Randomly, I'm watching a DVD about fat burning right now that I got from the physical therapy practice I've been going to for my knee.
It's very good. I recommend it. Doug Kelsey, the head PT of Sports Center Austin, has a blog he updates weekly with great physical-therapy-related info:
... and he's made a handful of DVDs which are recordings of free informational sessions he does at his office.
The fat burning one is, so far, very good. He talks very directly to the science behind metabolic rates, interval training, alcohol's effect on weight loss, stress's effect on weight loss, etc. He's direct and clearly knows his stuff. Best of all, for a DVD about a fitness topic, he uses remarkably few stupid buzz phrases, he doesn't have terrifying gleaming white teeth, and he doesn't resemble Tony Robbins in any way. No creepy cult-like self-improvement stuff here.
Anyway, I'd recommend it as good viewing if you want help shedding pounds. It's the "Fat Burning 101" DVD on here:
