A scientific study has found that men who feel financially insecure or hungry are more likely to find larger female breasts attractive.

The research was published in the peer-reviewed journal PLOS ONE and was conducted by psychologists Viren Swami and Martin J. Tovée.

The study examined whether breast size acts as a signal of fat reserves and access to resources, and whether men facing resource insecurity rate larger breast sizes as more attractive than men who feel economically secure.

Researchers carried out two separate studies across Malaysia and the United Kingdom.

In the first study, 266 men from three areas in Malaysia were assessed. The locations represented low, medium and high socioeconomic backgrounds. Participants were shown rotating computer-generated images of women with different breast sizes and asked to rate which they found most attractive.

The findings showed a clear socioeconomic pattern.

Men from low-income rural areas preferred larger breasts.

Men from middle-income towns preferred medium to large breasts.

Men from high-income urban areas preferred smaller to medium breasts.

As stated in the study, “Men from relatively low socioeconomic sites rated larger breast sizes as more physically attractive than did participants in moderate socioeconomic sites, who in turn rated larger breast sizes as more attractive than individuals in a high socioeconomic site.”

The researchers noted that the lower a man’s financial security, the stronger his preference for larger breast size.

The second study focused on hunger rather than income.

In Britain, 124 male university students were divided into two groups. Sixty-six participants were classified as hungry, while 58 had recently eaten. Both groups viewed the same breast size images under identical conditions.

Hungry men consistently rated larger breasts as more attractive than men who were full.

According to the researchers, “Hungry men rated a significantly larger breast size as more physically attractive than did the satiated group. Taken together, these studies provide evidence that resource security impacts upon men’s attractiveness ratings based on women’s breast size.”

The researchers explained that these shifts suggest attraction is not fixed but responsive to immediate conditions.

They noted that men experiencing hunger or financial pressure may place greater value on physical traits that signal access to resources or stability.

The study added that temporary states such as hunger can shape attraction in the same way long-term economic conditions do, reinforcing the idea that social and environmental factors play a key role in how physical attractiveness is judged.
