Insulin resistance is one of the most common and modifiable drivers of mid-section weight gain, fatigue, cravings, blood-sugar swings, and long-term metabolic risk. The encouraging part is that it is highly actionable and, in many cases, reversible.
A simple screening tool that is useful in clinic and at home is the waist-to-height ratio. If your waist circumference is half your height or more, this strongly suggests excess visceral fat.
Insulin resistance develops when cells stop responding efficiently to insulin, meaning glucose is less easily moved from the bloodstream into muscle and liver cells. The body compensates by producing more insulin, which drives further fat storage (especially around the abdomen), increases hunger, and worsens inflammation. Over time, this pattern can progress unless interrupted.
Visceral fat is often described as deep abdominal fat, but that undersells its impact. This is not the fat you can pinch under the skin. Visceral fat sits around and between the organs — the liver, pancreas, intestines — and it behaves more like an active endocrine tissue than a passive energy store.
Visceral fat releases inflammatory chemicals and hormones directly into the portal vein, which drains straight to the liver. This is why even relatively small increases in visceral fat can have significant effects on health. It is strongly linked with insulin resistance, fatty liver disease, cardiovascular disease, type 2 diabetes, hormonal disruption, and accelerated biological ageing.
Inflammation is both a cause and a consequence. Visceral fat produces inflammatory cytokines, which interfere with insulin signalling and further increase blood sugar and fat storage. This creates a self-reinforcing loop: inflammation drives insulin resistance, insulin resistance promotes visceral fat gain, and visceral fat feeds inflammation.
Meals should be built around protein, fibre, and whole foods to reduce insulin spikes. Liquid sugars, refined carbohydrates, frequent snacking, and late-night eating keep insulin elevated and should be reduced. Alcohol deserves special mention: it directly promotes visceral fat storage and liver fat, even in people who are otherwise health-conscious.
Movement is non-negotiable, but it does not need to be extreme. Resistance training builds muscle, which acts as a glucose sink and improves insulin sensitivity long term. Walking after meals lowers post-meal glucose and insulin. Even short, regular bouts of movement are effective.
Sleep and stress management are critical. Poor sleep increases insulin resistance within days. Chronic stress elevates cortisol, which directly drives visceral fat storage.
Hydration and inflammation reduction matter. Dehydration increases cortisol and worsens blood sugar regulation.
For susceptible individuals — including those in menopause, with a history of dieting, chronic stress, or metabolic conditions — progress may be slower, but it is still achievable.
