New to this would like some tips!

Ive lost 50lbs without doing much, just restricting my portions and watched what I ate. I went from 266 to 220, I'm now trying to lose more by intermittent fasting and dont know much about it. I'm trying to do the 16:8 but I never get up at the same time every day and dont know if that will affect anything. I'll post pics eventually I just want to figure out what I'm doing first. Id love some tips and what helps for y'all and how you eased into it!
