Researchers with interests in human eating behaviour from disciplines as diverse as nutrition, food science, sensory science and psychology all need reliable and reproducible measures of appetite and intake. Current approaches to measuring intake and appetite are summarised in this chapter, putting these measures into historical context. The initial focus is on food intake, noting the differences in approach between acute intake typically measured under laboratory conditions and long-term free-living intake estimated by diet diaries and food frequency questionnaires. The strengths and weaknesses inherent in each approach are discussed, along with an evidence-based assessment of the critical issues that need to be addressed for successful study design. The use of microstructural techniques based around the Universal Eating Monitor approach allows discussion of the added value of collecting information on meal duration, eating rate, bite-size etc. Focus then switches to measures of appetite, detailing different scales used to measure the subjective experience of hunger and fullness, the two key measures of appetite, again with consideration of strengths and weaknesses of each approach. However, although measurement of either intake or appetite alone can be informative, the chapter shows how studies that examine inter-relationships between measures provides the most detailed account of ingestion, and allows greater clarity when examining mechanisms underlying behaviour. The chapter ends with a case study which illustrates the stages needed to design a detailed appetite investigation to provide the reader with an example of best practice.
