Personality and morbid obesity. Implications for dietary management through behavior modification

Area of Science:

• Psychology
• Psychiatry
• Behavioral Science

Background:

• Psychological investigations have not identified specific personality types or psychodynamic conflicts unique to moderately and massively obese individuals.
• Psychological issues like anxiety, depression, and low self-esteem in obese persons appear to be consequences, rather than causes, of their weight status.

Purpose of the Study:

• To explore the psychological underpinnings of obesity, particularly morbid obesity.
• To evaluate the effectiveness of psychological and behavioral interventions for weight management in obese populations.

Main Methods:

• Review of psychological investigations into obesity.
• Analysis of psychological problems associated with obesity.
• Examination of addictive behavior patterns in morbidly obese individuals.
• Assessment of behavior modification programs for eating patterns and food consumption self-management.

Main Results:

• No distinct personality type or psychodynamic conflict pattern was found in moderately and massively obese individuals.
• Psychological problems in the obese are often a result of obesity, not its cause.
• Morbid obesity exhibits addictive behavior patterns similar to other addictions, suggesting a significant substance abuse component in the eating disorder.
• Behavior modification programs yielded moderate success, with an average weight loss of 7–16 pounds post-treatment.

Conclusions:

• Psychological distress is frequently a consequence of obesity rather than a predisposing factor.
• Morbid obesity may be characterized by addictive behaviors, highlighting a link to substance abuse.
• While behavior modification can lead to moderate weight loss, it is not sufficiently effective for the majority of morbidly obese individuals seeking substantial weight reduction.
