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.

Recent photographs of former US President Donald Trump with the UK’s King Charles III have drawn attention after visible discoloration was observed on his left hand, raising fresh questions about his health.
While Trump’s right hand has appeared discolored in earlier public appearances—a concern previously downplayed by both the former president and the White House—the latest images show similar changes on his left hand as well.
“Trump's right hand has been in bad shape for a long time now, but this picture taken today shows discoloration on the back of his left hand," independent journalist Aaron Rupar wrote on social media platform X.
Speaking to HealthandMe, Dr. Amit Prakash Singh, Consultant - Internal Medicine at the CK Birla Hospital, Delhi, explained the possible underlying causes that can result in hand discoloration. He noted that the condition may be due to:
This appears as blue, purple, or black patches. It may occur due to minor trauma or sometimes even spontaneously. The use of blood thinners or antiplatelet agents like aspirin can increase the likelihood of bruising. With age, blood vessels become more fragile, making bruising more common.
Dr. Singh advised people "to be concerned if there is sudden swelling in one hand, severe pain or tightness, persistent blue or black discoloration, breathlessness, fever with redness and warmth, or numbness and weakness".
"A purple or blue patch often suggests bruising, blue fingers may indicate circulation or oxygen issues, puffy hands suggest fluid retention, and red, hot swelling points toward infection," the expert said.
However, there is no official medical update on the discoloration in Trump's left hand. Therefore, any claims remain speculative. But it is not the first time that various speculations have been going around about the health of Trump.

In an interview with The Wall Street Journal, in January this year, the US President informed that he takes aspirin doses more than his doctors recommend, and that is the reason for the bruising seen on his right hand. He has repeatedly said that his health is in "excellent" condition.
In the interview, he said, "They say aspirin is good for thinning out the blood, and I don't want thick blood pouring through my heart."
Trump, now 70, was diagnosed with chronic venous insufficiency, a condition that occurs when veins have trouble moving blood back to the heart. He also showed signs of bruising on his hand, which many attributed to frequent handshaking and to the use of aspirin.
Aspirin may still be considered for some people under 60 or 70 who have a higher risk of heart disease, but this decision should be made carefully. Factors like high blood pressure, high cholesterol, diabetes, smoking history, or a strong family history can influence whether aspirin makes sense for an individual.

With temperatures rising sharply, experts at the All India Institute of Medical Sciences (AIIMS) have warned that young children are significantly more vulnerable to heat stress than adults, urging parents to take preventive measures and recognize early warning signs.
Despite morning showers offering some relief, the national capital still recorded temperatures close to 40°C.
Shefali Gulati, Professor, Department of Pediatric Neurology at AIIMS, highlighted that children are predisposed to both heat and cold stress and also tend to get dehydrated more quickly. She noted that global temperatures have been rising over the past few decades, and cited 2020 data from UNICEF, which showed that 76 per cent of children under 18 in South Asia—around 460 million—are exposed to extremely high temperatures, with 83 or more days in a year exceeding 35°C.
Dr. Gulati explained that young children often exhibit early behavioral changes when affected by heat. These can include irritability,
She added that heat exposure, when combined with air pollution, can worsen health conditions, particularly in children with lung diseases and asthma.
“Heat can affect all parts of the human body. It begins with irritability and can progress to exhaustion,” she said.
In more severe cases, heat stress may lead to brain exhaustion, loss of consciousness, seizures, dehydration, and electrolyte imbalance.
Dr. Gulati further explained that the human body maintains its core temperature through physiological mechanisms, but these are less efficient in young children. During dehydration, increased blood flow to the skin reduces supply to vital organs like the brain. In patients with pre-existing kidney issues, this can result in acute or chronic injury.
Children with conditions such as cerebral palsy and other neurological disorders may also experience worsening symptoms due to heat exposure.
Further, dehydration can additionally strain the cardiovascular system, thickening blood and leading to tachycardia, thereby affecting cardiac function.
Beyond children, pregnant women exposed to extreme heat may face risks such as preterm birth, neurodevelopmental problems, and cognitive issues in newborns.
Dr Gulati emphasized the importance of fluids, Oral Rehydration Solution (ORS), and small, frequent meals, along with reduced outdoor activity. Preventive measures include wearing loose clothing, avoiding direct sun exposure, and limiting outdoor activities during peak heat hours.

Parmeet Kaur, Chief Dietitian at AIIMS reiterated the importance of proper hydration, food safety, and dietary habits during extreme heat, warning that both children and adults face increased risk of dehydration and related complications.
“One has to avoid consuming extra sugary and salty foods, drinks, and snacks, because if one is consuming highly processed drinks or snacks loaded with sodium and sugar, it may lead to dehydration,” Kaur said.
"Hydration is key, and one should not wait to feel thirsty," she added, stressing the need to consume home-made and simple food.
For immediate management, homemade Oral Rehydration Solution (ORS) can be used, prepared with six teaspoons of sugar and half a teaspoon of salt in one liter of water.
However, she cautioned "against sugary drinks and packaged snacks like chips, explaining that high sugar and sodium content can worsen dehydration while giving a false sense of energy. While these products may create the impression of quick rehydration or an instant energy boost, they can instead contribute to greater fluid loss and increase the risk of severe dehydration.”
Instead, the expert recommended traditional cooling options such as bael sharbat, lassi, sattu, and gond katira. Ingredients like coriander, mint and onion were also suggested as part of summer dietary practices.
The dietician advised small, frequent meals that are easy to digest, including roasted and unsalted chana or peanuts, while avoiding heavy meals.
Food safety is another major concern during the summer. High temperatures increase the risk of microbial growth in stale or improperly stored food.
Kaur warned to "not consume food left at room temperature for more than two hours", as it can lead to microbiological growth. Sprouts were also flagged as potentially risky in hot weather.
Further, the expert also urged for "high heat cooking method with vegetarian food to be cooked at around 70°C, while non-vegetarian items require temperatures between 70°C and 80°C".

Even as heatwave conditions continue to intensify across parts of the country, cases of heat-related illnesses are on the rise, leaving many confused between heat stroke and heat exhaustion.
While both are caused by prolonged exposure to high temperatures, their severity, warning signs, and management can differ significantly.
Speaking to HealthandMe, Dr. Naval Vikram, Professor, Department of Medicine, at the AII India Institute of Medical Sciences (AIIMS), explained the key symptoms to watch out for, how to tell the difference between the two conditions, and the simple yet crucial steps individuals can take to protect themselves during extreme heat.
“The general features of a patient with heat stroke are: first, his or her body temperature will be very high. It will not be around normal levels like 104, 105, or 106—it will be significantly elevated. Second, the person may be delirious, confused, or even in a state of unconsciousness or coma. The breathing will also be labored. These are the features of heat stroke,” Dr Vikram said.
On the other hand, a person with heat exhaustion remains conscious, but looks and feels very tired. The individual is also likely to experience
"If this has happened after exposure to heat, it is similar to the feeling one gets after jogging, running, or playing for about half an hour and then feeling exhausted. If that same feeling occurs without doing any such activity, then it is a stage of heat exhaustion, because it is happening due to the heat,” Dr Vikram told HealthandMe.

The most vulnerable category for heat-related problems is the extremes of age—the younger children and older adults.
The expert noted that younger children may not be able to express their symptoms completely. They may not be able to tell you exactly what they are feeling.
At the other end, older adults often have multiple health issues—neurological conditions, diabetes, hypertension, and kidney problems.
"So multiple organs may already be affected to some extent. In such situations, if heat-related illness occurs, it becomes difficult to diagnose, especially if they already have neurological problems like confusion or altered behavior," Dr Vikram said.
With existing comorbidities, other organs may already be compromised, so the tipping point towards severity happens very quickly. In contrast, younger individuals generally have greater body reserves.
Therefore, people at the extremes of age are more vulnerable, also because it can sometimes be difficult to recognize and diagnose the condition in them.
While it may be impossible to avoid rising temperatures, the focus should be on how much you can protect yourself. The expert suggested measures such as:
