Summary
In young adults, specific eating behaviors like cognitive restraint and emotional eating are linked to increased obesity, including higher body mass index (BMI) and body fat. Understanding these connections is key for weight management strategies.
Area of Science:
- Nutrition Science
- Obesity Research
- Behavioral Science
Background:
- Young adulthood is a period of significant weight gain.
- The relationship between eating behaviors and body composition in young adults is not well understood.
Purpose of the Study:
- To examine the association between eating behaviors (cognitive restraint, uncontrolled eating, emotional eating) and body composition in Chilean young adults.
Main Methods:
- Cross-sectional study of 555 Chilean young adults (mean age 22.6 years).
- Used logistic and linear regression to analyze eating behavior scores (Three Factor Eating Questionnaire-R18) against body mass index (BMI), percent body fat (DXA), and central obesity.
- Analyses were stratified by sex and controlled for demographic covariates.
Main Results:
- Cognitive restraint was positively associated with obesity (BMI, % body fat, central obesity).
- Emotional eating correlated with obesity (% body fat, central obesity in both sexes; BMI in women).
- Uncontrolled eating showed no association with adiposity.
Conclusions:
- Cognitive restraint and emotional eating behaviors are linked to higher BMI, increased body fat, and central obesity in Chilean young adults.

01:30Regulation of Food Intake
2.0K
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...

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

01:19Energy Balance
897
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

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...

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.

534
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...
