Glucomannan Appetite Suppressor – Clinical Proof

All about GlucomannanGlucomannan is a high-fibre root extract sourced from a perennial plant called konjac.

It’s often used as an appetite suppressing ingredient in diet pills and it’s ability to control hunger has been put to the test and proven in numerous clinical trails.

Although the root extract is sometimes listed on diet pill bottles under the name “konjac”, glucomannan is the name most commonly used.

Glucomannan: An Appetite Suppressor

Despite the fact that in some Asian countries glucomannan flour is used to make noodles, the ingredient has very little nutritional value and contains next to no calories at all.

However, the fact that it’s ultra low in calories is neither here nor there.

Glucomannan’s real value as a weight loss aids is due to its phenomenal ability to soak up water.

When glucomannan is combined with water, it can absorb up to 50 times its own weight in liquid and the resulting combination is an nondigestible gel that fills the stomach and takes away the appetite.

Glucomannan: An Appetite SuppressorCalorie Reduction and Weight Loss the Glucomannan Way

When people talk about calorie restricted or low-calorie diets, they are talking about a diet that is designed to deliberately cause the body to experience an energy shortage.

A calorie is a unit of energy and the calories in food are the fuel that powers the body. When people overeat or eat too much high calorie food, the body gets more calories than it needs and stores the excess as fat.

When the situation is reversed, the body reclaims calories from its stores of fat and burns them to get energy. It’s quite simple really.

The hard thing is sticking to a diet that is low enough in calories to cause the desired fat burning effect.

Many failed dieters saw their dreams of a slimmer body go up in smoke because the hunger pangs they experienced were too powerful for them to bear.

A full stomach is a happy stomach, but food is not needed when the stomach has been filled with glucomannan gel.

Proof That Glucomannan Works

Numerous studies show glucomannan is an appetite suppressant that works. After one eight-week double-blind placebo study, involving 20 obese individuals, the researchers noted a “significant weight loss” that was accompanied by a lowering of the volunteers’ cholesterol levels.

In a much larger study, Norwegian researchers enlisted the help of 176 volunteers and assigned each of them a place in one of four groups.

  • Group one received glucomannan only
  • Group two got glucomannan and guar gum
  • Group three were given glucomannan and alginate
  • Group four got the placebo

All four groups were put on a calorie-controlled diet. The members of all four groups successfully lost weight, but the placebo group lost less than the other three groups and the member of group one (glucomannan only) lost the most weight of all.

This lead the researchers to conclude:

“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.”

Additional Benefits

A number of other claims are made for glucomannan, but its ability to support weight loss and control cholesterol are the only two that can be supported by sufficient scientific proof.

However, glucomannan is also believed to be capable of slowing nutrient absorption rates sufficiently to prevent post-eating blood sugar spikes and the resulting rush of insulin that can force the blood sugar to drop so low it initiates a desire for high-calorie food.

Glucomannan is also believed to be capable of boosting friendly gut-living bacteria (prebiotics). When this kind of bacteria flourishes it’s believed to be very beneficial for the health and may have the potential to improve weight loss.

The Bottom Line

Glucomannan’s ability to fill up the stomach and limit the desire for food has been proven by science.

It works well, suppresses the appetite in a very natural way, and is unlikely to cause side effects like certain other diet pill ingredients do.

It’s alleged potential in other areas is certainly interesting, and future studies may prove some of the theories about glucomannan that are being presented today.

However, as far as weight loss goes, the only proven certainty is glucomannan is an appetite suppressing diet pill ingredient that works.

Phentatrim Review – what are people saying about this appetite suppressant

Phentatrim reviewPhentatrim is a diet pill brought to market by Optimum Nutra. It’s suitable for vegetarians and also has the benefit of being stimulant free.

Like many competing products, Phentatrim is designed to make it easier for dieters by controlling their hunger.

The fact that it contains an effective dose of a respected appetite suppressant (konjac) is good but does not make Phentatrim unique because a number of of competing products do the same.

However, Phentatrim also contains two other powerful ingredients that have abilities that combine well with those of glucomannan and give Optimum Nutra’s product an edge that bog-standard glucomannan products cannot match.

Phentatrim is made by the same company that has given us Phentaslim (a fat burner) – when these two diet products are combined it produced a excellent weight loss stack

What are the Phentatrim Benefits?

  • Suppresses the appetite and provides hunger control
  • Supports healthy thyroid function
  • Increases energy levels
  • Improves bowel health
  • Contains EFSA approved ingredients

Who Can Use Phentatrim?

Phentatrim is intended to help men and women who need to lose weight, whatever their age or level of personal fitness. However, as with any other supplement, people who have existing health problems are advised to get a doctor’s approval prior to commencing supplementation. The same advice is offered to women who are pregnant or breastfeeding a child and to people who are using medication.

What Is the Recommended Dose? The recommended dose is two capsules and three doses are needed each day. Each dose must be washed down with one to two glasses of water and should consumed 20-30 minutes before meals.

What Are the Ingredients Used in Phentatrim?

Two capsules provide:

  • Konjac (1000mg)
  • Chromium (24µg)
  • Iodine (90µg)

Can the Phentatrim Formulation Do the Things It’s Supposed to Do?

The formulation contains respected weight loss ingredients that have the ability to ensure the product works in the way it’s designed to do and offer dieters the support they need to lose weight in a safe and effective way.

Konjac (glucomannan) is a natural fiber taken from the roots of a plant and, like any other dietary fiber, it’s good for improving bowel health and lowering cholesterol levels. There are two kinds of dietary fiber.

Glucomannan appetite suppressant

The first is insoluble fiber. The second is soluble fiber. Konjac is the second type. That means it dissolves in water and forms a gel. It’s not alone in this ability. Other ingredients, including psyllium husk and oats, do it as well.

However, konjac is much more absorbent and can soak up 50 times its own weight in water. This ability has allowed konjac to gain an unprecedented amount of respect as an appetite suppressant.

It works so well because, when konjac is taken with enough water, the resulting volume of gel fills up the stomach sufficiently to make it feel full. In order to provide good results, konjac has to taken three times per day and each dose must provide 1000mg.

It also has to be taken with one or two glasses of water, before eating a meal. The Phentatrim formulation and usage guidelines are perfect because they ensure users get the maximum benefits.

The final two inclusions are chromium and iodine. Research shows Chromium improves insulin sensitivity and glucose control and significantly reduces body fat.

It’s also known to be capable of increasing energy levels by encouraging the cells to take in extra glucose. Iodine also has value because it helps the thyroid gland to produce important hormones that ensure a healthy metabolism. This is important because the metabolism controls the rate at which calories are burned and boosting the metabolism is a very good way to lose weight.

Does Phentatrim Have Good Customer Reviews?

There are a lot of customer reviews and all of them are good. Some typical reviews read:

“I’ve only been using Phentatrim for 4 weeks but I’ve already lost 9lbs in weight. That’s no big surprise for me because taking these capsules before meals makes it impossible to get greedy and pig out. I’ve tried lots of other diet pills in the past, but nothing I’ve used ever worked as well as this.”

“The appetite suppressing capability of this product is first-rate and I’m presently finding it very easy to lose weight because eating less is not a problem when the hunger urges are gone. I’ve also noticed a definite increase in my energy levels and haven’t experienced any side effects at all.”

“This product does everything it says on the tin. The appetite suppression provided by the pills kicks-in fast and makes it impossible to overeat at mealtimes. Since starting with them I have also found I no longer have any urges to snack. I have more energy now and I’m losing around 10lbs per bottle. Easily the best diet pills I’ve ever used.”

Starlight FatFree Review – Pros and Cons

Starlight Fat free AustraliaStarlight FatFree is one of a number of health and wellness products brought to market by Starlight International.

The company was founded by ex-Hollywood producer Steven Goldberg, who apparently wanted to use his people skills and business expertise to create a company that “makes a positive difference in the world”.

Which appetite suppressants are most popular according to consumer feedback

What is Starlight FatFree and How Does it Work?

According to the marketing material, Starlight FatFree “helps to prevent the absorption of fat and then expels it from the body”.

Supplements of this nature are commonly called fat blockers. The FatFree formulation appears to have little value in this regard but it contains glucomannan, so it could be a potentially good appetite suppressant and the pills also contain some herbs to help people become “slim, healthy and in control”.

Key Ingredients

Each (2 tablet) serving provides:

  • Glucomannan (1000mg): A super-absorbent natural fibre taken from the roots of the konjac plant. When taken with plenty of water, the fibres expand in the stomach and create a feeling of fullness that dulls the appetite. Clinical trials prove glucomannan works, but guidelines provided after an evaluation by the European Food Safety Authority (EFSA) state three doses are needed per day. The EFSA also state the minimum dose should be 1000mg (taken with 1-2 glasses of water) and stress the importance of eating sensibly. The dose provided here is sufficient, so anyone who takes three doses of Starlight FatFree per day, before meals, and with the required amount of water, should find their appetite decreases.
  • Maitake Mushroom Extract, 4:1 (50mg): An ingredient that is highly valued in Japan, where it credited with incredible powers of healing. Maitake is an adaptogen. Ingredients of this type help keep the body’s systems in balance, fight disease, and enhance physical and mental health. Although the significance of “4:1” is not explained in the marketing material, it suggests the extracts have been concentrated to four times normal strength. If this is so, the 50mg dose provided here is the equivalent of a 200mg dose of normal strength maitake mushroom extract.
  • Platycodon Grandiflorum Extract, 5:1 (140mg): Also known as balloon flower, platycodon grandiflorum is grown as an ornamental flower in countries all over the world. A scientific evaluation of its many alleged health boosting abilities suggests supplementation with platycodon grandiflorum may improve insulin resistance and help prevent the absorption of dietary fat. However, further study is needed, and the fat blocking ability of platycodon grandiflorum is unlikely to be as good as nopal or chitosan. The extract used here appears to have been concentrated to five times normal strength.
  • Gymneme Sylvestre (100mg): An Indian/African shrub extract that is often used in Ayurvedic medicine. It appears to have the ability to decrease sugar absorption rates in the intestine and may have value as a possible treatment for diabetes.

Usage Instructions – Two tablets are required 30 minutes before eating a meal. The tablets should always be taken with 8oz of water and the maximum dose is 6 tablets per day.

Starlight FatFree Side Effects & Health Issues

Starlight states FatFree is not intended for people who are under 18 years of age. Women who are pregnant or lactating are advised to get medical advice before starting supplementation.

People who are using prescription medication should time the doses so there is a two hour gap between taking the dose of medication and the dose of Starlight FatFree. The maximum dose of six capsules per day should never be exceeded.

Where To Buy Starlight FatFree

A bottle of Starlight FatFree costs $35 from the Starlight website, but interested parties will need to register with site and set up a new account before they can place an order.

Starlight also offers a multi-level marketing (MLM) business opportunity so, in theory, it should also be possible to buy Starlight FatFree from a distributor. However, we were unable to find any distributor-run sites.

This is unusual for an MLM company and suggests a lack of interest in the Starlight business opportunity.


A 30-day money back guarantee is promised.

Customer Feedback

Customer feedback is limited to a few short, but positive reviews published on the manufacturer’s website. All of the reviews have been placed by Starlight distributors and are unlikely to be unbiased because the distributors have a vested interest in the product’s success.

The Bottom Line

Although the key ingredient here is undoubtedly glucomannan, the other ingredients are not without promise and, on the face of it, Starlight FatFree does not appear to be without potential. However, the formulation is unlikely to have much (if any) value as a fat blocker.

The lack of reliable customer feedback is also an issue with this product. All the top diet pills have plenty of good reviews and generally come with a longer money back guarantee.

Thirty days does not provide customers with a long enough period of time to try the product and see if they are happy with the outcome. Starlight FatFree is not without promise, but there are several better options available.
