NCT ID NCT07371559
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new method that uses 3D scanning and photos to estimate the calories in meals. Researchers will recruit 200 volunteers who will choose foods from a buffet, and the team will compare the calorie estimates from a smartphone app with actual measurements. The goal is to improve how we track energy intake in dietary research.
