New Product 2good2btrue
I started using a new product that i got from GNC, called Tetrazene.
This is by far the most effective diet product that i have used. It is made for low-carb dieters to help with sugar and hunger cravings, and unlike other crap that I fell for, this stuff does exactly what it claims to do. In the past 2 weeks, I have lost an additional 9 lbs, beyond the low-carb average weight loss (which without the Tetrazene was between 2-3 lbs per week). My question is does anyone know anything about this product (Bioquest is the maker of it). According to the pamphlet it is 100% safe and healthy. One thing I noticed is that my body seems more regular than ever. But I can't find any info on the active ingredient which is called KGM extract. Any info out there? |

I checked the website, and found on the bottom, there were footnotes
with the studies listed. I have no idea what this information means: Scientific References of KGM (Konjac Glucomannan) 1) Walsh DE, et al. Int J Obes. 1984;8(4):289-93. 2) Vita PM, et al. Minerva Med. 1992 Mar;83(3):135-9. 3) Reffo GC. Curr Ther Res. 1988;44:22-27 4) Doi K, et al. 1979 May 5;1(8123):987-8. 5) Vuksan V, et al. J Am Coll Nutr. 2001 Oct;20(5 Suppl): 370S-380S; discussion 381S-383S How does a normal layperson go about getting the actual information rather than just these abbreviations? From reading the whole ad there has to be a catch... (jamie) wrote in message ...

The place to go is to your local Library... and ask for help from a librarian. The Librarian can help
you with the names of the journals and the citation information (author, title, volumes, dates, page numbers, etc) The library can also get copies of the articles through ILL (Interlibrary Loan) or identify a library that has the issues so you can get them yourself.

But they don't add up to much. Setting the first two aside a moment, the last three don't amount to diddly, as is usual with advertisement "evidence" two aren't studies, and one has to do with the product's claims: 3) Reffo GC. Curr Ther Res. 1988;44:22-27 All I could get on this one was the title: "Glucomannan in hypertensive outpatients: pilot clinical trial" A trial using it for high blood pressure? What's that got to do with evidence for weight loss? No wonder they don't include the titles in these references. 4) Doi K, et al. 1979 May 5;1(8123):987-8. Merely a letter published in Lancet magazine, not a study. The letter's contents are not listed, but was apparently not about weight loss, as the entry is titled "Treating diabetes with glucomannan" 5) Vuksan V, et al. J Am Coll Nutr. 2001 Oct;20(5 Suppl): 370S-380S; discussion 381S-383S This is not a study either, it was an article about looking *into* researching glucomannon as alternative treatment for diabetes, not about weight loss at all. The article can be found at http://www.jacn.org/cgi/content/full/20/suppl_5/370S Now we can look at the two that at least *were* studies about glucomannan for weight loss. 1) Walsh DE, et al. Int J Obes. 1984;8(4):289-93. Small and brief study consisted of only 20 people, for 8 wks, of which only 10 took glucomannan, and 10 took placebo. In an article on the case of the FTC vs SlimAmerica, for diet product fraud including glucomannan, This study was mentioned. Dr. Barrett, the Vice President of the National Council Against Health Fraud, comments on that study: One expert on the panel referred to a 1984 study of glucomannan that reported weight loss of 5.5 pounds over 8 weeks without any changes in diet or physical activity. Walsh, D.E., et al., Effect of Glucomannan on Obese Patients: A Clinical Study, 8 International Journal of Obesity 289-93 (1984). In this study, patients were instructed not to deviate from their previously established eating and exercise patterns. This study is not particularly persuasive given the small number of subjects in the treatment group (10) and the fact that subjects did not maintain appropriate food diaries. There is no way to be sure that subjects did not change eating patterns. In fact, one of glucomannan's purported mechanisms of action is as a bulking agent, and the authors note it "added bulk in the stomach just before each meal, [which] may decrease the appetite and [cause subjects] to eat less at each meal." 2) Vita PM, et al. Minerva Med. 1992 Mar;83(3):135-9. Another small and brief study very similar to the first one except that participants were put on a low calorie diet as well as taking glucomannan before meals. 25 people, 3 months. The brief Medline summary doesn't say what they lost, but the lack of any larger follow-up study suggests it was as flawed as the first one. In contrast to these, here is a reference the ads don't mention, showing NO weight loss from glucomannon. Quoting from an article by the aforementioned Dr Barrett, "Bulking Agents" and Weight Control" http://www.canoe.ca/HealthAlternativ...ns/010726.html "In 1980, Dr. Judith Stern of the University of California conducted a double-blind study in which the test group received 1 gram of glucomannan before meals, while the control group received a placebo. Both groups participated in a behavior modification program and lost weight, but no statistically significant difference in hunger ratings or weight loss was found between the groups." Meanwhile, I believe I mentioned yesterday the study where glucomannon showed no weight loss results better than much cheaper pectin fiber, both being used to take up room in the stomach before meals. How does a normal layperson go about getting the actual information rather than just these abbreviations? http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed -- jamie ) "There's a seeker born every minute." |

I have taken products with the active ingredient, konjac, aka
glucomannan, in the past and I have seen favorable results. Here is another unbiased link that will be helpful in understanding the effects of this ingredient. http://www.supplemen****ch.com/supat...pplementId=358 |
