North Korean leader has dropped about 20 kilograms, South Korea’s spy agency believes, and it dismissed speculation he was using a body double.

Iran PressAsia: Kim Jong Un tipped the scales at about 140 kg in 2019 and has dropped weight since then. 

South Korea’s spy agency said rumors the North Korean leader had been using a body double were groundless, based on their analysis that also used artificial intelligence. It added Kim appeared to be in good health.

The 37-year-old leader -- overweight and a smoker -- has been the subject of health speculation for years and his public appearances are closely tracked, especially since his family has a history of heart disease.

Kim has cut a much trimmer figure at his public appearances over the past few months, including a military parade in September and an expo of the state’s latest nuclear-capable weapons in October.
