LCHF for Obesity & Metabolic Syndrome

Obesity in South Africa has more than doubled since 1990. The conventional explanation — that people simply eat too much and move too little — has proven inadequate. Despite decades of low fat dietary guidelines and calorie-counting advice, rates of obesity and metabolic disease have continued to climb. A different framework is needed.

Insulin drives fat storage

Insulin is the primary hormone controlling fat storage. When insulin levels are high — as they are after eating carbohydrates — the body is in fat-storing mode. When insulin is low, the body can access stored fat for fuel. This is not controversial biochemistry; it is the fundamental mechanism of energy metabolism.

LCHF lowers insulin by removing the dietary trigger — carbohydrates. With lower insulin, the body becomes fat-adapted: it burns stored fat efficiently, hunger hormones normalise, and weight loss happens without the constant hunger that makes calorie restriction so difficult to sustain.

Metabolic syndrome: the cluster

Metabolic syndrome is the cluster of conditions — high blood pressure, high blood sugar, excess abdominal fat, and abnormal cholesterol — that markedly increases the risk of heart disease, stroke, and diabetes. All five markers of metabolic syndrome are driven by insulin resistance. LCHF addresses all five simultaneously by targeting the underlying cause.
