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.

Massive wildfires have ravaged several parts of Canada and other regions of the world, filling the air with hazardous smoke. This has triggered health warnings far beyond the fire zones.
While most people experience immediate breathing problems during and after wildfires, experts say that some health effects can persist long after the skies clear.
Wildfire smoke is composed of harmful gases and microscopic particles known as PM2.5. These tiny particles are small enough to travel into our lungs and enter the bloodstream, where they can trigger inflammation throughout the body.
Unlike typical air pollution, wildfire smoke also contains toxic substances released from burning homes, plastics, furniture, vehicles, electronics, and industrial materials, making prolonged exposure particularly harmful.

Prolonged exposure to wildfire smoke can have long-term effects on the respiratory system. Possible health effects may include:
Children, older adults, and people with existing lung conditions face the highest risk because their lung function is already compromised.

The tiny particles in wildfire smoke don't just stay confined to the lungs. Once they enter the bloodstream, they can affect the cardiovascular system. In the long run, research says wildfire smoke exposure can lead to:
With frequent incidences of wildfires, scientists are looking into how wildfire smoke affects the brain. Emerging evidence suggests smoke exposure may contribute to:
Wildfires can affect mental health in more than one way. Besides the stress of evacuation and property loss, smoke exposure itself may contribute to mental health problems directly. One is at the risk of the following mental health issues after exposure:
Communities repeatedly exposed to wildfire events may experience prolonged psychological distress that could often go undetected.
Growing evidence suggests that long-term exposure to wildfire smoke may increase the risk of several cancers. Studies have reported possible associations with lung cancer, breast cancer, colorectal cancer, bladder cancer, and certain blood cancers
Although researchers say more studies are needed to establish a direct cause-and-effect relationship, the findings highlight the importance of limiting repeated smoke exposure.

Pregnant women are among the groups considered most vulnerable to wildfire smoke. Research suggests exposure during pregnancy may increase the risk of preterm birth, low birth weight and other pregnancy complications.
Healthcare providers recommend minimizing outdoor exposure whenever air quality deteriorates.
Even after visible smoke disappears, harmful particles may remain in the air. Experts recommend:

When we think of dialysis, we often picture a machine filtering blood and keeping patients alive. What rarely comes to mind is the small blood vessel in the arm that makes the entire process possible.
For every patient on haemodialysis, the arteriovenous (AV) fistula is quite literally a lifeline. Without it, dialysis cannot be performed effectively. Yet, despite being one of the most important parts of treatment, fistula care remains one of the least understood aspects of kidney disease.
This silent gap in awareness is costing patients their lifeline.
India adds nearly 2.2 lakh new patients with end-stage kidney disease every year, creating a demand for over 3.4 crore dialysis sessions annually.
One of the biggest challenges we see in clinical practice is that patients often seek medical help only after the fistula has already stopped functioning.
The warning signs are usually ignored.
The vibration over the fistula becomes weaker. The arm begins to swell. Bleeding continues longer than usual after dialysis. Needle insertion becomes increasingly difficult. Sometimes dialysis itself becomes less effective.
By the time patients reach an interventional radiologist or vascular specialist, the fistula may already have developed significant narrowing (stenosis) or complete blockage.
Unfortunately, many of these complications are preventable if detected early.
In our experience, nearly 30% of patients eventually lose their fistula because they report too late, when timely intervention could have salvaged access.

Unlike diabetes or blood pressure, there is no widespread public awareness around fistula surveillance.
Many dialysis patients receive instructions on medicines and dialysis schedules but very little education on how to examine their fistula every day.
There is also no universally implemented patient education protocol across dialysis centres, leading to inconsistent awareness about fistula care.
The result is simple: patients unknowingly damage the very access that keeps them alive.
Patients should examine their fistula daily.
A healthy fistula has a continuous buzzing sensation or “thrill.” If this vibration becomes weak or disappears, medical attention should be sought immediately.
Similarly, swelling of the arm, redness, prolonged bleeding after dialysis, pain around the fistula, or difficulty during needle insertion should never be dismissed as routine.
These are early warning signs - not inconveniences.

These small daily habits can often extend the life of a fistula by years.
One of the greatest advances in dialysis access care is that many fistula problems no longer require open surgery.
If narrowing is detected early, minimally invasive image-guided procedures such as fistuloplasty (balloon angioplasty) can restore blood flow, preserve the existing fistula and help patients continue dialysis without interruption.
The key, however, is timing.
A fistula that is evaluated early is often salvageable.
A fistula ignored for weeks may not be.
Every successful fistula represents months of planning, surgery and healing. Losing it means additional procedures, temporary catheters, higher infection risk, increased costs and emotional distress for patients already living with chronic kidney disease.
As doctors, we have become increasingly skilled at creating dialysis access.
The next challenge is ensuring patients know how to protect it.
Because for someone living with kidney failure, the fistula is not just another blood vessel.
It is the lifeline that keeps life moving.

GLP-1 drugs such as Ozempic, Wegovy, Mounjaro and liraglutide, best known for regulating appetite and aiding weight loss, may also help reduce symptoms of binge eating disorder (BED), which affects more than 17 million people worldwide, according to a new study.
The systematic review and meta-analysis, published in the journal eClinicalMedicine, found that GLP-1 drugs, with semaglutide as its key ingredient, reduced binge eating episodes, loss-of-control eating and emotional eating, highlighting their potential role in treating binge eating disorder alongside obesity.
Binge eating disorder affects over 17 million people globally, and around two-thirds of people with the condition also live with overweight or obesity. It is also common among individuals seeking weight-loss treatment.
"Binge eating disorder, where people regularly eat an excessive amount of food while feeling they have lost control, is common and highly impairing, affecting over 17 million people worldwide," said lead author Dr Ilaria Costantini from the Psychiatry Department at University College London (UCL), UK.
"But treatment options are limited and there are currently no approved medications, so there remains a need for better ways to help people living with this condition. We found evidence that weight loss drugs may help to manage some key symptoms of binge eating disorder," Costantini added.

The researchers analyzed 25 randomized controlled trials conducted across 12 countries on four continents, involving 8,069 participants.
The trials evaluated GLP-1 drugs that target the appetite-regulating hormone GLP-1, including semaglutide (marketed as Ozempic or Wegovy), tirzepatide (Mounjaro) and liraglutide.
These medications suppress appetite by acting on the central nervous system and insulin secretion, delay stomach emptying, and may also influence brain pathways involved in reward and impulse control.
Compared with placebo or other treatments, people taking GLP-1 drugs reported:

The researchers also found that participants taking GLP-1 drugs reported greater cognitive or dietary restraint, meaning they made more deliberate efforts to limit what they ate.
The benefits extended beyond weight loss, with improvements seen in several behaviors associated with binge eating disorder.
While increased dietary restraint was observed, the researchers cautioned that it remains unclear whether this represents healthy self-regulation or a more rigid, potentially harmful eating pattern that could worsen binge eating over time.
"From the evidence available, we cannot say whether the increase in dietary restraint reflects a positive and helpful form of self-regulation or if it is a more dysfunctional pattern of eating. We hope that future research can clarify whether or not taking weight loss drugs might contribute to more pathological forms of eating restriction such as meal skipping," said Izzy Emptage from UCL Psychiatry.
The researchers said GLP-1 drugs could become an important addition to treatment plans for binge eating disorder when used alongside psychological therapies and social support.
However, they also highlighted important limitations. Most of the studies included in the review had a high risk of bias, were funded by pharmaceutical companies, and rarely included participants with a clinical diagnosis of binge eating disorder, reducing the certainty of the findings.
"GLP-1s may offer a promising additional treatment option for people living with both binge eating and obesity," the researchers said, while stressing that these drugs "should not be viewed as a standalone solution to binge eating disorder."
They added that larger, independently funded clinical trials are needed before these medications can be routinely recommended for treating binge eating disorders.
