Traditional guidance has been to eat three square meals a day — but a trending diet plan has some people eating just once.

Dubbed the One Meal a Day (OMAD) diet, it’s a form of intermittent fasting that involves eating all the day’s calories in a single meal, after 23 hours of fasting. 

Dr. Jason Fung, a Canadian nephrologist (kidney specialist), is known to be an expert in intermittent fasting (IF). He spoke with Fox News Digital about the OMAD diet, which he described as a stricter version of IF.

Both diets involve “time-restricted eating,” Fung noted — but with intermittent fasting, people can eat twice a day.

If you only eat once a day, the natural tendency will be to eat less overall, he said.

The body is either in a state of storing calories or burning them, according to the expert.

When a person fasts for an extended period, the body begins to use fat for energy, which can actually decrease hunger, Fung said.  

Who could benefit?

The two main health conditions that can greatly benefit from OMAD and intermittent fasting are weight loss and type 2 diabetes, according to Fung.

“Fasting really impacts weight and sugars, because that’s the way calories are stored – as sugar and fat,” he said.

Losing weight can potentially reduce the risk of heart disease, stroke and obesity-related cancers, the doctor noted, in addition to alleviating back pain, knee pain and pressure on joints.

“You can actually reverse your type 2 diabetes with intermittent fasting,” Fung said, referencing previously studies published by the National Institutes of Health and Diabetes Care.

Fung described how one of his patients who had diabetes for 15 years was able to discontinue his insulin medication after going on the OMAD diet three times a week for a month.

The patient is still not taking insulin and continues to fast regularly, though not as frequently, he added.

“You can actually reverse your type 2 diabetes with intermittent fasting.”

People with hypoglycemia who are not on blood glucose-lowering type 2 diabetes medications should still be able to follow the OMAD diet if they avoid highly refined carbohydrates, which can cause glucose levels to spike, said Fung.

He recommends eating whole, natural, unprocessed foods.

Fern Katzman, a Toronto-based clinical nutritionist, told Fox News Digital that she has seen patients with type 2 diabetes go off Metformin, an oral antidiabetic medication, or not have to go on it at all after engaging in intermittent fasting, or OMAD.

Katzman said people should have a reason to go on OMAD, such as to address medical issues or to bring down elevated blood sugar levels after a period of eating or drinking excessively.

“Insulin drives cravings,” she told Fox News Digital. “After you eat or drink a lot, your insulin spikes, and that makes you hungry.”

Katzman added, “The one thing that everybody tells me when they’ve done OMAD is that the cravings stop — and that is the key to any weight loss program.”

In addition to losing weight, Katzman said her patients have reported better digestion and decreased bloating on the OMAD diet because “sugar makes yeast and yeast bloats you.” 

Patients have also noticed immediate improvements in their mood and energy levels on the diet, she added.

Katzman recommends filling up on vegetables, protein and grains, like quinoa and small amounts of brown rice.

‘Not for everyone’

Katzman cautioned that OMAD is “not for everyone” — it’s likely not a good choice for those who have eating disorders or are hypoglycemic, for example.

Dr. Lisa Young, a registered dietitian nutritionist in Florida, echoed those same concerns, warning that the OMAD diet can trigger people with eating disorders.

“You’re not focusing on your intuitive internal signals of hunger and fullness,” she told Fox News Digital. “You’re not trusting yourself.”

For those following the diet, experts recommend sticking to “whole, natural, unprocessed foods.” (iStock)

Young also warned that the diet can “make you fatigued.”

“It could even make you hungrier and cause hypoglycemia (low blood sugar),” she added.

Dr. Joel Kahn, a holistic cardiologist in Michigan, is also not a proponent of the OMAD diet.

The doctor noted that studies from the National Institutes of Health and the Journal of the American Medical Association (JAMA) substantiate that eating just one meal in the evening can result in declining metabolic health, higher blood sugar levels and greater insulin resistance.

“You’re not focusing on your intuitive internal signals of hunger and fullness.”

“Theoretically, if you’re going to do a One Meal a Day diet, you might actually do it in the morning hours,” Kahn told Fox News Digital.

The doctor instead recommends the Daniel Diet, which he described as a “faith-based diet” of plants and legumes inspired by the Book of Daniel.

Khan is also a fan of the Prolon 5-Day Program, a plant-based fasting-mimicking diet, which he said could help people achieve a younger biological age.

Actor and Grammy winner Jamie Foxx opened up about a medical emergency that was nearly fatal.

In his Netflix comedy special, “Jamie Foxx: What Had Happened Was,” Foxx revealed that he suffered a brain bleed in April 2023 that put him into a coma for several weeks.

“I was fighting for my life,” Foxx said. “April 11, I was having a bad headache, and I asked my boy for an aspirin … before I could get the aspirin … I went out. I don’t remember 20 days.”

Foxx received surgery to respond to the brain bleed that led to a stroke. 

Foxx’s doctor at Piedmont Hospital reportedly declared, “If I don’t go in his head right now, we’re going to lose him.”

“On May 4, I woke up. When I woke up, I found myself in a wheelchair. I couldn’t walk,” Foxx went on.

In time, and with the help of his family and faith, Foxx slowly recovered in what he considered to be a “miracle.”

Three months after he privately battled his “medical complication,” the actor spoke out about the matter in a video he posted to Instagram, in which he admitted he went to “hell and back.”

What is a brain bleed?

Foxx’s experience was no joke, according to Dr. Paul Saphier, M.D., a neurosurgeon and founder of Coaxial Neurosurgical Specialists in New Jersey.

In a conversation with Fox News Digital, Saphier shared the dangers of brain bleeds, or hemorrhagic stroke, which account for 10% to 15% of all strokes.

The condition affects approximately 70,000 to 80,000 U.S. patients per year.

A brain bleed causes blood to pool between the brain and skull, which prevents oxygen from reaching the brain, according to Cleveland Clinic.

A brain bleed, or hemorrhagic stroke, can occur for a variety of reasons and can be deadly.  (iStock)

The first symptom of a brain bleed is a sudden, severe headache, but can also include nausea and vomiting, confusion, dizziness, slurred speech, sleepiness and lack of energy.

Some potential causes of a brain bleed include head trauma, blood clots, a weak spot in a blood vessel, a brain tumor and other abnormal occurrences, per Cleveland Clinic.

They can also occur due to issues related to high blood pressure, high cholesterol, diabetes, smoking, alcohol abuse and age, Saphier stated.

“These bleeds can also be related to blood vessel issues, such as brain aneurysms and vascular malformations,” he added.

As brain bleeds and heart health go hand in hand, Saphier promotes heart-healthy living as a way to decrease risk.

“For patients with a strong family history of intracranial hemorrhages, the American Heart [Association] and American Stroke Association recommend screening for brain aneurysms and vascular malformations for early detection and prevention,” the doctor noted.

Quick treatment is essential

Nearly 45% of patients with a “spontaneous intracerebral hemorrhage,” or brain bleeding, do not survive, according to Saphier.

About two-thirds of these survivors reportedly do not return to their “pre-hemorrhagic stroke baseline.”

If a brain bleed is not treated quickly, it can lead to permanent damage, including memory loss, difficulty swallowing and speaking, coordination challenges, numbness or weakness in body parts, vision loss, and emotional changes, Cleveland Clinic states.

“Any type of lifestyle activities that are considered heart-healthy are also healthy for the brain and its blood vessels,” a doctor noted. (iStock)

To reduce the risk of brain bleeding, Cleveland Clinic recommends managing blood pressure, lowering cholesterol levels, maintaining a healthy weight, limiting alcohol consumption, stopping smoking, eating a balanced diet and exercising regularly.

“A general principle that I tell my patients is that any type of lifestyle activities that are considered heart-healthy are also healthy for the brain and its blood vessels,” Saphier advised.

“If someone does have a strong family history of brain aneurysms, or [intracranial] hemorrhages, they should discuss [it] with a primary care doctor, as they may be a candidate for brain aneurysm screening and prevention,” he added.

Hundreds of deadly virus samples are missing from a laboratory in Australia, the Queensland government announced on Monday.

The government has instructed Queensland Health — Australia’s public health department — to launch an investigation into what’s being described as a “major historical breach of biosecurity protocols,” according to the online media statement.

It was reported that 323 vials of multiple infectious viruses — including Hendra virus, Lyssavirus and Hantavirus — went missing from Queensland’s Public Health Virology Laboratory in August 2023.

‘DISEASE X’ HAS KILLED DOZENS IN THE CONGO — HERE’S WHAT TO KNOW ABOUT THE MYSTERY ILLNESS

Hendra is a zoonotic (animal-to-human) virus that has only been found in Australia. 

Hantavirus is a family of viruses that can lead to serious illness and death, according to the Centers for Disease Control and Prevention, while Lyssavirus is a group of viruses that can cause rabies.

The lab where the samples went missing provides “diagnostic services, surveillance and research for viruses and mosquito and tick-borne pathogens of medical importance,” the release stated.  

It is not known whether the infectious samples were stolen or destroyed, the statement said, and there is “no evidence of risk to the community.”

The government has launched a “Part 9 investigation.”

“With such a serious breach of biosecurity protocols and infectious virus samples potentially missing, Queensland Health must investigate what occurred and how to prevent it from happening again,” Minister Timothy Nicholls said in the release.

“The Part 9 investigation will ensure nothing has been overlooked in responding to this incident and examine the current policies and procedures in operation today at the laboratory.”

“This investigation will also consider regulatory compliance and staff conduct.”

Nicholls added that Queensland Health has taken “proactive measures,” including retraining staff on required regulations and conducting audits to ensure correct storage of materials.

Sam Scarpino, PhD, director of AI and life sciences at Northeastern University in Boston, confirmed that the situation in Australia amounts to a “critical biosecurity lapse.” 

“Given the limited ability for any of these pathogens to transmit from person to person, the risk of an epidemic is very low.”

“The pathogens reported missing are all high-consequence and could pose a threat to the public,” he told Fox News Digital. 

The three pathogens can have very high fatality rates in humans, Scarpino said, but they do not transmit readily from person to person.

“Some hantaviruses have case fatality rates of up to 15%, or over 100 times more lethal than COVID-19, while others are more similar to COVID-19 in terms of severity,” he said. 

There is also a high risk to animals and livestock from all three pathogens, he added. 

FIRST KNOWN CASE OF RARE MPOX STRAIN CONFIRMED IN UNITED STATES

The Lyssavirus family contains the rabies virus, which is almost universally fatal in humans if they do not receive treatment in time, the expert noted. 

“Given the limited ability for any of these pathogens to transmit from person to person, the risk of an epidemic is very low,” Scarpino said. 

“It’s clear that we need quite a bit more investment and transparency related to pathogen biosecurity,” one expert said. (iStock)

“However, Hendra virus — along with certain members of the Hantavirus and Lyssavirus family — can be very severe in humans and animals.”

Chief Health Officer Dr. John Gerrard reiterated in the media statement that there is no evidence of public risk.

“It’s important to note that virus samples would degrade very rapidly outside a low temperature freezer and become non-infectious,” he said.

“It’s very unlikely that samples were discarded in general waste, as this would be completely outside routine laboratory practice.”

Hantavirus is a family of viruses that can lead to serious illness and death, according to the Centers for Disease Control and Prevention. (iStock)

There have been no human cases of Hendra or Lyssavirus in Queensland over the past five years, Gerrard noted, and no confirmed Hantavirus infections “ever in Australia.”

Despite the low risk, Scarpino said, “It’s important to understand where these samples ended up, to confirm that there is no longer a risk of exposure.”

“While I applaud the Australian government for taking this seriously, it’s unacceptable that it took over a year for news of the breach to be made public.”

“The pathogens reported missing are all high-consequence.”

There have been similarly high-profile biosecurity lapses in the U.S., Scarpino noted.

“It’s clear that we need quite a bit more investment and transparency related to pathogen biosecurity,” he added.

Fox News Digital reached out to the Queensland government requesting further comment.

Fentanyl has made headlines for driving overdose deaths, but the Centers for Disease Control and Prevention (CDC) is warning of the rise of an even deadlier drug.

Last year, nearly 70% of all U.S. overdose deaths were attributed to illegally manufactured fentanyls (IMFs). One of those was carfentanil, an altered version of fentanyl that is said to be 100 times more potent, the CDC warned in a Dec. 5 alert.

Deaths from carfentanil rose by more than 700% in the past year, according to the same source — there were 29 deadly overdoses between January and June 2023, and 238 in that same time frame in 2024.

RED FOOD DYE COULD SOON BE BANNED AS FDA REVIEWS PETITION: ‘SCARY STUFF’

This data came from the CDC’s State Unintentional Drug Overdose Reporting System (SUDORS).

The numbers could actually be higher, as the 2024 data is preliminary and not all overdose deaths have been reported, the agency noted.

Since an outbreak of carfentanil-linked deaths in 2016 and 2016, the drug had “largely disappeared” until this recent reemergence, the CDC noted.

Based on the increase in fatal overdoses, the CDC is calling for “rigorous monitoring” of carfentanil and other opioids more potent than fentanyl.

DRUG OVERDOSES HAVE REACHED RECORD HIGH, PER LATEST CDC REPORT: ‘GRIM STATISTICS’

As with other illicit drugs, its “high profitability” likely drives its prevalence, according to Dr. Chris Tuell, clinical director of addiction services at the University of Cincinnati College of Medicine.

“Very small amounts can produce thousands of doses,” he told Fox News Digital.  

“Synthetic opioids like carfentanil are relatively easy to manufacture in illicit labs,” Tuell went on. “Since the drug is a synthetic, it is easier to produce — unlike heroin, which is dependent on a plant like opium.”

Why is carfentanil so dangerous?

Carfentanil is 10,000 more times more potent than morphine and 100 times more potent than fentanyl, Tuell confirmed.

“Even a small amount can be fatal, as it can cause respiratory failure,” he said.

Carfentanil can sometimes be in the form of “pressed pills” that resemble prescription medications, the expert said. (iStock)

One of the major concerns with carfentanil and fentanyl is that they are frequently mixed with other drugs, such as benzodiazepines, cocaine and opioids, which can lead to accidental overdoses, according to Tuell.

“Carfentanil can also resemble cocaine and heroin, so it blends right in with the other drugs,” he warned.  

“Even a small amount can be fatal, as it can cause respiratory failure.”

“Even a tiny amount can increase the potency of a drug mixture, leading to a stronger and longer-lasting high.”

Carfentanil often appeals to drug users who have a high tolerance to opioids because they seek a stronger substance, “making the drug attractive despite the risk,” Tuell noted.

How is the drug administered?

Carfentanil can be injected and is frequently mixed with other opioids or heroin, Tuell said. In a powder form, it can be inhaled.  

“Inhaling the drug can be quickly risky because it can enter the bloodstream, resulting in an overdose,” Tuell warned. “This can happen intentionally or accidentally, as the drug can become easily airborne.”

Carfentanil can sometimes be in the form of “pressed pills” that resemble prescription medications, the expert said.

“Carfentanil can be lethal at the 2-milligram range depending on the route of administration,” he cautioned.

What parents should know

“Children are now the generation of artificial intelligence and deepfakes, as illicit drugs are posing like regular prescription medications,” Tuell cautioned.

To help protect kids from the dangers of illicit drugs, the expert emphasized the importance of open communication and education.

“Educate your child about the dangers and risks of drug use, including synthetic opioids like carfentanil,” he advised.

Parents should provide monitoring and supervision of their children, be aware of their social circles and limit unsupervised online activities, Tuell recommended.

“I also believe it is important that parents realize that 84% of individuals with a substance use disorder also have a co-occurring mental health issue,” he added. 

“Seeking out mental health services for your child could help address the underlying issues that may have led to a substance use disorder.”

The CDC called for specific efforts in preventing deaths from illegally manufactured fentanyls, “such as maintaining and improving distribution of risk reduction tools, increasing access to and retention of treatment for substance use disorders, and preventing drug use initiation.”
