Interestingly, researchers now think that exercise could be a shivering mimic as there is muscle contraction in both processes and exercise-stimulated irisin could have evolved from shivering in the cold.

“Excitement in the brown fat field has risen significantly over the past few years because its energy-burning nature makes it a potential therapeutic target against

Earlier, scientists believed that brown fat would disappear after early infancy, but the notion has now changed. It has been found that most adults carry brown fat and the more you have, the slimmer you are likely to stay.
