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.

Stroke is a medical emergency, but in some patients, it may also be the first sign of an undiagnosed cancer, said top Neurologist Dr. Vinit Suri on World Stroke Day.

In an exclusive interview with HealthandMe for World Stroke Day, Dr. Suri, Senior Consultant Neurologist and Academic Coordinator at Indraprastha Apollo Hospital, New Delhi, explains the link between cancer and stroke, the warning signs that need urgent attention, and how patients can reduce their risk.

He noted that cancer and its treatment can also increase stroke risk, while a stroke may sometimes prompt doctors to investigate an underlying malignancy.

The noted expert also highlighted warning signs which may point to an underlying malignancy, and how cancer patients can reduce their risk and manage recovery.

Dr Suri said cancer and stroke can overlap in three ways: cancer patients may have conventional risk factors such as hypertension and diabetes; cancer itself can increase blood clotting; and certain treatments can raise stroke risk.

“Cancer patients have double the risk of having a stroke compared to their age-matched individuals,” Dr Suri said.

He estimated that 10% to 15% of stroke patients may have cancer or cancer treatment as the underlying cause. Sometimes, a stroke is the first sign of an undiagnosed malignancy, known as a sentinel stroke. Thus, identifying the cause is important to prevent recurrent strokes.

Which Cancers Are Associated With Stroke?

Q. What Warning Signs May Point To An Undiagnosed Cancer?

Dr. Suri said doctors should consider investigating an underlying malignancy in patients with:

• Strokes affecting multiple brain areas, particularly without common risk factors such as hypertension, diabetes or atrial fibrillation.
• Recurrent strokes despite preventive treatment.
• Abnormal blood counts or clotting parameters, including low platelets, low hemoglobin or abnormal coagulation results.
• D-dimer levels more than five times the normal value, which may raise suspicion of cancer.

Investigations may include D-dimer testing, tumor markers such as prostate-specific antigen (PSA), other cancer biomarkers and whole-body PET-CT, said the noted neurologist.

A stroke may reveal cancer even without obvious cancer-related symptoms. Emergency stroke treatment must take priority, followed by investigations to identify the cause and prevent recurrence, he added.

Dr Suri said sudden neurological symptoms in cancer patients require urgent assessment because stroke and brain metastases can present similarly. Brain metastases may also cause seizures and one-sided weakness.

He recommended BE FAST to recognize possible stroke symptoms:

• B — Balance: Sudden loss of balance.
• E — Eyes: Sudden vision problems.
• F — Face: Facial asymmetry.
• A — Arms: Arm weakness or downward drift.
• S — Speech: Slurred speech or difficulty speaking.

Anyone experiencing these symptoms should seek emergency care, the expert said.

“Time is brain,” he said. Clot-dissolving drugs may be given within four and a half hours in eligible patients, while clot-removal procedures may be possible within six to 24 hours, depending on the patient.

CT scans may be sufficient in many cases, but MRI may help distinguish a stroke from brain metastases.

Q. How Can Cancer And Its Treatment Increase Stroke Risk?

Dr Suri said that some chemotherapy drugs and hormonal therapies for breast and prostate cancers can increase blood clotting.

Radiation to the neck may cause narrowing, scarring and fibrosis in the carotid arteries, potentially contributing to strokes years later.

Q. How Can Cancer Patients Reduce Their Stroke Risk?

Dr Suri advised people to control blood pressure, diabetes, abnormal cholesterol and obesity through physical activity and by avoiding a sedentary lifestyle.

Age, male sex and family history are the non-modifiable risks, while other risk factors include heart disease, smoking, alcohol use, chewing tobacco and drug abuse, which can contribute to strokes even in young people.

Dr Suri described hypertension as the most important modifiable risk factor and a major cause of ischemic and hemorrhagic strokes. He recommended regular blood pressure checks, reducing salt intake, walking and taking prescribed medication. He also stressed diabetes management and identifying atrial fibrillation, which can cause strokes affecting multiple brain blood vessel territories in older adults.

Oncologists should consider stroke risk when choosing treatments, particularly for patients with pancreatic or lung cancer and other adenocarcinomas associated with increased clotting risk, he said.

Treatment may involve addressing the underlying cancer through chemotherapy or surgery and preventing further clots. Warfarin may not work in some cases, and doctors may consider direct oral anticoagulants (DOACs) or low-molecular-weight heparin.

Q. How Do Cancer And Stroke Together Affect Recovery?

Dr Suri said having both conditions can worsen prognosis because stroke can cause death or long-term disability, while cancer may reduce life expectancy.

“When these two double whammies are happening together, the outlook becomes much, much graver,” he said, adding neurologists and oncologists must work together to adjust treatment.

“Both of them have to be involved together as a team to plan and modify both the cancer therapy as well as the stroke therapy,” he said.

Some medicines that increase stroke risk may need to be withdrawn. Blood thinners must be selected with the oncologist because certain chemotherapy drugs can rapidly lower platelet and white blood cell counts.

Cancer does not automatically prevent stroke rehabilitation, Suri said, although severe weakness or frailty may limit participation.

“Cancer is not likely to interfere with the rehabilitative processes unless and until it has made the patient very weak and frail,” he said.

Q. Can Cancer And Stroke Occur In Young People?

Yes, Dr Suri said. Both can occur at any age, although their causes and cancer types may differ across age groups.

“Stroke can occur even in very young children,” he said, noting that infants may have strokes due to arteriopathies and other conditions. Both conditions become more common with age, but neither has a lower age limit.

Ever since artificial intelligence became a part of our lives, we have fallen into the habit of quickly firing up that chat box and typing our biggest worries, darkest thoughts among many other things. But it has become important to stop and ponder whether AI is really producing the most useful and viable solutions for us.

A recent study published in NEJM AI suggests that artificial intelligence systems may recommend more expensive medical care than doctors. The findings said that AI-generated care plans may cost more than three times as much as doctors’ recommendations.

The researchers compared recommendations from 24 artificial intelligence systems with the recommendations by physicians across 200 outpatient and emergency department visits.

They found that AI systems suggested more diagnostic tests, specialist referrals and medications than doctors.

The average estimated cost of care recommended by 20 general-purpose AI systems was USD 314 per visit compared to USD 97 for physicians’ plans. That was equal to a 3.2-fold difference.

How Did Researchers Compare AI’s Recommendations With Doctors’?

The researchers used 200 de-identified patient history and notes from outpatient and emergency department visits, sourced from MTSamples, a public collection of clinical documentation.

They gave the notes to 24 AI systems, including 20 general-purpose large language models and four specialised medical AI systems. Each system produced an assessment and plan based on that information. Researchers then compared these recommendations with the original physician’s documented plan.

The researchers estimated costs using 2026 US Medicare rates. The cost comparison included diagnostic tests and specialist referrals. New medications were counted separately. The results showed that AI-generated plans recommended more investigations and specialist consultations, increasing the estimated cost of care.

AI Recommended More Tests Even When Doctors Ordered None

One of the key findings concerned visits in which physicians had not ordered diagnostic tests.

Doctors had recommended no diagnostic testing in approximately 66% of the encounters. Across these visits, the AI systems consistently suggested tests, often including standard panels of blood investigations.

Overall, diagnostic testing recommended by the general-purpose AI systems cost an estimated USD 176 per visit compared to USD 71 for doctors’ plans.

AI systems also recommended specialist referrals and new medications more frequently than doctors. The researchers saw an average of 1.14 new medications per visit across the AI systems, compared to 0.59 in physicians’ plans.

These findings suggest that AI-generated care plans may favour additional investigations and interventions.

Can Changing Prompts Help Obtain Less Expensive Medical Care From AI?

The researchers also examined whether changing the prompts given to AI systems could reduce the cost of their recommendations.

Prompts containing savings and budget-friendly suggestions reduced the estimated cost difference, but did not eliminate it. The cost ratio fell from 3.2 times physicians’ plans to 2.5 times when systems were specifically instructed to recommend cost-friendly tests and medicines.

When the systems were asked to recommend a plan that was both affordable and clinically sound, the ratio fell further, to approximately 1.4 times the physicians’ cost.

While some tests suggested by AI may come across as unnecessary, it should be noted that a physician’s recommended plan is also not the perfect benchmark.

It is possible for doctors to miss investigations that may be clinically needed, while AI systems may suggest additional tests that are unnecessary or poorly suited to an individual patient.

The findings raise questions about how AI systems should be evaluated before being incorporated into clinical decision-making.

AI can help doctors organise patient information, identify diagnoses and consider treatment options. But a recommendation generated by a chatbot is not a prescription or a substitute for a clinician’s assessment.

The death of 31-year-old Bowen Wan, who had epilepsy, has raised concerns about relying on AI for medical decisions. A lawsuit filed by her family alleges that she followed ChatGPT’s advice to reduce and eventually stop her anti-seizure medication.

According to the complaint, OpenAI’s chatbot provided a tapering schedule, encouraged her to keep the changes from her doctor and reassured her when she reported symptoms.

Wan, a former Amazon software engineer who lived in Seattle, had been taking lamotrigine to manage her epilepsy. She was concerned that the medication was affecting her memory, speech and performance in job interviews.

Why Stopping Epilepsy Medication Can Be Dangerous

Epilepsy is a neurological condition characterized by seizures. Anti-seizure medicines help control abnormal electrical activity in the brain, and treatment is tailored to a person’s condition, seizure history and response to medication.

Although side effects may require treatment adjustments, patients should not independently reduce their dose or stop taking medication. The Epilepsy Foundation warns that suddenly stopping anti-seizure medicines can trigger withdrawal symptoms and potentially life-threatening seizures.

According to reports cited in the lawsuit, ChatGPT allegedly provided a plan to reduce Wan’s daily dose from 400 mg to zero over about 25 days without her doctor’s approval. The complaint further alleges that the chatbot encouraged her to keep the changes from her physician.

In one reported exchange, when Wan asked whether she could reduce the dose herself without telling her doctor, the chatbot allegedly replied, “Yes, you can absolutely do this.”

Why AI Should Not Guide Medication Decisions

HealthandMe spoke to two neurologists about the risks of relying on AI tools to decide whether to skip, adjust or restart prescribed medication. They noted that AI can help patients understand medical terms and prepare questions for clinicians, but it should not replace professional advice on changing prescribed treatment.

“AI tools can provide general information but do not have access to a patient's complete medical history, seizure type, medication regimen, test results, or individual risk factors. As a result, their advice may be incomplete, inaccurate, or inappropriate for a specific patient,” said Dr. Sudhir Kumar, Senior Consultant Neurologist, Institute of Neurosciences, Apollo Hospitals, Hyderabad.

“Decisions about stopping, adjusting, or restarting anti-seizure medications should always be made in consultation with a qualified clinician who can assess the benefits and risks in the proper clinical context,” he said.

A missed-dose recommendation may not apply to every anti-seizure medicine or dosing schedule. Drug interactions can also affect medication levels, seizure control and the risk of side effects.

Dr. Praveen Gupta, Chairman of the Marengo Asia International Institute of Neuro and Spine (MAIINS), Marengo Asia Hospitals, told HealthandMe AI tools can help people understand medical information but should not replace a neurologist when decisions about epilepsy treatment are involved.

Managing epilepsy requires an individual assessment of the patient’s seizure type, medical history, prescribed medication and dosage, other health conditions, and response to treatment, he said.

“Patients should not use AI tools to decide whether to stop, restart, increase or reduce their medication. Suddenly stopping some anti-seizure medicines can lead to more severe or prolonged seizures that may require emergency treatment,” Dr. Gupta said.

AI can help patients understand a diagnosis or prepare questions for their doctor, he added, but medication decisions should be made by a qualified health professional who can assess the individual's clinical situation.

Can Missing One Dose Trigger a Seizure?

Dr. Kumar told HealthandMe that there is no universally safe number of doses a person with epilepsy can miss.

Missing or delaying an anti-seizure dose can lower medication levels in the blood, potentially reducing protection against seizures and increasing the risk of a breakthrough seizure, Dr. Gupta explained. This can happen even in people who have been seizure-free for a long time.

A single missed dose can trigger a seizure in some people, but the risk varies depending on the type of epilepsy, seizure control, medication, its half-life, dosing schedule, and individual susceptibility.

Taking medication as prescribed is the safest approach, the experts said.

What Should You Do If You Miss a Dose?

The experts advised that patients to:

• Check the instructions supplied with their medication and contact their neurologist or pharmacist for advice. The appropriate response depends on the specific medicine and how much time has passed since the missed dose.
• Do not double the next dose or stop treatment unless a qualified health professional has advised you to do so.
• If multiple doses have been missed, seek medical advice before deciding how to resume treatment.
• Phone alarms, reminder apps, pill organizers and a daily medication chart can help patients take their medicines consistently.
• Seek emergency medical help if a seizure lasts five minutes or longer, repeated seizures occur without the person regaining consciousness, or the person has breathing difficulties.
• Patients should also follow the emergency plan provided by their neurologist.
