Hi guys! While I think that anything that motivates you to eat well and exercise (like being healthy and wanting to feel better about yourself, have a good quality of life, and being a good role model) is awesome, I think this prediction is media hype. I keep an article from scientific america that I clipped out regarding the "overblown obesity epidemic". It talks about the common perception that overweight=unhealthy, and that obesity is going to become the #1 killer in North America. The major study in which the prediction that has been often-quoted by the media about life expectancy falling because of obesity (which was published March 2005 in the New England journal of medicine) predicted that obesity will cause a 2-5 year decrease in life expectancy. The scientists who did this study made a number of assumptions (for example, they came up with the 2-5 years by comparing our society with a utopia where everyone was a normal weight, and there were no excess deaths caused by underweight, which actually has considerable health risks associated). They used old "risk" data, which did not account for advances in medicine in the past decade. Other studies have shown no statistically significant risk of excess deaths in obese populations.
Sorry, didn't really mean to rant about that study as much as I did; there are links of obesity to certain diseases like diabetes and heart disease to be sure, but it seemed a bit like sensationalism. My favorite analogy ever was of obesity to smoking. Yellow teeth and fingers aren't a cause of lung cancer, but smoking causes yellow teeth and causes lung cancer. Being obese doesn't cause diabetes and heart disease; poor nutrition and lack of exercise do.
I felt so relieved when I read that; it's help me forget the scale and focus on being healthy. I always felt like I "should" be a certain weight, and then I would be healthy - once I reached that BMI range I would be out of the "risky" area health-wise. Even when I was my most fit and eating well I felt like it was pointless because the scale told me that I still wasn't a normal, healthy weight. But now I check to see how many fruits and veggies and lean meats I've eaten, and how often I've made it to the gym or some kind of activity to judge. For me, it's those habits I want to pass down to the next generation, not monitoring my weight.
