Long-term fatigue due to overtraining can lead to weight loss as a potential physical consequence. When an individual overtrains, the body experiences a state of stress that can elevate cortisol levels, a hormone that, among other functions, can influence metabolism and promote the breakdown of fat and muscle tissue for energy. As the body struggles to recover and maintain homeostasis during periods of overtraining, it may start to use stored energy supplies more rapidly, potentially leading to weight loss.

In this context, muscle hypertrophy, increased endurance capacity, and weight gain are generally not associated with overtraining. Instead, persistent fatigue and insufficient recovery can hinder muscle growth and endurance improvements, while weight gain could occur due to various factors but is not a direct consequence of overtraining. Weight loss emerges as a more likely outcome due to the body's adaptive responses to prolonged fatigue and stress.
