Body weight refers to the total mass of a person's body, typically measured in units like pounds or kilograms. It is influenced by various factors, including muscle mass, fat mass, bone density, and water retention. Maintaining a healthy body weight is important for overall health and can affect physical performance and well-being. Body weight can be assessed using different methods, such as the Body Mass Index (BMI), which compares weight to height. Understanding body weight helps individuals make informed decisions about their diet and exercise, contributing to a balanced lifestyle and reducing the risk of health issues like obesity and diabetes.
