How Brown Fat (also called Brown Adipose Tissue or BAT) and cold thermogenesis help you lose weight

The science behind it all

Brown Fat is primarily found around your collar bones and upper back. Brown Fat is an entirely unique type of fat that can generate heat by burning the regular white fat found on your stomach, hips and rest of your body. When you exercise, you first need to burn through what you have eaten. However, Brown Fat is different. It can immediately and directly burn white fat. It's simply put a fat-burning machine.

Studies show that people with activated Brown Fat burn up to 15% more calories 24/7. That makes a massive difference over time. One study has also demonstrated that constitutionally lean women have active Brown Fat. How would it feel to be one of those who cannot gain weight? 

By wearing the Calorie Burner Vest, you expose yourself to the type of cold that has proven to activate your Brown Fat and start burning calories and fat. When you activate your Brown Fat, you also expose yourself to cold thermogenesis, further increasing your calorie burn.

It's that simple!

Scientific studies showing the impact of Brown Fat

The impact of BAT has been shown in multiple scientific peer-reviewed studies:

How can we help?


What is Cold Thermogenesis?

Cold Thermogenesis is a fairly new and very promising area
in fitness and weight loss. Simply put it’s the use of cold treatments to
improve your physical and mental health and body composition.

There is a range of benefits:

How much calories can I burn?

In the same way as exercise, the number of calories you can burn and, therefore, how much weight you can lose with the Calorie Burner Vest is dependent on the intensity level how often you use it. At the highest intensity level, we have increased the calorie burn by 200% for an extended amount of time.

Your body will gradually adapt to the cold and then burn more calories as a result

Low intensity (suitable for beginners)

How it feels: you will feel lightly cooled down

You can use this for several hours each day, every day of the week

We typically see a 20-30% increase in calorie burn at this intensity level


Medium intensity:

How it feels: It feels chilly, and you likely have goosebumps

You can do this for a few hours each day, every day of the week

We typically see a 30-50% increase in calorie burn at this intensity level 

High intensity:

How it feels: you are at pre-shivering levels up to full out shivering

You can do this for a few hours every day of the week

We have tested the Calorie Burner Vest in a lab and reached a 200% increase in calorie burn while sitting in a chair at this intensity level

Where do I lose fat when using the Calorie Burner Vest?

You will lose fat all over your body in the same way as with diet and exercise. The Calorie Burner Vest does not remove fat specifically at one spot. It helps you lose weight by creating a calorie deficit.

How is it different than just sitting in a cold room?

You can definitely achieve some advantages of wearing the Calorie Burner Vest by sitting in a cold room. The room will have to be at most 15-17 degrees to get close to the intensity level you can achieve with the Calorie Burner Vest.

A huge benefit of using the Vest is that it can be used all year round regardless of outdoor temperature. During the summer months, you will struggle to reach the indoor temperatures required to impact your calorie burn significantly. If you open up windows etc., to bring down the temperature indoors during the winter, it might take a lot of energy to warm up the house or room again after your cold session. This will likely become expensive in the long run.
