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.

Brain disorders are becoming one of India's fastest-growing public health challenges, said health experts ahead of Brain Day on July 22.
The experts highlighted that an ageing population, rising lifestyle diseases and limited access to specialist care are contributing to an increasing burden of conditions such as stroke, epilepsy, Parkinson's disease, dementia and multiple sclerosis.
Dr. Madhukar Bhardwaj, Director & Head of Department, Neurology, Aakash Healthcare, said neurological disorders have become one of India's most urgent healthcare concerns.
"Neurological disorders are no longer a concern of a small section of the population—they are one of the most pressing emerging healthcare challenges of our time. In a country as vast and diverse as India, with a rapidly ageing population, this is a matter of urgency. What makes the situation even more worrying is the lack of equitable access to care," he said.
According to the World Health Organization's Global Status Report on Neurological Disorders (2025), India faces a severe shortage of neurologists, with the neurologist-to-patient ratio nearly 80 times worse than in high-income countries, leaving specialist care concentrated in major cities.
Experts also highlighted a worrying shift in disease patterns, with strokes increasingly affecting younger people. Dr. Bhardwaj said strokes, once considered a disease of older adults, are now being seen more frequently among people in their 30s and 40s, underscoring the need for greater awareness and prevention.
Doctors identified uncontrolled hypertension, diabetes, obesity, smoking, chronic stress, physical inactivity and poor sleep as major contributors to the rising burden of neurological diseases.
Dr. Rajas Deshpande, Consultant and Head of Neurology, Jupiter Hospital, Pune, said many neurological conditions share common lifestyle-related risk factors.
"Controlling hypertension, diabetes, obesity, smoking and physical inactivity can significantly reduce the risk of stroke and vascular dementia. Prevention deserves as much attention as treatment because many neurological disorders share common modifiable risk factors," he said.
Dr. Bhardwaj stressed that many neurological disorders progress silently, making early diagnosis critical.
"Whether it is stroke, epilepsy, Parkinson's disease or memory disorders, early diagnosis can significantly improve outcomes. Unfortunately, many patients seek specialist care only after the disease has advanced, either because symptoms are ignored or because neurological services are not easily accessible. Greater public awareness and timely referrals are essential," he said.
Experts also emphasized that brain health extends beyond cognition. Dr. Hrishikesh Pai, Consultant Gynecologist & IVF Specialist, Lilavati Hospital Mumbai and Fortis Hospitals Delhi & Chandigarh, said the brain plays a central role in regulating women's reproductive health.
"Brain health plays a critical role in women's reproductive health. The hypothalamus and pituitary gland in the brain regulate the hormonal signals that control menstruation, ovulation, and pregnancy," he said.
He added that chronic stress, neurological disorders, pituitary diseases and certain medications can disrupt hormonal balance, leading to irregular menstrual cycles, infertility and pregnancy-related complications.

As wildfire smoke continues to affect communities across North America and Europe, fertility experts are recommending people undergoing vitro fertilization (IVF) to pay attention to an overlooked factor before embryo implant: air quality.
A new study suggests that exposure to unhealthy levels of air pollution, particularly from wildfire smoke, could significantly reduce the chances of a successful pregnancy after IVF.
Researchers, therefore, recommend discussing the timing of embryo transfer with a fertility specialist when air quality deteriorates.
The study, published in the journal Human Fertility, indicates that air pollution may affect reproductive health.
Between June and July 2023, researchers from Northwell Fertility in New York examined 190 fresh and frozen embryo transfers, when smoke from massive Canadian wildfires caused hazardous air quality across the northeastern United States.
They then compared the rate of successful pregnancies based on the Air Quality Index (AQI) on the day of embryo transfer.
Clinical pregnancy rates were approximately 62% on days with good air quality and 65% on days with moderate air quality.
But when the AQI rose above 100, a level considered unhealthy for sensitive groups; the pregnancy rate dropped to just 27%.
Although only 11 embryo transfers took place on days with unhealthy air quality, the researchers say the findings raise concerns about whether temporary exposure to wildfire smoke could affect one of the most critical stages of IVF.
IVF embryos are created and stored in strictly controlled laboratories, meaning they are protected from polluted air and other contaminants in the environment.
Instead of damaging the embryo, researchers believe that wildfire smoke can affect the woman's body by increasing inflammation and oxidative stress. This could create a less favourable environment for the embryo to implant in the uterus.
Air pollution contaminant, PM2.5, a fine particulate matter, is one of the main pollutants in wildfire smoke. It is minute enough to enter the lungs, bloodstream, and trigger inflammatory responses throughout the body.
Previous studies have already indicated that PM2.5 exposure could cause pregnancy complications and harm fertility.
Dr. Randi Goldman, Program Director at Northwell Fertility and co-author of the study, said the research suggests patients and physicians should consider environmental conditions when planning embryo transfer.

"The embryo is safely protected inside the laboratory. The effect we're seeing is more likely related to how air pollution influences the body before and after embryo transfer rather than the embryo itself," Goldman said.
She opines that patients experiencing severe wildfire smoke or hazardous air quality should discuss whether delaying embryo transfer by a few days could improve the chances of success.
"Patients invest enormous emotional, physical and financial resources into IVF. Delaying treatment is difficult, but when air quality reaches unhealthy levels, it may be worth discussing timing with your fertility specialist," Goldman said.
Adopt a Fertility-Boosting Lifestyle: Eat a balanced diet, exercise daily, and enjoy a healthy BMI. Reduce alcohol intake, do not smoke, and avoid recreational drugs.
Take Key Supplements: Folic acid, CoQ10, and vitamin D can improve egg quality and overall fertility.
Stress Management Is Key: Elevated cortisol levels can affect reproductive hormones. Practice mindfulness, yoga, or acupuncture.
Sleep Well: Aim for at least 7–8 hours of restful sleep to support hormonal balance.
Address Underlying Health Conditions: Conditions such as PCOS, thyroid issues, and endometriosis can interfere with fertility outcomes if left unmanaged.
Start Early, If Possible: The earlier IVF is initiated—especially for women over 35—the better the chances.

The detection of the Omicron RF.5 subvariant in Andhra Pradesh has raised concerns about a possible resurgence of COVID-19 in India. However, health experts say there is no evidence so far that the new sub-lineage causes more severe illness than other recently circulating Omicron variants.
While RF.5 may spread more efficiently, experts stress that the focus should remain on protecting vulnerable groups rather than panicking.
Speaking to HealthandMe, Dr. Aijaz Ilmi, Senior Consultant – Preventive Wellness & Metabolic Diseases, Pacific OneHealth Hospital, said the detection of RF.5 should prompt vigilance, not fear.
"At present, there is no convincing evidence that RF.5 causes more severe disease than other recently circulating Omicron variants, although it may spread efficiently. Ongoing surveillance remains essential, as seen in Telangana."
Dr. Tushar Tayal, Associate Director, Internal Medicine, CK Birla Hospital, Gurugram, added that countries including Singapore have already detected RF.5 without reporting a corresponding rise in hospitalizations, suggesting the variant may be more transmissible but not more severe.

Dr. G.C. Khilnani, Chairman, PSRI Institute of Pulmonary, Critical Care, told HealthandMe that the current outbreak is being driven by the Omicron variant, which generally causes a milder upper respiratory illness than earlier COVID-19 strains.
He said healthy individuals typically experience fever, cough, runny nose and body aches, while the risk of severe disease remains much lower than during previous waves.
"This virus remains confined to the throat, or what we call the oral cavity, and does not traverse to the lungs. Therefore, in a normal healthy individual, it does not cause pneumonia. So, it is not life-threatening in immunocompetent or healthy individuals."
Following four COVID-19-related deaths reported in Andhra Pradesh over the past two weeks, experts said people with weakened immunity continue to face the highest risk of severe illness. This includes cancer patients undergoing chemotherapy, people with uncontrolled diabetes, older adults, those on long-term steroid therapy and people living with HIV/AIDS.
"Most infections are expected to present with mild upper respiratory symptoms such as sore throat, fever, cough, runny or blocked nose, fatigue, headache and body aches," Dr. Ilmi said.
He added that older adults, pregnant women, people with heart, lung or kidney disease, obesity, cancer, diabetes, weakened immunity and those who are inadequately vaccinated remain the most vulnerable to severe COVID-19.

Experts said RF.5 does not appear to cause unusual symptoms. Common signs include:
They advised seeking immediate medical attention if symptoms such as breathlessness, persistent chest pain, confusion or low oxygen levels develop.
India has reported a renewed uptick in COVID-19 cases, with 339 infections recorded between July 1 and July 16, according to the Andhra Pradesh Health Department.
Reported cases during this period include:
Experts said public health guidance has not changed despite the emergence of RF.5. They recommend wearing masks in crowded places, getting tested if symptoms develop, and isolating after a positive test to reduce transmission.
Dr. Khilnani also stressed the importance of early diagnosis, avoiding crowded places while infected, wearing a mask and following proper cough etiquette. He added that people with weakened immunity should be especially cautious, avoid crowded settings and maintain good hand hygiene.
Early testing, adequate hydration, rest and symptomatic treatment remain the cornerstone of management, particularly for high-risk individuals.
