The Weight Gain Calculator is designed to help individuals who are underweight or looking to build muscle by determining how many calories they need to consume daily to gain weight safely and effectively. By factoring in your age, gender, weight, height, and activity level, the tool provides personalized recommendations for daily caloric intake and macronutrient balance. It supports a gradual and healthy approach to weight gain, focusing on lean muscle development rather than excess fat accumulation. Whether you're recovering from illness, boosting athletic performance, or enhancing your physique, this calculator helps you set realistic goals and track your progress confidently.
