bro u're reli skinny man, but keep it up and eat 5-6 times a day.
I'm currently (morning after goin to toilet weight) 61kg , height : 175cm.
Struggling to keep eating on time, only lifting dumbells and pushup 3 times a week.
planning to get to 70kg and then only start on abs hehe..

this was my weight gain plan last year, from 60kg to 68kg in 1 month.
Mixed with some pushup's and dumbell weights, when I came bk to malaysia for holidays I was buffed.

Morning
4 breads with peanut butter
half can of red beans
3 scrambled eggs

In between have some snacks such as fruits, banana.

Afternoon
Rice (alot of rice) + vegetable (brocolli, cabbage) + 2 drumsticks.

Evening ( workout ) mon, wed, fri.

Night
Rice (alot of rice) + vegetable (brocolli, cabbage) + 2 drumsticks.

Before sleep 11pm eat 3 egg whites.

12am sleep.

gaining weight takes a lot of dedication and most importantly time.
You can say that I force feed myself into eating the same thing for 1 month.
For the first week or so I'm like "not bad", second week and so on...
