A complete personal nutrition, health, wellness and fitness monitor is disclosed that captures, monitors, and tracks many relevant health and wellness factors. Image of all consumed items is captured with a three dimensional reference object, matched to reference images in a database in terms of shape, color, size and texture, identified, and the volume of the respective items is determined. In addition, molecular optical fingerprinting of consumable products provides information about actual food composition, including vitamins and contaminants that affect food safety. Using energy and nutrition information of items in another database, full nutritional content and energy is evaluated for all of the items in the image. Combined with activity monitoring that captures energy output, the monitor actively tracks overall energy balance and nutritional content for every consumable item in real time, and makes proactive recommendations with respect to nutrition, exercise, and general lifestyle for overall nutrition, health, wellness, and fitness.
