Hidden Fat, Faster Hearts: Study Links Visceral Fat to Accelerated Cardiac Aging – But ThereS Hope
By Dr.Michael Lee, World-Today-News.com – August 26, 2025
(London) - Forget chronological age. Your heart may be aging faster than you think, and a new study published in the European Heart Journal points to a surprising culprit: visceral fat. This “hidden” fat, nestled deep within the abdomen surrounding vital organs, is now directly linked to accelerated cardiac aging, perhaps increasing the risk of heart disease – the world’s leading cause of death.
The groundbreaking research, spearheaded by scientists at the Medical Research council (MRC) Laboratory of Medical Sciences in London, analyzed data from over 21,000 participants in the UK Biobank, utilizing advanced artificial intelligence to assess cardiac health. Researchers weren’t just looking at weight; they were mapping where fat was stored and correlating that with detailed images of the heart and blood vessels, identifying signs of aging like stiffening and inflammation. Each participant received a “cardiac age” – a measure of their heart’s biological age – which was then compared to their actual age.
The results were stark. Higher levels of visceral adipose tissue - the fat surrounding the stomach, intestines, and liver – were consistently associated with a faster cardiac age. This is notable as, as the study authors point out, aging is the single biggest risk factor for heart disease, but the rate at which individuals age varies dramatically.
“we’ve long known visceral fat is detrimental to overall health,” explains Dr. Rishi calonji, lead researcher at the MRC and imperial College London, and a teacher of Cardiovascular AI at the British Heart Foundation. “But this study definitively links it to the aging process within the heart itself. And crucially, we’ve shown that BMI alone is a poor predictor of cardiac age – it’s not just how much fat you have, but where you have it.”
The Sexes Differ: Apple vs. Pear & The Power of Estrogen
The study also revealed captivating differences between men and women. The classic “apple” shape – fat concentrated around the belly – was particularly predictive of premature cardiac aging in men.Conversely, a genetic predisposition towards the “pear” shape – fat distributed around the hips and thighs – appeared to be protective against cardiac aging in women.
This protective effect in women is potentially linked to estrogen levels. Researchers observed that premenopausal women with higher estrogen levels exhibited a slower rate of cardiac aging, suggesting a hormonal role in safeguarding heart health.
“We’ve understood the ‘apple’ versus ‘pear’ body fat distinction for some time, but the mechanisms driving these health outcomes have been unclear,” Dr. Calonji elaborates. “Our research suggests that ‘bad’ fat, hidden deep around the organs, actively accelerates heart aging. The question now is, can we harness the protective qualities of ‘good’ fat, and estrogen, to develop targeted therapies?”
Inflammation: The missing Link
Further analysis revealed that visceral fat is associated with increased inflammation throughout the body, a known driver of aging and disease. This suggests that visceral fat isn’t just passively accumulating; it’s actively contributing to a systemic inflammatory response that damages the heart and blood vessels.
What Can You Do?
While the findings may seem daunting, experts emphasize that lifestyle changes can make a significant difference.
“A healthier diet and increased physical activity are key to reducing visceral fat levels,” says Professor Bryan Williams Obe, Scientific Director and Doctor at the British Heart Foundation. “Focus on reducing processed foods, increasing your intake of fruits, vegetables, and lean protein, and incorporating regular exercise into your routine.”
Looking ahead, Dr. Calonji’s team plans to investigate whether emerging drug therapies, such as GLP-1 receptor agonists (like Ozempic and Mounjaro), can not only improve metabolic health but also slow cardiac aging.
This research underscores a critical shift in how we assess heart health. It’s no longer enough to simply monitor weight and cholesterol. Understanding the distribution of body fat – and the underlying hormonal and inflammatory processes – is paramount to preventing heart disease and extending healthy lifespan.
Key Takeaways:
visceral fat accelerates cardiac aging: Fat hidden deep within the abdomen is directly linked to a faster biological age of the heart.
Sex differences matter: ”Apple” shape is riskier for men, while “pear” shape might potentially be protective for women.
Estrogen plays a role: Higher estrogen levels in premenopausal women are associated with slower cardiac aging.
Inflammation is a key driver: Visceral fat promotes systemic inflammation, damaging the heart.
Lifestyle changes are crucial: Diet and exercise can definitely help reduce visceral fat and protect heart health.
