I believe I just saw an estimate of ~300 pounds. Wikipedia carries a South Korean government estimate of 290 pounds in 2015. Officially, he is 8 inches shorter than Trump. Viewing pictures of them together, Kim clearly has pudgier face and jowl than Trump. But adjusting for the official height difference, can he possibly be much heavier than Trump? (Never mind Trump's 'official' weight.)
I'll leave the stare-and-compares to the kids in the ATATT (all Trump All The Time) room downstairs. I do not recall that P45 is a chain smoker, nor is he a large scale consumer of a certain product made famous by the Cognac region of France. Un is clearly not in the best of health, but it's also fairly clear that he's not really doing much in "running" the DPRK. One expects that they'll prop another Kim up for the people to fawn over when Poo-II kicks off. There's a gaggle of male octogenarians that do all of the heavy lifting in the Hermit Kingdom. Unlike the ones over here THOSE cats are 4-D chess kinda smart. Sis is pretty active, and has an icy stare that can reverse global warming! Kim Yo-jong is juuuuuust the person you want running something called...."The Propaganda and Agitation Department of the Workers' Party of Korea." They call her the 'Vice' Chairman but hey....that's Asia for you. If they were worried about making an EEO pick they would put her in "charge" and let the world marvel over the "diversity" of their new leader (in a country that makes Japan look like the Great Melting Pot!) and it's probably a bank-shot that they're noodling over - but, thankfully they're probably not ready to shake things up quite that much. Quite frankly, I'm glad! KYJ looks kinda feisty.
Amphetamine and opioid use is common in North Korea. Dictators are also known to have a higher prevalence of such use. KJU?
