How much weight can you gain safely in a week?

A safe and sustainable weight gain is typically around 0.5 to 1 pound per week, depending on individual factors like metabolism, activity level, and overall health. Gaining more than this can lead to excess fat accumulation rather than muscle growth, especially if done through unhealthy eating habits. It's important to focus on nutrient-dense foods and strength training to support lean muscle gain. Always consult with a healthcare or nutrition professional for personalized advice.
