Energy balance

Activation of metabolically active brown adipose tissue (BAT) in adult humans increases energy expenditure via UCP1-mediated thermogenesis, thereby counteracting weight gain and obesity.

You likely have metabolically active brown fat, even if you are an adult. This tissue burns energy as heat, helping to regulate your weight. While you cannot 'buy' brown fat, keeping your living environment moderately cool (cold exposure) may stimulate it. However, be aware that BAT activity decreases with age and higher body weight, which may contribute to weight gain over time. It is not a magic bullet, but a biological lever you can influence.

GoodSupportsHIGH confidence
BAT dissipates energy as heat and can thus counteract weight gain. Interindividual variability in the amount or function of this tissue may impact body weight. In addition, therapeutic expansion/activation of this tissue may prove to be an effective therapy for obesity.

Why this rating

Based on recent human studies (PET/CT, biopsies) confirming functional BAT in adults, though it is a commentary summarizing these findings rather than a primary clinical trial.
