I agree with onepack. ON whey is only effective for post workout.
Running is definitely would be a good cardio for you if you want to lose those weights. Try not to eat before your workout. As an ex fat boy, I emphasis more on cardio then weight training. As for me I use to hit 20-25 reps for fat loss. It works well for me. Motivation is very important. Keep going! You will do just find!
