not for me, for my boyfriend. he's about 20 lbs underweight and needs to gain weight.

he's got a slender build, is fairly active, eats regularly but not too interested in large portions, never been a big eater. eats a lot of junk food (loves mcdonald's). takes no suppliments.

he's always been this size.

he's started on fitday, only a day's worth of info so far.

does anyone have any advice on how he can increase his appetite? he knows he needs more excersize to increase the appetite, are there suppliments etc that might help as well? any advice is appreciated - i figured with all the combined nutrional info you guys possess, someone might have ideas!

here's his fitday (so far...):

p.s. i wish i had this problem. i'd eat the eastern seaboard.
