Whenever you want to build muscle and bulk up you will need to have a diet that is rich in calories and protein.
Calories are important because most skinny men have a very fast metabolism. This means that your body quickly processes food and oftentimes it will waste a lot of calories. In this case you are going to need to eat more calories in order to gain muscle mass. You will want to multiply your body weight by 18 in order to figure out how many calories you need each day. So, if you weigh 150 lbs you would need 2,700 calories (150 x 18 = 2700). The best sources of calories include oats, milk, nuts and fruit.
Protein is important because it is quickly changed into amino acids, the building blocks for muscle growth. You will need to eat 1g of protein for ever 1lb of bodyweight. So, if you weigh 160lb, then you will want to have at least 160g of protein in your diet each day. The best sources of protein include chicken, lean red meat, eggs and tuna.
