Hi Sydney,
I do not have a specific diet.
I make sure to get my 3000 kcal an non-workout days and 3500 kcal on workout days, >200 g of protein every day, and I love fruits, nuts and vegetables.
On woRK days - I work in a steel factory as a screws-and-other-metal-stuff-delivery boy

- I add about 500 extra calories.
I guess I will have to add some more calories though, as I haven´t gained more than one pound since November (actual bodyweight is 80,3-80,5 kg).
I do NOT restrict myself to the classic tuna-meets-chicken-meets-oats-and-rice-low-fat bodybuilding diet.
Sample day could look like that:
2 scoops of whey
2 bagels
->580 kcal, >35 g protein
125 g rice
300 g chicken (or fish)
salad with 125 g cheese (or 50 g nuts) and 10-12 ml olive oil
-> 1100 kcal, >115 g protein
4 slices of wholegrain toast with 100 g peanut butter
-> 1000 kcal, 40 g protein
500 g German quark (pretty much like low-fat cottage cheese)
1 piece of fruit
-> 450 kcal, 65 g protein
= about 3100 kcal, >250 g protein
On workout days I usually add one protein shake and a protein bar/piece of fruit for 500 extra kcal.
