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.

More than 10 million adults, young people, and children in the UK are currently living with arthritis, according to a 2025 report by Arthritis UK. The NHS states that osteoarthritis is the most common form of the condition nationwide.

As per Cleveland Clinic, osteoarthritis develops gradually as joints become stiff and painful due to wear and tear. Symptoms can vary depending on the joint affected and the extent of damage, but pain, swelling, and reduced movement are common. While medication is often prescribed to manage symptoms, the NHS cautions that some commonly used treatments can carry health risks if taken long-term or without proper guidance.

One of the most frequently used pain relief options is non-steroidal anti-inflammatory drugs, commonly known as NSAIDs.

What Are NSAIDs?

NSAIDs, or non-steroidal anti-inflammatory drugs, are commonly prescribed by GPs to help relieve pain, swelling, and inflammation. They are available in several forms, including tablets, capsules, suppositories, creams, gels, and injections. Some NSAIDs can be purchased over the counter, while stronger versions require a prescription.

These medicines are often relied upon for day-to-day pain relief by people with osteoarthritis, particularly during flare-ups.

NHS Warning: Who Should Be Cautious When Using NSAIDs?

The NHS advises that NSAIDs may not be suitable for everyone. Extra caution is recommended for people with asthma, a history of stomach ulcers, angina, or those who have previously experienced a heart attack or stroke. The NHS also advises that individuals taking low-dose aspirin should always consult their GP before using NSAIDs.

Long-term or incorrect use can increase the risk of stomach bleeding, cardiovascular problems, and kidney issues, making it important to review pain management plans regularly.

Can Natural Compounds Like GOPO Support Joint Health?

Consultant Rheumatologist Dr Rod Hughes explains that natural compounds are increasingly being explored as supportive options for joint health.

“Natural compounds derived from plants have long been used in both traditional and modern medicine to support joint health. One such compound is GOPO, which is derived from rose hips (Rosa canina). Research indicates that GOPO can help relieve joint pain due to its anti-inflammatory properties,” he says.

“Rather than simply masking symptoms, GOPO works by helping to regulate the body’s inflammatory response, which is a key driver of joint stiffness, swelling, and discomfort. It offers a promising alternative to traditional painkillers, with fewer risks of side effects, making it a more sustainable option for managing joint discomfort.”

Lifestyle Changes Proven To Ease Osteoarthritis Pain

According to Dr Hughes, lifestyle measures form the foundation of osteoarthritis management.

“Lifestyle choices play a central role in relieving osteoarthritis pain and helping people stay active,” he explains. “Research shows that regular, gentle exercise supported by physiotherapy, such as walking, swimming, and yoga, can be highly effective.”

“These activities help keep joints mobile and strengthen the muscles and ligaments that support them, which reduces stiffness and eases pressure on painful joints. It is also important to balance activity with rest to avoid flare-ups caused by overuse.”

Why Weight Management Matters For Joint Health

Weight management is another key factor in controlling osteoarthritis symptoms. “Maintaining a healthy body weight is especially important,” says Dr Hughes. “Extra weight places additional load on joints, particularly the knees and hips, which can worsen pain and accelerate joint damage. Even modest weight loss has been shown to significantly reduce pain and improve mobility.”

How Diet Influences Inflammation And Joint Pain

Interestingly, diet can also play a role in managing inflammation linked to osteoarthritis. “Eating plenty of fresh fruit and vegetables, whole grains, nuts, and seeds, along with at least two portions of oily fish each week, provides antioxidants and omega-3 fatty acids that help reduce inflammation and protect against cell damage,” Dr Hughes explains.

“In my practice, I often recommend combining these dietary changes with natural supplements such as turmeric or GOPO to provide additional support for joint health.”

Reducing Reliance On Long-Term NSAIDs Safely

For patients hoping to reduce their dependence on NSAIDs, Dr Hughes stresses the importance of medical supervision.

“Any reduction in NSAIDs should be done gradually and under the guidance of a healthcare professional. This helps ensure pain remains well controlled while avoiding sudden flare-ups or withdrawal issues,” he says.

“By combining regular movement, physiotherapy, supportive nutrition, and appropriate natural supplements, many patients can take a more balanced approach to managing chronic joint pain. Over time, these strategies may allow people to rely less on medication while maintaining a good quality of life.”

A doctor has cautioned that certain people may need to cut back on their favourite fruits if they are taking specific heart or blood pressure medicines. Ignoring this advice could lead to a serious but preventable health issue. Speaking during a past appearance on ITV’s This Morning, as reported by the Mirror, GP Dr Chris Steele explained that some prescribed drugs can react poorly with everyday foods. Eating these foods in large amounts may interfere with how the medication works and, in some cases, cause dangerous side effects.

He drew attention to two common fruits that many households keep on hand. The doctor warned that anyone taking medicines known as ACE inhibitors should avoid bananas and oranges. During the interview, he said: “Bananas are high in potassium, which is not suitable for certain medications. People taking ACE inhibitors such as captopril, enalapril, fosinopril, and others should try not to eat bananas or oranges.”

ACE inhibitors are used to lower blood pressure and treat heart failure by relaxing and widening blood vessels, allowing blood to circulate more easily. They are often prescribed as a first-line treatment for high blood pressure, heart failure, and some kidney conditions, though regular monitoring is needed to watch for possible side effects.

What Causes High Blood Pressure?

High blood pressure, also known as hypertension, occurs when blood pushes too forcefully against artery walls. Over time, this can damage blood vessels as well as vital organs such as the heart, brain, and kidneys. The condition often has no obvious symptoms, but it can increase the risk of heart attacks, strokes, kidney failure, vision problems, and aneurysms. Constant pressure makes the heart work harder, which may eventually lead to heart failure or thickening of the heart muscle, according to the Mayo Clinic.

Hypertension is usually linked to lifestyle factors like a high-salt diet, excess weight, lack of physical activity, and smoking. Age, genetics, and underlying health problems such as kidney disease also play a role. The condition develops when pressure inside the arteries rises, sometimes due to stress, hormonal changes, or long-term poor eating habits.

Why Are Blood Pressure Patients Being Advised To Avoid These Fruits?

Bananas, along with oranges and some salt substitutes, contain high levels of potassium. When combined with ACE inhibitors, these foods can cause potassium levels in the blood to rise too much. Mild increases may lead to symptoms such as stomach pain, diarrhoea, nausea, or vomiting. However, many people do not notice any symptoms until potassium levels become dangerously high, which can increase the risk of chest pain, heart palpitations, and an irregular, rapid, or fluttering heartbeat.

Patients are advised to inform their GP if they are taking potassium supplements or diuretics alongside blood pressure medication. Those on ACE inhibitors should avoid eating large quantities of foods that are high in potassium.

The NHS advises people in the UK to aim for five portions of fruit and vegetables each day. Since all fruits contain some potassium, no option is completely risk-free when eaten in excess. That said, some fruits are much lower in potassium than bananas and oranges. These include apples, berries, grapes, pineapples, and pears.

Watermelon is generally classed as low to moderate in potassium, making it a suitable choice for people following a low-potassium diet. One standard serving of diced watermelon contains roughly 170 to 180 mg of potassium, which is far lower than levels found in fruits like cantaloupe.

According to the NHS, adults aged 19 to 64 need about 3,500 mg of potassium each day, which can usually be met through a balanced diet. A doctor can help address individual concerns and offer guidance based on personal health needs.

Heart stents have saved countless lives and remain one of the most effective treatments for blocked coronary arteries. By improving blood flow to the heart, they help relieve chest pain and lower the risk of serious events such as heart attacks. Today, stent placement is a routine, minimally invasive procedure performed on millions of patients each year. Yet as more people live longer with stents, an important question is gaining attention: how well do these devices hold up over time inside a constantly moving, living artery?

Stents are widely used to treat blocked or narrowed arteries, particularly in people with severe or advanced coronary artery disease. By restoring blood flow, they help ease chest pain, known as angina, which occurs when the heart muscle does not receive enough oxygen and nutrients because of reduced circulation.

Each year, millions of patients undergo stent procedures, making it one of the most commonly performed minimally invasive treatments worldwide. While stents have transformed heart care, it is still important to understand their limitations, especially as newer and more advanced technologies continue to emerge.

Why Are Stents Placed In Blocked Heart Arteries?

Before looking at how stents behave over time, it helps to understand the environment in which they are placed. We got in touch with Dr. Tamil Selvan Muthusamy, Primary Investigator in the MY-IVL Study of Elixir Medical’s Device and Consultant Cardiologist at Cardiac Vascular Sentral Kuala Lumpur (CVSKL), who told us, that coronary arteries, which supply blood to the heart, are living, flexible structures. They bend, twist, stretch, and move constantly with every heartbeat to manage changing blood flow and pressure.

These arteries travel along the surface of the heart, wrapping around its curves from base to tip, delivering oxygen-rich blood to every heart muscle cell. As the heart contracts and relaxes, the arteries shift side to side, stretch lengthwise, and twist repeatedly. Blood flow within them also changes throughout the heartbeat, moving more slowly during contraction and faster during relaxation. This constant motion creates friction and stress along the artery lining, known as the endothelium.

Under healthy conditions, this stress helps maintain vessel function. However, when blood flow is disrupted, small areas of damage can occur, allowing plaques to form, harden, and eventually block the artery.

A stent is a tiny metal mesh tube mounted on a deflated balloon catheter and guided through the arteries to the site of blockage. Once the balloon is inflated, the stent expands, pushing the plaque aside. The balloon is then removed, leaving the stent in place to keep the artery open, much like internal scaffolding.

Why Does Heart Stent Performance Decline Over Time?

Over the past two decades, research has shown that stents can behave like rigid cages inside arteries. Dr Selvan Muthusamy told us that depending on their length and position, they may restrict the artery’s natural ability to bend, twist, stretch, and pulse with each heartbeat. This stiffness can damage the delicate inner lining of the artery and increase stress on the vessel wall by limiting its natural movement.

When these mechanical changes alter normal blood flow patterns, they can trigger inflammation or excessive tissue growth inside the stent. This process, known as restenosis, is one of the main reasons stents fail over time. Long-term studies suggest that stents have an annual failure rate of around 2 to 3 percent. For patients, this may show up as the return of chest pain and, in some cases, can lead to a heart attack.

As explained by Dr Selvan Muthusamy, the challenge lies in matching rigid implants with arteries that are meant to move continuously. When this balance is disrupted, long-term complications become more likely.

Can Lifestyle Changes Help Prevent Stent-Related Complications?

Healthy habits play a major role in protecting stents and overall heart health. Patients are advised to stop smoking, follow a heart-friendly diet low in salt and unhealthy fats, and stay physically active, such as walking for at least 30 minutes a day.

Dr Selvan Muthusamy said, “Managing weight, blood sugar, blood pressure, and cholesterol is equally important. Taking prescribed medications consistently, participating in cardiac rehabilitation, and attending regular follow-up appointments all help reduce strain on the arteries and lower the risk of complications.”

In recent years, newer technologies have also been developed to address some of the mechanical drawbacks of traditional stents. One such innovation is the bioadaptor implant. Unlike conventional stents that remain permanently fixed, the bioadaptor is designed to change over time. After about six months of healing, it unlocks within the vessel wall and becomes a dynamic scaffold. This allows the artery to regain flexibility, stretch, and natural pulsation. Studies have shown improved blood flow, healthier artery lining, and more than 50 percent better long-term outcomes compared to standard stents.

Warning Signs To Detect Problems With Heart Stents

The most common cause of stent failure is restenosis, where tissue growth gradually narrows the artery again. Patients should pay close attention to symptoms such as chest pain or pressure, shortness of breath, unusual fatigue, a rapid heartbeat, nausea, sweating, or swelling in the legs. These signs may become more noticeable during physical activity.

Seeking medical help promptly when these symptoms appear is critical. Early detection can prevent more serious complications, including heart attacks, and allow doctors to intervene before the problem becomes life-threatening.
