If only we could lose weight as easy as we do our keys and passwords!

Anyway, experts say it’s all possible through exercise, dieting, and maybe a good supplement to spark it all up.

Weight loss supplements are especially becoming more popular every day and each product promises all sorts of unique, sometimes even rapid results.

In this review, we dig into Skinny Fiber, a weight loss supplement for women.

How does it work and is it legit? Let’s find out.

What Is Skinny Fiber?

As the name suggests, skinny fiber is a supplement that promises women weight loss results.

It is one of several products manufactured by Skinny Body Care, a company that specializes in weight management and wellness products.

Skinny fiber claims to promote weight loss by slowing digestion, causing satiety to last longer, decreasing hunger pangs, and promoting less feeding.

What’s more, they say only 100% pure, all-natural ingredients go into this product.

Glucomannan has been shown to expand tremendously in the stomach and intestines by absorbing water and forming a bulky fiber. Among its uses includes treating constipation, reducing cholesterol, lowering blood pressure, reducing blood sugar levels, obesity, and rapid gastric emptying. However, there is little research to support these uses and the existing studies don’t agree.
Caralluma Fimbriata
This succulent plant is part of the cactus family and has been used in ayurvedic medicine to suppress appetite as well as enhance endurance for centuries. It is believed to block specific enzyme activities that in turn prevent fat formation, forcing the body to metabolize fat reserves. C. Fimbriata is also thought to interact with the appetite control mechanism of the brain. However, there is no sufficient scientific evidence to back these claims and the only fact that current studies seem to agree on is that the plant is generally safe.
Cha De Bugre
Native to Brazil as well as the tropical forests of Argentina and Paraguay, Cha De Bugre is popularly used in Brazil for weight loss. It is also used for the treatment of cellulite, gout, cough, heart and blood vessel issues, viral infections, herpes, and cough, among others. Like the other two ingredients, however, we still don’t have enough evidence to support any medical uses of Cha de Bugre.
Other ingredients
Protease powder, Amylase powder, Lipase powder, Glucoamylase powder, Papain powder, Cellulase powder, Bromelain powder, Gelatin capsule, Microcrystalline cellusose, Magnesium stearate.

How Does Skinny Fiber Work

According to its suppliers, advertisements, and ingredients list provided, skinny fiber aims to aid in weight loss by increasing feelings of satiety through its core ingredient – glucomannan.

Glucomannan is a fiber that absorbs plenty of water to expand and fill the stomach, thereby reducing the urge to eat much or snack between meals.

This supplement could also aid in weight loss by suppressing appetite through the ingredient Caralluma Fimbriata.

Moreover, the antioxidants and digestive enzymes in skinny fiber may support digestive health and boost immune function.

These modes of action are purely based on the ingredients list and their available research as well as known uses in traditional medicine. The company itself does not provide much information concerning how Skinny Fiber works.

How To Use It?

skinny fiber supplement

You should take two pills of Skinny Fiber twice a day, at least 30 minutes before lunch and dinner, or any two big meals.

Each should be accompanied by a large glass of fluid and at least 8 glasses of water a day because the fiber needs to absorb moisture to expand in the stomach.

Drinking a lot of water may also help prevent digestive problems such as constipation and bloating.

Users are advised against taking more than 4 pills in a single day.

You may also open the pill and mix its contents with water or sugar-free juice in case you experience difficulty swallowing pills.

Are There Any Side Effects?

While the manufacturer reports no adverse reactions from skinny fiber, some users have experienced side effects including

  • Gas
  • Bloating (feeling too puffed up)
  • Boosted excretion
  • Constipation
  • Diarrhea
  • Nausea

However, these side effects are mostly natural and are expected to wear off as the pills clear the body.

Individuals suffering from low blood sugar are advised against taking Skinny Fiber as it may decrease glucose absorption.

Also, you should see a doctor immediately if you experience chest pain, difficulty in swallowing, or breathing problems after taking the product.

The above risk is more significant if the pill is swallowed with inadequate fluid, causing it to swell and block the throat and esophagus.

Is Skinny Fiber A Scam?

First of all, the manufacturer chooses words very cautiously in their claims, making no guarantees and leaving no legal loopholes.

That being said, the core ingredients used in Skinny Fiber seem to be part of traditional medicine in various cultures around the world for a long time now, which could imply they work.

Other than that, a few studies are surrounding some of Skinny Fiber’s ingredients but there’s no concrete scientific proof that taking it will result in weight loss.

Researches surrounding the supplement’s ingredients don’t seem to agree that they affect body weight.

For instance, one study 1 found that glucomannan may help reduce body weight but not body mass index while another found that it had no effect 2 on weight loss when the participants maintained self-selected diets and normal physical activities.

As far as approval goes, Skinny fiber is not accredited by the Better Business Bureau (BBB), which mostly concerns their customer service but might also reflect on product quality.

Their marketing is most aggressive on social media where they recruit advocates, creating a sort of multi-level marketing after-sales system.

Bottom line, the pills may promote weight loss when combined with dieting and exercise but there is no sufficient evidence to guarantee that they work on their own.

Really like it so far. Been trying for about two months now and lost 6 lb without working out. I don’t take it as directed on the package. I just take one in the morning another one in the afternoon and before dinner with a bottle of water each time. Really helps my cravings. If I get hungry I eat, then I will just stop eating cause I’m full. I don’t overeat or snack on trends as I use too.

I lost 80 pounds and 6 pants sizes. Skinny Fiber, portion control, and exercise. I still love this product!!

Chelsea reports:

This product was awful! I used it for about a week and when I wasn’t severely constipated and bloating, I had diarrhea and bloating. I finally stopped taking it when I woke up in the middle of the night super nauseous and continued to be nauseous for 24 hours.

Skinny Fiber Review: Should You Buy It?

Anyone selling these pills as a weight-loss panacea is hands down a fraud.

However, for those in search of supplements to help them eat less and still feel full so that they can attain their diet goals, Skinny Fiber is not such a bad idea.
