WAT is primarily linked to fat storage and obesity, while BAT is crucial for thermogenesis. WAT cells store energy and secrete hormones like leptin, expanding in size with obesity. Exercise might convert WAT to "beige" cells, which have BAT-like features. However, obese individuals tend to have fewer beige cells due to the insulating effects of excess WAT.
