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.

Chronic pelvic pain in adulthood may have warning signs that appear much earlier in life. A new study suggested that reproductive and gynecological health problems during adolescence could identify people at higher risk years before chronic pain develops.
The study, carried by The Lancet Regional Health – Americas, analysed health data of nearly half a million people in Ontario, Canada, following them from adolescence into adulthood.
The researchers found that after 10 years into adulthood, chronic pelvic pain affected 28% of people who had sought healthcare for gynecological or reproductive health problems during their teenage years, compared to about 15% among those without such health issues during adolescence.
In a nutshell, the rate of chronic pelvic pain was 41% higher among people who had earlier gynecological or clinical visits due to reproductive issues.

The researchers used population-based health data held by ICES and followed people from adolescence into adulthood. The analysis also considered other health problems and healthcare use during adolescence.
The findings also indicated that teenagers who had sought care for gynecological or reproductive problems were also more likely to have gastrointestinal problems, mental health conditions and chronic pain in other parts of the body.
“We asked a simple question: Were there signs, years earlier, that someone was on a path toward chronic pelvic pain? This study shows that indeed, the gap between those affected by CPP was already visible early in adulthood and grew over time,” said lead author Shay Freger, a PhD candidate in McMaster University's Department of Obstetrics and Gynecology.

Chronic pelvic pain refers to persistent pain in the lower abdomen or pelvic region that can continue for months or years.
It can affect everyday life, education, work, relationships and mental health. Researchers also identified that pelvic and menstrual symptoms during adolescence can sometimes be dismissed as a normal part of growing up, even when the pain is severe or persistent. This could discourage a person to seek medical help.
The findings suggest that these symptoms could offer doctors and healthcare experts a key opportunity to identify patterns of certain health conditions earlier in life.
“What is important about this study is that the warning signs were not limited to reproductive health alone,” said Mathew Leonardi, senior author and associate professor in McMaster’s Department of Obstetrics and Gynecology.
“It suggests that adolescent menstrual and pelvic health may be part of a broader health picture that deserves earlier attention and more integrated care.”
The study just noticed an association, but it does not establish that adolescent gynecological or reproductive problems are the direct reasons behind chronic pelvic pain decades later in life.
Instead, the researchers say the findings indicate that healthcare providers may already be seeing patterns during adolescence that could be linked with greater vulnerability to chronic pain and other disorders in adulthood.
The researchers also said that recognising these patterns earlier could help shift pelvic pain care from treating to identifying and addressing problems before they become persistent.

As pollution season creeps back in Delhi, N95 masks outdoors and air purifiers are once again most likely to become the primary go-to protective measures for the public.
Both are known to lower exposure to harmful particles significantly, but neither can completely nullify the health risks of polluted air. So before you invest in an air purifier or buy a dozen N95 masks, understand how much you will be protected as you step out during smog everyday.

A properly fitted N95 respirator can filter at least 95% of airborne particles under standard environment. That makes it substantially more protective against fine particulate matter like PM2.5 than regular surgical or cloth masks.
But just wearing an N95 does not mean you are breathing toxins-free air. Its effectiveness depends heavily on fit. Gaps around the nose, cheeks or chin can let polluted air to bypass the filter.
An N95 also does not protect equally against every pollutant. It is designed primarily to filter particles, not gases like nitrogen dioxide or ozone. So if you spend most of your time outdoors during severe pollution, wear a well-fitted, certified respirator to reduce exposure.
Protection from PM2.5 is key as these particles are small enough to seep deep into your lungs and, in some circumstances, even cross over to enter the bloodstream. Long-term exposure to PM2.5 has been associated with cardiovascular disease, respiratory disease and other serious health problems.
The effectiveness of an air purifier depends significantly on the purifier, the size of the room and how it is used. A purifier equipped with a HEPA filter can remove fine particles from indoor air. When outdoor PM2.5 levels are high and polluted air enters homes through windows, doors and ventilation systems, this could be one of the best ways to protect yourself.
However, simply switching on a purifier in a large room does not guarantee clean air. The purifier needs to have sufficient clean air delivery rate (CADR) for the size of the room.
Keeping doors and windows closed during periods of extreme outdoor pollution can also help reduce the amount of polluted air entering. Filters need to be replaced according to the manufacturer's recommendations because a heavily loaded filter can reduce performance.

One of the limitations is that HEPA filtration primarily addresses particles. A purifier needs additional technologies, like an activated-carbon filter, to reduce some gaseous pollutants, and even then it cannot remove every pollutant completely.
For Delhi's pollution season, these two measures address different exposure issues. N95 masks help reduce inhalation of polluted particles while outdoors. Air purifiers help lower indoor concentrations of particulate matter. Using both can therefore provide greater protection than relying on either measure alone.
People with asthma, COPD, heart disease or other respiratory and cardiovascular conditions, as well as children and older adults, can be more vulnerable to the effects of air pollution.
Even healthy people can experience symptoms like coughing, throat irritation, wheezing, eye irritation and breathing discomfort when pollution levels rise.
New research suggests creatine may help older adults gain lean tissue and strength as they age.
Getting older changes what your body is made of. Fat tends to build up while muscle shrinks.
Now Texas A&M University researchers say creatine, a popular supplement, may help. In a 12-week study, adults aged 45 to 65 who took it gained lean tissue and strength, even without a structured exercise plan. But the study is small.
The paper appeared in the Journal of the International Society of Sports Nutrition in August 2026.

The researchers, led by principal investigator Richard Kreider, who directs Texas A&M's Exercise and Sport Nutrition Lab, said the 64 healthy adults finished the 12-week study. Each chose whether to join a supervised exercise and diet program. Then, within each group, they were randomly given either 10 grams of creatine a day or a placebo, a look-alike powder with no creatine. The participants did not knew which powder they were getting.
Among those who did not exercise, the creatine group gained about 2.4 pounds of lean tissue, the researchers said. They also got stronger in the leg press and bench press.
Those in the exercise program saw bigger gains with creatine than with a placebo in leg press, bench press and time to exhaustion, which is how long they could keep going before having to stop. Aerobic capacity did not seem to improve.
Losing weight often means losing muscle too. In the exercise group, people ate a diet with a small calorie cut. After 12 weeks, those on creatine had gained nearly three pounds of lean tissue and lost fat, the researchers said.
Those on a placebo showed little change in lean tissue. The researchers say creatine also cut body fat percentage more, which they believe is a first.
Creatine is a chemical compound found naturally in the body and in several foods including meat, fish, and protein-rich plant-based sources like tofu, tempeh, beans, lentils, and nuts.
Despite its natural occurrence and widespread use, especially among fitness enthusiasts, there is a growing body of evidence casting doubt on its effectiveness when used as a standalone enhancer for muscle growth.
Only 64 people finished the study. The researchers cautioned that because people chose their own exercise group, the groups may have differed in other ways. The study used 10 grams a day, while the paper describes 3 to 5 grams as a common long-term dose. Kreider says many people do not get enough creatine from food, according to Texas A&M. He says you would need five to 10 pounds of meat or fish a day to reach 10 grams.
So the takeaway is simple. Creatine looks promising for holding on to lean tissue with age, but one small study is not the last word.
