Caramello, I would have to agree with Suzanne 3FC; if you're cutting back your calories, then make really small changes. When I was figuring out what was best for me, I changed my calorie amounts a lot and my weight fluctuated like crazy and it took a long time to find what was reasonable.
I'm curious as to how much weight you are planning on losing. When I saw the 104 lbs, right away I thought: that's so tiny (but for me, I haven't weighed that little since elementary school)! I checked your BMI (body mass index) out of curiosity and you're at 19, within the healthy range (18.5-24.9). I realize that system is for "adults" (age 18 and up) so it might not be unreasonable to be a little lighter, depending on your frame.
Since you are starting at such a low weight, the weight will almost definitely be very very slow coming off, but that's healthier for you anyway. I'm sure you look terrific already, but if a few extra pounds are making you uncomfortable, it's wise to start taking care of that now before things get out of hand. I wish you luck and hope you find the support you need on this forum; it's been a great resource for me. Take care.
