welcome aboard the board! I agree with lookin2lose about the mini goals, it's really fun to have a SET goal, achieve it, and move on to the next one!
My 2 cents is to investigate WHY you overeat, why you gained weight, be brutally honest with yourself, and try to find ways to overcome those reasons. If we never change the 'why' we do things, we can lose the same 100lbs over and over for the rest of our lives, but it'll always find us in the end.
Checking in with the 3FC is really helpful, motivational, and kick-in-the-pants if you need it too! Remember, no one has the "right" way to lose weight. Lots of people track every single gram of nutrition, other people (like me) basically still eat the same just WAYYYYYYY less of it and not so junky anymore. there's lots of ways to get there
Keep checkin' in and keeping us posted!
