A June 2021 study by Pennsylvania State University said,
"Although studies have consistently found that people eat more when they are served larger portions, less is known about why this happens or why some people are more responsive to the effects of large portions than others,"
"This is one of the first studies to explore whether the characteristics of eating speed and bite size have an effect on people's food consumption in response to larger portions."
"Based on our findings, being aware of portion size, slowing down when you eat and taking smaller bites of food could help avoid overconsumption,"
"Also, since people eat more when served more, overconsumption of calories from large portions can be reduced by choosing foods that have less calories per bite. This lets you eat the same filling portions of foods while consuming fewer calories."
