BAT contributes minimally to cold-induced thermogenesis in healthy adults; leaves open its therapeutic relevance in metabolic disease.
Does acute cold exposure increase brown adipose tissue oxygen consumption and energy expenditure compared to room temperature in healthy subjects?
In healthy humans, brown adipose tissue is only a minor contributor to cold-induced thermogenesis, whereas deep cervico-thoracic muscles play a major role.
U-Din et al. (2016) studied this question.
