Well, I'm confused again. I suppose it was inevitable, seeing as how my latest hobby of sitting around reading exercise literature fairly well sets me up for finding conflicting information, but anyway...

I've started a new workout plan. I'm lifting four days a week (Monday, Tuesday, Thursday, and Friday), with half an hour of cardio immediately following the lifts for those days. My question is this: since my goal is fat loss, would it be beneficial to continue a cardio regimen even on the three days I'm not lifting? In other words, would I see faster, steadier, and more permanant fat loss lifting and doing cardio four days a week, or lifting four days a week and doing cardio daily?

I should also point out that, when it comes to cardio, burnout isn't an issue I'm concerned with. I love it. If there's no functional difference between the four and seven day plan, I'll do the seven just for fun :)

do cardio 7 days a week with your normal weight lifting regime, do cardio as often as possible, if you work out and do loads of cardio it will help you get ripped faster.

Cardio 5 to 7 days a week is fine. I don't know if I'd say the more cardio the better. You probablly don't want to be doing 3 sessions a day or anything like that.
 
And remember after 8 or 10 weeks take a week off from cardio to keep your body getting use to it.

yeah don't overdo the cardio like cowboymouth said but if you do a lot of cardio it helps reduce and keep your bodyfat% low but you have to watch your diet a lot as well, i wouldnt take a week off cardio though rather just increase the intensity of it but thats my personal opinion.
