food portion size to food and energy intake Project Code: N09021
University of Ulster The burgeoning rates of obesity in
genetically stable populations suggest that an increasingly
obesogenic environment is the major driving force behind this
epidemic. Increased food portion size may be facilitating excess
energy intake (EI) and a higher risk of overweight and obesity.
The assessment of associations between food portion size and
adiposity in free-living adults is extremely limited. Portion
size has been demonstrated to positively influence EI in adults
under semi-controlled laboratory conditions, but these findings
have been specific to the US and the extent to which these
findings would be relevant to the UK population is unknown at
present. 1. Analysis of food intake data from the National Diet
and Nutrition Survey (NDNS) of British adults (n=1519) to
determine the odds ratio for obesity associated with consuming
larger quantities of different fo
