What can you eat to gain weight healthily?

How long and how much do you want?

I gained 20 pounds in two months. The method is simple. I eat and sleep on time. I just eat three bowls of stewed pork ribs soup every day, such as stewed pork ribs with melon, stewed pork ribs with lotus root slices and stewed pork ribs with kelp. ...

Stew soup is thicker, eat meat and drink soup, hehe ... and then it's hard to lose weight. ...
