Hi and welcome to 3FC. A GREAT place to be with lots of info, support, encouragement and advice.
Yes, most of us here have made the commitement to change our "lifestyles", no diets, per se. Adding in healthier foods and elminating the high calorie/low nutritional value foods. Adding in activity and exercise to our daily lives. It is a process and can be tweaked and improved upon as you go along.
I caution you to watch out for the Saturday "cheat" days, they often can wipe out a weeks worth of good eating. You may just want to add a couple of hundred extra calories for just this purpose, making it a "controlled" cheat.
Oh and for sure you'll want to stick around even when you do get thin, we've got a great group of maintainers around here. Thinking about maintenance now, before you even hit your target weight is a good idea - and exciting to think about.
Good luck to you.
