Surplus food overworks the digestive system, causing chills, faintness, and mental numbness.

Original passage

The surplus food burdens the system and produces morbid, feverish conditions. It calls an undue amount of blood to the stomach, causing the limbs and extremities to chill quickly. It lays a heavy tax on the digestive organs, and when these organs have accomplished their task, there is a feeling of faintness or languor. Some who are continually overeating call this all-gone feeling hunger; but it is caused by the over-worked condition of the digestive organs. At times there is numbness of the brain, with disinclination to mental or physical effort.
