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.

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.

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.
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.

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.

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.”
