals with macros - totaling at the bottom for daily totals or you could come up with your own diet and have members help you tweak it. A genral rule (just a guidline) is that 40% calories from carbs / 40% from protein and 20% from fat. Fat is 9 cals per gram , pro and carbs are 4 cals per gram. Again nothing is etched in stone when it comes to diet and that needs to be remebered - you can , will and should tweak it to maximize it sepcifically for you. This will involve inoput from others that have same goals , challenges and strenghts as you and first and formost from personal experience. The good news is once you figure it out you know how to maximize your diet for you from this point forward. A general rule when trying toi add mass is 500 cals over tdee - however you may require more if that doesnt suffice in gaining - ie : little muscle is gained and no fat gained.
I hope this doesnt sound too daunting - it really isnt and the knowledge you gain as far as foods , diet , personal response you will have forever and can easily draw upon down the road to set your diet up for your personal success. Best of luck and agin looking forward to your post....
