A body mass index (BMI) calculation would be a more accurate way to determine if 115 pounds is a healthy weight for a 15-year-old male who is 5'7". However, based on averages, a weight of 115 pounds may be considered on the lower side for a 15-year-old male of that height. It is important to consider factors such as muscle mass and overall health in addition to weight when determining if someone is considered "skinny." Consulting with a healthcare provider would provide the most accurate assessment.
