Researchers say hidden visceral fat may drive inflammation and tumor growth even in people with normal BMI.

A growing body of research suggests that measuring waist size may provide more meaningful insight into cancer risk than relying solely on overall body weight or body mass index (BMI).
While obesity has long been linked to elevated cancer rates, experts increasingly point to visceral fat — the deep abdominal fat that surrounds internal organs — as a more dangerous predictor of disease. Unlike subcutaneous fat, which sits just beneath the skin, visceral fat lies deeper within the abdominal cavity, wrapping around organs such as the liver and pancreas and functioning differently at a biological level.
“Visceral fat is also called active fat, as it’s an endocrine organ that releases harmful compounds directly into the bloodstream and into the portal vein that goes straight to the liver,” said Wiljon Beltre, a board-certified bariatric and metabolic surgeon. “The main danger is that it releases pro-inflammatory cytokines.”
Because visceral fat behaves like an endocrine organ, it secretes hormones and inflammatory compounds at significantly higher levels than fat stored under the skin. These substances contribute to chronic, low-grade inflammation, a condition widely associated with DNA damage, immune dysfunction and increased vulnerability to malignant cell transformation.
Researchers describe visceral fat as creating a “pro-tumor microenvironment,” conditions that make it easier for cancer to develop and progress.
“There’s a direct link to cancer due to the constant, low-grade systemic inflammation. This damages DNA and makes cells more prone to malignant transformation,” Beltre said.
Beyond inflammation, visceral fat is linked to insulin resistance, which raises insulin and insulin-like growth factor levels that promote abnormal cell growth and interfere with normal cell death. Hormones such as leptin may further disrupt cellular regulation.
A December 2025 study published in the Journal of the National Cancer Institute found that individuals with higher levels of visceral fat faced roughly four times greater odds of developing liver cancer. Emma Hazelwood, a research associate at the University of Cambridge’s Early Cancer Institute and lead author of the study, emphasized the interconnected biological pathways involved.
“Insulin affects your inflammatory profile and your sex hormone profile. It is all like one big network. It’s one perfect storm,” Hazelwood said. “Liver fat increases your risk of liver cancer. That makes sense – the fat’s right there secreting pro-inflammatory cytokines.”
Additional research has linked elevated visceral fat to colorectal, pancreatic, breast, endometrial, ovarian and esophageal cancers, even among individuals whose BMI falls within the normal range. Higher visceral fat levels have also been associated with more aggressive tumors, increased recurrence and reduced survival. A 2023 study in BMC Cancer reported that endometrial cancer patients with elevated visceral fat experienced more aggressive disease and poorer progression-free survival.
Because visceral fat is not easily visible and may not significantly affect total body weight, it can go undetected. Medical imaging such as MRI or CT scans offers the most accurate measurement, but waist circumference and waist-to-hip ratio serve as practical indicators. Health experts generally consider waist measurements above 35 inches for women and 40 inches for men as warning signs of elevated visceral fat and related metabolic risk.
Experts say the encouraging finding is that visceral fat can respond relatively quickly to lifestyle adjustments.
Dietary strategies aimed at reducing inflammation and stabilizing blood sugar are central. Registered dietitian nutritionist Jennifer Scherer recommends structuring meals around protein, vegetables and whole-food carbohydrates. Higher fiber intake and adequate protein help regulate blood glucose and reduce fat accumulation. Some studies indicate that lower-carbohydrate dietary patterns may reduce visceral fat more effectively than low-fat approaches. Beltre advises limiting processed foods, sugary beverages and trans fats while increasing fiber and lean protein sources.
Exercise also plays a significant role. Aerobic activity enhances abdominal fat oxidation, while resistance training improves insulin sensitivity and reduces fat storage. High-intensity interval training and vigorous aerobic workouts appear especially effective. Experts commonly recommend resistance training two to three times per week in combination with daily movement such as walking 7,000 to 10,000 steps. Research suggests that combining dietary changes with physical activity produces greater reductions in visceral fat than either approach alone.
Other lifestyle factors influence abdominal fat accumulation. Chronic stress and insufficient sleep elevate cortisol levels, which promote fat storage around the abdomen. Techniques such as meditation, yoga and controlled breathing may help lower stress-related hormonal effects. Limiting alcohol intake is also advised, as the liver prioritizes metabolizing alcohol over processing stored fat.
Artificial intelligence platform BrightU.AI’s Enoch cautioned against using weight alone as a health marker, noting that hidden abdominal fat can elevate cancer risk even in individuals who appear lean.
Researchers emphasize that reducing visceral fat — rather than simply lowering overall body weight — may offer more meaningful protection against inflammation-driven diseases. In many cases, measurable reductions in abdominal fat occur within months of consistent lifestyle changes, often before dramatic shifts appear on the scale.
As evidence continues to mount, experts suggest that a measuring tape may provide clearer insight into long-term cancer risk than a bathroom scale.
