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.

Lights will guide you home, but will it treat your mental illness? It could. According to new findings, changing the color of light could help treat mental illness. A psychiatric unit in Trondheim, Norway is testing how light could be used as a potential treatment for mental health conditions like psychosis and depression. The approach is simple, yet innovative that aims on changing the ward's design to help patients in their recovery. As night falls, filters are lowered over windows and lights are changed. This creates a soothing ambiance and eliminates the blue wavelengths that could disrupt body's internal clock.
The findings have been published in PLOS Medicine, that looked on the patients who were treated in the circadian-adapted ward. The study showed that these patients showed greater clinical improvement and less aggressive behavior. "Just by changing the light spectrum, we can improve the quality of treatment," said Havard Kallestad, a researcher at St Olavs hospital who led the study.
Researchers are now looking at its use for other healthcare areas, which means beyond the psychiatric wards. The UK's National Institute of Health and Care Research (NIHR) has also called for trials to see if this could "reset" the internal clocks of people who are living in care homes to reduce their behavioral disturbances, especially in dementia patients.
Professor Anthony Gordon of the NIHR said that it was about determining if light therapy could be used to reduce anxiety and improve sleep.

The psychiatric unit was divided in two identical halves with the same layout, staffing, and facilities. The key difference between the two was the evening light environment. One of the wards used blue-depleted lighting from 6pm onwards, where blinds and filters blocked similar light from windows and screens.
Whereas the other ward used standard hospital lighting and the unique design allowed researchers to study the impact of different lighting on patient recovery.
Circadian rhythm is the body's internal 24-hour clock that regulated the sleep-wake cycle, hormones, digestion, and temperature, which aligns them with day and light. It is primarily controlled by light-sensitive brain cells, or what people commonly call the 'body clock'.
Disruption in the cycle could link to various health issues, which includes mental health problems like depression and cardiovascular diseases. This is why the test in Trondheim could prove beneficial in treating patients across the spectrum of illness.

Dialysis patients who took daily fish oil supplements had a 43 percent lower risk of major cardiovascular events, according to a large international clinical trial jointly led in Australia by Monash Health and the School of Clinical Sciences at Monash University.
Published in The New England Journal of Medicine, the study found that participants who took four grams of fish oil each day experienced significantly fewer major cardiovascular events, including heart attack, stroke, cardiac death and vascular-related amputations than those who received a placebo.
The supplement contained the omega-3 fatty acids EPA and DHA, which are naturally found in fish oil.
Adjunct Professor Kevan Polkinghorne, a nephrologist at Monash Health and adjunct in the School of Clinical Sciences, led the Australian portion of the trial said: "Patients on dialysis have extremely high cardiovascular risk, and very few therapies have been shown to reduce that risk," Professor Polkinghorne said. "In a field where many trials have been negative, this is a significant finding.
"Dialysis patients typically have much lower levels of EPA and DHA than the general population. This may help explain the magnitude of benefit observed in this group."
He also noted that results applied specifically to people undergoing haemodialysis for kidney failure and the findings should not be generalized to healthy individuals or to other groups of patients.
Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.
These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Since many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.
Although the body can convert another type of omega-3, alpha-linolenic acid (ALA), into EPA and DHA, this process is not highly efficient. As a result, fish oil supplements may provide a convenient way to ensure optimal levels of omega-3s.
Some popular sources of Omega-3 include:
Earlier this month, Finance Minister Nirmala Sitharaman announced a surprising tax reduction for India's fishers and marine industry, and experts say it is good news for you too.
Until now, fish caught by Indian vessels beyond territorial waters and brought back to the country for mass consumption has been treated as import, attracting customs duties and integrated goods and services tax (GST).
The combined tax burden raises costs and compliance issues, which discouraged people from deep-sea and exclusive economic zone (EEZ) fishing as well as
However, during her Union Budget 2026 presentation, Sitharaman proposed that fish caught in the EEZ and high seas by Indian fishing vessels are treated as duty-free when brought into Indian ports and treated as exports when landed at foreign ports.
This means that the market availability for Omega-3 packed fishes including salmon, mackerel, tuna, herring and sardines will significantly increase as their existing steep prices see a tremendous fall.

Malaria infected an estimated 282 million people and caused about 6,10,000 deaths worldwide in 2024, according to the World Health Organization’s (WHO) latest World Malaria Report. The report placed strong emphasis on drug resistance, warning that it remains one of the biggest threats to global elimination goals.
WHO-recommended vaccines helped prevent roughly 170 million cases and one million deaths last year, which is about nine million more than the year before. Around 95 per cent of malaria deaths occurred in the African Region, with children under five forming the largest share.
Within the WHO South-East Asia Region, India represented 73.3 per cent of all malaria cases and 88.7 per cent of all malaria-related deaths. The report also underscored that the world is nowhere close to meeting the targets set under the Global Technical Strategy for malaria 2016–2030.
However, a group of University of Nottingham researchers have now found a key protein that is an enticing target for new antimalarial interventions. The study looked at a protein called Aurora-related kinase 1 (ARK1), which plays an important role in the parasite’s unusual cell division.
ARK1 helps control the parasite’s mitosis (cell division) and organizes a structure called the spindle, which separates genetic material so new parasites can form.
Scientists turned off the ARK1 gene using genetic engineering techniques to see what would happen. Without ARK1, the parasites could not form proper spindles and failed to reproduce, suggesting the protein could be a weak spot that future malaria treatment.
"What makes this discovery so exciting is that the malaria parasite's 'Aurora' complex is very different from the version found in human cells," senior author Rita Tewari said.
Anopheles stephensi is a malaria-transmitting mosquito originally found in South Asia. Unlike many other malaria vectors, it thrives in cities and breeds in man-made water sources such as storage tanks, containers, and discarded tyres. It can carry both Plasmodium falciparum and P. vivax parasites.
In recent years, this mosquito has spread into several African countries, where it adapts easily and shows resistance to multiple insecticides. This expansion has increased the threat of urban malaria outbreaks, as highlighted by the World Health Organization.
At present, Anopheles stephensi has been detected in nine African countries and is proving difficult to control due to widespread insecticide resistance.
The report noted that WHO approved the world’s first malaria vaccines in 2021, and 24 countries have now added them to their regular immunisation schedules. Dr Tedros Adhanom Ghebreyesus, WHO Director-General, said that new preventive tools provide reason for optimism, but many obstacles remain.
He pointed out the rise in cases and deaths, the pressure from drug resistance, and the impact of reduced funding. These factors could undermine the progress achieved over the last twenty years.
