GOMAD Diet works well for begginners
G = Gallon
O = of
M = Milk
A = a
D = day
obviously this is not the diet for you if you are lactose intolerant
With Basic Milk (150 Callorie Serving 8g Protein) at a gallon a day you will get
16x150 = 2400 callories
16x8 = 128g protein
And that is just from milk, there are other diets out there but the GOMAD seems like the easiest, i am in your class fixing to start bulking
Hope i helped/
