The author presents a revised, expanded program of dietetic economy centered on slow eating and thorough mastication, arguing that careful chewing conserves energy, prevents overindulgence, and improves mental and physical performance. The text critiques social hospitality and habitual gluttony, recommends aesthetic and economical approaches to feeding, and treats bowel function and excreta as important diagnostic indicators. Practical guidance is illustrated with experimental observations and corroborating testimony from scientific and clinical sources, and the work interleaves prescriptive advice with reflections on habit, environment, and the broader effects of nutrition on daily efficiency and well-being.
