- According to the CDC, obesity is costing the U.S. $147 billion each year in medical costs.
- The new Cornell study found that knowing calorie information helped diners eat less.
- Experts believe this could force chain restaurants to offer healthier, low-calorie options
Of all the dietary trends, superfood cleanses, high-intensity workouts, fad pills and powders, and metabolic superstar programs guaranteeing weight loss, one tried and true method continues to be a sound means for maintaining a healthy weight: reducing your calories.
A Cornell study, published in August, has discovered that restaurants that list calorie content help customers moderate the amount of food they consume — albeit, by a little. Still, a little can go a long way once you become accustomed to it.
The research team of John Cawley, Alex Susskind, and Barton Willage set up shop in two restaurants for a randomized field experiment. Two different groups were then told to order: a control group with normal menus and a treatment group, which read from menus featuring calorie information. By the end, 5,500 diners contributed to the study.
The treatment group ended up ordering 3 percent fewer calories than the control group — a result of 45 calories per meal. The biggest effect seems to be on consumer awareness. The researchers noted that customers were surprised by how many calories basic meals, such as a tomato soup/grilled cheese combo, has. They continue,
The findings come at a time when most Americans don't have a precise estimate of how many calories they're eating, because one-third of their food is prepared outside the home. At the same time, the obesity crisis in America has reached epidemic proportions; the prevalence of obesity in adults has nearly tripled in the past 50 years, to nearly 40 percent of the population in 2016.
This follows a law requiring chains with 20 or more locations to post calorie content on menus and menu boards, which went into effect earlier this year. The move was set to launch in 2011 as part of the Affordable Care Act's requirements, yet pushback from lobbying efforts delayed its implementation.
Part of the gripe from restaurant chains (especially pizza establishments) is that it will reduce profits. Yet in the Cornell study researchers found no evidence of monetary loss between the groups. In fact, healthier options often cost more than junk food. That said, patrons realizing which restaurants are not healthy could have a ripple effect. Though the Cornell study is an outlier — other studies have found that the calorie content does not change minds — it might be pushing restaurants to offer more low-calorie options.

The cost to restaurants does not nearly equate to those on our medical infrastructure. According to the CDC, obesity is costing the U.S. $147 billion each year. This involves direct and indirect medical problems related to being overweight, including cardiovascular disease, type 2 diabetes, immune system-related problems, and many other ailments.
John Cawley, a professor of policy analysis and management in the College of Human Ecology at Cornell, views the calorie listing on menus as an easy to implement solution.
It's a cheap policy to put in place, and the fact that there is a reduction in calories ordered makes it appealing.
While not the only solution, it's a step in the right direction. Awareness is a catalyst for change, and one thing is certain: we can't keep heading blindly in the direction we've been going. The consumption of unhealthy high-calorie foods, beginning with the frozen dinner revolution of post-World War II America right up through pumpkin spice lattes, has made us a sick and diseased nation. Every calorie counts.

How New York's largest hospital system is predicting COVID-19 spikes
Northwell Health is using insights from website traffic to forecast COVID-19 hospitalizations two weeks in the future.
- The machine-learning algorithm works by analyzing the online behavior of visitors to the Northwell Health website and comparing that data to future COVID-19 hospitalizations.
- The tool, which uses anonymized data, has so far predicted hospitalizations with an accuracy rate of 80 percent.
- Machine-learning tools are helping health-care professionals worldwide better constrain and treat COVID-19.
The value of forecasting

<p>One unique benefit of forecasting COVID-19 hospitalizations is that it allows health systems to better prepare, manage and allocate resources. For example, if the tool forecasted a surge in COVID-19 hospitalizations in two weeks, Northwell Health could begin:</p><ul><li>Making space for an influx of patients</li><li>Moving personal protective equipment to where it's most needed</li><li>Strategically allocating staff during the predicted surge</li><li>Increasing the number of tests offered to asymptomatic patients</li></ul><p>The health-care field is increasingly using machine learning. It's already helping doctors develop <a href="https://care.diabetesjournals.org/content/early/2020/06/09/dc19-1870" target="_blank">personalized care plans for diabetes patients</a>, improving cancer screening techniques, and enabling mental health professionals to better predict which patients are at <a href="https://healthitanalytics.com/news/ehr-data-fuels-accurate-predictive-analytics-for-suicide-risk" target="_blank" rel="noopener noreferrer">elevated risk of suicide</a>, to name a few applications.</p><p>Health systems around the world have already begun exploring how <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7315944/" target="_blank" rel="noopener noreferrer">machine learning can help battle the pandemic</a>, including better COVID-19 screening, diagnosis, contact tracing, and drug and vaccine development.</p><p>Cruzen said these kinds of tools represent a shift in how health systems can tackle a wide variety of problems.</p><p>"Health care has always used the past to predict the future, but not in this mathematical way," Cruzen said. "I think [Northwell Health's new predictive tool] really is a great first example of how we should be attacking a lot of things as we go forward."</p>Making machine-learning tools openly accessible
<p>Northwell Health has made its predictive tool <a href="https://github.com/northwell-health/covid-web-data-predictor" target="_blank">available for free</a> to any health system that wishes to utilize it.</p><p>"COVID is everybody's problem, and I think developing tools that can be used to help others is sort of why people go into health care," Dr. Cruzen said. "It was really consistent with our mission."</p><p>Open collaboration is something the world's governments and health systems should be striving for during the pandemic, said Michael Dowling, Northwell Health's president and CEO.</p><p>"Whenever you develop anything and somebody else gets it, they improve it and they continue to make it better," Dowling said. "As a country, we lack data. I believe very, very strongly that we should have been and should be now working with other countries, including China, including the European Union, including England and others to figure out how to develop a health surveillance system so you can anticipate way in advance when these things are going to occur."</p><p>In all, Northwell Health has treated more than 112,000 COVID patients. During the pandemic, Dowling said he's seen an outpouring of goodwill, collaboration, and sacrifice from the community and the tens of thousands of staff who work across Northwell.</p><p>"COVID has changed our perspective on everything—and not just those of us in health care, because it has disrupted everybody's life," Dowling said. "It has demonstrated the value of community, how we help one another."</p>3,000-pound Triceratops skull unearthed in South Dakota
"You dream about these kinds of moments when you're a kid," said lead paleontologist David Schmidt.
Excavation of a triceratops skull in South Dakota.
- The triceratops skull was first discovered in 2019, but was excavated over the summer of 2020.
- It was discovered in the South Dakota Badlands, an area where the Triceratops roamed some 66 million years ago.
- Studying dinosaurs helps scientists better understand the evolution of all life on Earth.

<p style="margin-left: 20px;">"We had to be really careful," Schmidt told St. Louis Public Radio. "We couldn't disturb anything at all, because at that point, it was under law enforcement investigation. They were telling us, 'Don't even make footprints,' and I was thinking, 'How are we supposed to do that?'"</p><p>Another difficulty was the mammoth size of the skull: about 7 feet long and more than 3,000 pounds. (For context, the largest triceratops skull ever unearthed was about <a href="https://www.tandfonline.com/doi/abs/10.1080/02724634.2010.483632" target="_blank">8.2 feet long</a>.) The skull of Schmidt's dinosaur was likely a <em>Triceratops prorsus, </em>one of two species of triceratops that roamed what's now North America about 66 million years ago.</p>Credit: David Schmidt / Westminster College
<p>The triceratops was an herbivore, but it was also a favorite meal of the T<em>yrannosaurus rex</em>. That probably explains why the Dakotas contain many scattered triceratops bone fragments, and, less commonly, complete bones and skulls. In summer 2019, for example, a separate team on a dig in North Dakota made <a href="https://www.nytimes.com/2019/07/26/science/triceratops-skull-65-million-years-old.html" target="_blank">headlines</a> after unearthing a complete triceratops skull that measured five feet in length.</p><p>Michael Kjelland, a biology professor who participated in that excavation, said digging up the dinosaur was like completing a "multi-piece, 3-D jigsaw puzzle" that required "engineering that rivaled SpaceX," he jokingly told the <a href="https://www.nytimes.com/2019/07/26/science/triceratops-skull-65-million-years-old.html" target="_blank">New York Times</a>.</p>Morrison Formation in Colorado
