Exercise>diet, make a diet just to cut of 500~1000kcal of your daily ingest is idiot. Just buy a threadmill and run, last year I was trying OPM routine and lost around 20 kg. in three months. I was short 7 kg of my ideal weight but then my threadmill explode. Run is a hack, because the kcal you burn is proportional to your weight, running 10km has less impact the more you get close to your normal weight. Then you have to increase the speed and distance. But why threadmill? too lazy to go out and you can watch videos/series at the same time.
