Slim and trim Kim Jong Un

At a recent North Korean function, Kim Jong Un looked thinner and more energetic than he has in years.

Kim’s weight loss first became apparent in June, when he made his first appearance in a ruling party meeting.

North Korean watchers said that Kim, who is about 5 feet 8 inches tall and has previously weighed about 300 pounds, may have lost 22-44 pounds.

Most experts say that Kim’s weight loss is more likely a result of efforts to improve his shape as he enters his 40’s rather than an indicator of health problems.
