waht is the best food to gain weight? I really need help and advice. For what kind of food I should eat,to get fatter.

Hi I'm new here, I just came across this fetish about a month ago. and now I want to see if I can gain weight, but I have a hard time getting my daily calorie intake. I would need tips and tricks on how to get calories easier during the day. Is there something I should think about to make it easier so that it does not become so difficult?
