Track you calories and start small in terms of exercise. Eating, drinking: track everything. In my experience it does the trick on its own. What you're aiming for is caloric deficit, so don't overcomplicate it. If there's a diet that works for you, great. If not, just analyze your intake from time to time and you will come up with your own diet automatically. Exercise: depending on your current level of fitness, I'd strongly suggest taking small steps. Changing your diet while getting started with running and 1-hour workouts three times a week sets you up for failure. If you haven't been active before, aim for N steps of walking a day. That's it. Be patient, the first results will show in 2-4 weeks. Good luck!
