SEOUL (Reuters) - North Korean leader Kim Jong Un is believed to weigh over 140 kg (308 lb) according to an artificial intelligence (AI) estimate, a South Korean lawmaker said on Wednesday in a remark reflecting abiding interest in the health of the North's secretive ruler.

The health of North Korean leaders is typically a tightly held state secret, and speculation about the condition of the current leader Kim, believed to be 39 years old, has been recurring due to his heavy smoking, apparent weight gain and family history of cardiovascular problems.
