Official title

Food Addiction, Binge Eating Disorder and Taste Perception in Subjects With Obesity

Overview

The identification of safe and effective strategies for weight loss and long-term maintenance is critical to reduce the alarming prevalence of obesity worldwide and mitigate obesity-associated health risks. Specifically, Binge Eating (BE) and Food Addiction (FA) behaviors are well known causes of failed weight loss and weight regain. The definitions of their clinical phenotypes are currently evolving. Recent evidence suggests that food choices, behavior and reward may be driven also by taste perception. The hypothesis of this study is that subjects with dysfunctional eating behavior have different taste thresholds compared to obese subjects without eating disorders, and that this characteristic influences food choice and eating behavior. Identifying a difference in the taste thresholds between obese with and without eating disorder will allow us to understand why certain individuals over-consume or binge on densely caloric foods and to give them a tailored dietary treatment so as to maintain weight loss for a long time. The Binge eating and Food Addiction is assessed using Binge Eating Scale and Yale Food Addiction Scale 2.0. Subjects with obesity recruited are divided in 4 groups: without eating disorder, with food addiction (FA), with binge eating (BE) and with FA + BE. In these groups sweet and salty taste will be measured with the 3-Alternative-Forced-Choice method.

Primary outcome measures

  • sweet taste recognition threshold [Time frame: baseline]
  • salt taste recognition threshold [Time frame: baseline]
Secondary outcome measures (3)
  • prevalence of binge eating (BE) [Time frame: baseline]
  • prevalence of Food Addiction (FA) [Time frame: baseline]
  • prevalence of Food Addiction (FA) + Binge Eating (BE) [Time frame: baseline]
