Grow Youthful: How to Slow Your Aging and Enjoy Extraordinary Health

It's not just how much excess fat you have, but where it's located

An extensive research study (1) links waist fat with early death. "The most important result of our study is the finding that not just being overweight, but also the distribution of body fat, affects the risk of premature death," says lead author Tobias Pischon from the German Institute of Human Nutrition.

Death risk increased with waist circumference, regardless of whether the participants were overweight or not. "Our study shows that accumulating excess fat around your middle can put your health at risk even if your weight is normal," he says. "There aren't many simple individual characteristics that can increase a person's risk of premature death to this extent, independent of smoking and drinking."

Researchers examined data on 359,387 European adults over a period of nearly ten years. This was one of the largest, longest health studies in the world - the ongoing European Prospective Investigation into Cancer and Nutrition (EPIC) health study. During the follow-up period, 14,723 of the study participants died.

Belly Fat is BAD

Excess belly fat has long been associated with an increased risk of heart disease, strokes and diabetes. However, more recent research also suggests a link between abdominal fat and a range of other diseases, including diabetes, some cancers and even age-related dementias.

University of Michigan cardiologist and research scientist Daniel Eitzman commented that belly fat (also known as visceral fat) produces more inflammation than fat found in other parts of the body. Inflammation likely plays a key role in heart disease and a host of other chronic diseases. He said that measurement of waist circumference or waist-to-hip ratio is important for assessing the risk of inflammation-driven diseases.

Pischon and his team used two measures of abdominal obesity - waist circumference and waist-to-hip ratio. They discovered that waist circumference and waist-to-hip measurements were a major health and early death predictor, even if you are not overweight. After adjusting for being overweight as measured by body mass index (BMI), they found that:

This finding should encourage doctors to measure patients' waists as well as their weight and BMI on routine visits. The approach to diet and exercise in Grow Youthful is ideal for reducing this type of fat and gaining many healthy years.

Test Yourself

The good news is that you don't need to spend any money or wait ages to test yourself. So how do you tell if you have excessive belly fat?

Says Riboli: "If you have a large waist, you probably need to increase the amount of exercise you do every day, avoid excessive alcohol consumption and improve your diet. This could make a huge difference in reducing your risk of an early death."
