There is a significant focus on activating brown fat in healthcare communities. For example, this review paper on Frontier’s Physiology journal mentions that “activation of brown adipose tissue represents today a promising strategy to enhance energy expenditure through heat production. More recently, “browning” of white adipose tissue has gained increasing attention in the research area as an alternative method in stimulating energy dissipation.” I have been researching the topic for over a decade. Even though I gained insights from the literature, most of my knowledge was through my personal experimentation and observation of people with relatively more brown fat than others. So, without going into too many scientific details, I introduce three practical tips to increase brown fat with simple lifestyle habits by citing a few prominent papers.
