Keeping a diary of food intake and timing is a characteristic of a case study, where researchers closely examine the individual behavior of a single participant or small group of participants. It does not involve manipulating variables or controlling for external factors, as in experimental research. It also does not involve observing and recording the culture and behavior of a group, as in ethnography. Lastly, it does not involve collecting data from a large population, as in survey research.
