Lost 60 lbs so far, 20 left - F/23/5'7"

Thanks for all the comments, guys! I appreciate the encouragement and am happy to offer inspiration to you as well!

Oh my goodness! You look fabulous! My goal is similar to yours. I am 5'7" and I'm aiming for a 55lb loss, but I do know that is the top of my goal range and I really need to lose between 55 and 75 pounds. I have lost 11 pounds so far. I'm determined to make it this time. I do have a few questions for you;

1. How did you determine what your goal weight would be?
2. Did you have to adjust your diet and fitness along the way? And if so, how and what did you do?
3. How do you reward yourself for attaining goals? I've been trying to think of non-food (LOL) rewards.

Thanks for offering to answer questions - I hope to be in your position some day!

To answer your questions:
1. When I first started, I chose an arbitrary goal of 175 pounds. Weighing any less than that was inconceivable to me, so I figured it would be a good place to aim for. As I lost more weight and had my body fat analyzed in a bodpod, I realized 160 would be a much healthier, and in fact obtainable, goal. Really, smaller goals are what are most inspiring to me, though, as they give me acutely attainable goals.
2. I started at about 1600 calories and slowly whittled down to 1200. At 1200, I would sometimes get quite dizzy and didn't always feel 100%. I've since started a very active job, luckily, and can get away with 1350 calories a day with the same weightloss and less dizziness. Anyway, so yes, I lowered my calories as I lsot weight. As far as exercise, I never really altered it a whole lot along the way... I just upped the intensity and pushed myself to new goals as my old routines got too... routine. For exercise, for me it's always been about making myself uncomfortable... pushing myself a little further past what feels hard into what feels impossible... running until I want to die, and then running 10 seconds longer... or holding a plank until I feel like my abs will explode, and then holding it 5 more seconds... things like that.
3. Haha, this one I kind of use reverse psychology on. I reward myself with things I need. None of my pants fit at ALL? Looks like I'm wearing dresses until I meet my next goal. Hair look like a bird's nest? No haircut allowed until my next goal. Stuff like that really pushes me, because I know that I'm going to start suffering a little if I don't make my goal.

Oh you look so good and so happy!! Keep it up! May the next 20 fall off swiftly

ETA: Did you run throughout your weight loss months?

Yep! I've been running the whole time, save for a few lulls. I never got any kind of huge endurance, though, because I never really pushed myself hard enough. That's my goal right now, though!
