Brown fat is intended to burn calories to produce heat. It is the reason why brown fat is commonly known as the “good” fat. Other than storing calories, the brown fat helps to burn. Brown fat comes from muscle tissue and found mostly in newborns and hibernating animals. As kids grow older, the amount of brown fat decreases considerably. Adults with comparatively more brown fat are usually younger and slim. They also have normal blood sugar levels.
Brown fat is generated when you exercise. Your body converts white-yellow fat to brown fat which is more metabolically active. Getting adequate high-quality sleep every night also generates brown fat. This is because an increase in melatonin production promotes the production of brown fat. Exposing your body to the cold, like when working out in cold weather, sponsors the production of brown fat. Consider lowering the temperature in your working spaces or living room.

That means if you have 20 pounds, you have 80,000 calories of energy storage. Your body usually requires about 2,000 calories per day for your survival. 20 pounds of stored fat in the body can help you to survive for 40 days without taking calories. Although these figures are not accurate, they are meant to give a general idea.
Generally, your body generates white fat when you consume many calories and spending fewer calories.
