Bro, you seems like a hard gainer. I understand how it feels to
be skinny and no matter what you eat, you'll not grow fat.
First hit the gym 2 times a week, eat 5 meals a day. After which
when you start putting on weight, adjust your diet according to
your lean body weight.
if you're about 54kg range, aim around 60kg first. After you hit
your target, aim 65kg and so on.
if necessary, put in weight gainer at the start for about 3
months.
