A carnivore diet is a restrictive diet that only includes meat, fish, and other animal products like dairy and eggs. More recently, it has been brought into the limelight by influencers and social media personalities. In fact, there is a whole community of "meatfluencer" who are sharing their meat-eating plans. One of them is Dr Paul Saladino MD, whose belief that there was no better way to prevent chronic diseases than a carnivore diet prompted him to write books and post videos regarding the same. He believed so much in this eating plan that he became a go-to person for many following the same plan, until recently, when he decided to quit.

Here Are Seven Reasons Why He Decided To Quit

Carnivore Diet Disrupted His Sleep

Switching to an all-meat diet isn't always straightforward, especially when it comes to digestion—a lesson Dr Saladino learned firsthand. He experienced sleep disturbances, likely due to the difficulty of digesting high-protein meals. Since protein takes longer to break down, it demands more energy from the body, which can interfere with rest.

According to Johns Hopkins Medicine, digestion slows by up to 50% during sleep. Additionally, many types of meat contain tyramine, a compound derived from the amino acid tyrosine. Increased tyramine intake can lead to health issues and also triggers the release of norepinephrine, a hormone that raises heart rate and blood pressure, making restful sleep harder to achieve.

He also experienced hypnagogic jerks—sudden muscle spasms that jolt the body awake. "I would fall asleep but then jerk myself awake like I was falling multiple times. It was stressful and traumatic, leading to poor sleep," he shared in his YouTube video.

Eating Only Meat May Have Triggered Heart Palpitations

Another concerning side effect Dr Saladino experienced was heart palpitations—episodes where his heart felt like it was racing or fluttering. While stress is a common cause, few would immediately link palpitations to meat consumption.

However, a sudden shift to an all-meat diet can lead to electrolyte imbalances. The elimination of carbohydrates lowers insulin levels, prompting the kidneys to excrete more sodium. This disrupts the balance of essential minerals like potassium and magnesium, which are crucial for heart function.

Muscle Cramps Became Persistent

Dr Saladino also suffered from frequent muscle cramps while following the carnivore diet. In a post on X, he emphasized the importance of maintaining adequate magnesium, calcium, and potassium levels to prevent cramping. He initially believed that animal-based foods provided sufficient minerals, but his ongoing cramps led him to reconsider.

"I started to think maybe long-term ketosis is not great for me,” he admitted on the *More Plates More Dates* podcast. “Probably not a great thing for most humans."

His Testosterone Levels Dropped Significantly

Dr Saladino also saw a decline in his testosterone levels after following the carnivore diet for over a year. "At the beginning of my carnivore experiment, my testosterone was about 800. After a year to a year and a half, it had dropped to around 500," he revealed.

The issue likely stems from excessive protein intake, which can elevate inflammation and disrupt hormone levels. A 2022 study published in Nutrition and Health found that consuming more than 35% of daily calories from protein can lead to various negative effects, including reduced testosterone.

He Had Chronically Low Insulin Levels

Because he largely eliminated carbohydrates—except for a small amount of fruit—Dr Saladino developed persistently low blood sugar. In his YouTube video, he explained, "I had very low insulin because I wasn’t eating carbohydrates, and the protein I consumed wasn’t insulinogenic enough."

While some diabetics report improved blood sugar control on the carnivore diet, its effects vary based on individual metabolic responses. For non-diabetics, low insulin can lead to hypoglycemia, causing symptoms like dizziness, confusion, a racing heart, and, in extreme cases, seizures or coma. Mild cases can be managed with fast-acting carbohydrates like juice or candy, but severe episodes require medical attention.

His Blood Test Results Showed Concerning Imbalances

Lab tests revealed that his magnesium levels were low, while his sex hormone-binding globulin (SHBG) was elevated—both potential red flags for long-term health issues.

A magnesium deficiency can cause numbness, tingling, fatigue, nausea, headaches, and muscle cramps. Since cramps often strike at night, low magnesium may also contribute to sleep disturbances.

High SHBG levels indicate an excess of circulating protein in the blood, which can increase the risk of heart disease, osteoporosis, and depression. To counteract these imbalances, introducing more magnesium-rich foods—such as leafy greens, nuts, beans, and yogurt—could be beneficial.

He Felt Cold All The Time

Electrolyte imbalances and metabolic disruptions can even affect body temperature, which Dr. Saladino experienced firsthand. "I was always cold,"he shared in his YouTube video.

Upon testing his thyroid function, he discovered that his total T3 and free T3 hormone levels were "not ideal." These hormones regulate metabolism, and low levels can slow down metabolic processes, leading to cold intolerance.

Headaches are one of the most common health complaints and are often caused by stress, lack of sleep, dehydration, excessive screen time, skipped meals, or other lifestyle factors. While most headaches are benign, experts said that frequent or unusual headaches should not be ignored, as they may signal an underlying medical condition that requires evaluation.

The experts told HealthandMe that paying attention to changes in headache frequency, pattern, and associated symptoms can help identify when medical attention is necessary.

Increasing Frequency Is a Warning Sign

According to Dr. Rajneesh Kummar, Vice Chairman & Unit Head, Neurology, Max Super Speciality Hospital, Dwarka, one of the most common concerns is increasing frequency.

“If someone who previously experienced occasional headaches starts getting them several times a week or finds that painkillers are needed more often than before, it is worth getting evaluated,” he told HealthandMe.

“People should seek medical attention if they have headaches more than 10 to 15 days a month, if the headaches are getting worse, or if they are beginning to interfere with work, daily activities, or quality of life,” added Dr. Praveen Gupta, Chairman, MAIINS, Marengo Asia Hospitals, Gurugram. He also noted that medication-overuse headaches can result from taking painkillers regularly, leading to a cycle of recurrent pain.

Watch For Changes In Headache Pattern

A change in the pattern of headaches should not be ignored. Dr. Kummar said a headache that feels different from what a person has experienced in the past, particularly after the age of 50, deserves medical attention. Headaches that wake a person from sleep, are worse in the early morning, or are associated with vomiting should also be assessed further.

Dr. Gupta advised prompt medical evaluation for people over the age of 50 who develop a new type of headache. He also recommends seeing a doctor if a person has a history of cancer, a weakened immune system, or develops a headache after a head injury.

Symptoms That Need Immediate Medical Attention

The neurologists highlight several "red flag" symptoms that require urgent medical assessment. They advised immediate consultation if a headache is accompanied by

• weakness on one side of the body,
• difficulty speaking,
• double vision,
• confusion, seizures,
• loss of consciousness,
• Numbness
• balance problems

Not Every Headache Is a Brain Tumor

Dr. Kummar stated that many people worry that every headache is related to a brain tumor or another serious brain disorder. Fortunately, this is rarely the case.

However, persistent or unusual headaches should not be self-diagnosed, and timely consultation helps identify the cause and ensures appropriate treatment before the problem begins affecting quality of life, the expert said.

Early Diagnosis Key

Dr. Gupta told HealthandMe that early diagnosis can help manage common neurological disorders such as migraines, cluster headaches, and chronic tension-type headaches. A thorough history, neurological examination, and imaging studies, when appropriate, can help determine the cause.

The experts emphasize that if headaches are becoming more frequent, changing in patterns, or affecting daily life, it is time to consult a neurologist. Early diagnosis can provide relief, prevent complications, and improve overall quality of life.

Several recent studies suggest that older adults who receive the shingles vaccine may be less likely to develop dementia, a condition affecting more than 57 million people worldwide.

Shingles is a painful viral infection caused by the reactivation of the varicella-zoster virus (VZV), which can remain dormant after chickenpox and later trigger a blistering rash and severe nerve pain.

Shingrix Vaccine And Reduced Dementia Risk

A June 2026 study published in the Annals of Internal Medicine suggests that one in 17 dementia cases could potentially be prevented through shingles vaccination.

Researchers at Brown University found that older adults who received the recombinant shingles vaccine (Shingrix) after a stay in a skilled nursing facility had a 24% lower risk of being diagnosed with dementia over four years than those who were not vaccinated.

The study analyzed Medicare and health records from more than 500,000 adults aged 66 and older admitted to skilled nursing facilities. Researchers compared those who received at least one dose of Shingrix with those who remained unvaccinated.

“A lot of previous studies with similar results focused on an older vaccine,” said study author Kaley Hayes, an assistant professor at Brown University’s School of Public Health.

“This study looks at the newest vaccine only in an older, vulnerable adult population who were not up to date with shingles vaccination and are at a very clear clinical point in care: entering a skilled nursing facility.”

The findings add to growing evidence linking shingles vaccination with a lower risk of dementia.

How Does The Vaccine Protect The Brain?

Researchers believe the vaccine may help protect the brain by preventing shingles and the inflammation caused by the virus.

Shingles can cause a “war zone” of inflammation in the brain, said Dr. Jennifer Pauldurai, the medical director of the Inova Brain Health and Memory Disorders Program in Northern Virginia, NBC News reported.

It’s not that the shingles vaccine itself is a “magic pill,” Pauldurai said.

Rather, the vaccine guards against the disease, which is known to disrupt brain health.

Evidence from Wales, Australia, and Canada

The latest findings add to a growing body of international research.

A study involving more than 282,000 older adults in Wales, published in Nature in 2025, found shingles vaccination was associated with a 3.5% lower absolute risk of dementia over seven years.

Another study of more than 101,000 older adults in Australia, published in the Journal of the American Medical Association in 2025, found vaccine eligibility was associated with a 1.8% lower dementia risk over 7.4 years.

Similarly, a study involving more than 232,000 older adults in Canada, published in The Lancet Neurology in 2026, linked shingles vaccine eligibility to a 2% lower dementia risk over 5.5 years.

Shingles: Early Warning Signs

After a person recovers from chickenpox, the VZV virus remains dormant in nerve cells and can become active again years or even decades later, particularly when the immune system weakens.

Older adults and people with weakened immune systems are at the highest risk of developing shingles.

According to the NHS, shingles often starts with:

• Burning, tingling, itching, or pain on one side of the body
• Headache or feeling generally unwell
• A blistering rash that develops within a few days, most commonly on the chest or abdomen

When To See A Doctor

Seek prompt medical attention if:

• The rash appears on or near the eye
• The pain is severe or rapidly spreading
• You have a weakened immune system
• You are pregnant
• Symptoms are worsening quickly

From bone smashing to black market peptides, the modern push to “optimize” the male body increasingly runs through human endocrinology, often without a doctor anywhere in the loop.

A Trend That Outgrew Its Origins

Looksmaxxing began on incel forums that blamed romantic failure on fixed facial geometry. That ideology has since spread to TikTok and Instagram, stripped of some of its uglier language but keeping its core premise: a man’s body can and should be engineered, whatever the cost. What started as a fringe belief system now functions as mainstream influencer content with millions of followers.

Clinicians split the practice into softmaxing (sleep, skincare, fitness, mostly harmless) and hardmaxxing, which branches into two wings: mechanical (bone smashing, jaw implants, leg lengthening) and pharmaceutical (unsupervised testosterone, anabolic steroids, SARMs, and peptides marketed as growth hormone substitutes). The pharmaceutical wing is growing fastest, and it sits squarely in endocrinology’s territory.

What These Drugs Actually Do

The body regulates testosterone through a feedback loop running from the hypothalamus to the pituitary to the testes. Flood that system with outside testosterone or anabolic steroids, and it shuts down its own production, taking fertility down with it. SARMs were built to act on muscle and bone while sparing the prostate, but none are approved for human use, and the versions sold online are unregulated and inconsistently dosed. Peptides like ibutamoren (MK-677) stimulate the body’s own growth hormone release. The mechanism sounds gentler, but few have completed real clinical trials for the uses they are marketed for.

The Documented Harms

Anabolic steroids:

● Testicular atrophy and infertility from HPG axis suppression

● Gynecomastia, from testosterone converting to estrogen

● Hepatotoxicity, especially with oral forms

● Psychiatric effects at high doses, including mood instability

SARMs:

● Liver injury, including cholestatic jaundice in black market cases

● Dose-dependent suppression of natural testosterone production

● Elevated liver enzymes, reduced HDL cholesterol

Across the board:

● Elevated hematocrit, raising clotting risk if unmonitored

● Adrenal suppression and disruption of corticosteroid and DHEAS production: exogenous androgens interfere with the hypothalamic-pituitary-adrenal axis, blunting the adrenal gland’s output of cortisol and dehydroepiandrosterone sulphate (DHEAS). The result is impaired stress response, fatigue, and hormonal dysregulation that persists well after the substance is stopped.

● Elevated blood pressure and increased cardiac sympathetic drive: anabolic agents raise systolic pressure and heighten sympathetic nervous system activity in the heart, accelerating resting heart rate and increasing myocardial oxygen demand. Over time, this contributes to left ventricular hypertrophy and raises the risk of arrhythmia.

● Unreliable contents: labels rarely match what is actually in the product, and contamination or substitution is common enough that toxicology reports periodically turn up drugs users never intended to take.

The Mechanical Risks

Bone smashing has no basis in orthopedic science. Bone remodels under sustained load, not blunt trauma, which produces fractures, hematomas, and sometimes permanent damage. Cosmetic jaw implants and leg lengthening are legitimate procedures in the right clinical context, but carry the same surgical risks, infection, nerve damage, long recovery, without the medical justification that normally accompanies them.

The pharmaceutical track carries its own structural toll: supraphysiological androgen levels accelerate calcification in tendons and menisci, reducing their elasticity and load-bearing capacity. Meniscal and tendon calcinosis increases the risk of tears and joint instability, often in the absence of any acute injury. Athletes who stop using these compounds may find the damage is already done.

A related danger runs alongside both tracks. Some men adopt extreme dieting, dehydration, or fasting protocols purely to sharpen jaw and cheekbone definition before photos. The behavior carries the same physical risks as any restrictive eating disorder, yet it rarely gets recognized or treated as one, since it is framed online as discipline rather than disorder.

Why Now

Gallup polling found that roughly a quarter of young American men report frequent loneliness, a notably higher rate than young women. Online communities built around appearance fill that gap with something that looks like belonging, even though the content itself runs on comparison and self-criticism.

TikTok’s own data illustrate how fast the trend has moved: searches for bone smashing and related terms ran in the hundreds of thousands per day in early 2026 and climbed into the millions within a month, before the platform restricted the content. Marketing has kept pace too: one UK survey found nearly a third of 16 to 25-year-olds see SARM ads on social media weekly.

What Legitimate Treatment Looks Like

TRT for confirmed hypogonadism, diagnosed through repeat morning bloodwork and monitored over time, is genuinely effective medicine. That is a different undertaking entirely from a eugonadal man sourcing hormones or peptides online to chase a feeling, with no diagnosis and no monitoring. The same distinction applies to surgery: a qualified surgeon’s evaluation is not the same as a procedure booked off a forum recommendation.

The Bottom Line

None of this is an argument against fitness or grooming, and most softmaxxing is harmless. The danger lies in a narrower set of behaviors: fracturing healthy bone, importing unregulated hormones, chasing a standard that keeps moving regardless of what is achieved.

Endocrinologists studying this are not against masculinity or ambition about one’s appearance. They are arguing that hormonal systems deserve the same evidence-based caution as any other organ system, and that distinction matters more now that these behaviors are still treated as cultural curiosities rather than the clinical concerns they actually are. A blood test and a doctor’s judgment remain better tools than a forum thread and a vial of unknown origin.
