This study explores somatotype-based differences in body image awareness among 18–23-year-old Mesomorphs, Ectomorphs, and Endomorphs from Mysore University-affiliated colleges in Karnataka, India. Stratified sampling chose 150 male college students to test body image awareness using the Body Self-Image Questionnaire (Short Form). The three somatotype groups had significantly different body image awareness scores. Endomorphs had the most body image awareness, followed by Ectomorphs and Mesomorphs. After descriptive data, Mesomorphs had the lowest mean body image ratings (85.52) and Endomorphs the highest (98.98). A one-way ANOVA showed significant differences across groups (F = 111.31, p < 0.001). Tukey's HSD test post-hoc analysis showed significant pairwise differences, with Endomorphs scoring higher than Ectomorphs and Mesomorphs and Mesomorphs scoring lower than Ectomorphs. These findings imply that societal and cultural body type beliefs affect body image awareness as well as physical appearance. The findings emphasize the need of somatotype-specific body image therapies for young adults' body satisfaction and mental health.
