Waist Size Predicts Heart Failure

The main reason people over 65 wind up in the hospital is heart failure, also known as "congestive heart failure". And the very best predictor of whether or not you're likely to get heart failure might surprise you.

It's waist size.

A new study published in the journal Circulation tracked data from two Swedish population based studies that together included 80,000 men and women aged 45-83. All participants filled in questionnaires about their height, weight, waist circumference and other vital statistics. They were then followed for seven years.

The researchers found- not surprisingly- that weight was linked to risk for heart failure. But they also found that even within the normal weight range (BMI 25 or less), those who had an extra 10cm (about 4 inches) on their waist had about 15% higher risk of heart failure. This went up to 18% for those who were heavier (BMI of 30 or more).

The researchers measured waist size, waist-to-hip ratio, waist-to-height ration and BMI (body mass index). All four measures were associated with heart disease, but waist circumference alone predicted heart disease risk regardless of other measures.

I've written before about the importance of waist size and of the waist-to-hip ratio. Nutritionists and smart doctors have long known that 35" for women and 40" for men represent a danger point for insulin resistance (which is the cornerstone of Metabolic Syndrome, also known as pre-diabetes). Metabolic Syndrome significantly increases the risk for heart disease.

If your waist is over 35" (women) or 40" (men) it's time to start doing something. I've found that a low-carb diet is one of the most effective ways to combat belly fat and reduce the size of your waist.
