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 GP has shared an urgent alert about a clearly visible cancer symptom that many women may be brushing aside. The doctor stressed that this particular sign needs to be checked without delay. Ahead of Cervical Cancer Prevention Week, beginning January 19, as per Mirror, Dr Rupa Parmar outlined key warning signs of the disease and cautioned that one in three women are skipping their routine cervical screening appointments.

She also highlighted that some of the most common symptoms are often dismissed. One such sign is weight loss, which many women may wrongly link to cutting back after festive overindulgence or returning to a normal routine in January.

Women Urged Not To Ignore This Obvious Cancer Symptom

Dr Parmar, a GP and Medical Director at Midland Health, explained: “Cancer cells interfere with the body’s ability to properly absorb fats, proteins and carbohydrates from food. As a result, calories are burned more quickly, leading to weight loss. Unexplained weight loss is often the most obvious sign of cancer and should always be checked straight away.” She added that sudden weight loss is not exclusive to cervical cancer and is recognised as a general warning sign across several types of cancer.

Cancer Research UK also notes that weight loss is common among people with cancer and can be one of the first reasons someone seeks medical advice. The charity points out that lung cancer and cancers of the upper digestive system are among those most often linked to weight loss.

Dr Parmar also highlighted other possible signs of cervical cancer.

Pain During Sex

Pain during intercourse can be caused by issues such as vaginal dryness, infections or skin conditions, Dr Parmar said. However, if pain is new and wasn’t present before, it could be linked to cervical cancer, as a growing tumour may begin to affect nearby tissues.

Recurrent UTIs

Experiencing three or more urinary tract infections within a year could indicate an underlying problem, including cervical cancer. Dr Parmar clarified that UTIs do not cause cancer, but repeated infections may occur if a tumour has advanced and is pressing on or blocking the urinary tract.

Pelvic Pain

Ongoing and severe pain in the lower back or pelvic area with no clear explanation can be another warning sign, particularly when combined with other symptoms. As cervical cancer advances, this pain may intensify and can worsen during sex, urination or bowel movements.

Vaginal Bleeding

Bleeding that is unusual for you should never be ignored. This includes bleeding during or after sex, spotting between periods, bleeding after menopause, heavier-than-normal periods, or cycles that last longer than usual. These changes can signal that something may be wrong.

Discharge

Changes in vaginal discharge can also point to problems with the cervix. An increase in discharge, an unusual smell, changes in colour, or the presence of blood may occur once cancer has begun to affect nearby tissues.

If you notice any of these symptoms, it’s important to speak to a doctor as soon as possible.

Dietary supplements are already part of many people’s daily habits, especially at the start of the year when health goals are front of mind. What many may not realise is that there is one supplement the Government says everyone should be taking through the colder months. Health guidance recommends a small daily dose of vitamin D for everyone in the UK from around October to late March, as sunlight levels are too low for the body to produce enough on its own. Vitamin D supplements are easy to find and come in several forms, including tablets, capsules, gummies and liquid drops. Here is a simple breakdown of what vitamin D is and why it matters.

What Is Vitamin D?

Vitamin D is an essential nutrient that helps control calcium and phosphate levels in the body. These minerals work together to support healthy bones, teeth and muscles.

When vitamin D levels are too low, children can develop rickets, a condition that causes bones to become soft and weak. In adults, deficiency may lead to osteomalacia, which can result in bone pain, muscle weakness and a higher risk of fractures.

What Does The Government Recommend?

UK health advice states that everyone should take a daily supplement containing 10 micrograms, or 400 international units, of vitamin D during autumn and winter.

This amount is considered sufficient to maintain general wellbeing, particularly bone and muscle health, at a time of year when sunlight alone is not enough for vitamin D production.

Official guidance explains: “This advice is particularly important for people who have little exposure to sunlight during spring and summer, including those living in residential or nursing care homes, people in prisons, and individuals who regularly wear clothing that covers most of their skin when outdoors.

“These groups are at greater risk of vitamin D deficiency. People with darker skin tones, such as those from African, African-Caribbean or South Asian backgrounds, may also struggle to get enough vitamin D from sunlight alone.

“All of these groups are advised to take a vitamin D supplement throughout the year, in line with standard government dietary guidance.”

A scheme that once allowed eligible people to apply for free vitamin D supplements was available previously, but this programme ended in 2021.

Where Can You Get Vitamin D?

Between late March or early April and the end of September, most people can produce enough vitamin D naturally through sun exposure. The body creates vitamin D when UV-B rays from sunlight reach the skin.

Vitamin D is also present in certain foods, including oily fish, red meat, egg yolks, and fortified products such as some spreads and breakfast cereals.

Supplements can be bought easily from pharmacies and supermarkets, with some costing as little as 2p per day. Vitamin D3 is generally the preferred form.

Can You Get Too Much Vitamin D?

Yes. While sunlight does not cause vitamin D overdose, taking excessive supplements over a long period can lead to a build-up of calcium in the body. This can weaken bones and cause damage to the kidneys and heart.

For most people, a daily intake of 10 micrograms is sufficient. NHS advice states that adults should not take more than 100 micrograms, or 4,000IU, per day, as higher amounts may be harmful.

If a doctor has advised a different dosage based on your individual health needs, it is important to follow their guidance.

Concerns around fertility and vaccines often surface when people plan a family, and the HPV vaccine is no exception. Many women and men worry that getting vaccinated today could affect their ability to conceive later in life. Medical experts, however, say this fear is misplaced. According to fertility specialists, there is no evidence linking the HPV vaccine to reduced fertility. In fact, the vaccine may play a quiet but important role in protecting reproductive health over the long term.

Does The HPV Vaccine Affect Fertility?

The short and clear answer is no. The HPV vaccine does not negatively affect fertility in women or men. Dr. Madhu Patil, Consultant and Fertility Specialist at Motherhood Fertility and IVF, Sarjapur, Bangalore, explains that there is no scientific proof showing the vaccine causes fertility problems of any kind.

She notes that concerns often arise from misinformation rather than medical data. Extensive research and global vaccination programmes have consistently shown that people who receive the HPV vaccine do not experience reduced chances of conceiving in the future.

How HPV Infection Can Threaten Future Fertility

While the vaccine itself does not harm fertility, an untreated HPV infection can. HPV is the leading cause of nearly all cervical cancer cases. As per Dr Patil, “treatment for cervical cancer often involves procedures such as cone biopsy or LEEP, which can weaken the cervix. In more advanced cases, radiation or chemotherapy may be required.”

These treatments can reduce a woman’s ability to conceive and, in some cases, make it difficult to carry a pregnancy to full term. By preventing HPV-related cancers in the first place, the vaccine helps preserve the reproductive system and lowers the risk of fertility-compromising treatments later in life.

Why The HPV Vaccine Supports Reproductive Health

Dr. Patil points out that the HPV vaccine should be viewed as a protective measure rather than a risk. By stopping high-risk HPV strains from causing cancer or precancerous changes, the vaccine helps maintain cervical health. A healthy cervix and reproductive system are key factors in natural conception and safe pregnancies.

In this way, the vaccine indirectly supports fertility by reducing the likelihood of medical interventions that could interfere with reproductive function.

When Should the HPV Vaccine Be Taken?

Health experts recommend starting HPV vaccination at ages 11 or 12. At this stage, the immune response is strongest, and the vaccine offers protection well before any potential exposure to the virus. Dr. Patil strongly encourages parents to consult a gynaecologist and consider timely vaccination for their children.

That said, adults who missed vaccination earlier can still benefit. Many women and men receive the vaccine later in life after discussing it with their doctor.

Why Men Should Also Get The HPV Vaccine

The HPV vaccine is not only for women. Dr. Patil stresses that men should also be vaccinated, as HPV can cause cancers and genital warts that affect sexual health. Vaccination in men also reduces transmission to partners, adding another layer of protection for couples planning a family.

By limiting the spread of HPV, vaccination helps safeguard the reproductive and sexual health of both partners.

There is no evidence that the HPV vaccine reduces fertility. On the contrary, it helps prevent cancers and medical treatments that can threaten the ability to conceive or carry a pregnancy. Experts advise speaking with a gynaecologist, understanding the benefits, and making an informed decision based on medical facts rather than fear.
