This paper proposes a fuzzy logic diet journaling system based on the premise that food intake is a control system. Past work in fuzzy diet analysis is covered. This continues into a discussion over strengths and weaknesses of the past work and a synthesis of requirements for a fuzzy diet analysis system with food recommendations. The proposed system is described and implemented. Two methods for nutritional feedback, one fuzzy and the other crisp, are compared. A comparison is made between the usefulness of fuzzy and crisp diet data from a user’s perspective.
