Can beer help me to gain weight?

Beer will make you gain weight in all the wrong places. If you want to gain weight and look good, eating a crap load of vegetables and meat, and then exercising regularly, will help you gain a lot of weight, and that weight will be healthy and attractive. I suggest buying some protein shakes, eating a good diet, and doing some strength training exercises every other day. That will help immensely and you won't get a beer gut.
