I've lost big amounts before and it's like 80 percent what you eat and 20 percent exercise.I found eating foods high in protein that you can't binge on like boiled eggs as snacks helped and salmon is hard to overeat.a crosstrainer is a great exercise equipment or long walks.but it's about eating foods that make you feel full and moving more.if you eat foods high in protein like turkey you will feel full quicker and if you eat foods high in fiber it means your body will just sh#t it out.
