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.

Indian Actress Dipika Kakkar, battling liver cancer, underwent another surgery last month for a 1.3 cm cyst that reappeared.

Best known for her role as Simar Bhardwaj in the hit TV show Sasural Simar Ka, Dipika underwent a major tumour-removal surgery in June 2025. She also undertook chemotherapy

In her latest vlog, Dipika shared that the unexpected recurrence has left her feeling anxious and overwhelmed as doctors evaluate the next course of treatment.

"The recurrence that happened with the 1.3 cm cyst has shaken me. I am a little scared now that it shouldn't happen again. I have started dieting, but I feel anxious," she said.

HealthandMe spoke to health experts to understand why cysts recur in liver cancer patients and how it's important to keep monitoring them.

According to health experts, a biannual liver scan is imperative, and it can detect signs of cysts.

“Simple cysts less than 2-3 Cm can be observed with repeat scans every 6 months to 1 year. Suspicious or malignant cysts need surgical resection and oncological treatment based on the histopathology and patient condition,” Dr Manjunath NML, Sr Consultant, Surgical Oncology and Robotic Surgeon, HCG Cancer Hospital, K R Road, Bengaluru.

What Are Liver Cysts? How It's Linked To Cancer

Liver cysts are like bags that are filled with fluid. They are usually not cancer. Most people who have liver cysts do not get cancer.

However, just because one has a cyst, it does not mean it's cancer.

“Cysts in the liver are typically harmless and unrelated to liver cancer. However, unusual types of cysts may suggest malignant changes that need further examination, particularly among risk groups,” Dr. Govind Nandakumar, Consultant – Gastrointestinal Surgery, Manipal Hospitals Hebbal, told HealthandMe.

The experts noted that cases of recurring cysts related to liver cancer are uncommon. But they occur because of

• the presence of cancerous cells,
• regrowth of the organ,
• chronic conditions like cirrhosis.

Are There Early Warning Signs Patients Should Watch For?

Many liver cysts do not cause any problems in the early stages. That is why regular check-ups with a doctor are important. If a cyst grows or becomes problematic, symptoms may begin to appear. These can include

• abdominal pain,
• bloating,
• nausea,
• weight loss,
• yellowing of the skin,
• fatigue.

Is Recurrent Cysts A Cause Of Worry?

Recurrent cysts can be effectively managed and treated over time. The recurrence does not necessarily imply the progression of the condition itself; however, more tests may be required to determine whether cysts are malignant or benign.

“Cysts with thick walls, septations inside, and solid components in them are more likely to be cancerous. If the cysts are large, they cause symptoms like pain, distension, and obstruction of the bowel or biliary tract,” Dr Manjunath said.

The experts explained that diagnosis can be achieved by scans like ultrasonography, Computerized Tomography CT or Magnetic Resonance Imaging (MRI). Suspicious cysts must be checked via biopsy to confirm malignancy.

While suspicious or malignant cysts require surgical resection and oncological treatment, symptomatic cysts, even if benign, may also require removal.

However, if a liver cyst is detected without suspicious features and is asymptomatic, it usually does not require any intervention, Dr. Manjunath noted.

What if the body whispers long before it screams? For many living with Parkinson’s disease, the earliest signs are not the tremors, but quieter changes, such as a diminished sense of smell, disrupted sleep, or gut problems. The challenge is that we are conditioned to look for the disease only once it becomes visible.

Parkinson’s disease, commonly referred to as a movement disorder, progresses slowly due to the destruction of the nerve cells in the brain.

To understand Parkinson’s disease, think of the brain as a command center where certain nerve cells produce dopamine, a chemical messenger that helps coordinate smooth movement. As these dopamine-producing cells gradually deteriorate, the brain’s signalling system gets disturbed, leading to slower movements, mistaken for normal ageing.

The majority of patients experience subtle early signs much before diagnosis, including a reduced sense of smell, sleep disturbances like insomnia, and persistent digestive problems like constipation. In these cases, timely intervention can reduce movement disability by roughly 40 percent.

Conventional treatment focuses on medications that boost dopamine levels, but over time, their effectiveness may decline. When drugs are no longer sufficient, doctors may recommend Deep Brain Stimulation (DBS), a surgical approach that works like a pacemaker for the brain and uses chest-connected electrodes to reset faulty signals causing stiffness and tremors.

Unlike fixed traditional stimulation, the advanced Adaptive DBS (aDBS) listens to brain signals in real-time to adjust therapy automatically. Its single threshold mode reacts instantly, boosting stimulation the moment brain signals hit a specific limit and turns it off just as fast once they improve.

Alternatively, its double threshold mode keeps stimulation steady within the safe zone," making only gradual tweaks if signals cross upper or lower limits. This smart system mimics the body’s natural rhythm to provide fluid symptom control while preventing overstimulation, ultimately helping you reclaim more "good" time and independence.

Parkinson’s Diet

There is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.

Plant-based flavonoids, present in berries, citrus fruits, and broccoli, which have antioxidant effects, can help protect brain cells from damage. Drinking enough water can support digestion and prevent dehydration.

Ultimately, small, consistent dietary choices, combined with medical guidance, can make a meaningful difference in managing symptoms.

Parkinson’s disease is a journey, and the earlier the signs are recognized, the better the condition can be managed. If you or a loved one is experiencing persistent changes in sleep, smell, or movement, do not wait for the symptoms to become overwhelming. Consulting a neurologist is the first step toward taking back control of your health.

While salt, cholesterol, and obesity are major factors driving high blood pressure, a recent study suggests they may not be the only causes.

Researchers from Brazil and New Zealand have identified a brain region that may increase the risk of hypertension. The study, published in the journal Circulation Research, showed that the brain region called the lateral parafacial region is the culprit.

The lateral parafacial region sits in the brainstem – the oldest part of the brain – which controls automatic functions such as digestion, breathing, and heart rate.

“The lateral parafacial region is recruited into action, causing us to exhale during a laugh, exercise, or coughing,” said lead researcher Professor Julian Paton, from the Centre for Heart Research at Waipapa Taumata Rau, University of Auckland.

“These exhalations are what we call ‘forced’ and are driven by our powerful abdominal muscles. In contrast, a normal exhalation does not need these muscles to contract; it happens because the lungs are elastic,” Paton added.

Can Breathing Patterns Signal Hypertension?

Paton and the team found that the lateral parafacial region also connects to nerves that tighten blood vessels -- a mechanism that raises blood pressure.

“We’ve unearthed a new region of the brain that is causing high blood pressure. Yes, the brain is to blame for hypertension!” Paton said.

“We discovered that, in conditions of high blood pressure, the lateral parafacial region is activated and, when our team inactivated this region, blood pressure fell to normal levels.”

The team explained that this means changes in breathing patterns – especially those involving strong abdominal muscle contractions – can trigger high blood pressure. Thus, any diagnosis of abdominal breathing in patients with high blood pressure may reveal the cause and hence direct appropriate treatment.

Can The Brain Region Help Treat Hypertension

The next question was whether the brainstem region could be treated with a medication.

“Targeting the brain with drugs is tricky because they act on the entire brain and not a selected region such as the parafacial nucleus,” Paton said.

The researchers then discovered that this region is activated by signals from outside the brain – from the carotid bodies, tiny clusters of cells in the neck near the carotid artery that sense oxygen levels in the blood.

These can be targeted safely with medication, they said.

“Our goal is to target the carotid bodies, and we are importing a new drug that is being repurposed by us to quench carotid body activity and inactivate ‘remotely’ the lateral parafacial region safely, i.e., without needing to use a drug that penetrates the brain.”

This finding could lead to new treatments for high blood pressure, especially for people who also have sleep apnea, as we know carotid bodies are activated in these patients when they stop breathing at night.

Global Burden Of Hypertension

Hypertension is commonly referred to as the "silent killer" due to its lack of noticeable symptoms. Unchecked, it progressively damages your arteries and vital organs.

It occurs when the pressure in your blood vessels is consistently higher than normal—usually 140/90 mmHg or more, states the World Health Organization (WHO). The normal and healthy level is estimated to be 120/80 mmHg. Blood pressure increases when the arteries get narrow or stiff, causing the heart to work harder.

At a global level, an estimated 1.28 billion adults aged 30 to 79 years have hypertension, and most of them live in low- and middle-income nations. Alarmingly, 46 percent of them do not even know they have it, and just 1 in 5 keeps it under control, as per WHO statistics.

In the US alone, the Centers for Disease Control and Prevention (CDC) estimates that nearly 47 percent of adults, or roughly 116 million individuals, have hypertension, yet only 24 percent control it well. The economic burden is just as overwhelming, with the US spending $131 billion each year on care related to hypertension.

Exercise, lifestyle changes, and diet are key to preventing hypertension
