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.
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.

Over 57 million people worldwide live with dementia, causing 36.3 million disability-adjusted life years (DALYs) and ranking as the seventh leading cause of death. But when it comes to dementia, memory loss is often the first symptom that comes to mind.
While forgetting birthdays or losing keys are commonly considered early warning signs of dementia, this may not always be the case.
Experts say a person can remember every birthday and anniversary and still have dementia.
“Dementia may not begin with memory loss. It can begin with smell, language, personality or navigation,” Dr Priyam Bordoloi, an internal medicine resident from Assam, said in a post on the social media platform X.
1. Loss Of Smell: When Coffee Stops Smelling Like Coffee
Dr Priyam noted that loss of smell can be an early sign, but it is often overlooked because it may be attributed to a viral illness, sinus disease, smoking, medicines or a head injury.
“Persistent, unexplained smell loss may also be an early clue to Parkinson’s disease or dementia with Lewy bodies,” he added.
2. Everyday Words Start Disappearing
It is not simply an occasional tip-of-the-tongue moment. “In primary progressive aphasia, word-finding, grammar or comprehension may worsen while recent memory stays intact,” Dr Priyam noted.
3. The Family Says, “They Are Not The Same”
Changes in personality or behaviour may sometimes appear before memory problems.
“In behavioral-variant frontotemporal dementia, apathy, impulsiveness, loss of empathy or poor judgment may come before memory loss,” Dr Priyam said.
4. A Familiar Route Suddenly Feels New
Families may notice navigation problems even when a person has no obvious memory complaints. “Families ask me, ‘He has driven there for 20 years. How did he get lost?’ When it repeats, I look beyond forgetfulness,” Dr Priyam said.
He noted that visuospatial dysfunction can appear early in dementia with Lewy bodies or posterior cortical atrophy.
Dr Parveen Yograj, a general surgeon from Jammu, added that one unusual symptom alone means little.
"A new, persistent and progressive pattern that disrupts daily life and is noticed by loved ones is what demands attention," he said on X.
How Can Dementia Risk Be Reduced?
Dr Yograj said several lifestyle measures may help protect brain health and reduce the risk of cognitive decline.

Organ transplantation can offer patients with end-stage organ failure a new opportunity for a longer, healthier, and more independent life. However, transplantation is not the end of treatment—it marks the beginning of a lifelong commitment to maintaining the health and function of the transplanted organ.
Successful long-term outcomes depend on close collaboration between the organ recipient, living donor, transplant team, and family. Regular medical follow-up, adherence to prescribed medications, a healthy lifestyle, and early recognition of warning signs are essential for both recipients and living donors.
For most solid-organ transplant recipients, lifelong immunosuppressive therapy is required to prevent the immune system from attacking the transplanted organ.
Medications such as tacrolimus, cyclosporine, mycophenolate, corticosteroids, and other immunosuppressive agents may be prescribed depending on the type of transplant and the individual patient's condition.
Recipients should:
• Take medications exactly as prescribed and at the recommended times.
• Never stop or reduce immunosuppressive medication without consulting the transplant team.
• Avoid missing doses.
• Inform their transplant physician before starting any new medication.
Even seemingly minor changes in medication can affect drug levels and may increase the risk of acute or chronic rejection.

Regular follow-up with the transplant team is an essential component of lifelong transplant care.
Depending on the transplanted organ and individual circumstances, monitoring may include:
• Kidney and liver function tests
• Complete blood counts
• Immunosuppressive drug levels
• Blood pressure and blood glucose monitoring
• Urine examination in kidney transplant recipients
• Imaging or other investigations when clinically indicated
These evaluations help detect rejection, infection, medication toxicity, or deterioration in graft function at an early stage, sometimes before symptoms become apparent.

Transplant recipients should promptly contact their transplant team if they develop symptoms such as:
• Unexplained or persistent fever
• Chills or significant weakness
• Reduced urine output, particularly after kidney transplantation
• Swelling or sudden weight gain
• Breathlessness or persistent cough
• Persistent pain over the transplant site
• Persistent vomiting or diarrhoea
• Unexplained changes in blood pressure or blood sugar
Because immunosuppressive medications reduce the body's immune response, infections may develop more easily and may sometimes present with subtle symptoms. Early medical assessment is therefore important.
Transplant recipients are more susceptible to infections, particularly during periods of intensive immunosuppression.
Important preventive measures include:
• Practising regular hand hygiene
• Avoiding close contact with individuals who have contagious infections
• Following appropriate food-safety precautions
• Drinking safe and hygienic water
• Maintaining good personal hygiene
• Keeping vaccinations up to date as advised by the transplant team
• Seeking medical advice promptly if symptoms of infection develop
Recipients should also follow the specific infection-prevention recommendations provided by their transplant centre.
A balanced and nutritious diet is an important component of long-term transplant health.
Recipients should aim to:
• Maintain a healthy body weight
• Eat a balanced diet rich in vegetables, fruits, whole grains, and appropriate sources of protein
• Maintain adequate hydration unless fluid restriction has been advised
• Limit excessive salt, sugar, and processed foods
• Exercise regularly according to their medical condition and physician's advice
• Avoid smoking and tobacco products
• Avoid excessive alcohol consumption
Certain foods, supplements, and herbal preparations may interact with immunosuppressive medications. No dietary supplement, herbal preparation, or over-the-counter medication should be started without discussing it with the transplant team.
Living organ donation is a remarkable act of generosity. However, protecting the donor's long-term health remains the highest priority.
After donation, the donor should remain under appropriate medical supervision and follow the recommendations of the transplant and surgical team.
The recovery period varies depending on the type of donation and the individual's overall health.
Donors should:
• Follow wound-care instructions carefully.
• Take prescribed medications as directed.
• Get adequate rest during the initial recovery period.
• Gradually resume physical activity as advised.
• Avoid strenuous exercise and heavy lifting until medically cleared.
• Return to work and normal activities progressively.
The recovery process should be individualized rather than based solely on a fixed timeline.
Most carefully selected kidney donors can lead healthy, active lives with a single functioning kidney.
Long-term health recommendations include:
• Maintaining a healthy body weight
• Exercising regularly
• Eating a balanced diet
• Staying adequately hydrated
• Avoiding tobacco
• Avoiding unnecessary use of potentially kidney-toxic medications, particularly certain painkillers such as NSAIDs
• Monitoring blood pressure
• Periodically checking kidney function and urine as recommended
Living donation should never mean that donors stop looking after their own health. The donor's well-being remains a lifelong priority.
Any new or persistent symptoms should be reported to a healthcare professional.

Transplantation and organ donation can have a significant emotional impact on both recipients and donors.
Recipients may experience anxiety related to rejection, medication, financial concerns, or the uncertainty associated with transplantation. Living donors may also experience emotional changes during the recovery period.
Maintaining open communication with family members and the transplant team can be extremely helpful. If persistent anxiety, depression, sleep disturbances, or emotional distress develops, professional psychological or psychiatric support should be sought.
The success of organ transplantation depends not only on the surgical procedure but also on long-term post-transplant care.
For recipients, medication adherence, regular monitoring, infection prevention, and a healthy lifestyle are essential to preserving graft function.
For living donors, appropriate postoperative recovery, long-term health monitoring, and healthy lifestyle practices help ensure that they continue to live healthy and fulfilling lives after donation.
The transplant may be a single surgical event—but maintaining the gift of life is a lifelong journey.
With appropriate medical supervision, adherence to treatment, healthy lifestyle choices, and timely attention to warning signs, organ recipients can protect the health of their transplanted organ, while living donors can continue to enjoy a healthy and active life after their selfless contribution.

Organ donation is one of the most generous gifts a person can give. Age, diabetes, hypertension or other medical conditions do not automatically rule out organ donation, doctors said on World Organ Donation Day.
Observed on August 13 every year, World Organ Donation Day aims to raise awareness about the need for organ and tissue donation and honour donors and their families.
Dr. Umesh Gupta, Director and HOD, Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, told HealthandMe that organ donation can be considered when brain function is permanently lost and cannot be restored.
Brain death occurs when all functions of the brain and brainstem have permanently stopped.
“Brain death is different from a coma or a prolonged unconscious state. In brain death, the person cannot regain consciousness or breathe independently. Mechanical support may continue to keep the heart beating and preserve the condition of organs for a limited period, which is why organ donation can be considered,” he said.
Depending on the donor’s medical condition, organs such as the heart, liver, kidneys, lungs and pancreas may be suitable for transplantation.
Age alone does not rule out organ donation. Eligibility is assessed individually by the transplant team.
Doctors evaluate:
Can People With Diabetes or Hypertension Donate?
People with well-controlled diabetes or hypertension may still be eligible to donate certain organs or tissues, said Dr. Shailesh Chandra Sahay, Senior Director - Urology, Kidney Transplant, Robotic Surgery, Max Super Speciality Hospital, Patparganj.
Modern transplantation practices allow doctors to assess each organ individually rather than excluding a donor solely because of age or a particular diagnosis.
Every potential donor deserves a medical evaluation. An organ that may appear unsuitable to a person could ultimately give another patient a second chance at life.
Blood group compatibility is an important consideration in organ transplantation.
“A blood group O donor typically donates to O recipients, while AB recipients can receive organs from all ABO blood groups in many transplant settings,” Dr. Saurabh said.
However, compatibility involves more than blood type. Doctors also assess:
