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.

Cardiovascular-kidney-metabolic (CKM) syndrome is emerging as a major public health threat, according to new guidelines from the American Heart Association (AHA), which identify obesity as a key driver of the condition's development and progression.

The guidelines, jointly issued by the AHA and the American College of Cardiology (ACC), reframe excess weight as more than a number on the scale, describing it as a significant health risk closely linked to diabetes, chronic kidney disease and cardiovascular disease.

According to the AHA, nearly 9 in 10 adults in the United States have at least one condition associated with CKM syndrome. These include high blood pressure, abnormal cholesterol and other lipid disorders, high blood sugar, reduced kidney function and excess body weight.

With obesity rates continuing to rise, the guideline urges healthcare professionals to have prevention-focused conversations with patients about maintaining a healthy weight to reduce the risk of future heart, kidney and metabolic diseases.

“CKM syndrome is a real, rising public health threat,” said Chiadi E. Ndumele, an American Heart Association volunteer and chair of the writing committee for the new guideline.

“In terms of CKM health, weight is not just about a number on a scale — people with the same body weight can have very different health profiles. Rather, what’s most important is how fat tissue affects your metabolic health. This includes how your body manages blood sugar levels and how fat is used and stored,” Ndumele, who is also director of obesity and cardiometabolic research at Johns Hopkins University in Baltimore.

The updated guideline replaces the 2013 recommendations for managing overweight and obesity. CKM syndrome itself was first formally defined by the American Heart Association in 2023.

The guideline highlights several strategies to improve the prevention and treatment of CKM syndrome:

• Use the Predicting Risk of Cardiovascular Disease EVENTs (PREVENT) equations to estimate 10-year and 30-year cardiovascular disease risk. Unlike previous tools, PREVENT incorporates kidney and metabolic health factors for a more comprehensive risk assessment.
• Screen patients for social determinants of health, including food insecurity, housing instability and financial strain, which can increase the risk of CKM syndrome.
• Promote coordinated, multidisciplinary care focused on healthy lifestyle behaviors, including physical activity, nutrition, weight management, blood pressure control, blood sugar management and cholesterol reduction.
• Alongside lifestyle interventions, use medications and surgical therapies when appropriate to manage blood pressure, cholesterol, blood sugar and obesity while protecting heart and kidney health.
• For the first time, the guideline recommends GLP-1-based therapies for select individuals with obesity and/or Type 2 diabetes who are at elevated cardiovascular risk. Metabolic and bariatric surgery is also recognised as an effective treatment option for eligible patients.

The guideline emphasizes that early lifestyle changes can significantly reduce the risk of heart attack, heart failure, stroke and kidney failure.

People are encouraged to follow the AHA's Life's Essential 8, which promotes

• regular physical activity,
• a heart-healthy diet,
• maintaining a healthy weight,
• controlling blood pressure,
• maintaining blood sugar
• better cholesterol control,
• avoiding tobacco,
• getting sufficient quality sleep.

The monsoon brings welcome relief from the heat, but it also creates conditions that make infections spread more easily among children. Parents should understand that a few common household mistakes can increase the risk of illness in children during this time of year. So, parents must exercise caution and take utmost care of their children during those rainy days.

Why Monsoon Raises Infection Risk in Children

The arrival of the monsoon often means more time spent indoors for children, muddier surroundings, and increased exposure to germs. So, the main focus of parents is on protecting their children from rain and cold weather. However, parents must understand that certain everyday habits at home may unknowingly increase the risk of respiratory infections, stomach illnesses, and mosquito-borne diseases.

Common Mistakes Of Infections In Children

So, many children can get drenched during those heavy rains and remain in wet clothes or footwear for long periods after returning from school or outdoor activities. Damp socks and shoes can create an environment where germs and fungal infections thrive. Parents should ensure that children change into dry clothes and footwear as soon as possible. Moreover, stagnant water collected in flower pots, buckets, coolers, balconies, and outdoor containers can become breeding grounds for mosquitoes, raising the chances of dengue, malaria, and chikungunya in children.

Many families keep doors and windows closed throughout the day to prevent rainwater from entering the house. However, limited air circulation can lead to the growth of mold, dampness, and indoor allergens, which may trigger respiratory infections, coughing, wheezing, and allergies in children. Even having uncovered food, improperly stored leftovers, or contaminated water can increase the risk of stomach infections, diarrhea, vomiting, and food poisoning in children.

Tips Parents Should Follow During the Monsoon

Parents should ensure that the child changes wet clothes, socks, and shoes immediately after returning home. Parents should empty and clean containers that can collect stagnant water from time to time. Use mosquito nets, screens, and child-safe mosquito repellents to prevent mosquito bites. Keep rooms well ventilated whenever the weather permits. The child should follow good hand and personal hygiene, eat freshly cooked food, and drink safe drinking water.

The parents should ensure to wash fruits and vegetables thoroughly before consumption. The child should eat a nutritious diet, sleep well, and stay hydrated to boost immunity and prevent any illness. Parents should seek immediate help if the child is having any symptoms, such as a cough or allergies, and follow the expert's guidelines. Parents should not give any medication to the child on their own without the doctor's knowledge. So, parents should stay alert during the monsoon and help the child stay healthy.

Billionaire entrepreneur Bryan Johnson, known for meticulously tracking his health and pursuing longevity, recently revealed that he has been diagnosed with Autoimmune Gastritis, an incurable autoimmune condition in which the body's immune system attacks the stomach lining.

Describing the disease on social media platform X, Johnson said: "My stomach is eating itself." He also noted that despite undergoing extensive medical evaluations over the years, the condition went undetected because autoimmune diseases often develop quietly, with symptoms that can easily be mistaken for everyday health issues such as fatigue or digestive discomfort.

According to the Centers for Disease Control and Prevention (CDC), autoimmune diseases occur when the immune system mistakenly attacks the body's own healthy cells and tissues, triggering inflammation and damage to organs or other body systems.

The burden of these conditions is significant. In May 2025, researchers from the Mayo Clinic and collaborating institutions estimated that nearly 15 million Americans are living with one or more of 105 recognized autoimmune diseases.

Symptoms Can Be Easy to Miss

Because autoimmune diseases often begin with vague, non-specific symptoms, they can remain undiagnosed for months—or even years.

Dr. Cory Rice, a US-based Functional Medicine physician, said these warning signs frequently go unnoticed until the disease has progressed.

"First and foremost, symptoms of autoimmune disease can come and go, and be on and off, or they can be more persistent in nature," he told Newsweek.

The Hidden Signs You Shouldn't Ignore

While symptoms vary depending on the various autoimmune conditions, several early warning signs are shared across many autoimmune diseases.

According to Dr. Rice, common symptoms include:

• Fatigue
• Low-grade fever
• Joint pain
• Unexplained rashes or hives
• Dry eyes and dry mouth
• Numbness or tingling in the hands or feet
• Mouth ulcers
• Increased sensitivity to cold temperatures

He said when people suffer from fatigue, "it is usually both profound and debilitating."

Dr. Rice explained that many people try to manage this overwhelming exhaustion by relying on caffeine and other stimulants, taking thyroid medications or hormone treatments, or opting for therapies such as intravenous infusions and vitamin B12 injections.

However, when an underlying autoimmune disease is responsible, these approaches often fail to provide lasting relief.

Why Autoimmune Diseases Are Often Diagnosed Late

One of the biggest challenges in diagnosing autoimmune diseases is that their symptoms overlap with those of many other medical conditions.

Johnson also said that "2-5 per cent of people have this (autoimmune disease). Likely more, because it hides".

Symptoms may also appear intermittently before becoming more persistent.

"It all depends on the disease process in play and the severity or progression of the disease itself in a particular person as to whether symptoms are more constant or intermittent," Rice said.

He added that many primary care physicians are not routinely trained to identify autoimmune diseases in their early stages. As a result, patients are frequently referred to specialists, including rheumatologists, only after symptoms have become more pronounced.

"Unfortunately, by this point, the autoimmune disease may already be far along in whichever parts of the body are impacted," he said.

Dr. Rice emphasized that recognizing symptoms early and obtaining a timely diagnosis can help slow disease progression and improve long-term outcomes.
