Skinny Fiber, a glucomannan-based supplement, claims to suppress your appetite, reduce cravings, and aid in weight loss without necessarily changing your diet. Now that’s an audacious claim, but what caught my attention is the negative reviews from its customers. Most people have complained about the ineffectiveness of the supplements and their customer service. Why the numerous negative reviews? Could it be Skinny Fiber is fake or a scam? Well, let’s find out.  

1. What Is It: A Closer Look at Skinny Fiber

Skinny fiber

Skinny Fiber, an appetite suppressant.

Skinny Fiber is a fiber supplement formulated with glucomannan, a bulk-forming fiber. According to research, glucomannan can slow down stomach emptying and reduce protein and fat absorption. It is also believed that the fiber can also suppress your appetite and hunger pangs.

2. History of the Brand

Skinny Body Care, launched in 2011, is behind Skinny Fiber and other lifestyle products. It is an MLM company that markets and sells its products through its distributors.


Phone Number: (855) 437-4638

Company address: Windermere, Florida 34786

3. Ingredients Used

Skinny Fiber contains a variety of herbal extracts and enzymes formulated to decrease belly fat and overall weight.

Proprietary Herbal Blend

Skinny Fiber supplements contain 1,160 mg of three natural herbs.

  • Glucomannan

Skinny fiber glucomannan

Glucomannan is the active ingredient in Skinny Fiber.

This water-soluble fermentable dietary fiber is extracted from the konjac yam and it contains compounds that prevent it from being digested. Glucomannan is a bulk-forming fiber, meaning it absorbs water up to 50 times its weight, and that’s why glucomannan is taken in small doses.

This viscous fiber has a low energy density that allows it to displace other nutrients and promote satiety. Furthermore, it delays stomach emptying and helps to lower, total cholesterol, LDL cholesterol, and triglycerides [1, 2, 3].

Does glucomannan aid in Weight loss?

Although glucomannan is classified as a weight loss dietary supplement, it’s been discovered that the fiber does not produce any long-term weight results on its own.

What’s interesting, Skinny Body Care claims its supplement can aid in weight loss without diet modification. However, according to research, glucomannan is not effective without a proper diet and exercise regimen. Keep in mind that your body composition will affect how well glucomannan works [4].


The accepted dosage of glucomannan is 1- 3 grams a day [5]. However, a clinical study indicated that a 3.9 g/day dosage did not aid in long-term weight loss [4].

Additionally, Skinny Fiber does not indicate the glucomannan dosage used, so it’s hard to determine if it works or not.

Other benefits

Glucomannan also promotes bowel movement and increases probiotics like lactobacilli and bifidobacteria that enhance the gut health [6].

  • Caralluma Fimbriata

Skinny Fiber contains the whole plant of Caralluma Fimbriata. Before it gets technical, Caralluma is an edible cactus that is found in India, Africa, and the Middle East. The cactus has a foul smell and is normally boiled before use. In India, the plant is used to decrease appetite [7].

When it comes to research, there have been inconsistent findings. One 2-month study discovered that Caralluma Fimbriata could suppress appetite and reduce waist circumference [8].

However, a 12-week clinical study reported that C.Fimbriata did not aid in any significant weight loss after the trial period. Furthermore, the subjects did not experience a decrease in appetite or hunger suppression [9].

In both of these studies, the subjects were given 1g/day of  C. Fimbriata. The inconsistency in the clinical trial makes it difficult to ascertain if Caralluma Fimbriata aids in any significant results.  

  • Cha de Bugre

Skinny Fiber contains Cha de Bugre leaf obtained from a tree known by the same name. According to WebMD, Cha de Bugre, found in Brazil, works by suppressing appetite.  However, I couldn’t find any research to support Skinny Fiber claims that the herb helps in weight loss.

Enzyme Blend

Skinny Fiber contains 360 mg of digestive enzyme powder including amylase, protease, lipase, and papain among others. According to Healthline digestive enzymes help to support body functions, and a decline in the levels will affect the digestion, absorption of foods, and overall health.

Skinny Fiber comes with these enzymes that help to share the digestion burden of your naturally occurring enzymes.

4. How It Works

According to its website, Skinny Fiber works by suppressing hunger, providing satiety, and enhancing the digestion process through its enzyme blend.

5. Benefits and Results

The ingredients used in Skinny Fiber offer great benefits:

  • The supplements delay stomach emptying which provides satiety and reduce calorie consumption
  • It helps to lower cholesterol levels
  • Skinny Fiber enhances gut health and promotes a healthy digestive system.

6. Does it Work?

Skinny fiber does it work?

Glucomannan works as an appetite suppressant, but not as a weight loss supplement.

Skinny Fiber has received mixed reviews, some claiming it is aids in weight loss. However, from the ingredients and the research available, the supplements do not aid in any measurable weight loss.  Its active ingredient, glucomannan has proven to be ineffective in weight loss.

7. Directions

Take two capsules of Skinny Fiber with 8 Oz water, 30 minutes before breakfast or lunch (two of your largest meals)

8. Precautions and warnings

As aforementioned, glucomannan is a bulk-forming fiber, meaning you need to take a significant amount of water to avoid choking. Moreover, it absorbs water available in the digestive tract and can cause dehydration and constipation.

9. Will it work with your diet?

Skinny Fiber, like most weight loss supplements, can work great with low-calorie, low-carb, or high-fiber diets.

10. As Far as Taste Goes

These are capsules, so the taste doesn’t apply here.

11. Potential Side Effects

Although Skinny Fiber website doesn’t mention any side effects, the ingredients used can have negative effects:

  • Choking
  • Diarrhea,
  • Bloating
  • Flatulence
  • Nausea
  • Constipation

12. Lawsuits

Currently, there is no lawsuit against Skinny Fiber. However, there have been numerous complaints against Ben Glinsky, the C.E.O of Skinny Body Care. Most users have complained that their login details had been changed previously without their consent, and therefore they can’t access their earnings (Skinny Body Care is an MLM).

13. Cost

Skinny Fiber costs around $59.95on Amazon, and it’s currently not in stock. You can also buy via the website, but you need to have a name of the distributor who referred you.

14. Alternatives

A variety of fiber supplements are at your disposal; however, two of them have proven to be great competitors.

Unlike Skinny Fiber, Benefiber is formulated with wheat dextrin, a water-soluble fiber. Wheat dextrin is effective in reducing blood glucose, increases nutrient absorption, and prevents gastrointestinal disorders.

  • Metamucil

These fiber supplements contain psyllium husk that has proven to be effective in suppressing appetite.

15. Other products

Besides the fiber supplements, Skinny Body Care offers a range of life-changing products:

  • P4 Protein Shake a meal replacement shake formulated with three different types of protein to help in weight loss.
  • Skinny Body Max
  • HiBurn8
  • E3
  • Instant youth
  • Ageless

15. What Customers Are Saying

Skinny Fiber has received a mixed of reviews, with most customers indicating that it does not work.

“Since I started using Skinny Fiber, I have not noticed any change, apart from the frequent visits to the bathroom (You have to take a lot of water with these supplements.”

Livette Sims

“ Skinny Fiber didn’t work for me. I was told to use for three months before I could see any significant results, and 3 months down the line, I have not seen any results.”


However, some customers have expressed optimism with these supplements:

“I have used Skinny Fiber for six months and lost 40 lbs. For these supplements to work, you must follow the instructions given.”

  1. Bills

“These supplements have helped me with my cravings. I haven’t lost weight yet, but I have more energy when working out.”


16. Final Verdict

Would I recommend Skinny Fiber? No. Not because it has 2.8 rating on Amazon, or that it has mostly negative reviews (which is alarming), but because of:

  • Glucomannan, the active ingredient, doesn’t seem to have any effect in weight loss. According to research, the acceptable dosage of this bulk-forming fiber is 1-3 grams per day, which has shown to be ineffective.
  • Skinny Fiber doesn’t indicate the dosage of the ingredients, so we can’t tell if the amount used is above or below the recommended dosage.
  • There have been numerous complaints from its users about their bad customer service.

Instead of using Skinny Fiber, try changing your diet–a healthy diet and moderate workout is the best way. You can also opt for intermittent fasting which has proven to be effective in regulating blood sugar and aid in weight loss.

You can buy Skinny Fiber from Amazon or official website.
