Adherence of Reporting Energy Intake by a Novel Food Photo Recognition Dietary Assessment App on Morbid Obese Subjects Scheduled for Bariatric Surgery
In Brief
An observational study evaluating Recording of food intake. for Obesity, Morbid and 3 related conditions. Completed, enrolled 54 participants across 1 site.
Detailed Summary
Direct measurements of changes in food selection in humans after RYGB have been limited by the unreliability of patients, which poses significant methodological and conceptual challenges to researchers and study design. Self-monitoring requires time and effort, and many find tracking of dietary intake tedious, which contributes to attrition. Direct measurements, however, represent an essential component in the attempt to understand how RYGB alters eating and food preferences, but laboratory settings preclude a real-life environment. The aim of this study is to investigate changes in food preferences, total energy intake of the three primary macronutrients and meal patterns between obese women (BMI ≥ 35) before and after Roux-en-Y gastric bypass and lean (BMI ≤ 25) and obese (BMI ≥ 35) controls by means of photographic food recognition with a mobile application.
