Hi there Bukirouge
Well... the first problem is.... dieting. Around here you'll see a lot of people talking about changes they make. Permanent changes. Dieting tends to have this temporary mentality. In reality, if we go back to what we were doing
before... then all we're going to get is what we got
before... fat! So, say no to dieting. Say yes to changing your life!
There are a few ways to go about this... some people have a plan or program they follow, others are making baby steps by changing one thing at a time to become healthier & lose weight. If you have a look under Diet Central you'll see some of the more common methods being used successfully around here.
You say you're just movin' out on your own

Fantastic! And a little scary, eh? I have to say that one of the best things about being on my own now is the ability to decide what comes into my house, what goes into the fridge, and what goes into my mouth. You may find that it's easier to say no to overeating if you just don't buy the stuff that tends to lead you overeat!
I've got just about 100lbs to go, too

There's the 100 lb club to check out, and the 20-somethings

But, truly the whole site is great for support and friendships.
So! Keeping in mind that you want to take the weight off, but more importantly KEEP the weight off. Why not start with one thing in mind that you can do that will bring you closer to that goal? Drinking more water... eating a few more vegetables.... taking a short walk... small things
Make sure you look around & post wherever you're comfortable. We all can't wait to get to know you and help you on your way!
Best of success!!!
