Hi slimmerkay,
Well done for your first weight loss. I hate to say it, but in a week or so you'll probably be losing less than that. The normal and safe rate to lose on calorie counting is 1/2lb a week. This keeps your body healthy, because with too much calorie restriction, or calorie deficit, our bodies go into starvation mode and store up everything. Is also keeps our bodies working at their optimum if we lose slowly but steadily.
The first couple of weeks usually sees a lot of water weight loss which is what you'll probably experience too.
I know 1/2 lb is not a lot, and i guess if you work very hard and have a big goal to reach then you could lose more but it will not be good in the long run, because as soon as you finish the diet the weight will come back if you've lost it too suddently.
Remeber there are 3500 calories in a lb, that's a lot of calories!
Good luck on your weight loss, it will all be so worth it when you start to notice a difference!
