What this trial studies
This project aims to identify physiological biomarkers associated with food and energy intake to develop an objective tool for estimating dietary intake. The study will involve ten healthy adults who will participate in two visits where they consume high- and low-calorie meals in a randomized order. During these meals, physiological changes such as skin temperature, blood oxygen saturation, and pulse rate will be monitored to assess their correlation with eating behaviors. The goal is to improve the accuracy of dietary intake assessments beyond traditional self-reporting methods.
Why it matters
Potential benefit: If successful, this study could lead to more accurate and objective methods for monitoring dietary intake, benefiting individuals managing their nutrition.
How similar studies have gone: While this approach is novel, similar studies exploring wearable technology for health monitoring have shown promising results.
