Source. This venomous lizard, Heloderma suspectum, harbors a billion dollar secret: a special protein in his saliva and tail. That protein, exenatide, is highly effective in treatment for type 2 diabetes. As American's girth and weight continues to increase, so does type 2 diabetes. It is a vicious cycle: Increased obesity leads to more enlarged fat cells that respond less and less to insulin needed for control of blood sugar - a hallmark for type 2 diabetes. This leads to increased appetite and overeating and obesity. And the cycle continues. The protein isolated from the Gila monster…
Photo by flickr user gato-gato-gato. Did you ever watch cattle? I mean, really watch them, for a few hours? Mostly they just sit or stand around munching on grass, chewing their cud, or snoozing. But every once in a while a handful of them will stand up and point in one direction. And they may take a few steps in that direction. Then a few more will join them. And once a critical mass has been reached, the whole herd will just go. Domestic cattle, wild African cape buffalo, whatever. This is what they do. And as the cattle do, so do bloggers. And one day one, then another, then another of…
The Biggest Loser is a TV reality show on which people who really do weigh a lot more than is healthy compete to lose weight. They do this on teams. There are various challenges. There are charismatic trainers. And, of course, because it is a TV reality show, individuals can get tossed off the show either because of poor performance (not losing enough weight) or by getting voted off. An interesting and entirely inappropriate trend has developed on this show. Individuals decide that they should leave the show while others must stay. They accomplish this by gaining, rather than losing,…
Gym regulars might grumble when classes and locker rooms fill with resolute new members each January, but the crowds rarely last long. I'm sure many gyms' revenue models depend on members who pay monthly fees but use the facilities infrequently, if at all. These people (and I've been one in the past) are essentially throwing money away by not going to the gym, but that doesn't seem to be enough to get them out of bed and into spinning class at 6am. The rewards of better fitness are much more distant than the allure of another half hour of sleep. The Boston Globe's Susan Johnston reports on a…
NBC photo Contestants on NBC's "Biggest Loser" In Woody Allen’s Sleeper, Miles awakens after a 200-year sleep, to a world in which healthy food choices have become topsy-turvy: Dr. Melik: (listing items Miles had requested for breakfast): "... wheat germ, organic honey, and... Tiger's Milk." Dr. Aragon: "Oh, yes. Those are the charmed substances that some years ago were thought to contain life-preserving properties." Dr. Melik: "You mean there was no deep fat? No steak or cream pies or... hot fudge?" Dr. Aragon: "Those were thought to be unhealthy... precisely the opposite of what we now know…
NBC's "Biggest Loser" has become a phenomenon, with over 10 million regular viewers. There is no doubt that this show delivers dramatic entertainment. Sagas about victory of the human spirit, against all odds, are timeless. With the final four contestants being featured next week, I would like you to consider the message that this show coveys. Public embarrassment defines much of today's entertainment - consider the sharp wit of "The Office". The German term, Schadenfreude, expresses it well - deriving pleasure from the misfortunes of others. On the "The Biggest Loser", each contestant…
As the heat drags on in the southwestern United States, I cannot stop dreaming about sledding through the snow. So I checked out the trusty American Physiological Society press releases to see what the animals might be doing in cold environments that I can only dream about these days. In my search I watched a really neat video of Dr. Michael Davis (Center for Veterinary Health Sciences at Oklahoma State University) who works on perhaps one of the "coolest" animals (pun completely intended): sled dogs! Oh, how I envy these animals. Racing sled dogs are incredible athletes as they traverse the…
A recent paper provides the groundwork to establish a way for exercise to diminish appetite. Or, more likely, for sedentary behavior to increase appetite. It is well known that exercise burns calories. Personally, I think that's overrated: Strength building raises your metabolic demand, and THAT burns calories. But that is not the main topic at hand. New research indicates that exercise also increases the sensitivity of neurons that are related to the control of the feeling of satiation. Therefore, you feel full rather than hungry sooner and/or more often. In rodents. So far. The…

 Image by Jespahjoy. Just before moving to our new home here on Scienceblogs, I asked our readers for ideas on what types of content they would like to see here on Obesity Panacea.  One topic that came up several times was the issue of injuries.  I'm not sure why we haven't discussed injuries in the past (aside from the fact that it's not the focus of our research), but it was a great idea, and I've come across a study on the topic that I think will be of real interest.  The study is titled "The influence of exercise and BMI on injuries and illnesses in overweight and obese individuals: a…
Image by atomicjeep I came across a very interesting article in the Ottawa Citizen this weekend, unpleasantly titled "For Canada's obese, exercise alone isn't going to cut it". The crux of the article is this - exercise will not help you lose weight. Every few months it seems that this issue pops up, including a cover article in TIME magazine last year, which Peter has previously dissected. This is a complicated issue, and given the sensational title, I wasn't expecting much from the Citizen article. But the article is actually very well written, and includes interviews with a number…

Found this in the Washington Post: Using data gathered from such sources as the U.S. Census and the Centers for Disease Control and Prevention, the ACSM developed a fitness index that covered 27 aspects of local environment and health, from death rates from diabetes and cardiovascular disease to the number of baseball diamonds and playgrounds. San Francisco ranked No. 1, with an index score of 403, partly on the basis of lifestyle and health factors such as the relatively high number of people who report exercising at a moderate intensity (55.6 percent, compared with an average of 48.4…
Thank you, NYTimes, for clarifying something I have always wondered about: how does running outside compare to running on a treadmill? A number of studies have shown that in general, outdoor running burns about 5 percent more calories than treadmills do, in part because there is greater wind resistance and no assistance from the treadmill belt. Some studies show, for example, that when adults are allowed to set their own paces on treadmills and on tracks, they move more slowly and with shorter strides when they train on treadmills. I will say that in my case outside running burns more…

"A lot of people know from their own experience that when they exercise, they feel better," observed James A. Blumenthal, a professor of psychology at Duke University and lead author of a newly published study that examined the relationship between exercise and depression. But does this anecdote hold up when examined in a scientific study? And how much better does exercise make one feel? According to this study, exercise is as effective at reducing the…
