I used to go to the gym and go like the fornicating clappers on the exercise bike at full chat and wondered why I wasn't shifting any excess weight, until the gym instructor told me I was wasting my time as I would get fitter doing that, but not leaner.
sustained bouts of low intensity exercise cause your body to start using up fat storage.
One of the major problems is that there is so much conflicting advice from the 'experts'. For example, I've read two people (including that Body for Life 'guru') who insist that you'll shift more weight through a hard 20 minutes on the treadmill than through an hour pedalling along sedately on the bike.
I've personally always found that I get more results from high-intensity work-outs, though I mix it up a bit. Best one for both CV and weight loss I've found is a 10-minute warm-up on the cross-trainer (around 130bpm) then a 20-minute run where I do 2 mins on 8km/h, 1 min on 10km/h, 1 min on 12 km/h, 1 min on 14, 1 min on 16, then back down to 10 and repeat through up to 16 another three times, before peaking on 18km/h for the 19th minute, coming back down to 8km/h for the final minute. Then do 10 min cool down on the bike (130bpm range again).
The beauty of it is that you can adjust the speed to suit your fitness level, so when I was coming back from injury I was doing four lots of 8,10,12,14km/h, and at my peak I was able to do 11/13/15/17km/h.
Doing it in such a measurable fashion also really allows you to keep a real tab on your fitness level.
Sorry, probably sound like a real geek after all that
