Eating Behaviors and Disorders Overview

Hunger and Eating Behaviors

• Hunger is influenced by social factors, with individuals often consuming more when around others.
• Eating habits can vary depending on whether a person is alone or in a social setting.

Obesity and Eating Disorders

• Obesity is characterized by the excessive buildup of body fat.
• Body Mass Index (BMI) is used to calculate obesity.
• A significant percentage of the population (approximately 30% obese and 35% overweight) is affected by obesity.
• Anorexia nervosa is an eating disorder characterized by insufficient food intake to maintain a healthy weight.
• Individuals with anorexia often exhibit perfectionistic tendencies in other aspects of their lives.
• The condition can damage heart muscles.
• Bulimia nervosa involves episodes of binge eating, followed by purging, sometimes consuming up to 20,000 calories at once.
• Long-term effects may include lingering depression, even after apparent recovery.
• Bulimics often crave large quantities of highly palatable foods (influenced by Western media and culture) which can reinforce the repetitive nature of their eating behaviors.

Motivation and Drives

• Motivation is a process assessing the value of an outcome, influencing the desire for something at a particular time.
• Drive is a state of restlessness prompting actions to alleviate the discomfort (e.g., eating when hungry).

Types of Motivation

• Extrinsic motivation involves engaging in an activity for rewards or punishments.
• Intrinsic motivation is the drive to act for the inherent satisfaction of the activity.
• Individuals often experience conflicting motivations simultaneously.

Hierarchy of Needs

• Physiological needs, including food, water, warmth, and rest are the most basic.
• Safety needs, like security and safety, are the next tier of importance.
• Belongingness and love needs, encompassing intimate relationships and friendships, come next.
• Esteem needs include prestige and feelings of accomplishment.
• Self-actualization, representing the fulfillment of potential through creative pursuits, is the highest level.

Homeostasis and Incentives

• Homeostasis is the body's tendency to maintain optimal internal conditions, including anticipating future needs (like eating even when not hungry to prevent future hunger).
• Incentives are external stimuli that encourage action, such as rewards.
