Overweight Statistics

Many things have changed since 1960. Back then the price of gas was 25 cents, house price $12,700, loaf of bread 25 cents, and a pound of hamburger 45 cents. Not so with the CDC definitions of weight. The tables used to determine the current obesity levels are still the same ones used during 1960.

Unrelated, but interesting to note that since 1960, the average weight of a turkey has more than doubled from 15.1 pounds during 1960 to 31.1 pounds during 2017.

According to the US Centers for Disease Control and the US National Center for Health Statistics, as of 2014, close to 71% of US adults age 20 or older are overweight or obese, based on those old tables.

While the world has changed dramatically, the weight definitions for overweight and obese have not changed during the past almost sixty years. The fact that Americans have also increased height and age during that time is not taken into consideration of the weight calculations.

Bottom line, we are comparing current weights to ancient 1960 tables. Also, BMI, as a measure has been debunked by the same CDC which states, "BMI ranges are not exact ranges of healthy and unhealthy weight." According to the BMI table, Dwayne 'The Rock' Johnson and Vin Diesel are both overweight.

Maybe the 1960 definitions and the BMI definitions need to be updated according to modern reality. Since we have achieved two standard deviations above the almost 60 year old tables, it might be time to redefine normal or we will soon be 100% overweight. Then the government agencies will forced to redefine the definition of windmills, as they are wont to do.

Overweight Defined

During 1998, twenty nine million Americans suddenly became overweight without gaining an ounce. The US government announced new guidelines lowering the threshold of what classifies a person as overweight.

Previously, if your body mass index (BMI) was less than 28 for men or 27 for women, you were considered 'normal'. Since then only BMIs of 25 or below are considered healthy. That was a reduction of about 20 pounds for the average male. BMI is a ratio of weight to height, and is considered an indicator of how much body fat a person has.

Overweight is Good For You

Moderately overweight elderly people may live longer than those of normal weight, an Australian study suggests, but being very overweight or being underweight shortened lives.

The study of 9,200 over-70s found that regardless of weight, sedentary lifestyles shortened lives, particularly for women.
The report, published in the Journal of the American Geriatric Society, said dieting may not be beneficial in this age group.

The team tracked the number of deaths over 10 years among volunteers who were aged 70 - 75 at the start of the study. It found that those with a BMI which classed them as overweight not only had the lowest overall risk of dying, they also had the lowest risk of dying from specific diseases, such as cardiovascular disease, cancer, and chronic respiratory disease.

Overall death rate among the obese group was similar to that among those of normal weight, but those who were very obese had a greater risk of dying during the 10 year period.

The conclusion of this study is that being overweight may be less harmful for elderly people and it corroborates the findings of previous research.

However, sedentary lifestyles shortened lives across all weight groups, doubling the risk of mortality for women over the period studied, and increasing it by 25% for men. I think I need to go fix a bacon, bacon, bacon and cheese sandwich with potato chips on the side.
