How Prime Science can help you

At Prime Science, we know you are the kind of people who want to be fit and healthy. In order to be that way, you need to be very disciplined with what you eat.

The problem is this means sticking to super strict diets making you feel you can’t eat anything tasty as well as long exhausting exercise routines making you feel you spend all your time exercising.

We believe it is ridiculous that this should be the case with all that researchers know about the human body today. We understand that it is hard to stick to strict diets and long time-consuming, exhausting exercise routines. That’s why we have created the Prime Science Calorie Burner Vest and Fat Freezing
. These make you able to burn calories and fat while you are watching tv on the sofa or a conference call. This saves you both time and effort.

Frequently Asked Questions

I couldn't find the answer to my question

Please send us an email here or email us on

What happens if it doesn't work for me?

Prime Science give a full 90-day money-back guarantee. Just send it back, and we will refund you your purchase.

I think it's expensive

It’s a one-time purchase that you can continue to use. You can also share it within your household. Compare it to a gym membership or something similar that cost every month, and you can't share, it's really affordable.

Will it be very cold?

You will start on a lower cold level for both products and gradually build up when comfortable. This makes it possible for anyone to use the products even if you don’t like or are used to cold.

How do I use it?

Both products are very easy to use. You will receive a guide on using the vest and the belt. For any questions, you can also contact us at

What happens if any of the ice packs breaks?

The content in the ice packs is completely toxic free. If an ice pack breaks just email us on and we will send you replacement packs free of charge

Are there any side effects?

You might experience some of these temporary side effects: redness
and tingling, and numbing feeling on the treated area(s). This is entirely normal and generally resolves within 15 minutes after the treatment has ended

Is it painful?

No, it's not painful. It can feel cold and tingling in the beginning. This feeling does subside after a short while.

Are the products safe?

Yes, they are safe when used as directed. Our ice packs have gone through extensive testing with the Calorie Burner vest and Fat Freezing belt to ensure they are safe to use.

Will it work for my body type?

The extensive research our products are based on covers most body types

The Fat Freezing Belts works best for people who are not far from their ideal body weight (within 25%). If you have a lot of weight to lose, we recommend using the Calorie Burner Vest until you come within 25% of your ideal body weight. Then use the Fat Freezing belt to help you through “the last mile” in your journey while also using the Calorie Burner Vest.

What is brown fat?

How quickly will I see results?

It depends on how often you use the products.

Fat Freezing Belt: if used 3 times per week as directed, results can come as early as 3 weeks. For some, the results take longer

Calorie Burner Vest: It highly depends on the usage level. The more usage, the faster the results. If used 1-2 hours at medium to high intensity, you can see weight loss after around 4 weeks. If you use it less, it is expected to take longer. As it is calorie-burning, this is consistent with starting a diet or an exercise programme, but with significantly less effort.

How do I wear it?

The Fat Freezing Belt is worn straight towards the skin on the target area

The Calorie Burner Vest is worn with a thin layer like a t-shirt between the vest and the skin
