People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Healthy obesity a myth, say researchers

RATE THIS! +35

Obesity brings increased risk regardless of cholesterol, blood glucose and blood pressure readings. It carries an additional risk of premature death compared to that of normal-weight individuals, regardless of the obese person’s cholesterol and sugar levels, a study from Mount Sinai Hospital’s Lunenfeld-Tanenbaum Research Institute shows.

 

“Our research findings challenge the myth that there is such a thing as healthy obesity if people maintain normal-range readings of cholesterol, blood glucose, and blood pressure,” says co- author Dr. Ravi Retnakaran, an endocrinologist at the Leadership Sinai Diabetes Centre at Mount Sinai Hospital in Toronto, and Associate Member of the hospital’s Lunenfeld-Tanenbaum Research Institute. Co-authors are Dr. Caroline K. Kramer and Dr. Bernard Zinman, also of the Lunenfeld-Tanenbaum Research Institute.
 
Researchers reviewed the data of 61,386 individuals in eight separate studies from the past decade.  Each study observed adults defined as normal weight, overweight, and obese (body mass index or BMI of 30 or greater). Each study evaluated the individuals’ metabolic status, i.e. cholesterol levels, blood sugar levels, and blood pressure. The studies compared fatal and nonfatal cardiovascular events such as heart attack and stroke, as well as other causes of death, across the three weight categories. 
 
The comparative risks for premature death in the three weight groups became especially apparent after 10 years of follow-up. The key finding is that even in the absence high blood pressure or cholesterol (in other words, a metabolic problem), an obese person whose BMI is 30 or greater may be at 24% additional risk for cardiovascular event or premature death compared to a person of normal weight, says Dr. Retnakaran.

This is an important finding and if confirmed by further studies it should send a clear message that the healthy wraith means better health in general

One very important implication of this study is explained in this article: “The idea that we don’t need to target health care resources toward obese people whose lab tests are ‘normal’ turns out to be false" Reply

Some other interesting findigs: Increased risk is presented by poor metabolic status, regardless of weight – i.e., both overweight and obese individuals are at the same level of risk Reply

Obesity has become a world-wide epidemic. For the first time in human history, the number of overweight people rivals the number of underweight people Reply
