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.

America's falling birth rate is often reported with concerns like shortage of labour, a growing aging population, and slower population growth. But another major consequence is unfolding within the healthcare system that is going unnoticed.
As fewer women have children and more delay pregnancy, women's healthcare is evolving beyond maternity care to address changing health needs.
According to the latest data from the U.S. Centers for Disease Control and Prevention (CDC), 3.63 million babies were born in the United States in 2024, a slight increase from 2023.
However, the general fertility rate fell to a record-low 53.8 births per 1,000 women aged 15 to 44, marking the lowest level ever recorded.
One of the biggest changes is maternity care. With fewer births being reported, hospitals, particularly in rural communities, are struggling to keep labour and delivery departments financially viable.
The problem has contributed to the rise of a maternity care challenge where pregnant women have limited or no access to obstetric services.
The 2024 March of Dimes Maternity Care Deserts Report found that more than one in three U.S. counties lack a single obstetric clinician or birthing facility, leaving millions of women with reduced access to prenatal and delivery care.
Women living in these areas are more likely to receive inadequate prenatal care and experience higher rates of preterm birth.

At the same time, healthcare providers are broadening their focus beyond pregnancy. Women today are delaying childbirth, having fewer children, or choosing not to become parents altogether.
As life expectancy increases, demand is growing for services related to menopause, cardiovascular disease, osteoporosis, pelvic floor disorders, mental health, and healthy aging.
The shift also explains why fertility care is expanding despite declining birth rates. As more Americans postpone parenthood into their late 30s and 40s, many require fertility evaluations, egg freezing, or in vitro fertilization (IVF).
Rather than indicating more births, the growing use of assisted reproductive technology reflects changing reproductive timelines.
An aging female population is also changing healthcare priorities. Older women face a higher risk of chronic diseases such as heart disease, diabetes, osteoporosis, and dementia, increasing the need for preventive care and long-term disease management.
Health systems are investing more in menopause clinics, wellness programs, and other women's health services.
America's falling birth rate is therefore reshaping far more than population statistics. It is redefining women's healthcare, shifting the focus from pregnancy-related care to comprehensive support throughout every stage of life.
On World Population Day, the conversation is not just about how many babies are being born. It is also about ensuring that healthcare evolves to meet the changing needs of women, whether or not they choose to become mothers.

Chai and pakoras are practically non-negotiable once the rains set in. For a large number of Indians, though, monsoon comes with something less welcome: a blocked nose, itchy eyes, and a "cold" that just won't quit.
Most people write this off as a seasonal cold. It's often not. A large share of the patients I see in July aren't fighting a fresh infection. They're dealing with allergic rhinitis that's been present for months at a manageable level, and monsoon has simply pushed it past a threshold they can no longer ignore.
The scale of this is easy to underestimate. A national study under the Global Asthma Network, which surveyed more than 1.27 lakh children, adolescents, and adults across India, found that close to a quarter of Indian adolescents aged 13 to 14 live with allergic rhinitis. Roughly one in ten adults does too.
Other Indian research puts the overall incidence of allergic rhinitis anywhere between 20 and 30 percent of the population. This isn't a niche complaint. It's one of the more common chronic conditions walking through general practice doors, most of which are simply unnamed.
The same national study found something more concerning: nearly three out of four people who met the clinical criteria for allergic rhinitis had never actually been diagnosed with it. Many had lived with recurring congestion, sneezing, and disturbed sleep for years without anyone connecting the dots.
A separate survey of over 1,600 physicians across India found that while a large share see allergic rhinitis routinely in practice, more than half had never used immunotherapy, one of the few treatments that changes the course of the disease rather than just quieting it temporarily.
Indian allergen-testing data show a clear rotation of triggers through the year: dust mites dominate winter, pollens dominate summer, and fungal and insect allergens rise sharply once the rains set in.
The reason is straightforward. Once relative humidity in a city climbs past 70 percent, which happens routinely through the monsoon, fungal spores and dust mites both multiply fast. Waterlogging pushes fungal spore counts up further. A damp curtain or a mattress that never quite dries between showers becomes a long-term allergen source that outlasts any single rainy day.
Allergic skin and eye conditions tend to flare with the same seasonal humidity and allergen load as allergic rhinitis, and in practice, they rarely show up in isolation. A patient with monsoon-triggered nasal symptoms is worth a closer look for coexisting asthma, eczema, or conjunctivitis, simply because in the Indian patient population, these conditions travel together more often than not.
For anyone with a known allergic condition, a few habits make a real difference once the rains arrive:
Monsoon doesn't create new allergy patients. It reveals how well the existing ones are actually being looked after.

Even a mild case of COVID-19 may trigger long-lasting eye problems, with new research revealing that persistent inflammation and nerve damage could be responsible for symptoms that standard eye tests often fail to detect.
The study, led by researchers at Linköping University in Sweden and published in Nature Communications, sheds light on why some COVID-19 survivors continue to experience debilitating vision issues months or even years after infection.
The research began after people who had recovered from mild COVID-19 sought medical help for persistent eye complaints. Many reported:
Many participants said the condition significantly disrupted their daily lives, preventing them from working or continuing their education.

Researchers evaluated 100 people who developed eye problems after mild COVID-19 but had never been hospitalized. Their symptoms had persisted anywhere from three months to three years.
The findings were compared with those of 32 people who had recovered from mild COVID-19 without developing eye symptoms.
Using advanced imaging and laboratory techniques, researchers identified several abnormalities that conventional eye exams failed to detect.
The study found evidence of:
Lead author Petros Moustardas, senior research associate at Linköping University, said the findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction.

One of the most common complaints among participants was extreme sensitivity to light. Researchers found that their pupils were allowing too much light into the eyes because of impaired nerve control.
This abnormal pupil function was also associated with:
The study also identified impaired coordination between the two eyes.
Some participants developed adult-onset strabismus—commonly known as crossed eyes—a condition that is rare in adults.
Researchers believe this occurred because COVID-19 affected the nerves responsible for controlling eye muscles.
Because routine eye tests often miss these abnormalities, the research team developed two diagnostic models.
The first relies on specialized ophthalmic tests available at advanced eye clinics, while the second combines these examinations with tear fluid protein analysis to improve diagnostic accuracy.
Researchers hope these models will help doctors recognize COVID-related eye syndrome earlier and pave the way for future treatments.
"We found that the problems experienced by those affected were not detectable by standard tests. We had to perform specialised examinations to detect deviations. The puzzle pieces then fell into place, and we found explanations for the symptoms," said Neil Lagali, professor of experimental ophthalmology at Linköping University.
He added that while the findings provide important clues about how COVID-19 affects the eyes, more research is needed to develop effective treatments for those living with persistent vision problems.
