Also, track your calories. You may not be eating much, but you may be eating the wrong foods--foods filled with fat and calories. You'd be surprised how many calories are in foods you thought were okay. Until I started tracking everything that went in my mouth, I didn't lose. I sometimes don't like to admit that I messed up, but I have to do it or I'm cheating myself--no one else. Also, check your thyroid. I have a chronic problem with my thyroid (had part of it removed). If your thyroid isn't working properly (hypothyroidism), you can do all you want and you still won't lose weight.
