Impaired relaxation of blood vessels is associated with being overweight or obese and is considered part of the mechanism by which excess weight contributes to cardiovascular risk: the risk of high blood pressure, heart attack or stroke. A study published in the journal Obesity (August, 2010) showed that regular aerobic exercise (for only three months!) improved blood vessel relaxation even without weight loss. Other studies have shown that dietary weight loss without exercise also improved blood vessel relaxation.
Such studies remind us that there is more than one way to achieve a healthy lifestyle. Practical Health Strategies helps you find the one that works for you.
A study published in the journal Obesity evaluated the individual and aggregate years-of-life-lost (YLL) associated with being overweight or obese. The good news for many of us is that they found that being overweight or mildly obese was not statistically associated with a reduction in life expectancy. This means only that the effect was small compared to other factors. The bad news is that higher levels of obesity are associated with a lower expected life expectancy. Higher levels of obesity are responsible for approximately 95 million YLL. White females accounted for more than two-thirds of the YLL.

A study published in the journal Obesity, investigated whether insulin resistance was a necessary precursor of weight gain induced by eight weeks of overeating in adults. There was a wide range of insulin sensitivity measured in the subjects at baseline and baseline insulin sensitivity level was not predictive of fat gain from overeating. This suggests that the insulin resistance found in obesity is more likely the result of the obesity than the cause of the obesity. Other studies have shown that exercise and physical activity increase insulin sensitivity even in obese subjects.
