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.

Taking care of a sick person is a taxing job not many people can fullfill. Patients with mental health issues like dementia require specialized care and not everyone is equipped to handle these situations. Many times, people with dementia have emotional outbursts, difficulty communicating as well as doing normal lifestyle activities. Caring for people with dementia requires a team of people, sometimes 24/7 care with rotations for staff, so that the patient is not left unattended for an extended period of time. However, does this extensive routine affect the caregiver’s health? A new study has found concerning future implications for dementia caregivers.

Caring for someone with dementia might put caregivers at higher risk for their own brain aging and future dementia, a new study suggests. This is largely due to certain lifestyle factors.

Caregivers' Hidden Risk

A recent report from the Public Health Center of Excellence on Dementia Caregiving, released on June 12, found that nearly 3 out of 5 dementia caregivers (59%) have at least one risk factor that increases their chances of developing dementia over time. Even more concerning, about 1 in 4 (24%) have two or more of these risk factors.

Matthew Baumgart, senior vice president of health policy for the Alzheimer's Association, called this analysis a "wake-up call." He noted that caregivers are often so focused on their loved ones that they neglect their own health. This highlights a critical need for public health strategies to support these vulnerable individuals.

Key Risk Factors Identified

Researchers analyzed health data from caregivers across 47 states in 2021 and 2022. They found that caregivers were more likely than the average person to have five things that aren't good for brain health:

Smoking

Caregivers were 30% more likely to smoke. Smoking is bad for your overall health, including your brain.

High Blood Pressure

They were 27% more likely to have high blood pressure. High blood pressure can damage blood vessels, including those in the brain.

Poor Sleep

21% more likely to say they didn't sleep well. Not getting enough good sleep can affect how your brain works and ages.

Diabetes

They had a 12% higher chance of having diabetes. Diabetes can lead to problems with blood flow and brain function.

Obesity

Caregivers were 8% more likely to be overweight or obese. Being overweight is linked to many health problems, including some that affect the brain.

Interestingly, there was one good piece of news: caregivers were actually less likely to be inactive (meaning they moved around more) compared to others. This might be because looking after someone with dementia often involves a lot of moving around.

Younger Caregivers Face Greater Vulnerability

This part focuses on younger caregivers, and the news isn't great for them. The study found that younger people who care for someone with dementia are at an even higher risk.

• 40% more likely to have many of these risk factors at once, compared to other people their age.
• 86% more likely to smoke. That's a huge difference!
• 46% more likely to have high blood pressure.
• 29% more likely to get less than six hours of sleep each night compared to their friends who aren't caregivers.

The researchers explained that knowing which groups of caregivers are most at risk, public health officials can better plan and offer help. Instead of a one-size-fits-all approach, they can create specific programs and resources for the groups that need it most.

A parasite that causes malaria is halted by sickle cells and makes people who carry the sickle cell trait more resistant to the disease. This is why sickle cell trait also occurs more in people who live in tropical and sub-tropical regions where cases of malaria were or still is common.

It comes from the copy of an abnormal sickle or the HBB gene and one copy of the normal HBB gene. The gene is an evolutionary response to malaria, where humans begin to develop an abnormal HBB gene and pass it onto to the next generation.

The "Black Disease"

The earliest documentation of sickle cell symptoms in medical texts could be found from the 1870s. However, it had not been formally identified until in 1910. when the first case was detected in the United States. The first case of sickle cell disease or SCD in the US was in 1904, when Walter Clement Noel, a 20-year-old dental student from Grenada, sought care for anemia at Chicago Presbyterian Hospital, where he met Dr James B Herrick. Dr Herrick was a cardiologist and professor of medicine and he was assigned noel who had experienced recurrent episodes of "muscular rheumatism" and "bilious attacks" over a period of 3 years.

This case was assigned to an intern Dr Ernest E Irons by Dr Herrick. Dr Ernest performed initial blood work on Noel and observed the unusual sickle-shaped red blood cells in the sample under the microscope. This is when Dr Herrick was told about it, leading to him publishing the first documented case study of SCD, titled, "Peculiar Elongated and Sickle-Shaped Red Blood Corpuscles in a Case of Severe Anemia."

However, the name, sickle cell anemia, was not coined until in 1922, by Vernon Mason. It was also the first diagnosed genetic disease and the first to be linked to the hemoglobin protein.

But, how did it gain the name "Black Disease"? This is because the disease often disproportionately affected Black Americans in the US, which caused racial bias and prevented people with sickle cell from receiving quality care.

In response to this, in the 1960s, the Black Panther Party worked to expand community-based care for education and treatment of this disease. This was part of their initiative to tackle the sickle cell, which received little to no attention because it mostly affected a large part of Black community.

While Herrick may have described the first known case in the US, SCD did exist for generations in African and Mediterranean descent, due to the regions being prone to diseases like malaria. In African medical literature, it was known as "ogbanjes", which loosely translated into "children who come and go" as the infants born with this disease had a high mortality rates. One of the first records, as is also noted by the Sickle Cell Association from Africa is from a Ghanian family in 1670.

A Groundbreaking Discovery

In 1927, scientists Hahn and Gillespie made a discovery that reshaped our understanding of blood disorders. While studying red blood cells in a low-oxygen environment saturated with carbon dioxide, they observed a curious phenomenon: the cells twisted into sickle shapes—not just in patients with sickle cell disease (SCD), but sometimes in people without any symptoms at all.

This puzzling observation hinted at an invisible carrier state and eventually led to the identification of what we now call the sickle cell trait.

Fast-forward to the late 1940s and early 1950s, and the pieces of the puzzle began falling into place. In 1949, two scientists working continents apart independently uncovered the genetic blueprint of SCD.

Col. E. A. Beet, a military physician stationed in what is now Mozambique, published his findings in an African medical journal. Around the same time, Dr. James V. Neel at the University of Michigan released a parallel study in the journal Science. Both revealed that SCD follows an autosomal recessive inheritance pattern—meaning the disease only occurs when a person inherits two copies of the mutated gene. Those with just one copy? They carried the trait, but not the illness.

Together, their work laid the foundation for our modern understanding of genetic inheritance and reshaped how we screen for and manage sickle cell disorders today.

Roughly one out of six people globally suffer with infertility according to the World Health Organization. A common issue that affects many, infertility, is a condition where a person is unable to reproduce offsprings. While the condition may be common, it can cause a lot of health problems as well as stress for people who wish to have children. To tackle this, people often opt for fertility treatment including reproductive technology called in vitro fertilization (IVF). However, could your infertility be a sign of impending health issues?

A new evidence review suggests a link between infertility in women and a heightened risk of heart problems, particularly among younger women and those undergoing fertility treatments.

Is Infertility An Early Warning for Heart Health?

Infertility may serve as an early sign for future heart health issues, according to researchers at the National and Kapodistrian University of Athens in Greece. This finding was recently presented in Copenhagen, Denmark, at a joint meeting of the European Society of Pediatric Endocrinology and the European Society of Endocrinology.

Researchers looked at data from many different studies – almost 21 of them! They compared nearly 179,000 women who couldn't get pregnant with about 3.4 million women who didn't have fertility issues. What they discovered was that women who were infertile had a higher chance of facing heart issues:

• They were 17% more likely to get heart disease, which is a general term for problems with the heart itself.
• They had a 16% higher chance of having a stroke, which happens when blood flow to the brain is blocked.
• They were 14% more likely to have problems with their heart or blood vessels in general.

Elevated Risk for Younger Women and Those Undergoing Treatment

The research highlights two groups of women who face an even bigger risk. First, it's younger women. The study found that women under 40 who were infertile had a 20% higher chance of heart disease. That's a significant increase for younger individuals. Second, it also showed that women who went through fertility treatments (like IVF) had an 18% greater risk of heart problems. This suggests that either the treatments themselves or the underlying reasons for needing them could be connected to heart health.

Implications for Clinical Care

Researchers believe that because infertility might be an early sign of heart problems, doctors can use this information. They can identify women who might need extra check-ups or special strategies to prevent heart disease earlier in life. It's like giving doctors a heads-up to be more careful with these patients. She also brought up an important question: what are the long-term effects of fertility treatments on a woman's heart? This is something doctors need to consider.

Researchers want to follow women’s health over time to really understand why infertility might be linked to heart health. They hope to figure out the exact biological reasons behind this connection and identify which specific groups of women are most at risk. The ultimate goal is to use all this information to create better guidelines for preventing heart disease early on and to improve heart care for women who have had infertility.
