Welcome to 3FC =)
You'll want to have 3 basic ideas about things.
1) Food Plan. Eating less than we expend is how basic weight loss works. (Calories in vs. Calories out.) Now this differs from person to person, but you'll be looking to put together a plan that allows you to keep track of your food and to moderate your intake.
If you're unsure of what kind of plan to use or want a little direction, there are a list of some of the more popular ideas under Diet Central. Now, keep in mind they aren't the only plans out there, just ones that we see frequently around 3FC =)
2) Move more. It's as simple as that sentence. Add activity. If you're sedentary you don't want to jump into a full-tilt work out where you might actually injure yourself, but you DO want to incorporate more movement where and when you can. It can be as simple as taking the stairs, and parking further from a store so you have to walk a couple extra steps. You can schedule in short walks, or find an activity you like to do and start planning to do it more. Over time, build it up, keep it a habit, and eventually you'll be surprised at just how much more movement you're getting into your life.
3) Patience. Persistence. Perseverance. Weight loss is by no means an easy process, but we must be patient with ourselves and the plans we've chosen. We must be persistent and stick to our promises. And we can persevere through the toughest of challenges!
