While waiting for a friend to show up for coffee, I ran into an ad in a local newspaper. I was thrilled to find the exact ad online! It's for a medication that claims to target and eliminate belly fat, supposedly developed by the well-known cosmetic surgeon, Frank Ryan.
Normally, I just disregard these things, but this one included references to trials and even had footnotes! My curiosity was piqued... Some claims in the ad include:
Abdominal fat is the most stubborn fat to reduce and it is also the most hazardous fat to health. Abdominal fat produces destructive hormones that spread throughout the body. A clinical study has shown that Dr. Frank Ryan’s Abdominal Fat Reducer can reduce your pot belly without changing your diet or physical activity.
Here, the mechanism by which this works is suggested:
How does Dr. Frank Ryan’s Abdominal Fat Reducer work? Paul Klingaman, Executive Director of Endless Youth and Life explained. Klingaman revealed, "It was found in a number of research studies on laboratory animals and later confirmed in human studies, that a substance called Conjugated Linoleic Acid (CLA) decreases abdominal fat in three ways:
[... three ways are listed ...]
... Dr. Frank Ryan's Abdominal Fat Reducer contains the effective dose of CLA.
Continuing on, we have this quote which ends by citing three footnotes:
Studies have shown that Dr. Frank Ryan's Abdominal Fat Reducer ingredients increase the rate of metabolism, which reduces both surface and intestinal abdominal fat and helps inhibit future formation of these abdominal fats. 3, 4, 5

From my high school health class (which, admittedly, was about 10 years ago), I recall being taught that one couldn't "target" specific fat in the body to burn with exercise. This is using medication, however reading about a method to specifically remove abdominal fat has me skeptical.
Is there evidence to support that the use of CLA in Frank Ryan's Abdominal Fat Reducer (or any of the other ingredients -- they cite Green Tea extract as well) will target and reduce specifically abdominal fat without one changing diet or exercise habits?
In searching for "AMJ," I was able to find
- Academy of Management Journal (not likely)
- Australasian Medical Journal (I was hopeful, but their archives only go back to 2009, so I'm thinking they aren't the AMJ responsible for a 1989 publication).
- Oddly enough, in continuing to search for this, I ran across this blog post, supposedly written by a doctor, who was also examining this full page advertisement! Her conclusion was not very hopeful.
The Metabolism article has to do with caffeine responses in women... I'm not sure if this implies that caffeine is one of the ingredients in this product, or if they cite the study for some other reason.
