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.

A study of more than 700 individuals found distinct differences in the mix of bacteria in the mouths and lungs of those with severe long COVID.

Published in the European Respiratory Journal, the study found that differences in the lung microbiome were linked to respiratory problems, cognitive difficulties and digestive symptoms associated with long COVID.

The findings may help researchers understand why some people develop long COVID and identify potential treatments, according to the team from the University of Dundee, UK.

"The microbiome is important to maintain health throughout the body, so it is a strong candidate for something that may contribute to long COVID,” said lead author Dr. Daniela Alferes de Lima Headley.

The observational study included 771 adults who had been hospitalized for COVID-19 between February 2020 and March 2021. Researchers grouped participants according to the severity of their ongoing health problems and symptoms.

The participants had an average age of 57.5 years, and 38.5% were women.

Six months after hospital discharge, researchers collected saliva samples to examine microbes in the mouth and sputum samples to study the lung microbiome. They used DNA sequencing to identify the microbes and analyze their diversity. Participants also completed questionnaires about their symptoms.

The results showed that people with very severe long COVID had distinct differences in their oral and lung microbiomes compared with those who had fewer ongoing symptoms.

Microbiome differences were also associated with:

• • Respiratory problems: Reduced lung function.
  • Cognitive symptoms: Brain fog, memory problems, and difficulty with attention and concentration.
  • Digestive issues: Abdominal pain, nausea, diarrhea and loss of appetite.

Bacterial Changes Linked To Inflammation

Further, the changes associated with long COVID symptoms also included an increased abundance of bacteria that produce lactic acid. These changes were also linked to signs of inflammation in participants' blood samples.

James Chalmers, chair of respiratory research at the University of Dundee, said the greatest microbiome changes were found in people with the most severe symptoms five to six months after COVID-19.

"We also found that changes in the airway microbiome were linked not just to lung problems, but also to symptoms like brain fog and gut symptoms, suggesting the lung microbiome could have effects on health more broadly," he added.

However, the researchers do not yet know whether these microbiome differences existed before COVID-19 or developed after infection. The long-term effects of these changes also remain unknown.

Could The Findings Lead To New Treatments?

Chalmers said more research is needed to understand what causes long COVID, which continues to affect many people worldwide.

Because the microbiome can be altered through interventions such as antibiotics and probiotics, understanding its role could help researchers explore potential treatment options.

What Is Long COVID?

Long COVID refers to new, returning or ongoing health problems that persist four or more weeks after the initial COVID-19 infection. Symptoms can last for months or even years.

Common symptoms include fatigue, brain fog, memory problems, difficulty concentrating and slowed thinking.

Research has also suggested that brain inflammation may persist even after the virus is no longer detectable.

For some women with endometriosis, getting a diagnosis is only the beginning of a long struggle to access treatment and navigate management.

In Canada, long waitlists for specialist appointments are pushing patients to consider expensive surgery abroad, highlighting how delays in care can prolong pain and disrupt everyday life.

Noelle Menu, 37, from Calgary, said her symptoms intensified after she stopped taking birth control while trying to conceive at 26.

Years of pain, emergency room visits, surgery and delays in specialist care eventually led her and her husband to seek private treatment in Tijuana, Mexico.

After being told that waiting several years to see a specialist in Canada was possible, Menu said: “We can’t deal with it in Canada.”

The couple used their savings and went into debt to pay for treatment at EndoGlobal in Mexico. The total cost was approximately $35,000, including travel, accommodation and other expenses, according to CBC News.

Her experience highlights the delay in addressing endometriosis that can intensify debilitating symptoms.

What Is Endometriosis And Why Can It Be Difficult To Diagnose?

Endometriosis is a chronic condition in which tissue similar to the lining of the uterus grows outside it, potentially affecting the ovaries, bowel, bladder and other areas. The resulting inflammation and scar tissue can cause severe menstrual cramps, persistent pelvic pain, painful sex, bowel or urinary symptoms and difficulties conceiving.

The World Health Organization estimates that endometriosis affects around 10% of reproductive-age women worldwide, or approximately 190 million people.

Diagnosis can be challenging because symptoms vary and may overlap with other conditions. There is no single definitive test that identifies every case. Doctors may use a detailed medical history, pelvic examination, ultrasound or MRI, with surgery sometimes needed to investigate or treat suspected disease.

The WHO estimates that diagnosis commonly takes between four and 12 years, leaving many patients managing symptoms without a clear explanation for prolonged periods.

How Do Delays Affect Patients?

For patients with severe disease, waiting for specialist care can mean continuing to live with pain that interferes with work, relationships, sleep and fertility plans.

Another Canadian patient, identified in CBC's report as Papiernik, described discovering that endometriosis had infiltrated her colon after a colonoscopy detected a mass. She was referred for specialist care but faced further waits for an appointment and surgery.

“Living like this for two years was just not an option for me,” she said.

Canada's House of Commons health committee has identified gaps in endometriosis care, while the condition's economic impact includes lost productivity and healthcare costs. The issue is not simply whether treatment exists, but whether patients can access appropriate care before symptoms and complications become harder to manage.

Does Surgery Cure Endometriosis?

Surgery can remove endometriosis lesions, adhesions and scar tissue, reducing pain and treating complications. However, it is not a guaranteed cure. Symptoms may persist or return, and treatment decisions depend on disease severity, the organs involved, fertility goals and previous treatment.

Hormonal medicines and pain management can also help control symptoms. Some patients benefit from a combination of medical treatment, surgery and ongoing follow-up.

Travelling abroad may offer faster access to specialist treatment, but it comes with financial costs and other challenges. Patients should consider the surgeon's experience, the facility's standards, the possibility of complications and arrangements for follow-up after returning home.

A routine heart scan helped doctors detect pancreatic cancer in a 72-year-old US woman before it was too late. Vicky Titcomb, a Cape Cod bookstore owner and great-grandmother, underwent the scan at Mass General Brigham in March 2025, before traveling to New York City to visit her son.

Although she felt healthy, the scan revealed an abnormality on her pancreas. Further testing confirmed pancreatic cancer, one of the deadliest forms of cancer, CBS News reported.

“I felt like my life just switched in that moment,” Titcomb said. “It was a very weird feeling.”

Titcomb had undergone treatment for breast cancer in 2012.

In 2025, she was diagnosed with stage 1 breast cancer as well as pancreatic cancer. Doctors also found a mass on her ovary, which proved benign after the ovary was removed.

Why Early Detection Matters In Pancreatic Cancer

Pancreatic cancer is often diagnosed after it has spread to other organs. Its five-year overall survival rate is 13%.

The American Association for Cancer Research noted in its 2026 Cancer Progress Report that pancreatic cancer survival rates have shown little improvement despite advances in cancer care.

Doctors at Mass General Brigham planned chemotherapy and radiation to shrink Titcomb’s pancreatic tumor before surgery.

“I was told the size of the (pancreatic) cancer was about the size of a grape. The goal, to me, was trying to make this cancer a raisin,” she said. “That's the way I visualized it.”

The plan was to perform a Whipple procedure, a complex operation that removes the head of the pancreas, part of the small intestine, the gallbladder and the bile duct. Only about one in five pancreatic cancer patients is eligible for this surgery.

Titcomb’s early diagnosis made the operation possible.

“If I had not had that scan when I did, the outcome would have been bad,” she said.

Titcomb began chemotherapy in June 2025, receiving eight doses over four months. She then underwent three weeks of radiation and additional chemotherapy.

Surgical oncologist Dr. Thomas Clancy said she tolerated the treatment “very well.” The therapy shrank the pancreatic tumor enough for surgery.

On November 4, Titcomb underwent surgery to treat her breast cancer. Just over two weeks later, Clancy performed a robotic Whipple procedure to remove the affected part of her pancreas and other structures.

The operation was successful, and Titcomb said she was walking that night. She returned home after several days in the hospital.

Although she was recovering well, Clancy recommended two more months of chemotherapy because pancreatic cancer can be aggressive.

“There was a lot going on,” Titcomb said. “I just tried to cope with the day-to-day.”

No Evidence Of Cancer After Treatment

In March 2026, after further treatment, Clancy told Titcomb she had no evidence of cancer. She will continue to undergo scans every three months.

“She’s living her life. I generally tell patients at this point, ‘You’re done with therapy ... you go about your days,’” Clancy said. “The goal is to not be thinking about it all the time.”

Titcomb is returning to running her bookstore, which family members helped manage during her treatment. She is also spending time with her children, grandchildren and great-grandchildren, keeping in touch with those who live far away through photos, videos and phone calls.
