Everything You Know About Avoidance Is Wrong

… Or is it? That is the eternal question. Despite decades of scientific research, there are still as many theories about food as there are theorists.

Rob Lawson, who teaches basic nutrition for athletes, disagrees. In an interview podcast with The Bulletproof Executive he presented a viewpoint based on the premise that being “ridiculously obsessive” about nutrition is harmful, and that “You have to eat the foods that you like.” Lawson said,

You can work any food you like into your program as long as you’re smart about it… I think it helps in the long term when people realize they can eat anything they want as long as they are accountable for the amount and they make sure they are getting protein, essential fatty acids, vegetables, and fruits in. As long as you hit certain base levels, anything on top of that as long as you can work it into your calorie budget.

He holds that there are many different paths, but no one absolute way that is guaranteed to work for everyone, and “as long as you can make it work for you that’s really all that matters in the end.” Also, in its introduction, this transcript contains a generic Warning and Disclaimer that says, “We certify that at least one statement on the above-mentioned web sites and/or in this report is wrong” — without specifying which statement it is.

Downright sacrilege

Of course, there is always a fire-breathing heretic, in this case exemplified by David B. Allison, Ph.D., who expressed the view that people who try to eat the “right” foods — like veggies, fruit, whole grains, and fat-free dairy products — are often confused about the healthiness of food in relation to its calorie content. He once wrote,

People have, of course, lost weight on diets rich in foods generally thought of as healthy, but they’ve also lost weight on both high-fat and low-fat diets, and even on diets consisting only of food purchased at McDonald’s or composed largely of Twinkies.

Do these ideas have traction? Maybe what is true for an obese child, struggling with many different issues (including too much sedentary, passive activity) is not true for an adult athlete who works out every day with an abundance of actual, calorie-burning activity. And/or maybe a grownup with concrete goals and a sterling performance ethic can have a bag of chips once in a while, without triggering the whole edifice of self-care to come tumbling down. Is it worth taking the risk?

Oh, but…

As we know, in Dr. Pretlow’s W8Loss2Go program, a key element is recognizing that certain problem foods just have to be avoided. And this isn’t a mere theory; it has been shown. In the same way that a recovering alcoholic simply can’t drink, there are other people who simply cannot open a bag of potato chips without risking the loss of all the hard work spent keeping their weight within bounds.

This is why the techniques recommended in “Addiction Model Intervention for Obesity in Young People,” by Dr. Pretlow and Carol M. Stock, JD, MSN, are so important. The troubled person identifies and lists all problem foods.

Seventy percent (70%) of these participants seemed truly dependent/addicted to the foods, in that they reported cravings for the food, sought out or purchased the food, and had significant difficulty staying away from it.

Then, the person figures out all the circumstances and occurrences that can trigger a harmful eating episode, and eliminates them. For instance, if watching a suspenseful movie brings on the urge to snack, it might be necessary to switch to an alternate form of entertainment, or maybe even get up and move around. And guess what? To avoid the triggers is much less wear and tear on the nervous system than letting matters progress to the stage where you have to face up to actual food.

Coronavirus Chronicles — More About the Other Perfect Storm

When two sets of circumstances come together in a way that is synergistic, and add up to more than the sum of their parts, we have a problem. Another thing to bear in mind is that, in many contexts, there is not much point in distinguishing between obesity age groups. Overweight and obese adults are former overweight and obese children. Likewise, overweight and obese children will quite probably become overweight and obese adults. There are more similarities than differences.

It has become apparent that the virus does not discriminate in the matter of age. It will take anybody. But here, a contradiction arises. In another way, the virus does very much discriminate. It shows a preference for victims belonging to certain races and ethnicities.

The previous post mentioned the COVID Collaborative’s report on children who have lost their adult caregivers to the virus. In this country, it’s around 170,000 children so far. The report drops this shocker about our nation’s capital:

The District of Columbia had the widest disparities in caregiver loss, where Black and Hispanic children’s rates of caregiver loss were 11 and 18 times the rates of loss for White children, respectively.

No one who pays attention was surprised to learn that, throughout the U.S., Black and Hispanic children are affected by caregiver loss about two and a half times as much as white kids. Asian children are also worse off. The most severely affected children are American Indian, Alaska Native, Native Hawaiian, and Pacific Islander.

Orphaned and semi-orphaned

The point is almost impossible to overstate: Obesity and COVID-19 have a relationship that goes far beyond compatibility, into totally overboard Public Displays of Affection. They are beyond shame, a match made in Hades. The virus frequently — and we have no idea yet exactly how often — sets up obese kids for a future of distress in which eating disorders will be the least of their problems. The group says,

Children and adolescents depend on their caregivers for financial, emotional, and developmental support, and the death of a parent or caregiver can hinder a child’s development and success for the rest of their lives. The impacts of losing one or both parents can include anxiety, depression, PTSD, substance abuse, suicide, poor academic outcomes, increased rates of high school dropout, economic turmoil, and general instability.

What a perfect recipe for an ever-increasingly obese population! This is why COVID Collaborative envisions a number of clinical, economic, and social interventions that could help. They include the creation of a COVID-19 Bereaved Children’s Fund, and the expansion of services for children who have lost their significant adults to the pandemic, including mentoring, peer support groups, and other “evidence-based policies, programs, and practices to address grief and trauma.” They also call for additions to current social service and mental health care systems, and “executive action from the federal government to support these children now.”

Coronavirus Chronicles — The Other Perfect Storm

The concept of the “perfect storm” is not a new one at Childhood Obesity News, and now there is a different kind of perfect storm, one that provides a splendid environment for childhood obesity to increase. What has COVID-19 brought in its wake?

With people staying in more, there may be too much opportunity to engage in recreational eating, or comfort eating. On the other hand, depending on circumstances, a family might be experiencing heightened food insecurity. Even if healthful food is available, parents or other caregivers might be too stressed to prepare or supervise meals effectively.

Kids get too much sleep; or disrupted sleep. They spend too much time sitting on their posteriors, interacting with screens. There is a lack of opportunity to burn off calories in healthy ways. Routine doctor visits have probably been suspended, and children with actionable complaints are likely to have too much else wrong to focus on body fat at the moment.

This has been a partial list, and no doubt each family can add unique obstacles it has faced — each one of which contributes in some way to the danger of increasing obesity.

Hidden pain

The COVID Collaborative issued a report meant to stimulate the government, along with partners from the non-profit and private sectors of society, to appropriately support children who have lost significant adults to the pandemic. They have gathered information through schools, community-based organizations, faith-based institutions, primary care settings, and public records. The document, titled “Hidden Pain,” became available last month.

The United States has lost 760,000 of its citizens to COVID-19, although even that number is contested by those who believe that certain types of deaths should have also been counted as part of the toll. Among the casualties are “parents, custodial grandparents, or other caregivers on whom children had relied for financial, emotional, and developmental support.”

The point is also made that many of these bereaved children were not living in the lap of luxury, to begin with, but were already struggling with various limitations and deprivations when they lost their responsible adults — these deaths being described as…

[…] devastating losses can impact their development and success for the rest of their lives.

The authors go on to say,

The magnitude of the total loss of life from COVID-19 outpaces deaths in every U.S. war, and the impact of that loss on children in less than two years is profound.

To phrase that another way, out of every 450 children in the USA, one has lost a parent or in-home caregiver to the virus. At least 167,000 vulnerable children have lost caregivers, and 70% of those kids were younger than 13 when it happened. That number includes more than 34,000 kids age four and younger. A total of 72,000 children lost a parent, and 67,000 lost a grandparent who was a caregiver in their home. More than 13,000 lost their only in-home caregiver.

As if all that death were not traumatic enough, a side effect has been children losing their eligibility for “publicly funded programming like Head Start and Early Head Start” that require co-payments and parent volunteer participation.

That topic will continue in the next post. Meanwhile, let’s end this one with a mind-blowing statistic: Half of the entire caregiver loss originated in just five American states: California, Florida, Georgia, New York, and Texas.

Coronavirus Chronicles — The Sicker Quicker Phase

For a long time, COVID-19 was believed to exclusively haunt older people, especially if they were overweight. Last summer, around 97% of all COVID-hospitalized patients were unvaxxed, and large segments of society were acting as if the danger had passed and everything should be wide open. Then, “youngification” began to set in.

In early August of 2021, the death of a 28-year-old was noteworthy. The ICU admission of an 18-year-old was news. A 33-year-old bodybuilder was astonished to learn that he was infected. The spotlight turned on the diagnosed young, especially if they were unvaccinated. In all fairness, older and more vulnerable people had been prioritized for shots. It was not until months later that personal responsibility became such a factor.

As “younger, sicker, quicker” became a slogan among medical personnel, the Delta variant was blamed. Some professionals were saying it felt like an entirely different disease. Health care institutions, colleges, and some other places started to get serious about requiring that participants be immunized. Now, with the notorious Omicron strain active, those days seem quaintly old-fashioned.

Summer of disbelief

In early August, yet another super-fit man in his early 40s posthumously made the news. Indeed, this was becoming a common occurrence. John Eyers, described as “an Ironman and keen mountain climber,” refused vaccination and died after being ill with COVID for a month. The wrinkle is, his twin sister, who was vaccinated, remained healthy and lived to mourn him. She told the press, “The only pre-existing health condition he had was the belief in his own immortality. He thought if he contracted COVID he would be OK.” Before being placed on a ventilator, Eyers did say that he wished he had taken the shots.

Another patient put into a medically induced coma and hooked up to a ventilator was the Denver Broncos’ formerly healthy, active coach for fitness and nutrition, Bill Phillips. He had not expected to catch the virus twice. A few months earlier, at 56, he went through a bout of COVID, and assumed that he would be immune, and not need vaccination. Phillips told reporter James Crump that the mistake had nearly cost his life:

When you come this close to death, your entire being deteriorates on every level… you don’t just wake up and go on living your life. I have to rebuild my body, mind, and entire life from the ground up.

This act of standing for a couple seconds, with a lot of support, was definitely harder than a 600 lbs squat and more painful than I can ever describe.

The point is, healthy people catch the disease. Young people catch it. It is caught by people who are both young and healthy. Nobody can afford to take anything for granted. The financial aspect alone is horrifying. If we thought student loan debt was onerous, wait till we see the bills for youthful coronavirus.

Coronavirus Chronicles — COVID-19 and Kids, More to the Story

We were discussing how medical professionals turn to social media to report their own observations and consult their colleagues about current developments.

Emily Porter, M.D. (@dremilyportermd) tweeted that her five-year-old caught the virus at school in December and transmitted it to the entire family of six. Gastroenterologist Tom Wallach (@md_wallach) noted via Twitter that “90% of my consults this last week on service were for complications of pediatric COVID. ” Conversations with pediatricians all over the country convinced him that his experience was widely shared, and “there’s some interesting and complicated pathology going on here.” He also mentions, not surprisingly, that most of the children he has seen, in or out of a hospital, had not been vaccinated.

In the same thread, a grandmother/retired doctor wrote, “Omicron doesn’t seem at all “mild” for the pediatric crowd.” A civilian wrote that every baby she knows right now has COVID, and she knows “a ton of babies.” Even if not literally true, this speaks for the weight of sorrow and frustration that has come with the realization that yes, children can catch the virus — even infants.

Last week, Tom Perumean wrote for MSN.com that the “insidious” virus is causing serious damage, especially among children who are obese. He quotes Dr. Kyle Happel:

We do have pretty good evidence that COVID-19 virus itself can indeed infect fat cells. So individuals that have more adipose, or more fat tissue, are more likely to have a higher load of the virus in their body… And so, to sum it up, people who are obese are much more likely to experience severe inflammation, organ failure or blood clots.

He went on to speak about the extensive inflammatory response that COVID-19 usually elicits, which looks to be more harmful than the virus itself. The writer also quoted pediatrician Dr. Anthony Hudson:

There is a phenomenon associated with childhood obesity and the rates at which the lungs in the larger airways grow that essentially leads to air trapping in the lungs and again worsening prognosis of COVID-19 infection.

When authorities are deciding which children need to be hospitalized, obesity is a determinant, according to the Centers for Disease Control and Prevention.

An obese child is starting out with a disadvantage, because chances are they already have poor cardiovascular health and/or pre-existing lung dysfunction. Pamela Comme wrote about a report that covered children and teens with COVID-19 in six different hospitals, during July and August of 2021:

Of those who were admitted, 77.9% were hospitalized for acute COVID-19. Approximately two-thirds of those aged 12-17 years had obesity.

If a child has already shown diabetes symptoms, those will probably get worse too. Kids under 18 with COVID have a higher likelihood of receiving a new diabetes diagnosis than those who have not caught the virus.

Coronavirus Chronicles — COVID-19 and Kids, the Volume Increases

It is all well and good to talk about trusting science, but first, we have to be aware of it. Even the pre-print online press is unable to keep pace with the enormous number of studies, and theoretical speculations, concerning the virus. Two trends seem to be emerging. One is that the virus may be responsible for a lot more illnesses than was previously suspected.

As an example, Dr. Farid Jalali strongly recommends accepting the evidence that “acute COVID19 is — at its core — a severe autoimmune platelet activating disorder.” This is important because then, many of the hospitalizations that are categorized as “with COVID” — like heart attacks, strokes, lung clots, and other malfunctions — become clearly seen as actually “for” COVID. In other words, it seems like many conditions that have been considered as co-morbidities are not separate entities at all, but integral parts of COVID-19.

Another medical professional points out how people are being called “asymptomatic” just because they have no cough or fever, when actually they have quite a few different symptoms which should be recognized. Someone else notes that a lot of patients have been sent home with no early intervention, only to return to the ER with life-threatening problems.

A big bump

Another change is, all of a sudden, there is a lot more talk about the combined topic of children plus COVID-19. Pediatric COVID is a new, small field, and nurses and doctors share their firsthand experiences by way of social media. They want to speak now about what might save a life tomorrow, and that is understandable.

The basis of every medical advance is anecdotal evidence. A knowledgeable person notices an anomaly; gets curious; asks around to see if anybody else has clocked the discrepancy. For example, what if a breastfeeding mother is vaccinated against COVID, and almost immediately, both she and the baby have breathing problems? People wonder how to think about that. Is it an isolated incident, whose cause is not yet understood? Or is it a trend, a warning that should immediately be addressed with legislation?

You can’t Google it, because the information just isn’t out there yet. Maybe not enough lactating moms have been vaccinated, to make a statistical difference. And even if a question is deemed important, every research project needs resources, funding, willing and qualified participants, and so forth. Given all that, it still might be a year or longer before anything is published that addresses your question.

Crowdsourcing

So why not ask your college roommate, who now runs a department at a major clinic, if she has seen this particular problem? Does she know of any person in academia who hopes to find or assemble a group of recently vaccinated nursing mothers? In fact, why not expand the inquiry and ask around on Twitter? Plenty of doctors, nurses, therapists, and technicians readily share their observations, reservations, and perturbations.

Some people get sarcastic. Some point out that schools have been known as super-spreader locations since forever; as places rife with contagion, where something is always “going around.” And yet, the most obvious and sensible precautions against COVID have not been taken.

Cory Doctorow, who has an illustrious reputation in several fields, has been writing about a difference of opinion with his child’s school:

They’ve upgraded their filters, but refuse to open the windows. Every one of my kid’s classes has one or more kids who won’t mask. Every day, we get notifications of double-digit new cases.

Filters are great! But they only work if the maskless plague-carrier next to my kid exhales his infectious exhaust-plume into the filter before it reaches my kid. Open windows create high-turbulence airflows that would improve her chances even if she’s downwind of a maskless kid.

Coronavirus Chronicles — Body Weight and Body Fat

Obesity and the coronavirus make things easier for each other, and harder for the rest of us. The two harmful conditions could not keep their relationship discreet forever. More and more experts are noticing how relentlessly they work together. It is very clear, they are friends with benefits only for each other, and pain for everybody else.

Forty percent of Americans are said to be obese. Obese people are more apt to catch COVID-19, more likely to get very sick, and more likely to die from it. In countries where most of the adults are overweight, the death rate is 10 times higher than in slimmer countries. The adults who face these odds are yesterday’s obese children. Today’s obese children are tomorrow’s obese adults.

Speaking of which, we are told by the American Medical Association that “Overweight or obesity increased among 5- through 11-year-olds from 36.2% to 45.7% during the pandemic.” One school of thought holds that the government has been wrong to close parks, gyms, schools, and other locations where people should be able to exercise and burn calories to avoid obesity. There seems to be some room for nuance. Why not keep a park open, if people stay far away from each other? On the other hand, a gym could so easily be the perfect environment for spreading COVID.

Reprieve?

Still, there is hope. According to Steven Nissen, M.D., senior author of a paper explaining recent Cleveland Clinic research,

Striking findings from the current study support the reversibility of the health consequences of obesity in the patients with COVID-19. This study suggests that an emphasis on weight loss as a public health strategy can improve outcomes during the COVID-19 pandemic and future outbreaks or related infectious diseases.

Specifically, a group of obese patients who had already lost weight through bariatric surgery had a 60% lower risk of developing severe COVID-19 complications. So yes, excessive body weight is a modifiable risk factor. But surgery is expensive, with a long and arduous qualifying process. Most people with the ability to lose weight through bariatric surgery have probably already tried it, or at least looked into it. When it comes to 40% of the population, surgical intervention is not a likely solution.

What else is there? One Boston obesity clinic’s waiting list has more than 1,000 names on it, most of them added since the pandemic began. A lot of people have, in the words of Dr. Fatima Cody Stanford, “really made that connection between obesity and COVID and the need for them to get appropriate care.” Where and how do they procure such care? Those are difficult questions.

News about news

Recently a news network tweeted something about the proven link between obesity and COVID-19, and fellow media experts took the opportunity to get all snarky, pointing out that the “new” studies they cited had actually been around for a while. (August 2020, February 2021, and April 2021). This is the kind of nonsense that adult professionals engage in while millions suffer and die.

Meet Your Fat, Continued

We have seen that fat can make more fat. It can manufacture other substances too:

In addition to adipocytes, adipose tissue contains numerous other cells that are able to produce certain hormones… Through the actions of these hormones, adipose tissue plays an important role in the regulation of glucose, cholesterol and the metabolism of sex hormones.

See the source article for the names of all those chemicals. They are involved in intercellular communication, blood clotting, blood pressure, insulin sensitivity, energy storage and energy release, and other important matters. A lot of complicated interactions take place. Here is one insight from a year’s worth of lab research, described by Sylvia Tara, Ph.D., in The Secret Life of Fat,

Linoleic acid is a fatty acid […] a signaling molecule that suppresses inflammation in the body. When linoleic acid was missing, the rats developed symptoms of inflammatory disease.

The adipose tissue components of fat live in various places. The internal organs, or viscera, are encased in (surprise!) visceral fat. Men tend to get this kind more, and such belly fat is said to make them apple-shaped.

In the medical language of Latin, subcutaneous fat dwells under the skin, and is the type that tends to afflict women more, especially below the waist, making them pear-shaped. Body fat can also be found in bone marrow, in breast tissue, and amongst muscles.

Brown fat, dense with mitochondria, is something that babies have a lot of, to keep them warm. Adults keep traces of it, and brown fat is the subject of ongoing scientific investigation.

What are the rules?

According to an article from Harvard University, fat distribution is “influenced by several factors, including heredity and hormones.” Women get slammed for having generous hips and thighs, which are nowhere near as life-threatening as the aggressive, typically male bellies.

For a while now, visceral fat has been recognized as more hazardous than the subcutaneous kind. It just sits around, needlessly cushioning organs that would get along fine without padding between them. Visceral fat is implicated in not only metabolic problems, but hypertension, cardiovascular disease, breast cancer, fatty gallbladder, and erectile dysfunction.

What does get hard is the “beer belly,” a misnomer because anyone can grow one. It’s not just a drinking thing, or even a male thing. Women get it too, especially as they age. The firmness of the extended midsection signals extra risk.

Too many of any kind of calories, whether they’re from alcohol or sugary foods or just from eating too much food, can increase belly fat… Beer can also interfere with fat burn, because your liver will preferentially burn alcohol instead of fat when it is consumed.

The Cleveland Clinic says the fat…

[…] is packed in tightly and, as it builds up, it will push the abdominal wall outward, exaggerating the appearance of the beer belly. The abdominal wall itself is made of muscle and tough fibrous tissues and is very firm; thus the belly will feel hard.

But just because it’s firm and maybe even muscular, does not mean it’s good.

Meet Your Fat

Adipose tissue or fat is made of cells, and each adipocyte contains fat molecules which it can keep in storage or send out for conversion into energy. In her book, The Secret Life of Fat, Sylvia Tara, Ph.D., noted that fat cells are very accommodating, and can “expand their volume more than one thousand times normal size by pushing other cell contents off to the side.”

Imagine a balloon that could expand so much. What kind of magical stuff must it be made of?

Besides making you hate your jeans, fat can do a lot of things. Fat controls appetite and holds some sway over human emotions… and rationality itself. Tara wrote,

Brain cells are particularly dependent on fat. Parts of them are sheathed in a substance called myelin, which insulates them and ensures signals are not lost, similar to the way rubber insulates wires. Guess what myelin is made of — fat! Myelin is 80 percent lipids, which means fat is actually required to think.

Fat can reach out and invade other organs, as in Fatty Liver Disease, one of the dangers faced by obese children. It insulates organs and produces heat. It heeds signals from all over the body, and responds by cranking out hormones. These in turn affect such attention-getting conditions as obesity, eating disorders, and diabetes.

Fat is absolutely necessary, and people with a rare condition of having insufficient fat are very sick indeed, if not deceased. When the weight-conscious dieter tries to reduce fat, the body pushes back. It doesn’t realize you are trying to do this for ultimately healthful reasons. It thinks you are trying to kill it. Expanding on this topic, Tara wrote,

The membrane around each body cell is made of fat and cholesterol — the two archnemeses of the modern diet. The membrane acts as a wall around the cell to confine the contents as well as give it structure. It is also a protective shield, allowing nutrients, hormones, and metabolic by-products in and out. In other words, every single cell in our bodies only exists thanks to the lipid-and-cholesterol membrane that surrounds it.

And then along comes the presumptuous human, trying to deny the cell walls the fat and cholesterol they need!

Fat is an organ

Fat is an organ, specifically an endocrine organ, and according to its proponents, the body’s largest organ (not the skin; nor the liver). Like other organs, fat contains nerve cells and blood vessels. Furthermore, it can reproduce itself. It used to be thought that body fat was just a container, “passive storage with no metabolic capabilities.” But as it turns out, adipocytes can make more fat.

Tara compares the whole process to banking practices:

Glucose, a form of sugar, is like cash because it instantly supplies the body’s current energy needs… When we have too much cash hanging around, we deposit some into a checking account. In the body, glycogen is that standby reserve — the liver and muscles create glycogen out of glucose…

Fat is altogether different. Unlike glycogen, fat is not simply glucose stacked away and available… Fat is the certificate of deposit: not easy to get to, but it can safely hold a lot of energy in reserve.

Coronavirus Chronicles — The Many Faces of Fat

Yesterday’s post ended with a quotation from Dr. David Kass, who succinctly states that if a person is very obese, fat is their body’s single biggest organ. Wait, it’s what? An organ? Do we mean that fat is not just an inert mass of goop? Exactly. Fat has agency; it does things. Fat might even be said to have an agenda — one in direct opposition to the plans of the brain and other body parts. For instance, fat apparently is willing to provide a haven where coronavirus can safely conceal itself. But what has it been doing previously, all these years?

That answer depends on what kind of fat is being discussed, and the condition of the body it resides in. A Healthline article breaks down the particulars. White fat stores energy, and also tells estrogen, leptin, insulin, cortisol, and growth hormone how to perform. Some of it is absolutely necessary, but too much of it can do a lot of damage in the ways we hear so many warnings about — type 2 diabetes, hypertension, disease of coronary arteries, kidneys, liver, and more.

Brown fat is found mainly in babies, and burns fatty acids to keep them warm. If weight-control scientists could find a way to increase this in adults, they would be happy. Beige (or brite) fat seems to also have that beneficial effect. Essential fat is found in places like the brain and the membranes that protect organs, and women need more of it than men do. It…

[…] plays a major role in hormone regulation, including the hormones that control fertility, vitamin absorption, and temperature regulation.

Subcutaneous fat, the kind that mainly shows, is under the skin. A properly trained person, taking caliper measurements in certain locations, can form a pretty accurate assessment of a body’s total fat percentage.

Visceral (or belly) fat is the worst, and the hardest to get rid of. Entombing its heart, liver, and other internal organs in globs of visceral fat is a terrible thing to do to the body, just an open invitation to every co-morbidity out there. Visceral fat is the body saying “I want to die, come and get me.” If its previous reputation is any indication, visceral fat would be delighted to offer sanctuary to random virus organisms. For Gizmodo, Ed Cara wrote:

[E]vidence from the lab and in patients has suggested that the virus can travel throughout the body and infect other tissues, too, thanks to the receptors it uses to hijack cells. Recently, for instance, scientists found evidence that the coronavirus can readily infect fat and immune cells.

National Institutes of Health researchers “performed complete autopsies on 44 people who had been infected with the coronavirus.” In 39 of those cases, the virus was why they died. In all but five cases, the infection was directly implicated in the person’s death. Evidence of the virus was found throughout the bodies of all the subjects — even if the person had mild symptoms or none. It was found “in the muscle, skin, adipose (fat), and peripheral nervous tissue of 68% of patients.”

The problem that many researchers are concerned with is, how are people still suffering from a disease that gives every sign of being over? “Some experts believe that at least some cases of long covid can be attributed to persistent infection.” Is the body itself still reacting against the memory of a foreign invader? Or is the invader still on the scene, hiding perhaps in fat cells?
