In my personal experience, I have found way more benefit from lifting weights and cardio for losing weight as opposed to cardio alone. Since your body is healing and building from the weight lifting exercises, it increases your ****bolism for HOURS after each work out, which in turn burns more calories than a single cardio routine. You may gain a little weight at first as you start to build some muscle, but your 'shape' and athleticism will be improving regardless of what a scale tells you. Concentrate on what your body looks and feels like as opposed to what 'number' your weight is at. Especially for the first few weeks. Eventually, your weight will take care of itself as you continue your work-out program.
I would suggest doing a workout that covers your whole body and uses weights that restrict you to 3 sets of 10. As your strength improves, increase the weights and keep pushing yourself to more weight at the same reps. Superset your workout movements too to keep your heart-rate up. A good example of such a work out is called "Get ripped like Brad Pitt from Fight Club in 12 weeks" or something like that. I don't want to post any links or anything cause I not sure if that is an offense ?? Work out 3-4 times a week for about 45-60 minutes each and run on your days off for a minimum of 20 minutes. If you don't see results that you are happy with after doing this for 2 months....I would be really surprised.
Good luck man.
