I want to second the healthy habits. Everyone needs nurishment in order to be healthy. The more you work out, the more your body needs to replenish, so don't forget this as you workout.
I started my latest "push" towards my goal weight of 185 lbs on October 31st, well technically a week or so before this. But it required a dramatic change in my lifestyle. Now I love me some beer, but it is just empty calories and went directly to my waist, so I quit, cold turkey. I also started tracking what I ate so that I became more aware of the "stuff" I put in my mouth. This helped me go from 212 on 10/31 to 189 today. Now that might seem like a lot for just changing what I eat, but I also ampted up my workouts, trying to get in a 5 mile run everyday, plus daily exercises for my glutes and thighs (trying to shape them up a little more through non-surgical means). Now add onto this a few hours of roller derby and I burn a heck of a lot of calories per day, so if I reduce the amount of "bad" calories and food that I intake by replacing them with "good" calories and food, I feel better and have actually had positive results.
Now you may be thinking 189, that isn't very light, well I am 5' 15" tall, so I am a giant

And ideally if I can stabilize my weight at 185, I can maintain enough muscle and body fat to still look feminine without looking too gaunt or underweight. So keep in mind that body measurements and "ideal" weight ratios vary from person to person. You need to find the right solution for you so that you remain healthy, happy, and IMHO fit.
Stay active and you will reach your goals!! (That is my inspiration speech)

Best of luck to you!!
