What the test subjects did not know was that every second participant ate their soup from a plate that was slowly refilled via a tube in the bottom. The result: the test subjects\u201e hunger was significantly influenced by this manipulation. The test subjects with the refill plates ate 73 per cent more soup than the participants with normal plates. What is even more astonishing is that the involuntary \u201cextra eaters\" did not feel any fuller than the others in a subsequent survey, nor did they realise that they had consumed significantly more calories. Regardless of who had eaten which portion - everyone reported roughly the same level of satiety.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201ePeople use their eyes, not their stomachs, to count calories.\u201c Apparently, the amount of food is estimated before and during a meal based on visual criteria. This estimate then shapes our expectations and reduces the reliability of our self-assessment when eating. As these processes take place unconsciously, there is a risk of overeating. A simple trick can be used to reduce the amount of calories: smaller plates that make even modest meals look big.<\/p>\n\n\n<div  class=\"spacer_wrap\" aria-hidden=\"true\"><div class=\"wp-block-spacer inner-sm\" style=\"height:calc(100px * 0.4)\" aria-hidden=\"true\"><\/div><div class=\"wp-block-spacer inner-md\" style=\"height:calc(100px * 0.6)\" aria-hidden=\"true\"><\/div><div class=\"wp-block-spacer inner-lg\" style=\"height:calc(100px * 0.8)\" aria-hidden=\"true\"><\/div><div class=\"wp-block-spacer inner-xl\" style=\"height:100px\" aria-hidden=\"true\"><\/div><\/div>\n\n\n<hr class=\"wp-block-separator has-text-color has-color-22-color has-alpha-channel-opacity has-color-22-background-color has-background is-style-wide\"\/>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Sources:<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wansink, B.\/Painter, E.\/North, J.: Bottomless Bowls: Why Visual Cues of Portion Size May Influence Intake; in: Obesity Research, Vol. 13, No. 1, January 2005, pp. 93-100.
