June 19, 2022 by Sarah Barkley

Everyone experiences the feeling of defeat occasionally in life. It’s normal, but you can’t dwell in that mindset forever without losing hope. These hope quotes can help you when you feel defeated, allowing you to keep pushing forward.

When you feel defeated, you likely want to give up. You might feel like you lost something, your energy drains, you’re helpless, and you aren’t eager to do anything productive. While it’s hard to experience defeat, you must pull yourself out of it and keep moving forward.

Using quotes about hope can help you overcome feelings of despair and defeat. You might feel helpless at the moment, but you’ll quickly regain your strength and confidence. These hope quotes will give you the guidance and encouragement you need to overcome.

Hope Quotes to Read When You Feel Defeated

1. “Setbacks in life are opportunities to perform at a new level.” – William Cranch Bond

Even when you feel fully prepared for something, you might still experience setbacks. Don’t let the setbacks make you feel defeated because you can overcome anything that happens. As Bond explains, setbacks give you the chance to take your abilities to a new level.

2. “Hope is important because it can make the present moment less difficult to bear. If we believe that tomorrow will be better we can bear a hardship today.” – Thich Nhat Hahn

When everything seems to be going wrong, remain hopeful because it’ll make the situation easier. You can get through hard times when you stay hopeful, and it’ll help you overcome feelings of defeat.

3. “He knows not his own strength who hath not met adversity.” – William Samuel Johnson

You must go through hard times and setbacks if you want to learn how strong you are. Without adversity, you’ll never know what you are capable of handling. When you recognize that setbacks or obstacles help you develop, you’ll overcome the feeling of defeat.

4. “The defeat in your head is not the same as the defeat in your heart. If your head tells you to stop, try listening to your heart.” – Unknown

If your negative thoughts contribute to your feeling of defeat, then stop listening to your head. Instead, listen to your heart and follow your path. Keep pushing through and listening for thoughts or feelings that motivate and encourage you.

Gain Strength with These Encouraging Words

5. “You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, ‘I lived through this horror. I can take the next thing that comes along.’” – Eleanor Roosevelt

When you experience fear, it might be easy to give in to defeat and stop trying. However, if you can push through, you gain so much more than if you stopped. Plus, you can look back once the situation is over and see the strength that you exhibited.

6. “Never confuse a single defeat with a final defeat.” – F. Scott Fitzgerald

If you ever fail at something, remember that it doesn’t mean everything is over. You can try again as many times as you want, so there is never a final defeat unless you decide there is. Remember this hopeful quote the next time you feel like you’ve failed because there is always another chance for you.

7. “We can design our life agendas so that our daily planner is no longer the object of resentment but, rather, a thing of beauty: a stunning log of our enjoyment of life and progress toward freedom and transcendence.” – Brendon Burchard

If your to-do list makes you feel defeated, then this is one of the best quotes about hope for you to read. While you can’t always change what you must do, you can adjust how you think about it.

Stop resenting your responsibilities and learn to embrace them. Each task you complete can bring a little joy to your life if you view it as progress and betterment.

8. “Being defeated is often a temporary condition. Giving up is what makes it permanent.” – Marilyn vos Savant

The way you feel right now is temporary. If you feel defeated, it’ll pass if you keep trying and giving your best effort.

The Wisdom of Learning Life Lessons

9. “You learn more from losing than winning. You learn how to keep going.” – Morgan Wootten

When you win, it doesn’t always include a learning opportunity. However, losing always allows you to learn something from it. As Wootten explains, you learn how to keep going, but you also learn much more.

10. “I will love the light for it shows me the way, yet I will endure the darkness for it shows me the stars.” – Og Mandino

While happiness and success are always preferred, darkness plays an essential role, too. Without hard times, you would never enjoy the brighter moments shining through. Remember to look for the stars on your darkest days so that you can find the light once again.

11. “We all want things to stay the same. Settle for living in misery because we are afraid of change, of things crumbling to ruins. Ruin is a gift. Ruin is the road to transformation.” – Elizabeth Gilbert

If you are afraid of change, you might stay in a situation that makes you feel defeated. Rather than continue feeling defeated and miserable, make the necessary changes to improve your life.

You might feel like everything you worked for crumbles, but it’s better than never moving forward. Starting over can transform your life and bring joy to your soul once again. Use this quote as a reminder to always stay hopeful because you can make a change at any moment.

Hope Quotes About Beating Adversity

12. “Sometimes adversity is what you need to face in order to become successful.” – Zig Ziglar

If you never experience adversity, you won’t grow, learn, or develop. You must face challenges if you want to reach success. The challenges push you to try harder and do better.

13. “Nobody trips over mountains. It is the small pebble that causes you to stumble. Pass all the pebbles in your path, and you will find you have crossed the mountain.” – Unknown

When you look at what lies ahead of you, remember that the mountain isn’t the hard part. The hard part is found in the smaller moments each day. If you can overcome and get through the hard parts, you’ll find that you make it to the other side.

14. “You may encounter many defeats, but you must not be defeated. In fact, it may be necessary to encounter the defeats, so you can know who you are, what you can rise from, how you can still come out of it.” – Maya Angelou

When you encounter defeats, don’t let the feeling take over your life. Instead, use it as an opportunity to learn more about who you are and what you can do.

15. “Don’t let the fear of the time it will take to accomplish something stand in the way of your doing it. The time will pass anyway; we might just as well put that passing time to the best possible use.” – Earl Nightingale

When you think of the amount of time it’ll take you to accomplish something, it might make you feel defeated. Don’t let it stop you from getting started, though. Push away the feeling of defeat because time passes no matter what you choose to do. It’s never too late to start, so put the time to good use and start working toward your goals right away.

Fight Back from Your Losses

16. “True defeat only happens if you stop. If you never stop, you’re never truly defeated.” – Unknown

When things don’t work out right away, you aren’t defeated unless you give up. You can learn from each mistake, developing your skills as you figure out what doesn’t work. Remember this hope quote the next time you feel defeated so that you can keep moving forward.

17. “Don’t dwell on what went wrong. Instead, focus on what to do next. Spend your energies on moving forward toward finding the answer.” – Denis Waitley

When something doesn’t go as planned, don’t dwell on the mistakes that you made. Dwelling won’t give you hope, but focusing on the next step to take will.

18. “The brick walls are there for a reason. The brick walls are not there to keep us out, the brick walls are there to give us a chance to show how badly we want something. Because the brick walls are there to stop the people who don’t want it badly enough. They’re there to stop the other people.” – Randy Pausch

You’ll encounter obstacles in your life, but they aren’t there to force you to stop. The challenges are there to encourage you to find another way and to work hard.

19. “Most of the important things in the world have been accomplished by people who have kept on trying when there seemed to be no hope at all.” – Dale Carnegie

When you feel defeated, remember this hope quote. Even the most successful people fail sometimes, but that doesn’t mean there’s no hope left.

20. “Just don’t give up trying to do what you really want to do. When there is love and inspiration, I don’t think you can go wrong.” – Ella Fitzgerald

No matter what happens in your life, don’t give up on your dreams. Keep working toward your goals, and focus on love and inspiration.

When you feel defeated, remember these hope quotes to help you get through. If you can see better days ahead, your well-being will begin to improve right now.

Keep pushing through no matter how hard things get, as these hope quotes encourage. When you get through the challenging time, you’ll look back and realize your hopefulness was all worthwhile.

Scientist Explains How to Manage the Climate Tipping Point

June 19, 2022 by Kristen Lawrence

Scientists have sounded the alarm about a climate tipping point for decades. Previously, they believed that once the climate passed a certain threshold, it would lead to catastrophic, irreversible changes.

However, a new study by scientists from Utrecht University found that maybe we underestimated the climate’s resilience. While there’s overwhelming evidence of climate change, their research suggests that reaching tipping points won’t immediately send the planet into chaos.

What Does the Term Climate Tipping Point Mean?

About 20 years ago, the Intergovernmental Panel on Climate Change (IPCC) introduced the concept of tipping points. They identified nine key tipping points in the Earth system that could lead to abrupt changes in the climate. The IPCC initially believed that these large-scale climate shifts would only occur if warming exceeding 5 degrees C above pre-industrial levels. However, they’ve confirmed that even a temperature increase of 1-2 degrees C could trigger these tipping points.

Nine global climate tipping points

Amazon rainforest
Arctic sea ice
Atlantic meridional overturning circulation (AMOC)
Boreal forest
Coral reefs
Greenland ice sheet
Permafrost
West Antarctic ice sheet
Wilkes Basin

In our interconnected, highly complex Earth system, passing just one of these thresholds could destabilize every climate tipping point. For example, scientists have found that melting ice in the Arctic amplifies regional warming. With less ice reflecting the Sun’s rays back into the atmosphere, the radiation remains on Earth. As ice continues to melt, the influx of freshwater flows into the North Atlantic.

Climate scientists believe that melting sea ice contributed to a 15% slowdown of the AMOC since 1950. This critical system of currents distributes heat and salt throughout the oceans. However, the rapid melting of ice sheets and the continual weakening of the AMOC could destabilize the West African monsoon.

This would cause droughts in Africa’s Sahel region and the Amazon. In addition, slowing of the AMOC would disrupt the East Asian monsoon, causing extreme heating in the Southern Ocean, accelerating Antarctic ice loss. As you can see, crossing just one of the climate tipping points could cause cascading effects throughout the climate.

But New Research Shows We Could Avoid the Climate Tipping Point

Luckily, our fate isn’t sealed by a changing climate after all. The new study published in the journal Science finds that warning signs from the environment may point to its resilience. An international team of ecologists and mathematicians studied these climate tipping points and made an unexpected discovery.

“Yes, we need to do everything we can to stop climate change,” the authors said in complete agreement with the recent IPCC report. “But the Earth is much more resilient than previously thought. The concept of tipping points is too simple.”

The paper builds on decades of collaborations between various research institutes in the Netherlands and other countries. The researchers wanted to investigate the idea of tipping points within spatial patterns.

“The formation of spatial patterns in ecosystems, like the spontaneous formation of complex vegetation patterns, is often explained as an early-warning signal for a critical transition,” explains lead author Max Rietkerk, ecologist affiliated with Utrecht University. “But these patterns actually appear to allow ecosystems to evade such tipping points.”

They based these conclusions on mathematical models of spatial patterns and observations from living ecosystems.

Maybe These Models Should Be Named, “Turing Patterns,” Instead

In nature, the sudden appearance of spatial patterns is called “Turing patterns,” named after the British mathematician Alan Turing. Turing explained in 1952 how patterns in nature, like stripes on zebras, can develop from stable conditions. Perhaps this is a better description than the term climate tipping point.

“In ecological science, the Turing patterns are often explained as early-warning signals because they indicate disturbance,” says Leiden University mathematician and co-author Arjen Doelman. “Turing’s mechanism of pattern formation is still undisputed. But the fact that a pattern is forming somewhere does not necessarily mean that an equilibrium is disrupted beyond a tipping point.”

Rietkerk refers to the transition from savanna to desert as an example of Turing patterns. “There you can observe all sorts of complex spatial forms. It’s a spatial reorganization but not necessarily a tipping point. On the contrary: those Turing patterns are actually a sign of resilience.”

The Complexity of Earth’s System May Shield Us from Climate Change

This doesn’t mean we should give up tackling pressing matters such as pollution, biodiversity loss, or rising sea levels. It simply means that Earth’s complexity may benefit us when it comes to climate change. In their research, the team discovered a fascinating phenomenon called multistability, providing further evidence of the planet’s resilience.

The climate tipping point concept suggests that a plethora of spatial patterns can exist simultaneously under similar scenarios. Rietkerk explains that “each of these patterns can remain stable under a wide range of conditions and climate change. Moreover, we found that any complex system large enough to generate spatial patterns may also evade tipping points.”

Now, the scientists must answer this critical question: which systems are more vulnerable to tipping, and which are more resilient?

“That means we have to go back to the drawing table to understand the exact role of tipping points,” Rietkerk says. “Only then can we determine which conditions and spatial patterns result in tipping points, and which ones do not.”

This work contributes to the TiPES project, an EU Horizon 2020 interdisciplinary climate science project between 18 partner institutions in 10 European countries on Earth’s tipping points.

Final Thoughts on How Passing Climate Tipping Points May Not Lead to Our Demise After All

In a new study, scientists found that reaching a climate tipping point may not lead to immediate disaster. The research revealed the resilience of Earth’s climate system, capable of adapting to large-scale changes. They used the example of Turing patterns in nature to provide evidence for their theory. Basically, they say that these spatial patterns reveal a reorganization of a system rather than a disruption.

So, perhaps we will have to adapt to a changing climate, but that doesn’t mean we won’t survive. This study provides a comforting reminder that nature changes constantly. Sure, we’ll have to adjust to the new conditions, but that’s what humans have done throughout history, after all.

Study Reveals Small Dietary Changes to Help Live Longer

June 19, 2022 by Kristen Lawrence

Making small dietary changes could have a significant impact on your health, according to a new study. For example, researchers found that eating a hot dog could shorten your life by 36 minutes. On the other hand, eating a serving of nuts could extend your life by 26 minutes. It may not sound like much, but healthy eating can make a massive difference over months or years.

The University of Michigan study was published in the journal Nature Food on August 18, 2021. The study evaluated 5,853 foods, ranking them by their nutritional disease burden and their environmental impact. Researchers developed the Health Nutritional Index to quantify health effects in minutes of life gained or lost. The foods evaluated ranged from 74 minutes lost to 80 minutes of life gained per serving.

The study authors found that eating 10% fewer daily calories from beef and processed meats had significant health and environmental benefits. Substituting these foods for fruits, vegetables, nuts, legumes, and certain seafood resulted in a 33% reduction in dietary carbon footprint. It also could offer 48 minutes of healthy life gained per day.

Small dietary changes can enhance your life.

“Generally, dietary recommendations lack specific and actionable direction to motivate people to change their behavior, and rarely do dietary recommendations address environmental impacts,” said Katerina Stylianou, who performed the research as a doctoral candidate and postdoctoral fellow in the Department of Environmental Health Sciences at U-M’s School of Public Health. She now works as the Director of Public Health Information and Data Strategy at the Detroit Health Department.

First, researchers measured dietary impact on human health

The foundation of this study comes from the Health Nutritional Index, a new epidemiology-based nutritional index. Investigators collaborated with nutritionist Victor Fulgoni III from Nutrition Impact LLC to develop it. HENI calculates the net positive or adverse health effects in minutes of life gained or lost per serving of food consumed.

The index was adapted from the Global Burden of Disease, a compilation of data on hundreds of diseases and risk factors. The HENI index gathered data from this resource on disease mortality and morbidity caused by single food choices. Researchers used fifteen dietary risk factors and disease burden estimates from the GBD.

Next, they combined this data with nutrition profiles of foods consumed in the US.

They utilized the What We Eat in America National Health and Nutrition Examination Survey database for this step. Foods with positive scores increase longevity, while foods with negative scores decrease it.

Then they determined how these foods affected the environment

To understand the environmental impact of foods, the researchers used IMPACT World+. This method evaluates the effect of foods throughout their life cycle, from production to disposal. The team added updated assessments for water use and human health risks from fine particulate matter formation.

Next, the researchers developed a scoring method for eighteen environmental indicators which considered detailed food recipes in addition to estimated food waste. The team organized foods into three color zones: green, yellow, and red for the final step. After taking into account their nutritional and environmental impacts, researchers assigned the foods a color.

Foods in the green zone are beneficial to humans and the planet, having high nutritional value and low environmental impacts. Most foods in this zone include nuts, fruits, field-grown vegetables, legumes, whole grains, and seafood.

On the other hand, red zone foods include those that have detrimental nutritional and environmental impacts. The research team discovered that the highest negative nutritional impacts came from processed meats. Beef, pork, lamb, and processed meats caused the most significant burden on the environment. Because of their large carbon footprint and dangers to health, researchers suggest making dietary changes to reduce or avoid these foods.

However, researchers added that the range of environmental and health indicators varies greatly. They also acknowledge that nutritionally viable foods may not always leave a small carbon footprint and vice versa.

“Previous studies have often reduced their findings to a plant vs. animal-based foods discussion,” Stylianou said. “Although we find that plant-based foods generally perform better, there are considerable variations within both plant-based and animal-based foods.”

Based on the research, the team suggests making these small dietary changes:

Reduce or eliminate foods with the most negative health and environmental impacts, such as highly processed meat, beef, and shrimp, followed by pork, lamb, and greenhouse-grown vegetables.
Consume more of the most nutritionally healthy foods, including field-grown fruits and vegetables, legumes, nuts, and sustainably sourced seafood

“The urgency of dietary changes to improve human health and the environment is clear,” said Olivier Jolliet, U-M professor of environmental health science and senior author of the paper. “Our findings demonstrate that small targeted substitutions offer a feasible and powerful strategy to achieve significant health and environmental benefits without requiring dramatic dietary shifts.”

The research received funding from an unrestricted grant from the National Dairy Council and the University of Michigan Dow Sustainability Fellowship. Researchers collaborate with partners in Switzerland, Brazil, and Singapore to develop similar evaluation methods there. The team says that they hope to expand the system to all countries in the world in the future.

Perhaps then we’ll have an epidemic of health and start living in balance with nature. One can only hope, at least.

Final thoughts on the study that reveals small dietary changes can improve your life.

Frequently, people avoid making dietary changes because it seems overwhelming. However, becoming healthier doesn’t have to mean overhauling your whole lifestyle and eating habits. You can make minor improvements to your diet each day, such as eating a serving of nuts instead of a hot dog.

The study above reveals that making this one change can add nearly 30 minutes to your life. Now, imagine doing that dozens or hundreds of times, and you can perhaps extend your life by a few years. Everyone wants to know how to live longer, and now, the cat’s out of the bag.

Eat less meat and more fruits and veggies, and you’ll get to enjoy a few more sunrises. Plus, you’ll be doing the environment a huge favor while you’re at it.

Study Explains How We Can Harvest Precious Minerals from Asteroids

June 18, 2022 by Kristen Lawrence

A new study by University of Arizona researchers reveals that near-Earth asteroids could contain precious minerals. The iron, cobalt, and nickel present in these asteroids may provide an opportunity to mine them for use on Earth or in space. In their research, the UA team discovered more information about the origins and compositions of these mysterious asteroids.

The research analyzed two metal-rich near-Earth asteroids, or NEAs called 1986 DA and 2016 ED85. The scientists wanted to learn more about what metals they contained and their similarities to meteorites on Earth. The study was published in the Planetary Science Journal.

Scientists believe that the metal-rich NEAs formed during the destruction of developing planets in the solar system’s early history. However, before this study, researchers knew little else about rare asteroids. A team of students co-led by University of Arizona planetary science associate professor Vishnu Reddy studied the two asteroids named above.

They found that their spectral signatures closely resembled asteroid 16 Psyche, the largest metal-rich asteroid in our solar system. Located in the central asteroid belt between the orbits of Mars and Jupiter, scientists first discovered Psyche in 1852. Scientists speculate that Psyche may be the exposed core of a protoplanet – a small celestial body that never reached maturity.

Composed of iron and nickel, scientists believe the asteroid could have incredible treasures worth about $10,000 quadrillion. The possible wealth generated by the asteroid eclipses our global economy – worth $142 trillion – by orders of magnitude.

NASA plans to visit 16 Psyche in 2026 to learn more about its composition and magnetic field. It will mark the first mission to investigate a metallic asteroid rather than a rocky or icy one. Until they launch their mission, scientists believe the two “mini Psyches” could hold vital clues about these metal-rich asteroids.

Study Explains How Near-Earth Asteroids Could Contain Valuable Minerals

“Our analysis shows that both NEAs have surfaces with 85% metal such as iron and nickel and 15% silicate material, which is basically rock,” said lead author Juan Sanchez, who is based at the Planetary Science Institute. “These asteroids are similar to some stony-iron meteorites such as mesosiderites found on Earth.”

Astronomers have been fascinated with Psyche and similar asteroids for decades. By studying near-Earth metal-rich asteroids, they aim to identify meteorites that bear a striking resemblance to Psyche. The two near-Earth asteroids identified in the study measure about a mile across.

“We started a compositional survey of the NEA population in 2005, when I was a graduate student, intending to identify and characterize rare NEAs such as these metal-rich asteroids,” said Reddy, principal investigator of the NASA grant that funded the work. “It is rewarding that we have discovered these ‘mini Psyches’ so close to the Earth.”

“For perspective, a 50-meter (164-foot) metallic object similar to the two asteroids we studied created the Meteor Crater in Arizona,” said Adam Battle, a co-author of the paper along with fellow Lunar and Planetary Laboratory graduate students Benjamin Sharkey and Theodore Kareta. David Cantillo, an undergraduate student in the Department of Geosciences, also contributed to the research.

The Potential of Harvesting These Rare Metals and Minerals

The paper also investigated the potential of mining minerals on 1986 DA. It found that the asteroid’s iron, nickel, and cobalt would surpass Earth’s reserves of these rare metals. In fact, scientists estimate that the asteroid may contain a staggering $11.65 trillion worth of minerals. While this pales in comparison to 16 Psyche’s treasure trove, the materials could still prove helpful on Earth or other planets.

The idea of space mining has captured the attention of scientists worldwide because of the potential to colonize other planets. Not only would this expand our understanding of space, but it could also lessen our burden on Earth. By mining minerals from the asteroids, it would also eliminate expensive shuttle trips from Earth to space. Colonizing other planets probably won’t happen in the near future, but it’s an exciting possibility.

The Asteroids Likely Originated in the Same Asteroid Belt as 16 Psyche

When an asteroid gets demolished, it produces an asteroid family – a small cluster of asteroids with similar compositions and orbits. The research team analyzed the compositions and orbital pattern of both 1986 DA and 2016 ED85. In doing this, they determine four potential asteroid families in the outer area of the main asteroid belt.

The largest cluster of small bodies in the inner portion of the solar system resides here. In addition, most of the most significant identified metallic asteroids to date, including 16 Psyche, call this area of outer space home. The asteroid belt is located about 235 million to 309 million miles from the sun.

“We believe that these two ‘mini Psyches’ are probably fragments from a giant metallic asteroid in the main belt, but not 16 Psyche itself,” Cantillo said. “It’s possible that some of the iron and stony-iron meteorites found on Earth could have also come from that region in the solar system too.”

Scientists based their findings on observations from the NASA Infrared Telescope Facility in Hawaii. The NASA Near-Earth Object Observations Program, which also funds the NASA Infrared Telescope Facility, supported the study.

More studies are necessary in the future to determine the exact origins and value of these asteroids. However, the research marks a giant leap forward for humankind.

Final Thoughts: Near-Earth Asteroids Contain Rare Metals Worth Nearly $12 Trillion

As our global population continues to rise, our demand for resources keeps growing as well. We’ll likely have to turn to outer space to mine minerals for raw materials in the future. Luckily, scientists have discovered two near-Earth asteroids that contain vast amounts of iron, cobalt, and nickel. They estimate that the metal reserves on these formations greatly surpass that of Earth.

NASA plans to launch a mission to the largest metal-rich asteroid in our solar system, 16 Psyche, in 2022. They hope to learn more about the composition of this massive asteroid, valued at an estimated $10,000 quadrillion. Until then, this study on the two near-Earth asteroids provides excellent insight into the vast resources in our cosmic backyard.

New Study Reveals the Body’s Metabolic Changes As You Age

June 18, 2022 by Kristen Lawrence

As we age, our bodies undergo metabolic changes, but the rate at which that happens may surprise you. Many people look back on their teenage years with fond memories of eating whatever they wanted without consequence. Back then, you could probably eat a few pounds of junk food and not gain any weight. Previously, scientists thought that a faster metabolism during the teenage years explained this minor miracle.

However, a new study reveals that your metabolism peaks much earlier than in adolescence. And, it starts to slow down later than you’d think. The findings have been published in the journal Science.

“As we age, there are a lot of physiological changes that occur in the phases of our life such as during puberty and menopause. . What’s odd is that the timing of our ‘metabolic life stages’ doesn’t appear to match the markers we associate with growing up and getting older,” said study co-author Jennifer Rood, Ph.D., Associate Executive Director for Cores and Resources at Pennington Biomedical Research Center.

An international team of scientists, including four Pennington Biomedical researchers, analyzed the average calories burned by over 6,600 people. The participants spanned 29 different countries and ranged in age from one week old to 95 years. The vast age range allowed scientists to measure metabolic changes over an entire lifespan.

The study reveals surprising age-related metabolic changes.

Most prior large-scale studies only measured basal metabolic rate (BMR) – the energy your body needs for life-sustaining functions. These vital functions include breathing, digesting food, pumping blood, circulation, and cell production. However, essential functions only account for 50-70% of the calories we burn every day. This doesn’t include the energy required for other activities like household chores, exercise, or even thinking and fidgeting.

To measure total daily energy expenditure, the team used the “doubly labeled water” method. This involves having a person drink water in which the hydrogen and oxygen have been replaced with naturally occurring “heavy” forms. It then measures how quickly the molecules get flushed out in the urine.

This method is considered the gold standard for measuring daily energy expenditure during everyday life. Scientists have utilized this technique to measure metabolism in humans since the 1980s. However, due to cost constraints, prior studies were too small to gather sufficient data. For this study, scientists obtained data from multiple labs to attempt to validate previous findings.

After gathering data and analyzing metabolism throughout a person’s life, scientists found surprising age-related metabolic changes.

Dr. Katzmarzyk said the following:

“Some people think of their teens and 20s as the age when their calorie-burning potential hits its peak. But the study shows that pound for pound, infants had the highest metabolic rates of all.”

Babies grow rapidly during their first year of life, and this requires a lot of energy. By the time they turn one, babies burn calories 50% faster for their body size than adults. And, scientists discovered that’s not just because of the explosive growth spurts babies go through.

“The babies grow rapidly, which accounts for much of the effect. However, after you control for this, their energy expenditures tend to be higher than what you would expect for their body size,” Dr. Martin said.

A growing infant’s fast metabolism may explain the effects of malnourishment during this developmental stage. Childhood hunger leads to a lower chance of survival and can affect health into adulthood.

“More research is needed to understand the metabolism of babies better. We need to know what is driving higher energy expenditures,” Dr. Martin said.

Metabolism levels out after the teenage years.

After a peak in infancy, a person’s metabolism declines by nearly 3% annually until their 20s. At this phase of life, metabolism becomes more stable. Interestingly, researchers found that the growing pains of adolescence didn’t result in increased calorie needs after taking body size into account. Even more surprisingly, they discovered that metabolism remained relatively stable from a person’s 20s through their 50s.

The team observed calorie needs during pregnancy increased, as expected. These findings imply that other factors may lead to metabolic changes in middle age. Furthermore, the data shows that metabolism doesn’t begin to decline again until after age 60. At this age, metabolism slows gradually by only 0.7% per year.

However, a person in their 90s requires 26% fewer daily calories than a middle-aged individual. This means there’s more at play than just metabolic changes. Researchers believe that lost muscle mass as we age may explain the decrease in calorie needs. Muscle burns more calories than fat, and older adults typically have a higher body fat percentage.

This still doesn’t explain all the metabolic changes that occur in older people, however.

Dr. Ravussin said:

“We took dwindling muscle mass into account. After 60, a person’s cells slow down.”

Researchers also considered varying activity levels among participants, but the patterns remained. Since both the body and brain transform aging, it’s often difficult to pinpoint what causes metabolic changes. However, this new research suggests that there’s more to it than just age-related changes in lifestyle or body composition.

“This study shows that the work cells do changes over the course of the lifespan in ways we couldn’t fully appreciate before. But massive data sets like the one we collaborated on allow us to answer questions we couldn’t address,” Dr. Ravussin said.

Final thoughts on a study revealing unexpected metabolic changes throughout a lifespan

Most people probably believe that teenagers have the fastest metabolism. It seems that they can eat whatever they want and get away with it. However, a new study reveals that babies actually have a higher energy expenditure relative to their body size. It’s still a mystery why teens feel so ravenously hungry because the research found that their calorie needs don’t increase with body size.

The study did reveal that metabolism levels out in a person’s 20s through their 50s. It then begins to decline once a person turns 60. This shouldn’t come as a surprise since this stage of life usually requires less energy. However, it’s interesting to learn that babies need more energy than teenagers for their body size.

Understanding the metabolic changes that occur over a lifespan can potentially guide nutrition and health strategies.
