South Korea's spy agency is using high-tech 3D imagining to snoop on North Korea's Kim Jong-un to monitor changes to the dictator's physique.
The National Intelligence Service (NIS) said Kim Jong-un is in relatively good health, despite a family history of diabetes and high blood pressure.
The report comes after NIS briefed the country's MPs, the Yonhap News Agency reported.
According to South Korea, Mr Kim is 35 years old - North Korea says he is 34 - and has suffered a number of illnesses since assuming power in 2011 after the death of his father, Kim Jong-il, who suffered from high blood pressure and diabetes.
Kim Jong-un has put on weight since he assumed control of the impoverished nation and was walking with a limp and supported himself with a cane when he addressed a special session of the North Korean parliament in July 2014.
The dictator's dietary habits have been the source of speculation in the west. According to reports, he gorged on Emmental cheese as a student in Switzerland, craves expensive liquors and prefers Hennesy and Crystal, and gorges himself on luxuries like Kobe beef and sushi.
In 2014, he disappeared for a number of weeks and after some time, Pyongyang admitted its 'Dear Leader' was poorly - sparking new rumours he may have gout.
His Pyongyang henchmen revealed only that he had been struck down by a mystery illness, saying only that he was 'suffering from discomfort'.
'Based on his gait, it appears he has gout - something (due to) diet and genetic predisposition that has affected other members of the Kim family,' said Michael Madden, an expert on the North Korean leadership and contributor to the 38 North website.
Experts believe Kim may be deliberately gaining weight in order to look more like his grandfather Kim Il-sung, who is venerated in North Korea as the nation's founder and even now is still considered the head of state, with the title Eternal President of the Republic.
