Treadmill routine -advice

[a05jwal]

goal is to lose weight so 3x/week I do a routine on a treadmill and just wanted to get some opinions:

I set it at an incline of 1 with 4MPH, then each tenth of a mile I increase the incline to 2, then next tenth of a mile, to 3 until I get up the the maximum incline of 15. Then I bring it down by 3 numbers each 10th of a mile until I am at an incline of 1, usually takes about 30 min. I thought this might be good because it is high intensity for some time brought back to mild, what do you think?

you'll burn more fat if you go harder earlier and easier later...you'll need some weight work also if fat loss is the goal...and food needs to be organised
