Summary
Obese individuals show an unconscious preference for large food portions, contrasting with their stated negative attitudes. This implicit preference for larger portions in obesity is not due to misperception.
Area of Science:
- Psychology
- Behavioral Science
- Nutrition Science
Background:
- Obesity is a complex condition influenced by various factors, including food preferences.
- Understanding the interplay between implicit and explicit food preferences is crucial for obesity research.
Purpose of the Study:
- To investigate implicit food portion preferences in individuals with obesity.
- To examine discrepancies between implicit and explicit food portion preferences in obese and non-obese individuals.
Main Methods:
- Utilized the affective priming paradigm to assess implicit food portion preferences.
- Employed self-reported affective ratings and a portion judgment task to measure explicit preferences and potential misperceptions.
Main Results:
- Obese participants exhibited an implicit preference for large food portions, unlike the non-obese group.
- Explicit preferences in the obese group indicated a negative attitude towards large portions, revealing a discrepancy.
- No evidence of portion misperception was found in the obese group.
Conclusions:
- Obese individuals demonstrate a conflict between their unconscious inclination towards larger food portions and their consciously reported preferences.
- Social desirability or reduced self-awareness may explain the divergence between implicit and explicit preferences in obesity.

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

01:25Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
363
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

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.

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
