Over 40% of American adults are obese. Nearly 1 in 10 are morbidly obese.

More than 4 in 10 Americans are now obese.

Key findings from the U.S. Centers for Disease Control and Prevention study »

  • In 2017–2018, the age-adjusted prevalence of obesity in adults was 42.4%, and there were no significant differences between men and women among all adults or by age group.
  • The age-adjusted prevalence of severe obesity in adults was 9.2% and was higher in women than in men.
  • Among adults, the prevalence of both obesity and severe obesity was highest in non-Hispanic black adults compared with other race and Hispanic-origin groups.
  • The prevalence of severe obesity was highest among adults aged 40–59 compared with other age groups.
  • From 1999–2000 through 2017–2018, the prevalence of both obesity and severe obesity increased among adults.

This research corresponds to earlier studies that suggest half of adult Americans will be obese within 10 years.

Nearly half of American adults will be obese within 10 years

Brian P. Dunleavy, UPI »

Researchers at T.H. Chan School of Public Health at Harvard University, who will have their findings published Wednesday in the New England Journal of Medicine, also suggest that more than half of the population in 29 U.S. states will be obese.

Currently, the analysis estimates that 40 percent of American adults are obese, with 18 percent severely so.

“Prevention is going to be key to better managing this epidemic” of obesity,” lead author Zachary Ward, programmer/analyst at Harvard’s Center for Health Decision Science, said in a press release.

Obesity is on track to overtake smoking as the single biggest cause of preventable cancer in British women

If the projected trends continue, obesity as a cause of cancer in women will overtake smoking by 2043, the report says.

The figures for men are different as men are more likely to smoke and to get tobacco-related cancers. The gap between obesity and smoking as causes of cancer is expected to close much later than in woman.

While more males than females are overweight, obesity has a greater effect on women as some of the most common obesity-related cancers predominantly affect them, such as breast and womb cancers.

Everything you ever wanted to know about artificial sweeteners, but were afraid to ask

A new study has reopened the debate on artificial sweeteners, and some are saying it might actually cause obesity, not prevent it.

Sugars activate our reward circuits—they give us a hit of feel-good neurochemicals that prompt us to continue craving them. The more sugar you eat, the more you want it.

Since artificial sweeteners don’t satisfy your brain the way real sugar does, though, you don’t sate the craving. You’ll keep hankering after sweet foods and will probably end up eating more calories overall. That adds up to more pounds than you would’ve gained just by eating that cupcake in the first place.

We’re in a new age of obesity. How did it happen?

The Guardian:

Yes, we ate more in 1976, but differently. Today, we buy half as much fresh milk per person, but five times more yoghurt, three times more ice cream and – wait for it – 39 times as many dairy desserts. We buy half as many eggs as in 1976, but a third more breakfast cereals and twice the cereal snacks; half the total potatoes, but three times the crisps. While our direct purchases of sugar have sharply declined, the sugar we consume in drinks and confectionery is likely to have rocketed (there are purchase numbers only from 1992, at which point they were rising rapidly. Perhaps, as we consumed just 9kcal a day in the form of drinks in 1976, no one thought the numbers were worth collecting.) In other words, the opportunities to load our food with sugar have boomed. As some experts have long proposed, this seems to be the issue.

The shift has not happened by accident.

The Unintended Consequences of LED Lighting

The blue light of modern LED’s is throwing our circadian rhythms out of whack.

This biological cycle regulates how our body functions and repairs itself, and not only includes sleep and wakefulness. Allowing our bodies to get out of sync can contribute to illness, obesity, diabetes, and an increased risk of cancer.

Medium:

The widespread use of high-energy visible (HEV) light may have mighty ambitions, but its ubiquity has enormous, unintended, and unforeseen consequences on human health, well-being, and culture.

Does this free trade agreement make me look fat? The hidden calorie cost of free trade

CBC:

A new analysis reveals that Canadians had access to about 170 extra calories per day after the first Canada-U.S. free trade agreement — a caloric boost attributed to an increase in highly processed food that flooded into Canada after U.S. trade barriers were removed.

That increase in available calories was estimated to be enough for some Canadians to gain as much as 27 pounds (12.2 kilograms) and could have contributed to rising obesity in Canada.

That’s the finding of the UK study that looked at the “natural experiment” created when Canada and the U.S. negotiated the original free trade deal in 1989 — a deal that became a prototype for the North American Free Trade Agreement (NAFTA) and other international trade negotiations.

American adults keep getting fatter

Matt Richtel and Andrew Jacobs, The New York Times:

The latest data from the National Health and Nutrition Examination Survey comes at a time when the food industry is pushing back against stronger public health measures aimed at combating obesity.

In recent NAFTA negotiations, the Trump administration has proposed rules favored by major food companies that would limit the ability of the United States, Mexico and Canada to require prominent labels on packaged foods warning about the health risks of foods high in sugar and fat.

While the latest survey data doesn’t explain why Americans continue to get heavier, nutritionists and other experts cite lifestyle, genetics, and, most importantly, a poor diet as factors. Fast food sales in the United States rose 22.7 percent from 2012 to 2017, according to Euromonitor, while packaged food sales rose 8.8 percent.

Ex-tech workers plead with Facebook to consider the harm they are doing to children

David Smith, The Guardian:

A gathering of Silicon Valley alumni and whistleblowers and Washington lobbyists in the US capital heard warnings of potential links between tech addiction and sleep disruption, poor academic performance, anxiety, depression, obesity, social isolation and suicide.

Conference organiser James Steyer, chief executive and founder of Common Sense Media, a not-for-profit promoting safe technology and media for children, criticised giants such as Facebook, Google and Twitter. He said: “Talk is cheap. Show me the money. Period.”

There were pleas for Mark Zuckerberg, the Facebook co-founder and chief executive, and Sheryl Sandberg, the company’s chief operating officer, to apply values they advocate for their own families. Steyer added: “Mark and Sheryl at Facebook are good people. They are parents too. They have to think about their own kids when making a big picture decision there.”
