eat more!

Have you tried eating fatty food? 100 gr of peanuts are 550+ calories, the same goes with hazelnuts, almonds, walnuts, etc. A tablespoon of olive oil goes almost to 100 calories., same with butter. 1 scoop of any protein + 30 grs of any nut + 1 tablespoon of peanut butter + 1 banana + anything you like = +600 calories intake very easy. Also a little bit of olive oil in your meals and that's it. You'll be gaining weight quickly.

@@userfujiwara5414 wow, that's a lot of detail. I'll take this into account and try it, for sure! Thanks, appreciate it :)

Same here. I'm a 63kg skinny dude and I'm struggling to gain weight

I'll do more tomorrow!
