Felt like I'd chime in with some progress I've had lately with losing weight, especially since there's a tie-in with gaming. I'm six feet and was up to about 360 pounds not very long ago. However, over the past month, I've been losing almost five pounds a week in a way that I doubt very few people would recommend (especially in this thread) but works really well for me and maybe it'd work for someone else who hates the drudgery of exercise but enjoys gaming.
Willpower to exercise and to exercise regularly has always been an issue with me. So, exercising is kind of boring but... gaming is kind of fun. Thinking about that, I bought a stationary recumbent bike, chopped the top of it off, then built a table over top of it (using terribly warped wood). So, I PC game while cycling; it can be a little sloppy so I wouldn't play anything you're seriously competitive about but I can get by with most games. It can be easy to lack in intensity if you don't pay attention but I found if I remained cognizant of that, I was able to keep a good intensity while having the time go by pretty quickly since I was playing a game.
Naturally, I'm also eating responsibly now without going into a super restrictive diet that I wouldn't want to maintain for life.
Recently I bought a heart rate monitor to keep me more honest about maintaining a consistent intensity. It will alert me when I go under a certain threshold. I do this for about 15-20 hours a week and it doesn't feel like a huge burden because I'm gaming. I don't know that I could physically or mentally keep up with a proportionate amount of HIIT in terms of calories burned (I'm down to 304 pounds now). The last four weeks have been 5, 5, 4.6, and 4.8 pounds lost and I think there's the possibility of doing better now that I have the monitor.
Of course, when I get closer to my goal weight, I will likely stop doing this (certainly the volume of it) and do HIIT and strength training, but this has allowed me to make fast progress without feeling like quitting.
