Energy-burning brown fat less active in boys with obesity. Researchers performed MRI scans to measure BAT activity in 26 boys between the ages of eight and 10. They studied the BAT tissue in the neck before and after one hour of exposure to a cold suit set at a temperature of 18 degrees Celsius. The patient sample included 13 boys with a normal BMI and the same number again with obesity, in the first study of its kind in children. Source 3m.
