Misconception on Work and energy conservation

It is said that when work is done energy is lost. But when a man runs in a circular path and reaches the starting point, then the work done is zero but energy is lost. (Divyam asked)
Answer: The work done here is not zero, work is done and energy is spent to overcome friction. Though he is reaching the same point, he is moving against a non conservative force, friction (where the work done in a closed path is not zero)
