""Overeating is a major contributor to obesity, yet most treatments overlook the unconscious habits that drive it," said corresponding author Nabil Alshurafa, PhD, associate professor of Preventive Medicine in the Division of Behavioral Medicine and of computer engineering at the McCormick School of Engineering, who was the corresponding author of the new study published in npj Digital Medicine (part of the Nature portfolio of journals)."
"The study yielded thousands of hours of video and sensor data and revealed that overeating is far from one-size-fits-all. Instead, it falls into five distinct patterns: Take-out feasting: Gorging on delivery and take-out meals Evening restaurant reveling: Social dinners leading to excess food intake Evening craving: Late-night snack compulsion Uncontrolled pleasure eating: Spontaneous, joyful binges Stress-driven evening nibbling: Anxiety-fueled grazing"
Sixty adults with obesity wore a necklace, wristband and body camera while using a smartphone app to record meal-related mood and context (for example, who they were with and what they were doing) for two weeks. The wearable system captured thousands of hours of video and sensor recordings that characterized real-world eating behavior with privacy protections. Analysis identified five distinct overeating patterns: take-out feasting, evening restaurant reveling, evening craving, uncontrolled pleasure eating and stress-driven evening nibbling. These patterns reflect interactions among environment, emotion and habit and enable profiling individuals for tailored, context-aware interventions to reduce overeating. The insights support diagnostic profiling and development of wearable-driven prompts, such as smartwatches that detect imminent overeating and guide healthier choices.
