Skinny Fiber bad reviews, what are the customers saying?

Skinny Fiber Claims

Skinny Fiber is a natural prescription-free diet pill produced in the United States. Its active ingredients are two natural dietary fibers, Glucomannan and Caralluma, which are designed to expand in the stomach to provide a feeling of fullness, sounds great but what about the Skinny Fiber bad reviews – what are customers saying?


Skinny fiber ingredients – do the claims stack up?

The product is marketed as an appetite suppressant rather than a fat blocker or fat burner. Skinny Fiber consists of three main ingredients: glucomannan, carallum and Chá de Bugre. The supplement claims to work by using these natural plant extracts which are difficult to digest by the body. As the fibers passes through your system, they collect water, swell, and add bulk.

Clinical trials on glucomannan, which derives from the Asian Konjac plant, have proved inconclusive for weight loss. Other studies suggest that reduced fat absorption from the small intestine does not lead to overall weight loss (see for example

The other ingredient claimed by the manufacturer to be a natural appetite suppressant is Caralluma; a cactus which is native to India. There is scientific support for this claim from a clinical study ( conducted by the University of Bangalore, which found that 50 obese participants reduced both weight and waist size by taking Caralluma for two months.

Chá de BugreChá de Bugre
The third ingredient, Chá de Bugre, derives from the fruit of a Brazilian tree. Resembling the coffee bean, the fruit is typically used as a substitute for coffee. Although it is free from caffeine, Chá de Bugre is a potent stimulant. The main concern with this ingredient is that its export is prohibited by the Brazilian government, hence it is uncertain that genuine Chá de Bugre is actually included in this product.


  • Unlike the vast majority of diet supplements, Skinny Fiber contains zero caffeine and may therefore be attractive to those who suffer from caffeine related insomnia, headache and anxiety.
  • There are a number of positive customer reviews, although given the company’s system of marketing through a host of distributers, it is not clear which are genuine customer reviews.  On Amazon, the product achieves marginally above 2 stars.
  • The company offers a money back guarantee.


  • The website is very poor, making claims for the product which are unsubstantiated by any scientific evidence.
  • The quantity of glucomannan contained in this product may be insufficient to be effective as an appetite suppressant.
  • The marketing of the product is very dubious, with the manufacturer offering an auto-shipping option which may prove difficult to cancel. These are notorious in the diet pill industry and are used to lock customers into receiving the product each and every month.
  • Even with special offers such as ‘Buy two, get one free’, this diet pill is expensive.

Potential Side effects

Glucomannan has been associated with a risk of choking, and customers are advised to take plenty of water with this product to reduce the risk. Increased bowel movements are likely, because of the fiber content, and some customers report diarrhoea, nausea and discomfort in the stomach.

Skinny Fiber review conclusion

Overall, Skinny Fiber is a product which makes many claims. Because of the company’s marketing strategy, it is available from a host of distributers, but it is both expensive and unproven.

Until the company backs up its extravagant claims with scientific research, this is probably a product which is best avoided.
