The Assisted Capacity Device Calculator (AC-DC) is an aide apparatus to help people manage their health by, among other things, totaling their daily intake of food and nutrients in their body by calculating weight, water intake, and waste while also calculating their total calorie expenditure. The apparatus is further constructed to identify the various factors that increase a persons body weight resulting from imbalances between caloric energy intake from food and caloric energy expenditure thru exercise, body heat, metabolic rate, etc.
