Is being overweight ALWAYS unhealthy? Scientists discover the answer depends on to how efficiently the body breaks down and stores fat

A recent study proves that your weight doesn’t indicate your health. This is not — and we need to emphasize this — an excuse to overeat or snack on junk food. However, scientists are concluding that what is more important to overall health is how efficiently the body breaks down and stores fat rather than actual weight. 

Despite the paradoxical nature of the concept, in the study of obesity, it’s often the overweight people who can break down fat at a high rate. These obese individuals are considered less healthy than other who can store their body fat more effectively. When fat breaks down, a lot of the fatty acids released from the adipose tissue, or body fat, goes elsewhere in the body.

When this happens more than is necessary, the fat can accumulate to harmful levels in other tissues and organs. This excess fat will fuel insulin resistance, which is a hallmark of type-2 diabetes and heart disease. (Related: Fat Loss vs. Weight Loss: What Every Dieter Needs to Know.)

Two studies from the University of Michigan helped isolated key characteristics in fat tissue that can help obese adults store their body fat via a healthier way. Jeffrey Horowitz, principal investigator and professor of movement science at the U-M School of Kinesiology, shared that the studies also prove that aerobic exercise can contribute to healthier fat storage.

A lot of obese individuals often develop insulin resistance, and this can lead to type-2 diabetes and other chronic diseases. But Horowitz et al. determined that at least one-third of the 30 obese adults in their study didn’t develop insulin resistance.

The study looked at adipose tissue samples from the participants, which showed that the healthier group broke down fat at slower rates. The healthier participants also had fewer proteins used in fat breakdown and were more involved in fat-storing, whereas obese individuals had fewer fibrotic cells in the adipose tissue. These cells allows tissue to be more flexible, and they helped lower the activation of certain inflammatory pathways.

Horowitz explained that while the findings seem “counterintuitive,” further study can help the researchers learn more about how people can store fat more effectively. The findings can also be used to study “why some people are better at this than others.” He added that the results can be used to “design therapies and preventions that will improve some of these obesity-related metabolic conditions.”

For the second study, the researchers collected fat tissue after two groups of overweight people underwent a session of aerobic exercise. One group exercised regularly while the other group didn’t. In both groups, even a single session of exercise set off signals that caused the growth of new blood vessels in fat tissue.

The scientists also took note of indications that those who exercised regularly had more blood vessels in their fat tissue compared to the non-exercisers. This is significant since the health of most tissues are often connected to blood flow and nutrients, stated Horowitz.

As we gain weight, our fat cells expand. But if blood flow to fat tissue doesn’t increase at the same time, it might become unhealthy or, eventually, necrotic. Horowitz cautioned that the two studies are relevant because the data can be used to help obese people who are at risk for metabolic disease.

Horowitz advised that with regular exercise, people can foster a “healthier fat-storing environment” even if they occasionally overeat and gain weight. He added that both studies also championed the notion that clinicians can benefit from redefining their ingrained perception of fat.

Horowitz elaborated, “Adipose tissue is scorned because most people see it as causing disease and obesity, but in general adipose tissue doesn’t cause people to gain weight and become obese, it’s just where we store our extra energy when we do overeat… Our studies aren’t suggesting it is healthy to be obese or to overeat — but when we do overeat, it is important to have a safe place to store that extra energy.” He concluded, “When people gain the same amount of body fat, those with adaptations to their fat tissue that can more healthfully accommodate the extra fat may be protected from developing insulin resistance and obesity-related diseases. We have identified some of these adaptations.”

The holidays are approaching, preppers — don’t let up on your fitness goals

For most people the holiday season brings lots of family face time, joy and happiness, but also no shortage of bad foods that taste far too good and, thus, are generally over-consumed, leaving us feeling miserable and hefty.

As those holidays approach, however, now is not the time for preppers to lose sight of their year-round goal of remaining fit enough to fight if you have to. So in that vein, I wanted to offer you a little health and fitness reinforcement by reminding you what we’re up against.

Every year we grow older, it becomes just a little more difficult to stay in peak condition. Plus, our conditioning suffers seasonal setbacks as well when we find little motivation to hit the gym or take in a run because it’s ‘too cold’ outside.

But what’s the alternative for a prepper who’s serious about being able to endure the physical challenge a collapsing society will present? As you are aware, we can’t know when society will fall or what will actually trigger it. As such, it’s important to fight the urge during the holidays to allow colder weather and bad diets to ruin the gains we’ve made the previous year.

So here’s what you need to do in order to ensure maximum fitness throughout the holiday season and the coming year, in order to be fit to fight:

— Reward yourself for hitting the gym or the great outdoors (hikes are great in any weather — but wear your bug-out bag when you go) for an extreme fitness workout. That could be anything from allowing yourself to buy that special piece of gear you’ve been eying all year, to taking a short vacation or even giving yourself a short break from the workouts (but don’t make it more than a couple days).

— Change up your routines so that boredom doesn’t set in. Boredom, combined with unhealthy eating and colder temperatures are powerful forces that can prevent you from making the decision to hit the gym or the great outdoors. But if your workouts remain fresh and newish, they will hold your interest much more and actually motivate you to get them done.

Along those lines, I’ve just started a new workout regimen called “100s.” You pick a particular body part (bi’s and tri’s, legs, back, etc.) and do each exercise for 100 reps without stopping. Naturally, you’re going to have to use much lighter weight, but you’re going to get a max pump and really improve your endurance and muscle stamina. Granted, even with lighter weight you may not be able to do 100 reps without stopping for a few seconds, but the main thing is to try. You won’t believe your results. (Related: This Back-Blasting Extreme Workout Will Build Muscle AND Endurance.)

— Set new goals for the holidays that you’ve not set for yourself before. If you’re into some strength training, see if you can bump up your maximum bench press, for example, over the next several weeks. Or maybe see if you can quicken your sprint or sprint farther. Perhaps you can see how far you can flip a big tractor tire. Or see if you can surpass 100 reps in the “100s” challenge.

— Get a workout crew together so that you can motivate each other to go to the gym. Many times if you know you have to meet people for a workout, that is more than enough to get you off the couch, away from the turkey and dressing, and out into the cold en route to the gym.

As for the kinds of exercises you can do, I lay out several in my free e-book, “Fit to Fight: A Prepper’s Guide to Extreme Fitness for All Ages.” I’ve done every one of them many times and I have to say I’m in the best shape of my life at this point.

Like you, I’m always more tempted during the holidays to slack off my fitness goals. But as preppers who don’t know when or how stuff will hit the fan, we always have to be ready for any eventuality, especially this time of year when it’s so easy to be distracted.

Start fighting obesity tomorrow with this simple, easy step: Drink only water with your meals

Losing weight can be an arduous process, yet there’s one simple habit that can make it easier. Instead of accompanying your meals with shakes and juices, opt for plain water.

This is what helped over 1,200 elementary and middle school students in New York City shed some unwanted pounds over the course of a five-year pilot program. The placement of water dispensers in the cafeterias not only led to tripled water intake during lunchtime, but also helped the students lose small but significant amounts of weight.

“The nutrition profile doesn’t change much when people increase their plain-water intake, but we do see a significant drop in their saturated fat and sugar intake,” said University of Illinois kinesiology and community health professor Ruopeng An, who conducted a cost-benefit analysis of the program. Though the children consumed less milk, An stated that this wouldn’t pose any major nutritional hazards. (Related: Don’t Become Your Own Worst Enemy During Your Weight Loss Journey.)

“While there might potentially be some problems if children consume less whole milk, I would say those are probably minor in comparison with the costs associated with the skyrocketing rates of childhood overweight and obesity in the U.S.,” An explained.

And far from only benefiting children, drinking solely water with your meals is good for adults too. An himself performed a previous study on the effects of greater water intake among adults, and found that there was little evidence of any adverse nutritional side effects,.

Really though, it’s not at all that surprising that the students under the program lost weight. Water has been proven to aid in weight loss efforts in a number of ways, and according to Healthline.com, these are some of them:

To enjoy these amazing health benefits, make it a point follow the recommended intake of four to eight glasses, or one to two liters, of water a day. This is a general guideline, however. You may need more water than other people, or you could be one of those people who can do with a little less. Just be sure to drink water whenever you feel thirsty, as ignoring this urge can cause you to become dehydrated. Even mild dehydration can cause you to reach for food or experience a headache, neither of which are good for you. The same can’t be said of water, which is definitely something you should have everyday.

Proof junk food is like a drug: Researchers found sugary and fatty foods distract people twice as much as healthy snacks

When you’re hard at work and you get into that highly productive “zone,” it might feel like nothing can stop you. However, scientists have shown that junk food can snap you right out of focus – even if you only see it subliminally.

In the study, which was carried out by scientists at Johns Hopkins University, people were asked to work on a complex computer task that had nothing to do with food. They were instructed to find the answers as quickly as they could, classifying symbols into categories.

While they worked on the task, photos were flashed in the screen’s periphery for a mere 125 milliseconds, which is considered too fast for them to fully realize what they saw. They were shown a mix of pictures that included healthy foods; foods high in fat and calories; and non-food items like footballs, lava lamps, thumbtacks and bikes.

While all of these pictures distracted participants from the task, foods like candy, chocolate cake, hot dogs, potato chips, cheese and donuts were twice as distracting as the non-food pictures and those of healthy foods like salad, apples and carrots. Moreover, they discovered it’s not food in general that is distracting as the healthy foods were no more distracting to participants than the non-food items.

Afterward, they recreated the experiment but threw in a twist: A new group of participants ate two fun-sized candy bars before carrying out the same computer task. Interestingly, the participants who ate the candy beforehand did not find the high-calorie, high-fat food pictures to be any more distracting than those of healthy food and non-food pictures.

Now, the scientists would like to find out if eating less chocolate prior to the test or consuming other types of snacks would lead to the same effect. For example, they’d like to see how eating an apple ahead of the task would change distraction levels. They’d also like to investigate whether offering the participants money to perform the task quickly would prevent them from getting distracted to discern just how strong the pull of junk food is.

According to lead author Corbin A. Cunningham, this finding supports the old adage about not going grocery shopping when you’re hungry as the highly distracting nature of unhealthy foods could lead you to make unwise decisions. He said that even when food is irrelevant and people are trying to concentrate, junk food has a tremendous ability to sneak in and steal our attention, unless we’ve just eaten some of it!

In explaining the phenomenon, Cunningham said that one of the reasons that junk food appears more tempting than healthier options is the biological desire to eat energy-dense foods because they tend to taste better. He also believes there could be a little bit of “wanting what you can’t have” at play.

“While it is hard to tell, I think some of the rewarding nature of high calorie foods might be that we know we should only occasionally indulge in them. Thus, they become more ‘rewarding’ than foods that we could eat as much as we want,” Cunningham said. Their findings were published in the Psychonomic Bulletin and Review.

The more we can learn about what drives people to eat junk food, the better off we’ll be as a recent study published by Lancet found that a fifth of all deaths around the world are caused by junk food, processed food, and otherwise toxic or harmful food, making it just as dangerous as smoking.

Reversing Type 2 Diabetes Through Fasting

Type 2 diabetes, sometimes referred to as adult onset diabetes, doesn’t have to be permanent. You can turn your health around. Fasting and calorie restriction can help you get control of your blood sugar, lower your blood pressure, and evidence even shows that fasting can help reverse type 2 diabetes. But, before we get into how fasting can undo the damage of type 2 diabetes, we first need to understand how type 2 diabetes affects the body.

Diabetes develops when fat accumulates in areas of the body that shouldn’t accumulate fat. It all starts with an abundance of fat in your muscle tissue. Typically this is caused by a family history, poor diet, or sedentary lifestyle. This fat is called intramuscular fat. It’s like the marbling on a steak, only it’s inside your muscles, and it causes insulin resistance.[1, 2] To make matters worse, intramuscular fat causes muscles to produce toxic fat metabolites like ceramide and diacylglycerol (DAG). These toxins also cause insulin resistance. This is the characteristic that distinguishes type 1 diabetes from type 2.[3]

When blood sugar is high, the body tells the pancreas to produce insulin to lower blood sugar. However, insulin resistance causes the liver to stop responding to insulin.[4, 5] Gluconeogenesis, a process where insulin tells the liver to stop producing sugar from non-carbohydrate sources, occurs while you’re sleeping, fasting, and when you run out of blood sugar and glycogen. But when you become insulin resistant, your liver keeps producing sugar despite a high level of sugar in the blood. Consuming food that’s high in sugar is like throwing gas on the fire and the abundance of sugar is converted to fat and stored in the liver.[4]

When the liver accumulates fat, non-alcoholic fatty liver disease (NAFLD) can develop. When non-alcoholic fatty liver disease is present, the liver releases fat into the bloodstream where it’s distributed to other organs and they, just like the liver, stop responding to insulin. Especially affected is the pancreas.[5]

As fat builds up in the pancreas, its function is compromised. Since the pancreas is responsible for producing insulin, this is a major issue. Predictably, insulin production drops. Reducing body fat can help normalize blood sugar, but a lot of people begin insulin injections instead. Insulin injections help in the short-term, but also increase fat formation throughout the body, including the liver and pancreas. All the while, type 2 diabetics develop other health issues.[6] Fortunately, there is a better way.

For almost 150 years, we’ve known that fasting has serious benefits for those with diabetes. In the 1870’s, Dr. Appollinaire Bouchardet, an expert on diabetes during his time, noticed that fasting produced positive results for his diabetic patients.[7] Over 100 years ago, Dr. Elliott Joslin published research suggesting that fasting could reverse diabetes.[8] They were among the first to realize that fasting detoxes your tissues and organs of fatty deposits.

Even if someone has had type 2 diabetes for a long time, the results begin almost immediately. If you can start metabolizing the fat in your organs, you can begin to restore insulin sensitivity. And once you restore insulin sensitivity, you can get your blood sugar back on track.[7, 9]

Fasting with type 2 diabetes comes with a few potential health consequences, which is why you should only begin a fasting regimen under the watchful eye of a certified health professional who has experience and expertise with helping diabetics through this process. Ideally, have your blood tested throughout the day to monitor your blood composition and overall health. Again, if you have diabetes, do not fast without careful, attentive supervision from qualified and experienced health care professionals.

Fasting works similar to bariatric surgery, a gastric surgery that effectively reduces the size of your stomach. One study found that bariatric surgery helped 73% of participants go into diabetic remission.[10] These kind of surgeries, however, are dangerous—both the surgery itself and managing nutrition afterward. There’s the additional consequence of forever having a stomach that’s the size of a shot glass and the difficulties that come with it.[11]

Instead of going the extreme route with invasive surgery, simply adopt the post-bariatric surgery eating philosophy. After seven days of reduced calorie intake (about 500-600 calories a day), fasting glucose normalizes. After two months on this diet, your pancreas can start producing a normal level of insulin to control blood sugar.[12, 13]

In the last few years, researchers have found that reversing pancreatic damage is possible. Once you clean out the fat, the insulin-producing cells start pumping out insulin again.[6] Fasting can undo the damage to your liver and pancreas to the point that they begin to function normally again.[14]

Because it takes a few months to detox your organs of accumulated fat, intermittent fasting is the way to go. With a fasting diet, you can sustain the fast long enough to get rid of the excess fat deposits that lead to type 2 diabetes.

Monitor your blood sugar and blood pressure. Break your fast if your blood sugar exceeds 300 mg/dl or drops below 70 mg/dl.

A reduced-calorie plant-based diet may help repair the damage diabetes has wrought on your body. Remarkably, one study found that a well-planned vegan diet can lower insulin dependence by over 60% in just over two weeks—without losing any weight.[15]

Small changes lead to small improvements, moderate changes yield moderate improvements, but significant changes lead to extraordinary results. Do what’s right for your body. Follow a healthy diet to lead a healthy life. Cut out refined sugar, starches, and meat and cheese, all of which are consistently shown to promote diabetes.[16, 17, 18]

You can restore your health if you have the courage to try and the willpower to stick with it—and I am confident that you do.

Variation on the Mediterranean diet may help you make it to 100: Consider trying the “Pioppi” diet for 7 days

Renowned cardiologist Dr. Aseem Malhotra and former athlete Donal O’Neill have written a book called The Pioppi Diet: A 21-day Lifestyle Plan, which features a seven-day diet plan that adopts the regular meal plans followed by residents of Pioppi Village in Italy. Pioppi has been acknowledged by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as the home of the Mediterranean diet, and has been recognized as the world’s healthiest village. According to a Daily Mail article, residents of Pioppi are known to live past 100 years old.

Village residents are also known to include bacon and chocolates as their meal staples, but also consume a lot of beneficial oils, vegetables, oily fish and nuts. This reduces their risk of developing type-2 diabetes and heart disease. The seven-day meal plan featured in the book suggests that people start the day by taking a tablespoon of apple cider vinegar. According to the experts, this helps relieve acid reflux, prevent high blood pressure, and promote weight loss.

Likewise, the meal plan includes mostly eggs that provide an ample source of protein and helps stave off hunger pangs. The experts have also recommended undergoing intermittent fasting by restricting the eating window to between eight to nine hours only. In addition, red wine intake is not discourage as long as it is a high-quality variety. The plan also lists various food combinations that people can follow each day of the week.

The meal plan suggests that people refrain from eating solid breakfast from Mondays to Wednesdays, and recommends drinking only coffee with coconut cream in the morning. The diet plan also recommends a gradual increase of food items through out the day, which include eggs and various omelette recipes as well as fish and vegetable dishes. Likewise, the meal plan advises that people eat grilled meat, poultry, fruits and various dairy products through out the week. 

A previous study carried out by Dr. Malhotra has demonstrated that adopting a Pioppian diet may well improve the body’s overall health. According to the renowned cardiologist, following a diet low in sugar and high in beneficial fats may have greatly contributed to the residents’ remarkable longevity. In his study, the expert observed that the villagers followed a diet rich in vegetables, fish, and olive oil. Aside from this, the villagers also avoided consuming too much sugar, and rarely ate meat or dairy products. He has also found that the locals had low stress levels, drank a glass of wine daily, and slept seven hours per night. (Related: Italian village where most live to be 100 reveals the secret to a long life.)

“Yes, the locals eat pasta – but only in small quantities, and they rarely touch sugar. They only eat dessert on a Sunday, pizza once or twice a month. They take time over lunch. They don’t have a gym but they are constantly on the go…Diet is the number one issue. More than physical inactivity, smoking, and alcohol, it contributes to more disease and deaths. This should be the message from doctors – food is medicine. There is no such thing as a healthy weight, but a healthy person. That is what we should all be aiming for. Living like a Pioppian would mean a reduction in the 20 million annual deaths worldwide caused by cardiovascular disease,” said Dr. Malhotra.

Don’t get injured at night… Researchers discover cell repair driven by circadian rhythm; wounds heal 60% faster during the day

 Are you scheduled for some kind of surgery in the near future? You might want to request that it take place in the daytime. A recent study by researchers from the U.K.’s Medical Research Council (MRC) Laboratory of Molecular Biology, published in the journal Translational Medicine, has found that wounds inflicted during the day heal up to 60 percent faster than those that happen at night.

The researchers found that not only are the skin cells that repair cuts and burns more efficient in the daytime, but more collagen is also deposited at the wound site immediately after and for the following two weeks after a daytime wound takes place – ensuring a more efficient healing process.

The researchers’ findings were based on laboratory tests using skin cells called fibroblasts and keratinocytes, as well as from studies with mice.

The Daily Mail, reporting on the study, noted:

[D]uring the internal body clock’s ‘daytime’, wounds to the skin healed almost twice as efficiently as wounds incurred during the night. …

The researchers said faster healing took place because skin cells carried out faster repairs at the site of the wound to repair it much faster during the body clock’s daytime.

The difference between daytime and nighttime healing is one of the many facets of the human body controlled by the circadian rhythm – also known as the body clock. The body clock controls everything from sleeping to hormone secretion, and even how quickly you metabolize food.

Dr. John O’Neill, the study’s senior author explained, “This is the first time that the circadian clock within individual skin cells has been shown to determine how effectively they respond to injuries. We consistently see about a two-fold difference in wound healing speed between the body clock’s day and night. It may be that our bodies have evolved to heal fastest during the day when injuries are more likely to occur.”

Amazingly, this process was not governed by signals between cells, but by circadian clocks within the cells themselves, since the results were derived from human and mouse skin cells grown in laboratory dishes.

The cell repair was mainly driven by a protein called actin, filaments of which provide movement and structure, acting like muscles within the cell.

This study has huge implications for the future of surgery.

O’Neill noted, “In both cells and mice, we can reset the tissue healing response by tricking the cells into thinking it’s a different time of day – such as by turning the lights on at night and off at different times of day for the mice, or using body clock-altering drugs on cells in the lab.” He added, “It may be that healing time could be improved by resetting the cells’ clocks prior to surgery, perhaps by applying drugs that can reset the biological clock to the time of best healing in the operation site.”

This improved daytime healing is true of burns, too. As part of their study, the researchers examined the healing patterns of 118 burn patients registered in a major burn unit database in England and Wales. They found that burn victims who were burnt at night – between 8 p.m. and 8 a.m. – took about 60 percent longer to heal than people who sustained their burns during the day – between 8 a.m. and 8 p.m.

In fact, those who received their burns in the day were 95 percent healed within just 17 days, while those who were burnt at night took about 28 days to achieve the same level of healing. (Related: New “smart” bandages will dramatically cut healing time for wounds in chronic patients.)

The researchers are eager to engage in further research to determine whether changing surgery times or using drugs to reset patients’ circadian rhythms prior to surgery might result in better and faster healing. (Related: Discover all the latest medical breakthroughs at Medicine.news.)

A high-fat diet encourages the growth of fungi in the gut, which makes for an unhealthy microbiota and contributes to obesity, study finds

A study finds that eating a diet high in fat not only gives you extra calories, but also changes the growth of fungi in the gut, which makes for an unhealthy microbiota and contributes to weight gain or obesity, as reported by the Science Daily.

Researchers from the University of Minnesota conducted the study by using two groups of mice. One group was fed with a diet high in fat, while the other was fed with a normal diet. They found that the group of mice fed with a high-fat diet had a higher number of 19 bacterial and six fungal taxa, compared to the micriobiome found in the group of mice with a normal diet. Moreover, they discovered that the rats fed with a high-fat diet had slower metabolic function, in which they gained weight and showed other symptoms of obesity such as insulin resistance, than those rats with a normal dietary plan.

Cheryl Gale, lead author of the study and associate professor in the Department of Pediatrics at the University of Minnesota, explained that the relationship of fungi and changes in diet are changing as well as the relationship between fungi and bacteria.

“These kingdoms are not in isolation. If one changes, it is going to impact the community structure and maybe the functional structure of other kingdoms as well. I think that is where the microbiome field is moving,” she said.

Over the years of analyzing the relationship of gut microbiomes and health, past studies have found that microbes in the gut change the way we store fat, how we balance glucose levels in the blood, and how we respond to hormones that change our appetites. On the other hand, the wrong mix of microbes in the gut seem to play important roles in the development of obesity and diabetes. (Related: How gut bacteria can make you fat, or help you lose weight.)

“We really need to be looking at all the microbes and how they are interacting with each other to get a full picture of what the microbiome structure and function is in a given individual,” said Gale.

The study was published in mSphere, a journal of the American Society for Microbiology.

You are obese or overweight if there is an energy imbalance between the calories you consume and the calories you spend. Unhealthy diet, sedentary lifestyle, and genetics are the main causes of obesity. Overweight adults have a body mass index (BMI) greater than or equal to 25, while obese adults have a BMI greater than or equal to 30, according to the World Health Organization (WHO).

According to the WHO, more than 1.9 billion adults were overweight, while 650 million of them were obese in 2016 worldwide. Meanwhile in the United States, the prevalence of obesity among adults was 36.5 percent in 2011 to 2014, according to the records of the Centers for Disease Control and Prevention.

Obesity increases the risk of developing cardiovascular diseases, such as heart disease and stroke — which were the leading cause of death in 2012. It also increases the chances of having diabetes, musculoskeletal disorders, such as osteoarthritis, and some cancers including endometrial, breast, ovarian, prostate, liver, gallbladder, kidney, and colon.

Limb regeneration: Scientists have discovered that the human brain can remap nerves and motor pathways to artificial limbs

For the more than 1.7 million people living with the loss of a limb in the United States, a great beacon of hope is targeted motor and sensory reinnervation (TMSR). This surgical procedure allows patients who receive prosthetic limbs to exercise much greater control over their new motorized limbs and even to “feel” touch in the area of the missing limb.

Science Daily explains it as follows:

Targeted muscle and sensory reinnervation (TMSR) is used to improve the control of upper limb prostheses. Residual nerves from the amputated limb are transferred to reinnervate and activate new muscle targets. This way, a patient fitted with a TMSR prosthetic “sends” motor commands to the re-innervated muscles, where his or her movement intentions are decoded and sent to the prosthetic limb. On the other hand, direct stimulation of the skin over the re-innervated muscles is sent back to the brain, inducing touch perception on the missing limb.

To better understand exactly how the brain sends these messages and “feels” touch in this way, scientists from the Swiss Federal Institute of Technology (EPFL) used functional MRI to examine how the brain re-routes motor and sensory pathways. The researchers hope that an understanding of how the brain does this will enable scientists to fine-tune such control. Their study was published in the journal Brain.

Three Swiss patients who had lost an upper limb, had undergone TMSR, and who were proficient in the use of their prosthetic limbs, were included in the study. (Related. Did you know that most amputations are the result of diabetes? Discover how you can prevent diabetes with everyday foods.)

Using ultra-high field 7T functional magnetic resonance imaging (fMRI), the research team was able to measure the patients’ brain activities by measuring blood flow. This provided them with an excellent understanding of the “cortical organization of primary motor and somatosensory cortex of each patient.”

When comparing the cortex maps of the study patients to those of individuals who had not undergone amputations, the researchers were surprised to discover that there was very little difference when it came to topography, extent and strength. On the other hand, there were great differences when scans from patients with amputated limbs who had not received TMSR were compared to patients who had never lost a limb. This indicates clearly that TMSR has profound effects on the brain’s motor map. (Related: Discover more medical breakthroughs at Medicine.news.)

Science Daily explains the results in more detail:

The somatosensory maps showed that the brain had preserved its original topographical organization, although to a lesser degree than in healthy subjects. Moreover, when investigating the connections between upper-limb maps in both cortices, the researchers found normal connections in the TMSR patients, which were comparable with healthy controls. However, preservation of original mapping was again reduced in non-TMSR patients, showing that the TMSR procedure preserves strong functional connections between primary sensory and motor cortex.

Though the researchers are cautiously optimistic, they do note that TMSR still needs work.

For one thing, certain connections were still just as weak in the TMSR patients as they were in the non-TMSR patients. Unfortunately, this means that after TMSR surgery, limbs still do not move and feel exactly like “real” limbs, nor are they encoded by the patient’s brain in the exact same way as a real limb would be.

Nonetheless, the study has helped researchers to recognize that the results of TMSR would likely be greatly improved by the implementation of systematic somatosensory feedback linked to the movements of the bionic limbs.

A future where the loss of a limb is no longer a devastating diagnosis may be just around the corner.
