6 egg whites, 1 cup oatmeal, 1 orange = 2/40/30/306
3 chicken breast (1lb cooked), 2 cups rice = 26/90/98/966
10oz steak, 2 cups veg = 40/48/87/946
1 protein shake w/ water = 1/4/26/130
That puts you around 69g fat, 182g carbs, 262g protein and 2,348 calories.
That's your problem man. There's no way you're gaining big weight eating 2300 calories. I bulk dirty so take this with a grain of salt but I'm taking in close to 4,000 cals when bulking. Your carbs are super low to be bulking. You deserve credit for eating so clean but DMZ is no magic, if you are in a caloric deficit (which if you are young and working our hard regularly then you are) you're not going to put on big weight.
