Is it possible to lose 4 pounds of muscle mass in 1 month?

Losing 4 pounds of muscle mass in one month is not realistically achievable and could indicate an underlying health condition. Muscle loss occurs over time due to various factors such as aging, lack of physical activity, or severe calorie restriction.

To safely lose weight, including fat and preserving muscle mass, aiming to lose 1-2 pounds per week through a combination of healthy diet, exercise, and proper rest is recommended. Drastic muscle loss in a short period can negatively affect overall health and metabolism. Consult with a healthcare professional or registered dietitian to create a personalized and safe weight loss plan that prioritizes maintaining muscle mass.
