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.
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 newly recognised form of diabetes is reshaping how scientists and doctors view the condition, particularly in countries like India. In 2025, global health authorities officially acknowledged Type 5 diabetes as a separate and distinct form of the disease.
This recognition ended decades of confusion around a type of diabetes that did not fit neatly into the existing categories of Type 1 or Type 2 diabetes. The formal classification, backed by the International Diabetes Federation and supported by research published in The Lancet Global Health, is expected to transform diagnosis, treatment, and long-term care for millions of people worldwide.
But what exactly is Type 5 diabetes, and how does it differ from the types of diabetes that are more widely known?
Type 5 diabetes is now recognised as a distinct form of the disease caused primarily by severe, long-term malnutrition, often experienced during childhood. This undernutrition can lead to profound insulin deficiency and an underdeveloped pancreas, resulting in significantly reduced insulin production.
Unlike Type 1 diabetes, which is autoimmune, or Type 2 diabetes, which is linked to insulin resistance, Type 5 diabetes arises from nutritional deficiencies that impair the pancreas’s ability to function properly.
It most commonly affects lean young adults in low-income regions. For years, people with this condition were misdiagnosed as having Type 1 diabetes or an unusual form of Type 2, often leading to inappropriate treatments that failed to address the root cause.
Symptoms of type 5 diabetes can resemble those seen in other forms of diabetes, such as excessive thirst, frequent urination, persistent tiredness, unexplained weight loss, blurred vision, and slow-healing wounds. However, they are often paired with indications of malnutrition, including a lean physique, delayed growth or puberty in young people, anemia, and recurring infections.
These arise from nutritional deficiencies during early life rather than solely from insulin resistance or autoimmune causes, and they usually present before the age of 30, according to the International Diabetes Federation.
Researchers have been studying this condition for decades, particularly in parts of Asia and Africa. Yet, without official recognition, the disease remained poorly understood, and patients were rarely diagnosed correctly. Experts argued that grouping these patients under existing categories obscured the true cause of their illness.
The 2025 classification now formally separates Type 5 diabetes from other types, making it easier to study, identify, and manage. In India, where diabetes prevalence is already high, this recognition is particularly relevant. Tens of millions of people live with diabetes in the country, many of whom remain undiagnosed. Type 5 diabetes highlights a different pattern: it develops not from excess calories, but from too little nutrition during childhood, creating a double burden in regions where obesity and undernutrition coexist.
Although there is no new treatment specifically for Type 5 diabetes yet, official recognition marks a major step forward. Doctors can now approach lean patients with a history of malnutrition more carefully, avoiding a “one-size-fits-all” approach. Clearer classification could lead to better guidelines, more personalised care, fewer complications, and improved long-term outcomes.
Experts believe that understanding the role of childhood undernutrition in diabetes could eventually reshape how we prevent, monitor, and manage the condition—something countries like India urgently need as diabetes numbers continue to rise.

An early sign of dementia can sometimes look like a common winter-related issue. When this symptom appears along with other warning signals, it may be wise to speak to a doctor. Dementia is a syndrome marked by a collection of related symptoms that point to a gradual decline in brain function. Over time, this can affect memory, behaviour, thinking, and even movement. In its early phase, however, dementia often shows up through subtle changes that are easy to overlook or mistake for something less serious.
Dementia UK notes that one possible early indicator of dementia is “low mood, anxiety or depression”. Its specialists explain: “In the early stages of dementia, people often begin to notice symptoms that interfere with day-to-day life.” The difficulty is that low mood or depression can also be linked to seasonal affective disorder (SAD), a form of depression that tends to appear during winter and ease as the days become longer and brighter.
The NHS lists the following possible symptoms of SAD:
The organisation explains: “A person experiencing early symptoms of dementia may notice these changes themselves, or they may be picked up first by family members, friends or colleagues. Memory problems are not always obvious in the early stages of some types of dementia, such as frontotemporal dementia, where changes in behaviour and personality may appear first.
“People with young onset dementia, where symptoms begin before the age of 65, are also less likely to have memory loss as an early symptom.”
The charity also points out that emotional changes can be linked to two specific types of dementia. In vascular dementia, a person may experience “changes in mood, behaviour and personality”, while Lewy body dementia can cause “mood changes, including anxiety and depression”.
That said, it is often difficult to know at first whether dementia is the cause of these warning signs. Dementia UK advises: “Many symptoms associated with dementia can also be caused by other physical or mental health conditions, such as thyroid disorders, menopause, vitamin B12 deficiency, depression, anxiety, work-related stress or relationship difficulties.
“This means that experiencing symptoms linked to dementia does not automatically mean someone has the condition. However, if you or someone close to you is showing signs or symptoms of dementia, it is important to visit a GP to understand what might be causing them.”
If you or someone you know is showing symptoms that resemble dementia, seeking advice from your GP is an important first step.

Gonorrhea poses a far more serious challenge than many realise. Over the years, doctors treating the infection have seen their treatment choices steadily shrink. The bacteria responsible, Neisseria gonorrhoeae, has repeatedly adapted to antibiotics, rendering many once-reliable drugs ineffective. As a result, clinicians have been forced to depend heavily on a single injectable medication, a situation that has raised growing concern.
That dependence is becoming increasingly risky. Data from the US Centers for Disease Control and Prevention show that reported cases of gonorrhea, chlamydia, and syphilis have climbed by nearly 90% since 2004. In 2023 alone, the country recorded more than 2.4 million cases of sexually transmitted infections.
This month, however, marked a significant shift. The US Food and Drug Administration approved two new oral antibiotics to treat gonorrhea: zoliflodacin and gepotidacin. These approvals represent the first entirely new gonorrhea treatments in more than three decades.
“These approvals mark a significant milestone for treatment options for patients with uncomplicated urogenital gonorrhea,” said Dr Adam Sherwat of the FDA in an official statement.
If left untreated, gonorrhea can lead to serious complications, including pelvic inflammatory disease, infertility, and in rare cases, infections that spread to the joints or bloodstream, as per Cleveland Clinic. Many people experience no symptoms at all, allowing the infection to spread quietly. Despite years of research, there is still no licensed vaccine, leaving antibiotics as the primary line of defence.
The newly approved treatments offer a fresh sense of hope. Zoliflodacin, developed by the nonprofit Global Antibiotic Research and Development Partnership in collaboration with Innoviva Specialty Therapeutics, is designed as a single-dose oral medication. Gepotidacin, developed by GSK, is taken in two doses and is also approved for treating certain urinary tract infections.
Both medicines eliminate the need for injections, a shift that could make treatment simpler and more accessible, particularly in settings where access to clinics is limited.
As per Medscape, clinical trial results for both drugs have been encouraging. Zoliflodacin was tested in a large international study involving more than 900 participants across Europe, Africa, Asia, and the US. The drug successfully cured about 90.9% of patients, a rate comparable to the 96.2% success rate of the current injectable standard. Most reported side effects were mild.
Gepotidacin showed similarly strong results in a separate Phase 3 trial that included around 600 patients from six countries. The cure rate reached 92.6%. Some participants reported digestive issues, but these effects were generally described as mild.
Importantly, both medications were effective against strains of gonorrhea that no longer respond to older antibiotics. That said, public health experts stress that these drugs are not a permanent solution.
“Bacteria are smart. They can pass resistant mechanisms between each other,” said Dr Manica Balasegaram of the Global Antibiotic Research and Development Partnership, speaking to CNN.
Several uncertainties remain. Neither drug has yet shown strong effectiveness against throat infections, known as pharyngeal gonorrhea, which are more difficult to detect and treat. There is also ongoing debate about how best to use the new medications. Some experts argue they should be reserved as last-line treatments, while others believe earlier use could help slow resistance.
Dr Tereza Kasaeva of the World Health Organization described the approvals as “an important and timely development” amid rising global infection rates and limited treatment options, according to The Guardian.
For now, the new drugs provide much-needed breathing room. Whether that progress holds will depend on careful prescribing and close monitoring of how resistance evolves.
