People often eat based on visual cues rather than their actual hunger levels, leading to overeating. An experiment with a refillable soup bowl revealed that participants consumed 73% more soup without feeling any fuller. To combat this, it's suggested to serve snacks in bowls instead of eating directly from the bag, which can help reduce consumption by 20% to 25%. Interestingly, individuals tend to eat more of what they perceive as healthy foods, further complicating mindful eating practices.
