Visceral fat: the hidden health risk you need to know about

In a world preoccupied with body image, there lies a silent villain: visceral fat. Unlike the soft fat you can pinch beneath your skin, this dangerous type of fat lurks deep within your abdomen, wrapping itself around essential organs such as your liver, pancreas, and intestines. The potential health implications are alarming, but this hidden threat can be mitigated with simple lifestyle changes.

“Visceral fat is a silent health threat,” states Murray Hewlett, CEO of health cover provider Affinity Health. “You might appear healthy on the outside, but still have too much internal fat, putting pressure on your organs. It’s linked to some of the most serious conditions, from heart disease and diabetes to stroke and even certain cancers. The good news is that, with lifestyle changes, it can be reduced.”

Understanding visceral fat: what it is and why it matters

Your body stores fat in two primary forms: subcutaneous fat and visceral fat. The former, often referred to as the “pinchable fat”, accumulates just beneath the skin, while the latter, often deemed the more nefarious of the two, lives deep within the abdominal cavity.

Research from Harvard Health has shed light on the dangers of excess visceral fat. It is not merely a storage depot; it acts like an endocrine organ, producing harmful hormones and inflammatory molecules. High levels of visceral fat can lead to:

• Insulin resistance: Fatty acids and cytokines released from visceral fat disrupt insulin's ability to regulate blood sugar, raising the risk for diabetes.
• Chronic inflammation: This fat contributes to low-grade inflammation, which is associated with heart disease, stroke, and certain cancers.
• Liver strain: It can lead to conditions like non-alcoholic fatty liver disease, impacting how the body processes fats and sugars.
• Hormonal disruption: Visceral fat alters hormones that regulate appetite, mood, and metabolism.

Signs you may have excessive visceral fat

Though visceral fat is not directly visible, you can estimate its levels through various measurements:

• Waist circumference: A waist size over 94 cm for men or 80 cm for women can be indicative of excess visceral fat.
• Body shape: "Apple-shaped" bodies, which carry more weight around the midsection, are often associated with higher levels of visceral fat.
• Imaging scans: While not usually necessary, CT or MRI scans can accurately measure visceral fat if medical concerns arise.

What causes visceral fat to accumulate?

Several factors contribute to the unhealthy build-up of visceral fat, including lifestyle choices and genetics:

• Poor diet: A high intake of processed foods and added sugars promotes fat storage around organs.
• Physical inactivity: A sedentary lifestyle slows metabolism and reduces calorie burn.
• Chronic stress: Elevated cortisol from stress leads to increased abdominal fat storage.
• Lack of sleep: Short sleep duration is linked to an increase in visceral fat.
• Age and hormones: Aging naturally reduces muscle mass and metabolic rate, while hormonal shifts during menopause can significantly affect belly fat distribution.

Steps to safely reduce visceral fat

Despite the potential risks, the journey to reducing visceral fat is achievable through simple, sustainable lifestyle changes:

1. Focus on nutrition, not restriction: Transition to a balanced diet rich in whole foods — vegetables, fruits, whole grains, and lean proteins — while limiting unhealthy fats and sugars.
2. Reduce alcohol intake: Excess alcohol contributes to abdominal fat. Moderation is key.
3. Get moving every day: Regular aerobic exercise, strength training, and high-intensity interval training (HIIT) can significantly help reduce visceral fat.
4. Manage stress levels: Incorporate mindfulness practices, yoga, or regular walks to lessen the impact of stress on your body.
5. Prioritise sleep: Aim for 7–9 hours of quality sleep every night to help regulate cravings and metabolism.
6. Stay consistent: Changes may take time, but even a modest weight loss (5–10%) can result in significant health benefits.

The bottom line

Visceral fat is more than just an aesthetic concern; it poses a serious health risk to your overall well-being. Fortunately, it responds swiftly to healthy lifestyle changes, offering quick victories on the road to better health.
