A modern societal body standard that values both leanness and physical muscle tone is driving unhealthy exercise and eating habits in both men and women. While both genders internalize these pressures from internet platforms to a similar degree, the psychological pathways leading to risky behaviors differ by gender. The research detailing these patterns was published in the journal Sex Roles.
Historically, researchers assessed societal body standards as separate concepts for men and women. The classic cultural expectation for women was extreme thinness, which prioritized low body weight without focusing on strength. The expectation for men was a highly muscular, bulky physique. Now, these separate beauty standards are merging into a centralized body type that researchers call the fit ideal, which appeals to a broad demographic.
This newer appearance standard requires a person to possess very low body fat along with noticeable muscle tone. Achieving this specific balance is biologically difficult for the average person. Getting highly toned often requires a calorie surplus to build muscle mass, while remaining extremely lean requires a calorie deficit to burn fat. Because these physiological states are at odds, the fit ideal is largely an unattainable goal.
The rise of image-focused internet platforms has heavily promoted this athletic aesthetic. Hashtags related to fitness motivation accompany millions of posts featuring lean and toned individuals. While often disguised as content promoting health, these images generally prioritize physical attractiveness over actual well-being. Consuming this type of media puts pressure on users to match an aesthetic that is largely out of reach.
Over time, individuals may absorb these external standards and adopt them as their own personal goals. This psychological process is known as internalization. To better understand how the modern athletic standard impacts physical and mental health once internalized, a team of researchers from Australia and Canada designed a new psychological investigation.
The team was led by behavioral researcher Robyn Louw at Griffith University in Australia, along with colleagues Caroline Donovan, Laura Uhlmann, Kyle T. Ganson, and Timothy Piatkowski. They wanted to test a sociological framework that explains how media and peers influence individual body image.
The framework suggests that social pressures lead people outward to compare their bodies to others. Eventually, they absorb the cultural standard as a personal requirement. This internal pressure is then thought to foster extreme dissatisfaction with one’s own appearance. That dissatisfaction ultimately results in disordered eating and obsessive workout routines as the person desperately tries to change their shape.
Louw and the team recruited 288 adults residing in Australia to complete a series of psychological surveys. The average age of the participants was nearly 23 years old. About 70 percent of the group identified as women. A majority of the group reported being active on image-heavy internet platforms like Instagram and TikTok, with many engaging in weekly weight training.
The surveys asked participants to rate the level of pressure they felt from their peers and from social media regarding their physical appearance. Participants also answered questions designed to measure how often they compared their bodies to others and how deeply they had absorbed the fit ideal as a personal goal. Another section of the survey quantified how dissatisfied participants were with their own physical traits.
Finally, the researchers measured the extent to which participants engaged in harmful behaviors to achieve a lean and muscular body. One measure assessed compulsive exercise, identifying individuals who felt extreme guilt when missing a workout or who exercised despite illness or physical injury. Another measure assessed disordered eating patterns specifically aimed at gaining muscle, such as obsessively tracking protein intake or feeling intense anxiety about meals.
After collecting the survey responses, the team used a statistical modeling technique to review the data. This mathematical approach allows researchers to map out a sequence of relationships between different psychological factors. Rather than just seeing if two things are related, the statistical models help determine if one factor predicts a second, which in turn predicts a third. The researchers created separate models for the men and the women in the study.
The mathematical models revealed that men and women absorbed the fit ideal to an almost identical degree. In both groups, high levels of social media exposure predicted a stronger internal desire to attain a lean and toned body. This finding confirmed the researchers’ hypothesis that the athletic aesthetic represents a common goal across genders today. Beyond this shared starting point, the psychological pathways connecting media exposure to risky behaviors diverged.
For women, the path from social pressure to harmful habits involved multiple interconnected steps. Both social media and peer interactions strongly predicted how often women compared their bodies to others. These comparisons, along with an internalized desire to be fit, regularly predicted higher levels of body dissatisfaction. As women became less satisfied with their own bodies, they were increasingly likely to report disordered eating routines geared toward building muscle.
Interpersonal dynamics played a uniquely visible role among the women in the study. Peer pressure not only fostered body dissatisfaction through external comparisons, but it also directly predicted muscle-focused disordered eating. When women felt appearance-related pressure from friends or acquaintances, they were highly likely to engage in strict aesthetic diets. This suggests that women experience intense scrutiny regarding fitness goals within their immediate social networks.
The statistical model for men painted a distinct picture. Just like the women, the men felt pressure from internet platforms, which led them to absorb the lean and muscular standard. But unlike the women, this internal drive predicted compulsive exercise and disordered eating directly, skipping the intermediate step of body dissatisfaction. For the male participants, simply feeling the need to achieve the ideal was heavily linked to obsessive behaviors, regardless of how they currently felt about their own bodies.
On top of that, interpersonal dynamics did not appear to dictate men’s behavior in the same way. The statistical paths connecting peer pressure to body image concerns and risky eating habits were notably weak in the male group. Broad cultural messaging on the internet seemed to act as the primary driver of extreme fitness habits for these men.
The researchers highlighted a few limitations in their work. Because the data was collected at a single point in time, the study cannot definitively prove that one psychological factor causes changes in another. The participant pool was also relatively small, predominantly female, and consisted mostly of college students of European descent. The authors recommended that future studies include more diverse groups to see if these patterns hold across different demographic backgrounds.
Additionally, the sample was restricted to individuals who identified strictly within the binary categories of man or woman. This restriction means the findings do not capture the experiences of non-binary, genderqueer, or genderfluid individuals. Those outside the traditional gender binary often face unique societal pressures regarding body image, making it an area ripe for expanded research.
Ultimately, this research indicates that the modern athletic aesthetic is not a neutral or universally healthy concept. While the standard looks identical for everyone on the surface, public health initiatives may need to address it differently depending on the audience. Programs designed to help women might need to focus on navigating social comparisons and peer groups. Conversely, education directed at men might see more success by directly addressing how digital media content alters individual aspirations.
