The "Metabo Law" in Japan requires annual waist measurements for those aged 40-74 to curb obesity and metabolic syndrome. If waistlines exceed limits, individuals must attend counseling. Employers and insurers must ensure at least 65% participation and a 25% reduction in obesity by 2015 or face penalties to fund elderly healthcare. While raising health awareness, critics note low compliance with exams and advice, rising childhood obesity, and risks of discrimination.
