Bone Hormone Linked to Obesity and Diabetes 218
grrlscientist writes "New research has shown that the skeletal system may be an important player in preventing obesity and type-2 diabetes in animals. This may also be true for humans, and thus represents an important development for the treatment of these health conditions. From the article: 'Not only do bones produce a protein hormone, osteocalcin (pictured), that regulates bone formation, but this hormone also protects against obesity and glucose intolerance by increasing proliferation of pancreatic beta cells and their subsequent secretion of insulin. Osteocalcin was also found to increase the body's sensitivity to insulin and as well as reducing its fat stores ... "The skeleton used to be thought of as just a structural support system. This opens the door to a new way of seeing the bones," said Dr. Gerard Karsenty, chairman of the department of genetics and development at Columbia University Medical Center in NYC, who headed the team that made the discovery.'"

Every time I see a news story that is 'blah blah 40% of the population is obese' I often wonder where these people are.
All around you, they just don't _look_ like it.
That statistic you hear is based on BMI. BMI is, at best, an unreliable indicator for a) whether or not someone "looks obese" (obviously very overweight, rolls of fat, multiple chins, no muscle definition anywhere, etc, etc) and b) whether they're "unfit" (gets puffed running up stairs, does no exercise, etc).
For example, I have a BMI of about 31 (=medically obese). However, I'm 189cm and "built like a tank", so while I definitely have a pot belly, I doubt many people would look and consider me "obese" - especially since I have reasonably good muscle definition on my arms and legs. I cycle a ~25km round-trip to work (without raising much of a sweat) and play a 40 minute game of indoor soccer once a week (again, without feeling exhausted afterwards). So while overweight, I'm not really unfit and I can't think of anyone who has ever referred to me as "obese" or looked at me in that "I can't believe you're so fat" way. However, my weight has been stable at its current level for 5+ years now and short of seriously intrusive dieting (= food I didn't really enjoy eating and feeling hungry 24/7) I haven't been able to lose it (or, rather, I did but it came back).
The "best" my BMI has ever been was 24.something, back in the middle of high school (just under "overweight"). I was about 180cm and weighed around 80kg. At the time, I was cycling ~30km daily (to and from school), training 1-2hrs a day for soccer and/or volleyball, swimming a kilometre ~3 times a week and playing 3-5 games of very competitive soccer and/or volleyball every week. For the last two years of high school, with a similar level of exercise, my BMI rose to (just) over 25. So I would have fit into that x% of the population that was being reported as "overweight", despite being extremely fit and not *looking* at all overweight.
The short version is, a hell of a lot of people are medically overweight or obese, but don't look it because of their body type - they just look "pudgy". That's where most of that "x% of the population is obese" is hiding.

Re:May Partially Explain Why Exercise Helps (Score:5, Insightful)
Exercising burns up glucose and puts a demand on your body to change how it processes foods. As a result of these changes your body's metabolism increases not only the rate at which it burns calories during exercise but it will also be elevated for a good amount of time afterwards. This means that you burn calories for the actual exercise done but you will also burn more after you have finished exercising, taken your shower, and sat down at your desk to do some work. Here is an article [about.com] on this phenomenon.
In addition, by exercising you are telling your body that changes need to be made. Part of exercise is the microscopic tearing of muscle fibers, stress on capillaries and other transport systems within your body, and the release of various hormones related to your exertion. Your body's overall response is to rebuild and bolster these systems. You grow more muscle tissue, your capillaries increase their ability to carry more blood, various organs and cellular structures configure themselves for the next bought of exercise. All of these actions take energy and they put food to a better use than simply turning into fat around your waist.
Finally, now you have more muscle mass, better circulation, and so on. This generally results in an overall higher metabolic rate because your body has prepared itself to provide you with more energy at all times. The higher metabolic rate burns more calories even when you aren't exercising and allows you to exert yourself even more the next time you do exercise.
So there's a lot more going on than the simple "1 Calorie will lift 155 pounds to 20 feet in the air". You body changes with exercise and that is where the real weight loss begins.

What exercise does do though, is build muscle mass. Muscles (even at rest) use a higher number of calories than fat cells do.
