Most people associate protein with gym culture — shakes, weights, muscle-building. But for anyone interested in healthy ageing, metabolic resilience, fat loss, and long-term independence, protein deserves far more attention. Adequate daily protein intake is one of the most powerful

Raised visceral fat quietly disrupts thyroid chemistry, increasing reverse T3 and lowering active T3 inside tissues. This pushes the body into metabolic “conservation mode” — slowing energy, mood and fat loss despite normal blood tests. Reducing VAT gradually restores healthy thyroid activation and metabolic resilience.

Adequate protein and resistance training are essential for healthy ageing and reducing visceral fat. As we grow older, muscles become less responsive, making higher protein intake vital to preserve strength, metabolism, and independence. Building and feeding muscle is the most effective way to improve insulin sensitivity, raise metabolic rate, and burn harmful VAT.

Patients often ask about home monitoring tools — ECG devices, blood pressure monitors, glucose apps. We now also encourage people to track their waistline and visceral fat, using body composition scales alongside more traditional equipment. To support this, I have created a page of recommended home gadgets that can help patients take greater ownership of their health — a vital step towards a more proactive, prevention-focused model of care, guided by their clinical and educat

The most effective path to reducing visceral fat without medication is not just to “eat less.” It’s to build more muscle, eat smarter, and track your progress. In this blog, which also forms one of the chapters of an ebook, I outline the programme and tools our patients use in our cardiometabolic clinic.

Traditional health improvement plans assume everyone responds the same way. Real life tells us otherwise. N-of-1 explains how to use a personalised, precision-medicine approach to reduce visceral fat, stabilise metabolism and rebuild long-term health. Through weekly reflections, practical tools and small self-experiments, the book guides you to uncover what truly works for you — not for the average patient, but for your own unique physiology.

At SCVC we use low dose CT to measure visceral adipose tissue (VAT). With a radiation dose of 1mSv – equivalent to 1/4 of the dose used in a mammogram. The test determines what proportion of an expanded waistline is visceral (metabolically dangerous) versus subcutaneous (metabolically benign) fat. When combined with other anthropometrics such as weight, height, waist we use AI to calculate a metabolically healthy target waist and weight to aim for. A example of a repeat scan

Some small studies show lower T3 inside fat tissue in people with obesity. This doesn’t mean systemic hypothyroidism — it simply suggests inflammation may reduce local T3 activation. Raised visceral fat quietly disrupts thyroid chemistry, increasing reverse T3 and lowering active T3 inside tissues.

Semaglutide’s cardiovascular benefits extend beyond weight loss — it powerfully reduces visceral adipose tissue (VAT), the internal fat that drives inflammation, insulin resistance and small dense LDL. At SCVC, our GLP-1 programme targets VAT directly using personalised VAT scans and flexible dosing to improve long-term heart health.

At Surrey Cardiovascular Clinic, we have seen a pattern: some people whose blood sugar (HbA₁c) is technically “normal” are quietly drifting towards diabetes. Their blood tests look fine — but their day-to-day glucose readings tell another story.

The keto and Atkins diets have profound effects on hepatic lipid metabolism, and hence on LDL cholesterol handling. Let’s unpack this carefully through the lens of the endogenous cholesterol pathway.

MASLD is a silent but important marker of metabolic health and another consequence of raised Visceral Adipose Tissue (VAT). Although often discovered by chance, it carries significant implications for both liver and cardiovascular wellbeing. Through caloric restriction, physical activity, improved nutrition, and early intervention, MASLD can usualy be stabilised or reversed — protecting not just the liver, but the heart as well.

Small dense LDL (sdLDL) is the most harmful form of “bad cholesterol.” It forms when the liver overproduces VLDL — often driven by visceral fat and high insulin levels. Visceral fat sits deep around the organs and feeds directly into the liver, causing early metabolic disruption long before blood tests detect it.

HIIT interrupts this cycle by dramatically improving insulin sensitivity and glucose uptake in skeletal muscle — particularly in the large lower-limb muscles of the thighs and glutes. A single 20-minute session of HIIT can activate GLUT-4 transporters in muscle cells for up to 24–48 hours, drawing glucose out of the bloodstream and away from storage in the liver and visceral fat depots.

At Surrey Cardiovascular Clinic, we move beyond detecting risk to delivering a tiered, personalised framework for metabolic and cardiovascular prevention. Using real-time tools like CGM, the DoctorShape app, imaging, and nurse-led coaching, we help patients reduce visceral adipose tissue, improve insulin sensitivity, and restore metabolic health through lifestyle-first, data-guided care.

Visceral fat (VAT) is the dangerous, hidden fat stored around your organs that accumulates. when caloric intake exceeds energy demand, since glucose and fats that can’t be used gets stored as adipose tissue. This blog explains how ageing, muscle loss, glucose spikes and genetic factors all drive VAT accumulation — and how reversing the cycle requires restoring mitochondrial health, increasing muscle mass, and in many people, by reducing glycaemic overload.

Mitochondria are the power stations inside every cell, converting food into energy. But in modern life, with constant carbohydrate intake and low energy demand, they become overwhelmed. Just like solar panels producing too much electricity for full batteries, mitochondria have nowhere to send surplus fuel. This triggers oxidative stress, inflammation, and early ageing. Insulin is meant to divert excess glucose to safe storage — but when that system fails, metabolic chaos foll

If have been told your weight is high but your blood tests are “fine”, or if you are living with breathlessness or atrial fibrillation, you may be wondering how your body fat is really affecting your heart and lungs.

Carbohydrate Sensitive Phenotype (CSP) is not a diagnosis of diabetes or obesity. Rather, it’s a biologically driven pattern of visceral fat accumulation and carbohydrate intolerance which is highly prevalent in those with a raised waist-to-height ratio (WHtR > 0.5), triggered by aging, Western-style diet and lifestyle. More importantly, CSP gives individuals a name for their experience—one that invites support instead of judgement, and allows them to engage with food and hea

If you’re taking GLP-1 mimetics like Mounjaro, Ozempic, or Wegovy, you’re receiving a legitimate, medically prescribed therapy. Just like someone with asthma carries an inhaler, or a diabetic uses insulin, there’s no shame in needing a jab to support your metabolic health. Whether you are travelling or attending a hospitality event, here are some tips on how to navigate these new waters.
