Summary
This scoping review maps protocols for reward eating in obesity treatment. Research shows a growing interest in diverse interventions, including diet and training programs, for managing obesity.
Area of Science:
- Behavioral Science
- Obesity Research
- Dietary Interventions
Background:
- Reward eating is a significant factor in obesity.
- Effective interventions for reward eating are crucial for obesity management.
- Existing literature lacks a comprehensive overview of current protocols.
Purpose of the Study:
- To systematically map and categorize protocols addressing reward eating in scientific literature.
- To identify trends and common approaches in reward eating interventions.
- To provide an overview of the research landscape for future studies.
Main Methods:
- A scoping review was conducted following PRISMA-ScR guidelines.
- Literature search across Lilacs, PsycInfo, and PubMed databases (2014-2024).
- Analysis and categorization of 22 selected articles into distinct protocol groups.
Main Results:
- Twenty-two articles published between 2014 and 2024 were analyzed.
- Protocols were categorized into diet (n=8), specific training (n=5), physical exercise (n=2), apps (n=2), phytotherapeutics (n=1), and mixed (n=4).
- A notable increase in research on reward eating in obesity treatments over the last decade was observed.
Conclusions:
- There is a growing scientific interest in understanding and addressing reward eating in obesity.
- Diverse protocols, including dietary, behavioral, and technological approaches, are being explored.
- This review highlights the ongoing pursuit of innovative methods for obesity management.

01:23Binge Eating Disorders
168
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

01:20Taste Buds and Receptors
2.8K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

01:30Bulimia Nervosa
194
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

01:30Regulation of Food Intake
370
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
