Fat Fighter – Reduces Calories from Fat

Fat-Blocking Formula – For the Treatment of Overweight

Fat Fighter is a scientifically documented formula that helps reduce calorie intake from dietary fat.

✔ A revolutionary and patented formula consisting of Chitosan derived from fungi (Aspergillus niger) and white kidney bean extract (Phaseolamin).

The active ingredients are Chitosan and white kidney beans.
Chitosan is a natural fibre with a high ability to bind lipids. It helps neutralise calories from high-fat foods. In the stomach, it forms a gel-like substance that mixes with the food.

At the same time, white kidney bean extract inhibits the starch-digesting enzyme alpha-amylase from the pancreas. This interrupts the carbohydrate digestion process.

Because balance starts from within – with Fat Fighter!

Your questions answered

What does it mean for a product to be a medical device?

Medical devices are products intended to prevent, alleviate or treat a condition. In the UK they are regulated by the MHRA and must carry a UKCA or CE marking. Always read the enclosed leaflet, which tells you how long you can use the product.

How long does one pack last?

It depends on the product and dosage – see the How to use section and the enclosed leaflet. For Calorie Fighter and Fat Fighter, one pack of 30 tablets lasts 5 days at the recommended dose of 2 tablets 3 times a day.

Can I combine a medical device with other Slim Boost products?

Yes, but don't use Calorie Fighter and Fat Fighter with the same meal, and always follow the directions and limitations in the leaflet for each product. If you take medication, talk to your doctor before use.
