Is this patently aburd - or a miracle come true?
As Seen in Women' World tabloid It's been advertised in many places recently, mostly newpapers and supermarket tabloids. In fact the ingredient in this product is not new at all, it's name has been changed to suit the place where its advertised.
The original patent goes back to 1994, see more below. It's for something they call 7-keto-DHEA (the real name is much longer).
7-keto-DHEA is for sale, under license from the original patent holder, on several sites around the country. The product seems to morph itself into a whole bunch of names, according to who they are marketing to. According to Dr. Zenk since his company, Humanetics owns the intellectual property rights and is the sole supplier of the "Ingredient" , customers who wish to use 7-Keto in their weight loss products must license the use of the "Ingredient" the company. Those other companies can all it whatever they want. Thus, the company called PatentHEALTH, LLC called it PatentLEAN. Now does that make things crystal clear?
There are no patents registered with the U.S. Patent office web site under the name PatentLEAN.
This is one of two patents from 1994 that contain the active ingredient which would seem to be a type of DHEA compound.
I don't see any definitive evidence presented on this U.S. patent site that would leave me to believe the claims made by the company in the advertisement above.

Claim 7-keto-DHEA is for anti-aging.

Claims that DHEA is a successful "anti-aging" substance. - Well, I'll be, where is the data for those wild claims? So what that most of the claims are for rats, younger, leaner, less forgetful rodents. That's just what I need. Pass the cheese please, and hold the mustard.

Send for your own video or watch on RealPlayer. I loved the CBN piece with former right wing fundamentalist leader of the moral majority movement, Pat Robertson, who interviewed Zenk. Of course he hit Fox and all the rest of them.
- Studies posted on their web site reveal a study done in 30 obese people over a relatively short period of time. In fact it was only 8 weeks long. That is ridiculous!!! It seems to me that they may have actually used the same study twice. Eight people dropped out of the original cohort of 30 people. What happened to them? You will note that the product was not named here.
- This ridiculous site sells 7-keto-DHEA products that seem to be linked to comments about ephedra. This was a direct link from the humaneticscorp.com web site above. It is very confusing and I have e-mailed them to clarify the situation. It is obvious to me that if this was
mixed with ephedra, it would not be what the company intended.

Humanetics Licenses Patents
MINNEAPOLIS--Humanetics Corp. licensed pharmaceutical rights to its patents
on 150 compounds to Hollis-Eden Pharmaceuticals Inc., which will evaluate the
compounds for possible use in pharmaceutical products. Humanetics' 7-Keto is
among the licensed compounds.
"It won't affect anybody in the supplement industry [adversely]. If anything, it may
help," said Humanetics president Ronald Zenk. "We're going to continue to sell
7-Keto as a dietary supplement, and Hollis-Eden will evaluate 7-Keto amongst the
other 149 compounds and compare it and choose which compounds they'd like to
use in pharmaceutical development."
Well, when did they evaluate 7-keto-DHEA for weight loss? What were those results?

- Search Google for 7-keto diet claims - Note the overwhelming number of vendors here, with almost no peer reviewed studies that have been replicated.
- FTC report on diet and weight loss claims has this to say about advertisements:
Although some advertisements briefly describe the results, and provide some information about the methodology, of a particular study, sucha as the studies duration and number of participating subjects, most of the advertisements fail to give consumers sufficient detail to allow consumers to verify gthe advertiser's representations. Moreover, 20 of the 117 ads make "clinically proven" claims were for products that contained ingredients already evaluated by the Federal Trade Commission in the context of past law enforcement actions challenging specific weight loss claims. These ingredients, which include fucus vesiculosis, chromium, L-carnitine, chitosan, psyllium, 7-keto-DHEA, hydroxycitric acid, seaweed, konjac root, garcinia cambogia and glucomannan, were challenged based on insufficient scientific evidence to support weight loss claims made in the advertisments.
- FTC actions against 7-keto vendor for making anti-aging claims
- Supplementwatch.com comments:
The scientific evidence for using 7-Keto as either an anabolic agent or for promoting weight loss is quite weak
and more research is needed to substantiate if any of the popular claims made for this supplement are indeed
justified.
7-Keto appears to be safe in doses of 200mg per day. The two human trials to date have not shown any
androgenic or estrogenic effects of high dose supplementation. Many of the claims for 7-Keto are based on
petri dish studies, animal research and cell line studies, thus the data and findings cannot be carried over to the
human model.

PHARMACISTS WARNED ABOUT "WEIGHT LOSS" PRODUCTS
The April 2002 issue of Pharmacist's Letter told pharmacists to advise patients to avoid products containing the following "natural weight loss" ingredients,
especially if they are combined with caffeine, guarana, cola nut, mate, or tea: conjugated linoleic acid (in Body Solutions, Diene-O-Lean, Tonalin), 7-keto
DHEA (in PatentLEAN, 7-Keto Fuel, 7 Keto Lean)-because little is know about its long-term safety, hydroxycitrate (in Citrimaax, CitriLean, Diet Fuel,
Herbalife), ephedra (recalled in Canada), and bitter orange or country mallow (heartleaf) which contains ephedrine-related compounds. Pharmacist's Letter
did not mention that pharmacists can help patients avoid products of unproven safety or effectiveness for weight loss by not selling them.

I was contacted by his lawyer in September 2004 and he requested that
I update my web site. When John Zenk was ordered to surrender his
Minnesota license it was in September 1999. He was
without a valid license until March 9, 2002 after he reapplied.
There are no restrictions on his new Minnesota medical license.
