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.

Athletes who spend years training their bodies undergo remarkable physiological changes. Athlete's heart is one of them. It becomes stronger, more efficient, and sometimes even larger. This natural adaptation is known as athlete's heart, a condition that is completely normal in most cases but can occasionally resemble serious heart disease.
Understanding the difference between a healthy athletic heart and an underlying cardiac disorder is crucial, especially as awareness grows around sudden cardiac deaths in young athletes.
HealthandMe spoke to Dr. Ruchit Shah, Interventional Cardiologist at Saifee Hospital, Mumbai, who said, “If a person exercises too much, normally more than 60 minutes in most days of the week for a prolonged period of time, the body's need for oxygen and for blood to supply the oxygen rises significantly. This can often be seen in the very intense training regimens of competitive athletes. The heart muscle responds to this extra demand by getting "conditioned" and thickening with time.”
Just like skeletal muscles that get bigger and thicker and with training and exercise, the heart muscle can get bigger and thicker too.
Athlete's heart is usually characterised by a “conditioned heart rate”. People with athlete's hearts will now show symptoms or serious warning signs and thereby won't need a specific treatment for the condition.

Signs include:
The expert also says that athlete's heart is different from serious cardiac diseases like cardiomyopathies, especially hypertrophic obstructive cardiomyopathy (HOCM).
He says, “HOCM is a serious disease, with heart muscle thickening also occurring and causing the left ventricular cavity to narrow. The left ventricle's outflow tract can also become obstructed from this excessive thickening. Athletes with HOCM have a risk of sudden cardiac arrest and death, unlike athletes with athlete's heart.”
An athlete‘s heart, by itself, is considered a benign physiological adaptation and does not require medical intervention.
However, it becomes important to investigate further if an athlete experiences:
Ignoring these warning signs can delay the diagnosis of potentially serious cardiac conditions. Those who have an athlete’s heart must get periodic cardiac evaluation, do a temporary reduction in training if the diagnosis remains uncertain, and monitor when minor abnormalities are present.
Athlete's heart is proof of the body's extraordinary ability to adapt to sustained physical activity. For most athletes, it represents a healthy, efficient cardiovascular system rather than a medical problem. The challenge lies in distinguishing these normal adaptations from potentially dangerous heart conditions that can look remarkably similar.

Popular GLP-1 medications such as Ozempic, Wegovy, and Zepbound are well established for improving metabolic health, lowering blood sugar and promoting weight loss. These blockbuster drugs are also known to reduce the risk of conditions such as heart disease and type 2 diabetes.
Now, researchers are exploring whether these medications could also help slow biological aging and potentially increase longevity.
A recent US National Institutes of Health (NIH)-backed study, published in the journal Nature, found that Ozempic slowed biological aging in people living with HIV and lipohypertrophy, a condition in which fatty deposits develop under the skin.
People with HIV often experience accelerated aging because of the infection, making them an important group for age-related research, said lead author Dr. Michael Corley, associate professor of medicine at the University of California, San Diego's Stein Institute for Research on Aging, according to The New York Times.
Although the trial was preliminary, Dr. Corley said it "provided us an opportunity to say, hey, is there any signal here that warrants all the hype?"
Experts believe the findings are promising, but stressed that more research is needed.
Dr. Nicolas Musi, director of the Diabetes and Aging Center at Cedars-Sinai, told NYT that because these drugs reduce the risk of diseases associated with aging, they could potentially improve lifespan as well.
"GLP-1 agonists decrease the incidence of diseases that are related to aging and are associated with decreasing life span. One would assume that they're also potentially going to increase life span and be beneficial for longevity," Dr. Musi said.
Researchers also point to the drugs' anti-inflammatory effects. Chronic inflammation is one of the biological processes linked to aging, said Dr. Thomas Blackwell, professor of general internal medicine at the University of Texas Medical Branch in Galveston.
However, scientists caution that there is currently no evidence showing that GLP-1 drugs provide longevity benefits for people who are already metabolically healthy.

Drugs such as Ozempic and Wegovy contain semaglutide, a GLP-1 receptor agonist, while Zepbound and Mounjaro contain tirzepatide.
These medications are approved for the treatment of type 2 diabetes, and some are also approved for chronic weight management.
GLP-1 receptor agonists work by binding to GLP-1 receptors in the body. This increases insulin production in response to food, suppresses glucagon—a hormone that raises blood sugar—and helps regulate blood glucose levels.
GLP-1 (glucagon-like peptide-1) is a hormone naturally produced by the small intestine after eating. It plays several important roles in regulating blood sugar and appetite by:

On Doctors Day, along with celebrating the valuable contribution and role of doctors, it is also important to take a look at what goes on beyond operation theatres and surgical masks. Amid increasing instances of doctors seeking mental health support, we take a look at what is pushing doctors to seek mental health care.
HealthandMe spoke to Neha Cadabam, Senior Psychologist & Executive Director, Cadabam's Hospitals, and Dr. Jagadeesh P.C, Senior Orthopaedic Surgeon and Robotic Joint Replacement at Kauvery Hospitals & Joss Center, about increasing burnout, stress, anxiety, and other mental health issues among doctors in various specialties.
Doctors face grueling work schedules that entail long work hours, demanding patient care, and constant vigilance to provide the best service.
Neha Cadabam explains, “Doctors are often expected to remain composed, resilient, and emotionally available regardless of the circumstances they face. However, the emotional demands at their profession can accumulate over time.”

She also said that long working hours, repeated exposure to suffering and death, difficult clinical decisions, medico-legal concerns, workplace violence, and the constant pressure to avoid errors can create a significant psychological burden.
Dr. Jagadeesh P.C sheds light on how doctors in the orthopedics specialty face constant physical and emotional stress. He says that as orthopedicians mostly handle traumas and accidents, they undergo added stress due to emergencies and constant patient care.
He says, “Surgeons and physicians work in high-pressure environments where critical decisions need to be made quickly, often after long hours in operating rooms, emergency departments, clinics, and wards. The responsibility of restoring mobility, managing trauma cases, handling complications, and supporting patients through recovery can be deeply demanding.”
He also said that doctors frequently work through physical fatigue, irregular schedules, sleep deprivation, and the emotional weight of patient outcomes. In specialties such as orthopaedics, where many cases involve trauma, pain, disability, and long recovery journeys, the responsibility extends well beyond the operating theatre.
According to the experts, doctors are mainly seeking mental health care for:
Neha Cadabam says, “Many doctors find it difficult to acknowledge their own emotional struggles because medicine has traditionally valued endurance and self-sacrifice. Seeking help is often perceived as a sign of weakness when, in reality, it reflects insight and self-awareness.”

In a real-life case, a 38-year-old emergency medicine specialist sought mental health support after years of managing trauma cases, and long shifts led to burnout, anxiety, compassion fatigue and sleep problems.
After psychotherapy and stress management, the doctor reported improved sleep, reduced anxiety, and better work-life balance.
In another situation, a 45-year-old obstetrician and gynaecologist sought help for burnout, chronic stress, and anxiety caused by the demands of high-risk pregnancies, emergency procedures, and medico-legal pressures.
Therapy helped improve emotional wellbeing, sleep, and the ability to disconnect from work outside hospital hours.
Doctors are often seen as symbols of resilience, but the misplaced resilience is taking a toll on their mental health. Acknowledging that doctors experience stress, anxiety, and emotional fatigue is not commentary on their professionalism.
Dr Jagadeesh P.C says, “The well-being of doctors is closely linked to the quality of care they provide. As healthcare systems evolve, there is a growing need to create environments that support the physical and emotional well-being of medical professionals. On Doctor's Day, it is important to recognize not only the dedication of doctors but also the immense pressures they navigate every day while caring for others."
As conversations around mental health continue to gain exposure, experts say supporting doctors' psychological wellbeing should become an integral part of strengthening healthcare systems.
