hey max,

i'm exactly like you. was 54kg at 174cm 6 months back. i've been hitting the gym and so far my weight has reached the minimum cutoff point of 60kg.
there's no other option for body sizes like ours (ectomorphs) other than lifting weights. the good thing is about being skinny is that your muscles will have higher definition, thus you will look more ripped.

try hitting the gym seriously, take a look at the stickies in this section - they offer some great advice for beginners. time to show that female colleague of yours.

p/s: oh and don't forget to eat like there's no tomorrow.

i have no exact/specific diet routine which i follow - to me eating habits should be flexible (i'm speaking for the general person here). most people will say cut down on the carbs, no fat etc but really there is much more leeway than you think.

being skinny, i eat just about anything i can get my hands on - rice, rendang, chicken pieces, peanut butter/tuna sandwiches, fruits, half/full boiled eggs. main thing is to eat consistently (i.e 6 meals a day), and never go hungry.

couple that with some solid weight lifting and you should grow in no time bro.
