A major limitation in nutritional science is the lack of understanding of the nutritional intake of free living people. There is an inverse relationship between accuracy of reporting of energy intake by all current nutritional methodologies and body weight. In this pilot study we aim to explore whether using a novel lightweight, wearable micro-camera improves accuracy of dietary intake assessment. Doubly-labelled water (DLW) was used to estimate energy expenditure and intake over a 14-day period over which time participants (n = 6) completed a food diary and wore a micro-camera on 2 of the days. Comparisons were made between the estimated energy intake from reported food diary alone and together with the images from the micro-camera recordings. There was an average daily deficit of 3912kJ using food diaries to estimate energy intake compared to estimated energy expenditure from DLW (p=0.0118) representing an under-reporting rate of 34%. Analysis of food diaries alone showed a significant deficit in estimated daily energy intake compared to estimated intake from food diary analysis with images from the micro-camera recordings (405kJ). Use of the micro-camera images in conjunction with food diaries improves the accuracy of dietary assessment and provides valuable information on macronutrient intake and eating rate. There is a need to develop this recording technique to remove user and assessor bias.
