Eat what you want, portion correctly (this is key) and stay active when possible.
I went from 220lb down to 170lbs, and gained back 5lbs of muscle in under 1 year, no supplements aside from vitamins ans minerals. Never went to the GYM, either
Just became more active with my recent lifestyle change. I've also done intermittent fasting, which is the primary factor in keeping the metabolism strong, and stomach coming down in size..
