Serving sizes


To reduce unintended overconsumption and encourage portion control.


Excess caloric intake, especially through easy access to oversized meal options, can lead to excess weight gain and obesity. Some studies show that individuals will serve and eat more food when provided with larger plates and bowls compared to smaller ones. In addition, larger portions of energy-dense foods also promote overconsumption. Therefore, reducing the size and caloric content of meals can reduce the likelihood of unintended overeating, thereby encouraging healthier eating habits.
