Energy balance

Cold exposure induces non-shivering thermogenesis via brown adipose tissue (BAT) and beige adipocytes, increasing energy expenditure by 2-17%.

Exposing your body to cold temperatures can activate brown fat and increase calorie burning. Start with small, manageable exposures like slightly cooler showers or a lower bedroom temperature. Consistency is key to building up your body's thermogenic capacity.

extended periods of cold exposure will lead to a sustained higher metabolic rate with reports of increased energy expenditure ranging from 2 to 17% including elevations in both SMR and TEF

Why this rating

The paper reviews studies showing increased energy expenditure, but notes that the extent of BAT activation varies and is a genetically predisposed phenotype.
