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.

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.

What Are Fish Oil Omega-3s?

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:

• Salmon
• Cod Liver Oil
• Algae Oil
• Oysters
• Nuts and seeds, such as flaxseeds, chia seeds, and walnuts
• Plant oils, such as flaxseed oil, soybean oil, and canola oil
• Fortified foods, such as eggs, yogurt, juices, milk, etc.

Budget 2026: Cheaper Fish In India

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.

What Are Anopheles Stephensi Mosquitoes?

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.

Malaria Vaccines

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.

Men planning to conceive should practise caution while consuming antioxidant supplements, as excessive intake may affect sperm and early craniofacial development in babies, a Frontiers in Cell and Developmental Biology study shows.

Antioxidants are often promoted as powerful supplements that can help protect the body from chronic conditions, including cancer, chronic obstructive pulmonary disease and dementia.

However, researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) found that consuming high levels of the antioxidant compounds N-acetyl-L-cysteine (NAC) and selenium (Se) can alter skull and facial shape in female children, even though the treated fathers did not exhibit obvious health problems.

Dr Michael Golding, a professor in the VMBS’ Department of Veterinary Physiology and Pharmacology, whose research team made the discovery said: "We know alcohol causes oxidative stress and we were looking to push back on it by adding a supplement known to lower oxidative stress.

"When we realized that offspring born to males that had only been given NAC were displaying skull and facial differences, it was a surprise because this molecule is universally thought to be good.

“When we sat down to think it through, we realized that it makes sense — you take a multivitamin to ensure that you’re in balance, but if the thing that you’re taking to ensure you’re in balance is unbalanced (the dose of antioxidants is too high), then you’re not doing a good thing.

“Sperm health is another performance metric; it’s just not one that we think about in everyday life. If you’re taking a high-dose antioxidant, you could be diminishing your reproductive fitness, and part of the journey toward the bad outcome is going to be the effects on the offspring.”

What Are Antioxidants?

Antioxidants are important because they protect the fundamental structure of the human body, cells. They safeguard an individual's DNA and proteins from the damage caused by free radicals.

Research has shown that a diet high in antioxidants may help individuals prevent chronic diseases and mental health issues. But on the contrary, having too many antioxidants in your body could confuse your cells' responses, leading to more damage than intented.

How Do Antioxidants Protect Your Body?

Antioxidants basically neutralize free radicals in the body. These free radicals are extra atoms that are produced during the body's internal processes and also by some external factors.

Overproduction of these free radicals, during the process of oxidation in the human body, damages cell membranes and other structures, including cellular proteins, lipids and DNA. Oxidation can be exacerbated by stress, smoking, alcohol, sunlight and pollution.

In the long run, they can lead to diseases such as cancer and heart diseases. It is pertinent to note that the brain is prone to oxidative stress due to its high metabolic activity. Here, the role of antioxidants becomes particularly important as they fight oxidative stress which could otherwise lead to stroke, traumatic brain injury or neurodegenerative diseases like Alzheimer's.

If you take large amounts of antioxidants, then it could hamper the cell's defence mechanisms and normal signalling. Different types of antioxidants also have different properties, so they may not be interchangeable. Therefore, health experts advise people to be mindful of the amount of antioxidant-rich food they are including in your diet. Notably, studies have found that antioxidant supplements have a lower impact such as natural food items.
