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.

Of the many medicines that we consume on a day to day basis, we are not aware of how gradually they are actually making our health worse. One medicine that is common in many households, especially in India households, as points Dr Obaidur Rahman, Ortho and Sports Surgeon is pantoprazole, popularly sold under the name PAN40, PAN Top or PAN D. These medicines are used to treat and relieve symptoms of heartburn, which is a common symptom of acid reflux and GERD.
"A patient came to me, he was an 80-year-old male. He has a habit of taking this tablet regularly, and because of that he suffered an osteoporotic fracture. This means he fell while walking and fractured," points out Dr Rahman.
He says that many people, old and young, alike, have a habit of taking this pill like a multivitamin. In fact, they have substituted with pro and prebiotics and assume that it helps with digestion. However, he points out, "If you take this regularly, your gastric mucosa stops responding against proper acid production. And there is also an impairment in digestion."
He says that in clinical practice, it has been found that this common household medicine, which is often procured as over-the-counter or OTC medicine, meaning, without prescription, could cause Vitamin B12 deficiency, and magnesium deficiency.
As per a 2023 study published in the journal BioMed Research International, pantoprazole cause bone loss, which could be prevented by adding octreotide.
The study analyzed the serum levels of calcium, phosphorus, and ALP before starting the treatment, and at the end of 12 weeks of treatment on pantoprazole, significant decline in calcium levels were noticed, as compared with other groups. The study also found that octreotide significantly prevented the effect of pantoprazole on the serum levels of calcium and ALP.
The study also found that pantoprazole decreased femoral bone density and femoral BMAD. Besides this, another decrease was found in the femoral bone weight and volume as well as the trabecular volume.
Another study from 2021, published in the European Journal of Clinical Pharmacology pointed out that 12 patients had major fractures and showed changes in serum Mg2+ and Ca2+ levels over a period of 1 month as well as the animal study also showed ionic imbalance over 8-week treatment with pantoprazole. Bone density measured for the patient at the end of the 1-month treatment was found to be in the osteopenic category, together with the animal study which showed a decrease in femur bone strength for the animal treated with pantoprazole over a period of 8 weeks.
Pantoprazole contain Proton Pump Inhibitor (PPI), and prokinetic, long-term use of PPIs is associated with the risk of bone fracture. However, alternatives like Histamine H2-receptor antagonists or H2 blockers are effective alternative that do not cause bone loss, notes a 2020 study published in journal Bone, titled Comparative analysis of the risk of osteoporotic fractures with proton pump inhibitor use and histamine-2 receptor antagonist therapy in elderly women: A nationwide population-based nested case-control study.
Famotidine (Pepcid, Calmicid, Fluxid, Mylanta AR) is a potent H2 blocker used to manage acidity and heartburn. Studies show that famotidine is not thought to raise the risk of osteoporosis.
Other options: Ranitidine (Zantac - where available, as it was withdrawn in some markets due to safety concerns) and Nizatidine are other H2 blockers.

This flu season could be brutal, say the early clues that scientists have gathered. This comes as the world already struggles keeping up with the new variants of COVID, however, the COVID rates in the US appears to be low. Though researchers are expecting the virus to circulate more widely in the coming months as people gather for holidays.
This is also the time for common cold. Dr William Schaffner, an infectious disease specialist at Vanderbilt University Medical Center tells the New York Times that if you feel ill, but your symptoms remain only above the neck, that is, a stuffy nose, a sore throat, then it could just be a common cold.
However, if the symptoms lead to hacking cough, and down the neck, which makes your muscles ache and body tired, that it could be a flu or COVID. Due to the similarities in the symptoms, even infectious disease specialists also struggle to tell the difference.
How it begins: Initially, symptoms of COVID can mimic flu-like symptoms
The biggest difference here is the dry and persistent coughing, which when you have a cold will not be dry in nature.
Since the pandemic, Covid has blurred the lines between seasonal infections. Current strains can trigger flu-like fatigue, fever, and cough. But the loss of taste or smell and digestive issues are stronger indicators of Covid.
For confirming COVID, test is the only key. There are now at-home tests available online and at drugstores too. An at-home test could detect both, a flu and COVID.
How it begins: The symptoms of common cold starts gradually.
Here, the biggest difference is also in cough, which is often mucus-filled and chesty. Whereas in COVID, the cough is dry.
How it impacts? While it is annoying in the beginning, especially due to the blocked nose and ears, the congestion clears up overtime and usually doesn’t stop daily activities.
Colds typically start with a tickle in the throat or pressure in the ears before progressing to nasal congestion and cough. Most people can carry on with their routines despite the discomfort.
How it starts? In many cases, the flu may catch you out of the blues, many describe the onset as sudden.
While the cough here is also dry in nature, which may make one get confused with COVID, there is no razor-blade like symptom, which can be used as a marker to differentiate.
Unlike a cold, flu can leave you feeling completely wiped out. Body aches and high fever are distinguishing features, and recovery often takes several days of rest.

An antibiotic routinely used for acne has been linked to a lower likelihood of developing schizophrenia. A new investigation from the University of Edinburgh found that adolescents receiving mental health care who were given doxycycline had a reduced chance of being diagnosed with schizophrenia as adults, compared with those who were prescribed other antibiotics.
Although these early findings cannot confirm that doxycycline prevents schizophrenia, the researchers suggest that its influence on immune activity, inflammation, and programmed cell death may help protect the brain from changes associated with the disorder. “Because this research relies on observational records, it cannot prove that doxycycline directly lowers the risk of schizophrenia, so more studies are needed,” the authors explain.
“Even so, the results raise the possibility that doxycycline could play a role in lowering schizophrenia risk among young psychiatric patients and open new avenues for prevention-focused mental health research.”
Schizophrenia is a severe psychiatric disorder that affects about 23 million people worldwide, with most cases identified during late adolescence or early adulthood. The illness can appear suddenly and may bring on psychosis. Typical symptoms include ongoing delusions, hallucinations, disorganized thoughts, restlessness, or withdrawal from others. According to the World Health Organization (WHO), more than two out of three people experiencing psychosis lack access to specialized mental health services.
Doxycycline is a broad-acting antibiotic commonly given to teenagers for acne. Some recent research suggests it may also offer certain protective effects for the brain, as it is able to cross the blood-brain barrier. In 2024, Science Alert reported on a Danish study showing that this brain-penetrating antibiotic was associated with a lower likelihood of schizophrenia patients later receiving disability benefits, hinting at how the illness might affect their daily functioning.
To explore this further, child and adolescent psychiatrist Ian Kelleher from the University of Edinburgh led a large international team in reviewing data from more than 56,000 people born in Finland between 1987 and 1997. All had used mental health services in their youth and had been prescribed antibiotics during that time.
The analysis showed that those given doxycycline had a 30 to 35 percent lower chance of developing schizophrenia over the following decade, compared with individuals who had taken other antibiotics. The risk dropped from 2.1 percent in the non-doxycycline group to 1.4 percent in those who used doxycycline.
The research team found that taking doxycycline was linked to a 30 to 35 percent reduction in schizophrenia diagnoses over ten years. One theory is that doxycycline may clear an infectious agent that contributes to schizophrenia. Another possibility is that it directly affects inflammation and nerve pathways inside the brain.
Other antibiotics offer hints as well. A 2019 study using stem cells from people with schizophrenia and healthy volunteers showed that minocycline can reduce excessive loss of synapses, a process thought to play a part in schizophrenia. Since both minocycline and doxycycline belong to the tetracycline family, they may share similar properties. Using Finland’s health records, Kelleher’s team noted that nearly half of all psychotic disorders in the population occurred in individuals who had visited adolescent psychiatric services.
The researchers believe this stage of life may offer a valuable period for early intervention, where medications like doxycycline might help reduce the chance of the illness progressing. “Nearly half of the people who develop schizophrenia had earlier contact with child and adolescent mental health services for other issues,” Kelleher says.
“At the moment, we do not have any proven ways to lower the risk of schizophrenia in these young people, which makes these findings encouraging.”
Doxycycline is available in two forms, doxycycline monohydrate and doxycycline hyclate, though both tend to cause similar reactions. This list does not include every possible side effect, so consult your medical provider if you are unsure about anything you notice while taking the medication.
Mild doxycycline side effects include:
Rare but serious doxycycline side effects include:
Always speak with your healthcare professional before starting or stopping any medication.
