Hello. There are few reasons of being underweight.
It can be due to lack of physical activity, hereditary, eating disorders and chronic diseases
Mainly an underweight person will have lower immunity levels and can easily fall prey to illness and infections and moreover the rate of recovery in underweight people is slower than in healthy individuals. Eat your meals on time and add 500 calories. The amount of calories you take in should be more than the amount of calories you burn. Never skip your breakfast.(always prefer homemade food)
Sleep on time. If you sleep late, that eventually disturbs hormones in your body. Basically it is important to sleep before midnight because that sleep is known to be the healing sleep for the body but unfortunately due to our lifestyles most of the people don't get it these days. Also gets 7 to 8 hours of sleep each day.
Avoid junk food at any cost.
Eat calorie dense food (which includes calorie dense milk shakes). Gaining weight involves consistent eating. Increase your portion size. If for example you usually eat 3 chapatis, then start eating 4th one.
