Study Notes

Media and Body Image Influence

The media portrays thin women and muscular men as the norm, despite not being representative of the general population.
Exposure to such images in the media increases body dissatisfaction in men and women, including those with different weight statuses like anorexic, bulimic, and pregnant women.
Paradoxically, despite seeing a mix of real people in daily life, exposure to media images doesn't balance out the dissatisfaction.
Daughters tend to reflect their mother's level of body dissatisfaction, possibly due to sharing similar physiques and social pressures.
The media's portrayal of body forms on TV does not align with reality, leading to increased dissatisfaction.
The media's response to public desires does not justify its role in increasing body dissatisfaction.
The current preoccupation with thinness and dieting may be shaping the female and male body towards a sexual ideal.
Throughout history, sexual ideals have shaped the human body form, often exaggerating existing gender differences.
Historical examples include foot binding in China, corsets in Victorian times, and the impact of the women's liberation movement in the 60s.
The psychology of dieting is influenced by body dissatisfaction, leading to restrained eating as a conscious attempt to control body size and food intake.
The restrained eating approach explains why dieting can sometimes lead to weight gain rather than loss.
Dieters tend to show increased consumption after exposure to high-calorie preloads, engaging cognitions against self-imposed food restriction.
