1) ["In controlled settings, participants who remain in weight loss programs usually lose approximately 10% of their weight. However, one third to two thirds of the weight is regained within 1 year, and almost all is regained within 5 years. "](http://www.ncbi.nlm.nih.gov/pubmed/1580453)
2) Giant meta study of long term weight loss: ["Five years after completing structured weight-loss programs, the average individual maintained a weight loss of >3% of initial body weight."](http://ajcn.nutrition.org/content/74/5/579.full)
3) Less Scientific: [Weight Watcher's Failure - "about two out of a thousand Weight Watchers participants who reached goal weight stayed there for more than five years."](https://fatfu.wordpress.com/2008/01/24/weight-watchers/)
4) [The reason why it's impossible seems to be that although calories in < calories out works, the body of a fat person makes it extremely difficult psychologically to eat less.](http://www.nytimes.com/2012/01/01/magazine/tara-parker-pope-...) This is borne out by the above data.
5) [The only thing that does seem to work in the long term is gastric surgery.](http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1421028/)
Moreover, you won't find any reputable study on the web where the average person lost 10%+ of their body weight and kept it off for five years. Not even one.
The study people sometimes bring up is the national weight control registry. But it is a heavily self selected group of people who have already lost significant weight before joining - therefore weeding out most of the failure rate. And even then, only 20% of their audience lost over 10% of their initial body weight and kept it off for one year.
Also, it says that, "He writes his own songs and choreographs his own videos, which is unheard of in K-Pop.". This is however pretty much the norm for YG, the record studio he belongs to.
Big Bang's leader, G-Dragon, writes much of the music and lyrics for the group, along with T.O.P.

Also, they don't write their own songs, but YG band 2NE1 has a video with over 50,000,000 views, but it took a few years to get there: http://www.youtube.com/watch?v=j7_lSP8Vc3o
