The Benefits of Calorie Restriction
Dr. Robert N. Butler is the President and CEO of the International Longevity Center. Whether through his many appearances in front of the United States Congress, or his hundreds of interviews with the media, Dr. Butler has worked tirelessly for decades to push population-aging issues into the public discourse. As a gerontologist and psychiatrist, Dr. Butler recognized discrimination against the elderly as early as 1968, coining the term "ageism." Eight years later, the publication of his Pulitzer-prize-winning "Why Survive? Being Old in America" solidified his reputation as someone who foresaw the impact that aging would have on American society. A founding director of the National Institute on Aging of the National Institutes of Health, as well as the nation's first department of geriatrics at Mount Sinai School of Medicine, Dr. Butler often consults for television and radio. He is the author of some 300 scientific and medical articles. Source: The International Longevity Center
Question: Does calorie restriction slow aging?
Robert Butler: There is a lot of truth to that. It applies to almost every species in which it has been studied and it is now a process being studied in monkeys, which are the closest we have from an evolutionary point of view, a group that is being studied. So, far it looks like they are doing better and staying healthier under caloric restriction. We don't know yet about the length of life because we haven't had the study going on that long, but it was justified to now start studying it in human beings and so there are three universities where caloric restriction is being studied in human beings.
Question: Why is restriction effective?
Robert Butler: Well, too many calories, I mean there is an appropriate number of calories, but too many calories add obesity and America is the heaviest nation in the world. Definitely, it is a disaster. In fact, we are now seeing type 2, which means old age diabetes in 10 year old children and that means they are going to have more coronary heart disease, more diabetes, more arthritis and they are going to die younger. It could be first generation that actually lives less long than their parents.
Question: Are there any other benefits?
Robert Butler: Well, you feel stronger and better. We of course know that the caloric restricted diet is going to be very unpalatable for most people. There is too much of a restriction. So, what is now being studied are the ingredients. Why it happens? And if we can put that into a medicine, we would therefore be able to sort of speak have our cake and eat it too and there is a chemical called resveratrol and a series of genes called SIRT1s, which may account for caloric restriction and if so, that is a very important step forward in understanding the basic biology of aging and longevity.
Question: Are there any negative side effects?
Robert Butler: Well, they do have less sexual libido. They may not feel as energetic because they are not getting as much food. Other than that, we don’t know of any truly serious consequences, but as I said it would be much better if we could find the appropriate pharmacological agent or drug that would do the job of caloric restriction without the more unpleasant aspects like having such a restricted diet.

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.

Building a personal connection with students can counteract some negative side effects of remote learning.
- Not being able to engage with students in-person due to the pandemic has presented several new challenges for educators, both technical and social. Digital tools have changed the way we all think about learning, but George Couros argues that more needs to be done to make up for what has been lost during "emergency remote teaching."
- One interesting way he has seen to bridge that gap and strengthen teacher-student and student-student relationships is through an event called Identity Day. Giving students the opportunity to share something they are passionate about makes them feel more connected and gets them involved in their education.
- "My hope is that we take these skills and these abilities we're developing through this process and we actually become so much better for our kids when we get back to our face-to-face setting," Couros says. He adds that while no one can predict the future, we can all do our part to adapt to it.
