It seems us hacker news readers certainly love nitpicking. I'm not talking about traditional HIIT (spring, walk, sprint, walk, repeat until you're dead). I'm talking about very fast weight training (Vince Gironda ftw!) which gives gives you plenty of cardio. Done on an empty stomach this demolishes your fat reserves.

I read your article and this quote stuck out the most: "The simple fact is that, given that most people train like wimps, if you get them to work harder for a change, good things usually happen." Going to the gym and talking with your buddy is not exercise, but it's exactly what the average gym-goer does.

Between that article and the other one I read which it linked to, Steady State vs. Interval Training: Summing Up Part 2, it seems to prove my point, which is that you can train high-intensity like interval training provided you give yourself enough carbs.
