I am 23 years old weighing 44kg. is this weight good for my health?

Age 23 - 97 Pounds : This is on the low side. Your height is also important to know. Either way, the answer depends on your current state of health, nutrition, immune status and family history. There is no penalty for being thin if you are eating right, exercising responsibly, and metabolizing optimally. You might want to make an appointment with your doctor and discuss your weight concerns.
