Female adults have a significantly higher prevalence of brown adipose tissue (BAT) activity compared to male adults.

Women are more likely to have active brown fat than men. This biological difference may contribute to variations in metabolic rate and fat handling between sexes. It does not mean men cannot benefit from BAT activation, but the baseline prevalence is lower.

BAT was also more common in female patients (female: n = 107, 7.2%; male: n = 60, 2.8%; P < 0.00001...)
