What are some easy ways to gain weight?

Eat more food including starches: potatoes, breads.............

Lots of calories, carbs, and protein shakes. I started eating 5000 calories and 200 grams of protein a day and in a month in a half ive gained 25 pounds

uhm, eating a higher amount of calories each day without working out. lol mostly stuff with lots of sugar or greasy food like pizza. idrk, sorry cx
