Brain Imaging and Behavior
|July 6, 2020
Summary
Neuroimaging reveals distinct brain activity patterns in successful versus unsuccessful restrained eaters. Unsuccessful restrained eaters show reduced cognitive control and conflict monitoring in key brain regions.
Area of Science:
- Neuroscience
- Psychology
- Cognitive Science
Background:
- Restrained eating is a common weight loss method for young women, often with limited long-term success.
- Previous research identified personality and behavioral differences between successful and unsuccessful restrained eaters.
- Limited research exists on the neurophysiological underpinnings of successful versus unsuccessful restrained eating.
Purpose of the Study:
- To investigate resting-state brain differences between unsuccessful and successful restrained eaters.
- To identify neurophysiological markers associated with restrained eating success.
Main Methods:
- Assessed resting-state brain activity using neuroimaging techniques.
- Compared brain activity in unsuccessful restrained eaters (N=39) and successful restrained eaters (N=31).
- Utilized regional homogeneity, independent component analysis, and seed-based functional connectivity analyses.
Main Results:
- Unsuccessful restrained eaters exhibited reduced regional homogeneity in the inferior parietal lobe (cognitive control).
- The anterior cingulate cortex (conflict monitoring) showed lower activity in unsuccessful restrained eaters.
- Weaker functional connectivity was observed in frontoparietal networks (cognitive control and conflict monitoring) among unsuccessful restrained eaters.
Conclusions:
- Significant resting-state brain differences exist between successful and unsuccessful restrained eaters.
- These differences are primarily located in brain regions crucial for cognitive control and conflict monitoring.
- Findings suggest neurophysiological factors contribute to the effectiveness of restrained eating strategies.

Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

01:23Binge Eating Disorders
347
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...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

01:24Metabolic States of the Body: Fasting and Starvation
2.5K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

02:16Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

01:30Regulation of Food Intake
2.1K
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...
