Cold wearables may trim fat: study finds modest weight loss with ice-vest use

In a six-week study of 47 adults with overweight/obesity, wearing an ice vest and waist wrap for two hours each morning led to a 0.9 kg loss of fat (while controls gained 0.6 kg), suggesting cold exposure activates brown fat and could aid weight loss alongside diet and exercise; researchers are also testing whether cold showers yield similar results, noting differences like cold shock between methods.
