There are a lot of factors that come into play to determine how much weight you will lose the first week. If you go from eating a high number of calories a day and many "bad" foods with lots of salt, etc. and go to a very low number of calories a day with mostly healthy foods, you can lose a good amount of weight the first week. A lot of it will be excess water weight that you are shedding from making your diet more healthy.
When I was 230 pounds and started "dieting" in a serious weight loss attempt about 7-8 years ago, I lost 6 pounds the first week and 4 pounds the second week for a total of 10 pounds in the first two weeks. The weight kept coming off at a rate of about 2 pounds a week thereafter. I ended up losing 60 pounds in about 8-9 months and then proceeded to put nearly all of it back on in the next few years. When I finally decided to try to lose the weight permanently starting in 2006, my weight loss the first two weeks was much less. I started at 220 pounds but I only lost 3 pounds the first week and 2 the second week. So I essentially lost half as much as the previous attempt. This past January I got back on track with losing weight after I maintained about 195 lbs for the past 18 months. Because my eating wasn't too bad during that time, my weight loss started off slow and has remained so. I think I lost 2 lbs the first week and then nothing the second week and then have lost about one pound a week since then.
So all of this means there is absolutely no way of knowing how much you will lose at the beginning of your weight loss efforts. Yes, it is much easier to stay motivated when you lose a lot to start off with, but the key is that no matter how much you lose each week, you stay with the plan and the weight WILL come off in time. Even at a pound a week, you can lose 50 pounds in the course of a year. Try not to make any drastic changes that you won't be able to live with permanently. Good luck!
