It's easier to get fat, unless you are a very special gene, and very few people can't gain weight.

Eat more foods that contain fat, grease and sugar. Of course, at the same time, don't lack other substances necessary for human body, such as protein, inorganic salts and vitamins. What is needed is more rest, and sleep is the best rest.

For example: in the morning, have a cup of milk, soybean milk or sugar water, and then eat some desserts such as bread and cake; At noon, you can eat some meat (do not avoid fat), rice and vegetables, such as vermicelli potatoes with more starch. It is recommended to add a tomato to supplement a lot of vitamins. Eat nutritious food at night, and add another meal half an hour before going to bed, because eating at night is the easiest way to gain weight.
