Cachexia in advanced cancer can be very upsetting. The adductor hallucis is a two-headed muscle that is responsible for flexing and contracting the big toe, and reinforcing the arch of the foot.

He believes that at its core cachexia is "more of a host response that's evolved to fight fasting, injury, or disease," he said. During this response, the body is trying to obtain additional energy stores from muscle, in the form of amino acids, to convert into glucose to keep the brain functioning.
