Intermittent Fasting - All cals in an 8h widnow

Hi i'm thinking of trying intermittent fasting as of tomorrow - eating all of my calories within an 8 hour window (12pm-8pm)...

Does anyone do this, if so any tips?

Also just curious, does it work for some types of people better than others? I read somewhere it is better for people who have a lot to lose.

I have already lost over 50lbs and I'm just looking to shift the last 10-15lbs before the summer.
Thanks

ps. if anyone does do this, please friend me for mutual support :)
