For my workouts, which range from 3-7 days a week (usually 5-7, though some weeks are busier), I jog and do interval training (run fast for 3 minutes, walk for 2, repeat several times). I also lift weights about 2-3 times a week.
For food, I try to eat healthy choices. I eat lean proteins (chicken, fish, etc.), whole grains, lots of veggies, fresh or frozen fruit, and then make sure I have some treats so I don't go crazy. I've been collecting healthy recipes to try, though that takes some time.
I also kind of count calories. Maybe a couple times a week to make sure I'm not eating too much or little. I do pretty well eating intuitively for now.
The key is the pick a workout routine and new eating habits that you can maintain for many many months, and then that you can adjust to still be really healthy when you hit maintenance of your weight (in which case you'd continue that forever, basically).
Good luck!
