Abstract
Overall, this review provides the most conclusive evidence to date that acting to reduce the size, availability and appeal of larger-sized portions, packages and tableware has potential to reduce the quantities of food that people select and consume by meaningful amounts. However, it is uncertain whether reducing portions at the smaller end of the size range can be as effective in reducing food consumption as reductions at the larger end of the range. Our findings highlight the need for further research that aims to reduce uncertainties about these effects and address identified gaps in the evidence base, including not having enough evidence for longer-term effects and the absence of evidence about alcohol products.
Highlights
The updated search conducted up to 30 January 2015 identified 11 further eligible studies published during 2013 and 2014

Summary
The updated search conducted up to 30 January 2015 identified 11 further eligible studies published during 2013 and 2014 (see Search methods for identification of studies, Results of the search and Appendix 1). Examples include the portion size of alcoholic beverages served in bars or of foods served in restaurants, at a bu et or in the home, such as portions of a dish served to restaurant customers (Diliberti 2004), the size or shape of plates or glasses used to serve products (Shah 2011), and the number or length of cigarettes in packets sold in shops (Russell 1980) In this context, the intervention involves manipulation of the size or physical dimensions of a food, alcohol or tobacco product, its packaging or the tableware used in its consumption. Comparisons of interest are between products, packages or items of tableware that di er only in terms of these properties
