People with thin constitution must control the degree of weight gain, not blindly gaining weight, and not eating junk food to gain weight, which will only harm their health. I suggest you know your physical condition first and see if your body fat rate is not within the standard range. Blind weight gain will inadvertently increase visceral fat, which is not worth the loss. So always pay attention to your physical condition. I suggest you use it to measure, and then he will give a more reasonable adjustment plan to keep your weight within a certain range.
