Japan’s commitment to public health is exemplified by its ‘Metabo Law,’ a piece of legislation that legally mandates waist circumference checks for adults aged 40 to 74. This measure, officially the Metabolic Syndrome Prevention Act (2008), is designed to combat the health dangers posed by metabolic syndrome. The law ensures that citizens undergo annual health screenings that incorporate a specific waist measurement. These measurements serve as crucial indicators for elevated risks of visceral fat, a factor strongly associated with heart disease and reduced lifespan. The established waist limit for men is 85 cm (33.46 inches), and for women, it is 90 cm (35.43 inches). Individuals whose measurements exceed these benchmarks are provided with free resources, including nutritional advice and exercise guidance, to help manage their health. The overarching aim is to foster preventative healthcare and reduce the prevalence and cost of lifestyle-related diseases within the country.
