How much can I lose?

Can't really tell that from pictures. :ohwell:

Depends on your goal to be honest...

You can use the formula for ideal racing weight as height in inches = weight in pounds....

That is a good formula that is used worldwide as a standard... But it might not suit your goals and might be too thin for some to enjoy or maintain... Just depends.

The real question is, what do YOU want to look like or do? If racing, you can use my formula to calculate ideal race weight within a few pounds. If not, well, honey, how do you want to look? No one can answer that honestly but you.

Why don't you want muscle? Muscle for women just makes you look lean and toned--you won't look musclebound unless you take steroids. Only men can look that way naturally.

Building muscle is how you will balance out and get to a good body fat percentage. The way you look now, I wouldn't suggest any other method.

And honestly? You might not lose much weight... but you'll be slimmer and stronger and look fantastic.

I want muscle, just not a lot, because if I take a long break from exercising, the muscle turns back to fat.. and I do take long breaks because I'm bad at moderation. I either move constantly all day everyday or I don't do much except fun stuff (swimming, walking around places, dancing).

That's not how it works: http://www.todayifoundout.com/index.php/2010/08/muscle-does-not-turn-to-fat-if-you-stop-exercising/

The reason you gain fat back if you don't exercise is because you don't change the way you eat to compensate. If you stop exercising, you need to cut back your caloric intake. But muscle BURNS fat, so you should want to maintain a good amount of muscle if you want to look good. You only have to work at building muscle a couple of times per week to keep yourself strong, so motivation is easier to come by.

You may be small boned, but a size 1 for someone who is 5'4" sounds awfully small. Are you sure your goal is realistic? Pictures can be deceiving. I still believe you should work to build fitness and strength rather than working to lose weight. But that's my opinion based on my experience.

Good luck!
