If all you care about is
losing weight then running should be your main priority. I hate running, as do most people, but it is worth it. If you can, pick an alright time of day, I usually run before bed or when I am at the gym. You pick a reasonable distance, and run it as much as you can, with walks in between. Eventually you will notice you can run the entire distance, and you may add laps. Try to do this every day, but you may need to add breaks in between.
