Brain Degeneration and Obesity

"The brains of obese people looked 16 years older than the brains of those who were lean, and in overweight people looked 8 years older."

This is quite shocking news. Just one more item added to the long list of negative health effects obesity leads to. Also mentioned in the article is the fact that age didn't matter, this effect spanned all age groups. The loss of brain tissue increases the risk of alzheimers as well as other forms of dementia.

The areas affected were those related to planning and memory, executive functions and attention as well as long term memory and movement.

Those with the loss were in the BMI categories between 25-30 (overweight) and over 30 (obese).

Fat People Live Longer?

Hold down your excitement. Before you run off and tell everyone you know that a new study says fat people live longer lets look at what it really says. What the study found, based on BMI, which only takes into consideration height and weight, not muscle and fat, was that those in the overweight category, 25-30 BMI were 17% less likely to die than those of 'normal' weight, BMI 18-25. Instead of saying of yes, now I can eat all I want and not worry because being overweight is good, look at what it really says. If your risk of death is 10% then the risk for overweight people, based on BMI, is 8.3%. Essentially what this means is that focusing solely on weight as an indicator of health is not the thing to do. That fact has actually been known for quite some time. What this also really says is that being fit and regularly exercising is more important than reaching a certain 'weight loss' goal, particularly for those without weight related health problems. It's been shown for quite some time, and confirmed by a 2005 US study that those who are still technically considered 'overweight' but are fit live longer than those of normal weight who don't exercise. Definitely a word of caution to those who don't workout because they think they don't need to because they are skinny, you are actually at a greater health risk than those who are a bit larger. All in all what this says is that weight isn't the only factor and fitness plays a huge role in overall health and longevity.

More on Obesity Cost

This staggering $147 billion medical cost of obesity is nearly double what it was 10 yrs prior.

If you're obese on average your medical costs will be 47% higher or in dollar figures almost $1500/year as compared to someone who is not obese.

Nearly all of this is attributable to the costs of disease brought on by obesity.

What this says in my estimation is two-fold, one people need to start taking responsibility for their lives and actions and two it's obvious we need to re-evaluate how we are addressing the obesity problem which I will address in the next post.....what this relates to is the fact that there is much more to it than just eating right and exercising....this fact research is even beginning to validate..
