I swear, force feeding leads to psychological damage, dead serious. It's awful. Way easier to inject yourself with loads of gear and kill yourself in the gym.
That awful feel when it's 9pm and you still need 2000 calories and are full to the brim and feeling bloated, but if you don't eat them, you won't make any gains.
Yep. Definitely. For most of my late teens/early 20s, I ignored how important "eating to grow" is, but eating big is every bit as important- and probably more of a hassle- than lifting big.
Here is a quick, easy, inexpensive way to get about 700-800 calories and about 42 grams of protein:
2 cups of oatmeal
half a banana
1 scoop of Whey Tech Protein Powder (Strawberry goes great with banana)
Grind the oatmeal in the blender first. Put the grinded oatmeal into one of these quart containers.

Put 2 1/3 cup of water in blender add banana and protein powder. Slowly add oatmeal. Should fill quart container almost exactly. Get it down quickly because it starts turning into oatmeal after about 7 minutes.
I used to take this 3-4 times a day and grew like a weed. It is really easy to get down and super cheap. I worked it out to about $24 a week for the food and $50 for a little more than 2 weeks worth of protein powder. If you are bulking, you really don't have to think about your diet if you drink this 3 or 4 times.
