In many areas, obesity research is limited by a need for improved methodology. In particular, accurate, informative but scalable measurement techniques applicable to large studies are required. For example, the assessment of energy expenditure by doubly-labelled water is accurate but too expensive and time-consuming to be applied to large cohorts. Developments in the following areas would be especially useful:
Given that many of these areas are technically complicated, the best results are likely to come from collaborations between health researchers and researchers in other technical and mathematical sciences such as engineering and statistics.
