Weight gain refers to the process of intentionally increasing one’s body weight, typically through a combination of increased calorie intake and resistance training. It is often sought by individuals who are underweight, have a low body mass index (BMI), or wish to improve their athletic performance or overall health.
Gaining weight can offer several benefits. For those who are underweight, it can help them reach a healthier weight range and reduce the risk of health problems associated with being underweight, such as malnutrition, fatigue, and impaired immune function. Additionally, gaining weight can enhance athletic performance by increasing muscle mass and strength, which is crucial for activities such as weightlifting, sprinting, and jumping.
