A typical meal day if you seriously want to bulk up.
Breakfast - 2 Eggs
Lunch - Chicken & Salad Wholemeal Sandwich
Snack - 1 Piece of fruit
Dinner - 120g Salmon with 4 varieties of green veg mostly. Brown rice if needed 70g.
The example I showed you is probably around 100g protein on food alone, on less than 2,000 calories.
TS, you need to either choose gaining muscle or getting a six pack. Having a six pack is about low BF%, gaining muscle will probably require you to do the opposite. Choose one or the other.
