Have to agree with Blaster to a certain degree, lifting it's self has very little to do with getting rid of body fat, it's how you lift. If applied, the PHA system and other versions of circuit train will burn the most calories for the effort put into it. This will build stamina (strength & endurance) unlike most systems of training. But, by and large, the better way is to watch the daily carb's intake while doing stamina training. Tabata (a very superior means of cardio training as regards fat burning) training (or versions of it) is also a very effective method. This can be biking, rowing machines, rope skipping, short sprints, punching a heavy bag, etc. Cardio training does not have to mean hours of running or using a tread mill every week.
Take 30- 45 minute walks by all means, at a faster pace. Some studies have suggested that it may be equal to or even a better method than long run's for fat reducing and should not induce some injuries that running can produce. Easier on the knee's, hips,lower back, ankles, feet, etc. Coming to the bottom line, that dirty four letter word "Diet" should be the main concern. That does not mean 800 calories a day (you may lose more muscle mass than fat) but can include up to 2,500+ calories a day on a well planned out low carb diet (This is not the Atkin's versions). Even changing to whole grain quality carb food's and going from meat to fish or chicken can make a favorable difference. Good Luck.
