Obesity is becoming a growing concern in Japan, with changes in dietary habits, sedentary lifestyles, and an aging population contributing to the problem. According to a report by the World Health Organization, 26% of Japanese adults were overweight as of 2016, while 4.3% were classified as obese. The traditional Japanese diet rich in fish, vegetables, and rice has been replaced by a more Westernized diet high in fat, sugar, and processed foods. The Japanese government has implemented various initiatives to address obesity in the country, including promoting healthy eating habits and encouraging physical activity. Healthcare professionals also play a critical role in addressing obesity by providing education and support to patients.
