Obesity is a chronic disease. According to WHO's definition, it is known to have abnormal or excessive fat accumulation in the body. We thought that gaining 2-3 kg in a year is not a big deal, but in the long run, if weight gain is not well-controlled, we are also increasing the risk of getting diseases.
