Give me two minutes of your time and I’ll tell you whether this one actually works. Not surprisingly, Skinny Fiber is all about using fiber to increase weight-loss. We were interested in how this supplement differed from a traditional fiber supplement so we did one of our 360-degree reviews, examining ingredients, side effects, clinical research and customer-service quality. Plus we read hundreds of user comments and reviews from around the web. We then summarized and condensed to give you the info you need.
What is Skinny Fiber?
First off, Skinny Fiber is a diet pill that is supposed to expand in the stomach to help you feel fuller  and eat less. The active ingredient is the water-soluble fiber glucomannan.  You take two capsules before lunch and dinner. One bottle contains 30 days worth of the product. You can take Skinny Fiber anywhere because pills are portable.
All of the ingredients in Skinny Fiber are natural. Many are found naturally in foods. The website offers the product and there are a few positive comments from dieters who’ve tried Skinny Fiber and lost weight. It should be noted this company was given an “F” by the Better Business Bureau. We like the idea behind trying fiber to suppress appetite, but read on…
I had to make sure there was a restroom near by after I ate.
Price – “A Consideration?”
The first thing we are concerned about is the price of Skinny Fiber. “It contains a good source of fiber,” says our Research Editor. “There is a chance you will feel fuller after taking the supplement. The problem is that fiber is widely available for less than $5 in most stores. At $39.90 a bottle, Skinny Fiber does not sell us on why this supplement is better than other fiber supplements  that cost much less.”
“Not only did this not help subside my hunger, it didn’t help me lose any weight,” according to one dieter.
Another dieter suggests the same thing. “This product doesn’t work. I tried it and it just made me feel off. I won’t try this again.”
If you can get passed the price, there are some positive comments. One buyer says, “Tried it, sporadically, and had less hunger.” 
Another positive experience claims, “The fiber does help with regularity if you need it.”

Other Concerns – “BBB, Customer Service & Headquarters”
We are concerned about the company’s poor BBB rating and lack of customer service support. We called the customer service department and were told that no representative could take our call. The recorded message suggested we send an email to the customer service department. Skinny Fiber’s Better Business Bureau rating is an “F”. Not a good sign.
Also, the Skinny Fiber headquarters is located smack dab in the middle of a shopping center. You can turn the corner to visit AT&T or a small bakery. We can’t imagine a research facility or anyone in lab coats testing ingredients and formulas. Without research, where are the product claims coming from?
Our experience reviewing weight-loss supplements has delivered one important fact. If the product is priced too high for what it is or the company is not professional, your chances of success with the supplement are typically not high. In addition to price, BBB, headquarters and customer service are potential issues for Skinny Fiber.
If you insist on using Skinny Fiber for weight loss, consider information from the Harvard Medical School. Taking 30 grams of fiber can help you lose weight, but Skinny Fiber contains less than 1.16 grams of fiber.
Skinny Fiber Science – “Real Evidence?”
Skinny Fiber does not offer research proving the supplement is more effective than common, widely available and inexpensive forms of fiber that supply amounts closer to that suggested by health professionals.  For us at DietSpotlight, it’s critical when reviewing a product to find scientific research indicating the supplement delivers results beyond those you’d experience with a much-cheaper alternative.

The Bottom Line – Does Skinny Fiber Work?
If you’re ready to buy this one, hold on one more minute. We are always interested in looking deeper into supplements like Skinny Fiber. We like that the company offers a supplement that can help you feel fuller, longer. However, we’re not fans of the fact Skinny Fiber is priced several times higher than common fiber supplements, yet delivers the same results, so we can’t help but be skeptical about recommending it. We also don’t like Skinny Fiber’s “F” rating with the BBB.
If you’re going to invest real money and time into a diet supplement, you may try one that delivers both bang for your back and excellent ingredients backed by published research.
Among the best products we’ve seen in 2016 is one called Leptigen. Its formula is a proprietary blend of four ingredients, which have been shown in published clinical research to help accelerate fat loss and boost metabolism. We can’t find any talk of any harmful side effects and comments around the web indicate people are seeing great results.
The makers of Leptigen are so confident in their product they’re offering a Special Trial Offer, which is a good sign.
Previous Skinny Fiber Review (Updated May 16, 2014):
Skinny Fiber - What You Should Know
Skinny Fiber, sold by Skinny Body Care, is a fiber supplement that expands in the stomach to reduce hunger. According to the supplement description, the fiber expands 50 times its normal size. In addition to reducing hunger, the supplement will boost metabolism and suppress the formation of fat. This sounds like a super supplement, but chances are the ingredient list will not support these extraordinary claims. The fiber rests in the belly and flushes it like Biocleanse
. Having the word "skinny" in a product name does in fact always gain some curiosity for people looking to achieve weight-loss. Similar "skinny" weight-loss products are Skinny Bunny Tea
which offers four different blends like Weight Loss PM and AM Teas, Detox Teas, and Energy Teas; and other products like Skinny Teatox
which is a laxative tea.
Skinny Fiber is not a supplement with special ingredients known only to the manufacturer. The three ingredients in the supplement are commonly used in other weight loss supplements. Glucomannan is a water-soluble fiber. It does absorb water and expand, but there needs to be enough water in the stomach for the fiber to absorb for it to expand 50 times. There is a button for dieters to learn more about how to take the supplement, but the button only leads to a “Coming Soon!” page. A similar product which also aids in weight loss, but has claims of constipation, is Smooth Move Tea
Caralluma Fimbriata is a cactus extract that reduces appetite. Sounds a lot like the Hoodia cactus, right? The supplement company claims Caralluma Fimbriata will stop hunger and block the formation of fat, but they don’t bother to back up these claims with clinical research. Just as the Caralluma inhibits hunger the Iodine in Iodine Plus 2
increases thyroid function, thus inhibiting hunger leading to weight control. There are clinical studies supporting the antiobesogenic effects of the ingredient, but only on the rat population. Human studies are not available.
The final ingredient is Cha de Bugre. Cha de Bugre is a Brazilian plant that contains caffeine. The caffeine levels are lower than other stimulant herbs, but the stimulating effects may be stronger than standard caffeine. The ingredient also contains acids known to improve healing.
The official website for Skinny Fiber leaves much to be desired. There is very little proven information on any of the ingredients and some of the pages are under construction. Unfortunately the company has an unsavory "F" BBB rating
. It's always disappointing to see popular brands with low ratings like Revlabs
. There are no testimonials for the supplement and before and after pictures of dieters losing weight on the supplement are nonexistent. The Skinny Fiber Side Effects
have us a bit concerned as well.
Skinny Fiber is sold through the official website, but the order page does not list a price. The consumer is told to enter shipping information, but no credit card information. The terms and conditions of the website list the price as $59.95. This is higher than products of similar formulation like Liporidex
at $40. There is a 100% money back guarantee for 30 days following the purchase.

We are all about limiting the risk of side effects when it comes to trying new weight loss products. One supplement we’ve been noticing in particular, Leptigen, has four-salient ingredients proven in studies to burn fat, boost energy levels and ignite the metabolism.
1. Nausea and Vomiting – Adults (2015). Medline Plus. October 6, 2016.
2. Diarrhea (2013). 2. National Institute of Diabetes and Digestive and Kidney Diseases. August 12, 2016.
Skinny Fiber is a fiber-based capsule that's supposed to help you feel full so you eat less. The official website claims the formula will also help "gently boost your metabolism", but there's no clinical research offered to support this. Despite the main ingredient being fiber, the label reads only 1g of carbohydrates (fiber is a carbohydrate).

We looked into the Skinny Fiber ingredients to give you the information you need.
Derived from the konjac plant, glucomannan is a sugar that can be found in powder, capsule, and tablet form. This dietary fiber is well known in the diet world as a “bulk-forming laxative”. The ingredient was popularized by Dr. Oz, who referred to glucomannan as, “’nature’s skinny sponge’ because it literally soaks up your hunger.”
What is it Supposed to Do?
As a dietary fiber, glucomannan is thought to work in the stomach and intestines. Used as a gelling agent, glucomannan absorbs water and slows the absorption of sugars. It can also improve blood cholesterol, LDL cholesterol, and triglycerides. In terms of weight-loss, glucomannan is thought to delay stomach emptying, which can slow down digestion of sugar and lower your blood sugar after every meal.
In a study performed by La Pediaria: Medica e Chirugica: Medical and Aurgical Pediatrics, “Excess weight and triglycerides levels were significantly decreased in treated obese patients than in obese controls 4 months after the beginning of the study.”
According to The American Journal of Clinical Nutrition, similar results were found. In the conclusion of their study, they found “Glucomannan appears to beneficially affect total cholesterol, LDL cholesterol, triglycerides, body weight, and FBG…” 
Compared to other fibrous ingredients that promise weight-loss, glucomannan still performs above the rest. In studies performed by the International Medical Journal of Experimental and Clinical Research, where glucomannan, guar gum, and alginate were tested, “Glucomannan induced body weight reduction in healthy overweight subjects, whereas the addition of guar gum and alginate did not seem to cause additional loss of weight.” 
When searching for weight-loss supplements that are truly effective and not gimmicks, search for clinically tested ingredients from a company that offers amazing results. Leptigen is one we’ve speculated and works efficiently.
