Symbol opinion vote Comment: You need to be document that the study is widely accepted by scientists in the field, and there need to be specific references to that effect. For a guide to the best types of reference, see WP:MEDRS. The reference must be by third parties, not just the authors of the study. The references should not just be listed in the references section, but given as numbered footnotes to the specific statements which they document in the article itself

You also need to be more selective about your use of external links. If they are references providing substantial coverage from third-party independent reliable sources, especially professional or scientific sources, they belong as references, not external links. If they are mere comments in the popular press, or on web site,s, they should not be given at all. DGG ( talk ) 01:56, 12 August 2015 (UTC)

Clean Plate, or the Clean Plate Club, is a study conducted by Brain Wansink and co-author Katherine Abowd Johnson, from the Cornell Food and Brand Lab. The results of the study show that the average adult will eat 92% of the food they serve themselves.[1] The purpose of this study is to assist in correcting choices that may lead to overeating, and changing the environment rather than the mindset of the consumer. The Clean Plate study exemplifies some of the underlying psychological effects of consumption norms alongside the effects of portions sizes, and how they may mutually have an impact on weight gain over time.

Method

Out of the 127 studies that were reviewed, 14 studies were identified to meet the eligibility criteria. These 14 studies analyzed 1179 different participants from 7 developed countries: the US, Canada, France, Taiwan, Finland, and the Netherlands. The diners served themselves one food item. Meta-analysis was used to estimate the amount of self-served food that was consumed under various conditions, i.e. population, food, and situational cues. The aggregate analysis took studies where participants served themselves food and the intake amount was measured. Based on data that was provided, a conservative standard deviation of 10% was determined.

Results

The results showed that adults consistently consumed 91.7% of the food they served themselves. The results were higher when a person was not distracted (97.1%) than when a person was with someone, or watching TV (88.8%), and higher for meals (92.8%) than for snacks (76.1%). The percentage eaten between lab setting (90.7) and field setting (91.9) did not vary. Male and female adults consumed similar percentages as well (90.3% vs. 91.8%). In the analysis of 326 participants under the age of 18, the results showed that the average child ate 59% of the food they served themselves.[2]

Discussion

These results show that for the vast majority of people, their visual cue for when to stop eating is when they see a clean plate in front of them.[3] Johnson says “Part of why we finish most of what we serve is because we are aware enough to know how much we’ll want in the first place.” Other studies have been conducted on children classified as restrained and unrestrained eaters, according to the restraint scale (Herman & Polivy, 1980.)[4] It has been found that children who have been conditioned to clean their plate may end up requesting more food when they are away from home.[5] This study aims to be a preliminarily investigation to assist in child obesity, public health, and nutrition researchers in better understanding eating behavior as well as solutions to overeating.
