People have traditionally relied on diets and workouts to get in shape, but now there's a better option: Brown fat!

When you're looking to lose weight, there's no question that exercise helps. However, there's another fat-burning option that can help you burn calories and keep weight off, one that you didn't even know you had. In fact, brown fat can help you burn loads of calories every day —even when you're sleeping! Learn the best ways to activate brown fat, and start increasing your calorie burn.

In this blog post, you will learn what brown fat is, how it can help you burn a lot of calories and fat and how you can get more of it. So, if you don't want to miss out on this, continue reading. 


What is brown fat? Is brown fat good or bad?

The medical community didn't think that adult humans had brown fat until around 20 years ago. What happened was that they saw highly metabolically active tissue on CET/PET scans when looking for cancer on some patients around the upper back and collar bone area. What they initially thought was cancer turned out to be active brown fat. After this discovery, they have that it is a highly metabolic tissue.  

Brown fat acts like the body's thermostat and keeps us warm. When the brown fat is activated to keep us warm, it burns a lot of energy in the form of calories. This makes brown fat an exciting target for weight loss! 

As brown fat keeps us warm and burns a lot of calories, it is perfect to have as much brown fat as possible. 

Why is brown fat brown?

Brown fat, in difference from white fat, contains a lot of iron-dense mitochondria. The iron in the mitochondria gives the brown fat its brown colour. 

Can brown fat cause weight loss?

The simple answer is YES! All weight loss is based on the simple energy equation calories in minus calories out. Having a lot of active brown fat will increase the calories you burn, which heavily increases the calorie out part of the equation brown fat can lead to very substantial weight loss. 

How does brown fat burn calories?

As mentioned, brown fat acts like the body's thermostat to keep us warm. What the brown fat does is that it works much more like a muscle, but instead of generating force and heat, it only generates heat. For a muscle to generate heat, it needs to move. However, brown fat can create heat without any movement. It takes energy from other fat cells and what we have eaten when it creates that heat. 

When you have brown fat and activate it, it will increase your calorie burn even when resting. It will help you burn more calories in the long run and help you keep the weight off when it's lost. 

How can you get more brown fat?

The best way to generate more brown fat is to expose yourself to cold. The exposure can be through cold showers, baths, or just wearing fewer clothes when it's cold outside. You also turn down your temperature inside. All these methods have also been shown to increase your brown fat in the long run.

It's important to know that it will be a bit uncomfortable if you are cold at first. However, your body will quickly adapt to the cold and generate more brown fat to stay warm.  

In a later blog post, we will go into more in detail on how you can get more of this fantastic calorie-burning fat! 


Brown fat acts like the body's thermostat to keep you warm. While it keeps you warm, it uses calories to help you get a calorie deficit leading to weight loss. It will also help you maintain a higher calorie burn to keep the weight off. The best way to get more brown fat is to expose yourself to cold in any form. 


To lose weight and fat most people do hours of exercise and stick to strict diets. Prime Science has created a Fat Burner Vest and Fat Freezing Belt that burns a lot of calories and freezes away fat without moving or exercising. This makes you lose weight and fat to achieve the body you always wanted while getting hours back and enjoying the food you love.
