People with “beer bellies” may have an increased risk of heart damage, raising fresh concerns about the health risks tied to extra weight around the midsection.

German researchers found that men with fat deposits around the abdomen showed clear signs of early heart damage, even when their overall weight wasn’t especially high.

Scientists wanted to better understand whether abdominal fat — the kind stored deep around internal organs — is more harmful to the heart than general body fat.

Doctors have long suspected that fat distribution, not just total pounds, plays a major role in heart disease. This study tested that idea using cardiac MRI scans.

“Abdominal obesity, a high waist-to-hip ratio, is associated with more concerning cardiac remodeling patterns than high body mass index (BMI) alone,” said study lead author Jennifer Erley, M.D., radiology resident at University Medical Center Hamburg-Eppendorf, Germany, in a press release.

The research team examined 2,244 adults between the ages of 46 and 78, none of whom had been diagnosed with heart disease. Each participant underwent high-resolution MRI scans that measured the size, thickness and volume of the heart’s chambers.

Researchers also collected detailed health information, including weight, blood pressure, cholesterol, smoking status and diabetes history.

RESEARCHERS SAY BEING ‘FAT BUT FIT’ COULD BE LESS DEADLY THAN BEING UNDERWEIGHT

Instead of relying solely on BMI, which can miss where fat is stored, the team used a measurement of waist-to-hip ratio, which compares the circumference of the waist to the hips and determines how much fat sits around the abdomen. 

High ratios point to visceral fat, which is the deeper, metabolically active fat linked to inflammation and organ stress.

MEN MAY NEED TO WORK TWICE AS HARD AS WOMEN TO PREVENT POTENTIALLY DEADLY DISEASE

Men with higher waist-to-hip ratios showed a pattern of thicker heart muscles and smaller internal chamber volume. That means the heart muscle becomes bulkier but holds less blood, forcing it to work harder, according to the researchers.

“[Abdominal obesity] appears to lead to a potentially pathological form of cardiac remodeling,” said Erley.

Based on BMI alone, 69% of males and 56% of females in the study were overweight or obese. Using waist-to-hip ratio, however, 91% of the males and 64% of females met the criteria for obesity.

General obesity based on BMI was more often linked to enlarged heart chambers for all participants. Abdominal obesity was associated with thickening of the heart muscle and smaller heart chamber volumes.

Over time, those structural changes can lead to heart failure or other cardiovascular problems, the researchers warned.

“[Abdominal obesity] appears to lead to a potentially pathological form of cardiac remodeling.”

These associations remained strong even after researchers accounted for age, smoking, blood pressure and other risk factors.

The same trend appeared in women, but the effect was significantly stronger in men. Researchers noted that men tend to store fat in the abdomen more readily than women, especially as they age, which may explain the sharper impact.

The findings help to clarify why some people with normal or moderately elevated BMI still develop heart disease, while others weighing more do not. It also suggests that simply stepping on a scale may not capture the full picture of heart risk.

The study did have some limitations, primarily that it was observational in design, meaning that it identified patterns but could not prove direct causation.

Additionally, researchers did not follow participants long enough to see who eventually developed heart disease, they acknowledged.

And waist-to-hip ratio, while useful, is a simplified measure that doesn’t capture all variations in body composition.

The findings are being presented this week at the annual meeting of the Radiological Society of North America in Chicago.

Scientists at UCLA have developed an “off-the-shelf” cell-based immunotherapy that was able to track down and kill pancreatic cancer cells even after they had spread to other organs.

In a mouse study, the treatment slowed cancer growth, extended survival and remained effective even within the harsh environment of solid tumors.

“Even when the cancer tries to evade one attack pathway by changing its molecular signature, our therapy is hitting it from multiple other angles at the same time. The tumor simply can’t adapt fast enough,” lead author Dr. Yanruide Li, a post-doctoral scholar at UCLA, said in a press release.

CANCER SURVIVAL APPEARS TO DOUBLE WITH COMMON VACCINE, RESEARCHERS SAY

To build the therapy, researchers took human stem cells and turned them into a special type of immune cell called an invariant natural killer T cell (or NKT cell).

Next, they genetically modified those cells by adding a CAR receptor (chimeric antigen receptor), which enables the cells to recognize and attack pancreatic cancer cells.

NKT cells are naturally compatible with any immune system, which means they can enter the body without causing dangerous reactions, according to the researchers. They can also be mass-produced using any donated blood stem cells.

“One donor could provide sufficient cells for thousands of treatments,” potentially offering a more affordable and accessible approach, according to the press release.

The team tested the therapy in several lab models. These included models where the cancer was placed directly into the pancreas and others designed to mimic how the disease spreads to other organs, like the liver and lungs.

The CAR-NKT cells were able to push their way into the tumor itself, rather than getting stuck on the outside like many immune treatments do, the researchers found.

Once they got inside the body, these engineered immune cells could spot cancer cells in several different ways and kill them using multiple built-in attack methods.

Most importantly, they stayed active. Many immune cells that enter a solid tumor quickly become overwhelmed and shut down, but these engineered cells kept working instead of burning out, allowing them to continue fighting the cancer for a longer period.

The findings were published in the journal PNAS (Proceedings of the National Academy of Sciences).

“Developing a therapy that targets both the primary tumor and its metastases in pre-clinical studies — one that can be ready to use off-the-shelf — represents a fundamental shift in how we might treat this disease,” said senior author Dr. Lili Yang, a professor of microbiology, immunology and molecular genetics at UCLA, in the same press release.

The researchers noted that one dose could cost around $5,000, far lower than personalized CAR-T treatments.

Pancreatic cancer is notoriously aggressive and difficult to treat, according to the researchers. Most patients aren’t diagnosed until the disease has already spread, and the tumor’s biology creates multiple physical and chemical barriers that weaken the impact of traditional treatments.

Since the therapy targets a protein that is common in breast, ovarian and lung cancers, the same cell product could potentially treat multiple cancer types. 

In separate studies, the team has already demonstrated the therapy’s effectiveness against triple-negative breast cancer and ovarian cancer.

Based on the early findings, the UCLA researchers are preparing to submit applications to the Food and Drug Administration to begin human trials.

“We’ve developed a therapy that’s potent, safe, scalable and affordable,” Yang said in the release. “The next critical step is proving it can deliver the same results in patients we’ve seen in our preclinical work.”

All testing so far has been done in mice, as the researchers noted that solid tumors in humans are far more complex. Human tumors can evolve and lose the targets that treatments are designed to recognize, raising the risk of the cancer escaping detection and continuing to grow.

Long-term safety and side effects in humans are unknown ahead of clinical trials.

The researchers also noted that making big batches of identical, safe cells poses logistical and regulatory challenges.

Dick Van Dyke turns 100 this year, and he says he feels “really good.” 

In a recent conversation with People, he credits his attitude for both his age and the fact that he has “no pain, no discomfort.”

“I’ve always thought that anger is one thing that eats up a person’s insides – and hate,” Van Dyke said, explaining how people often ask what he did right.

He added that he’s “rather lazy” and never felt driven by the kind of resentment that can harden over time.

“Sometimes I have more energy than others – but I never wake up in a bad mood,” he told People.

The actor explained that while there were always things and people he didn’t like or approve of, he “never really was able to work up a feeling of hate,” and certainly not “a white-heat kind of hate.”

He contrasted himself with his father, who was “constantly upset by the state of things in his life,” noting to People that his father died at 73.

Van Dyke believes avoiding that emotional pattern is one of the chief things that kept him going.

“When you expire, you expire,” he told People. “I don’t have any fear of death for some reason. I can’t explain that but I don’t. I’ve had such a wonderfully full and exciting life… I can’t complain.”

Van Dyke’s 100th birthday falls on Dec. 13.
