Some of the initial weight loss was water weight, and you may gain 5 lbs after today, which is also water weight. Over the next few days you will probably re-lose some more water weight that you re-gained with the binge.
Of more concern than your weight fluctuation, which happens, is the binge. You need to figure out what is causing that. If you do, you can lose weight steadily. It may taper off to 1-2 lbs a week, after initial water weight is gone, but if you can avoid the binges, and stick to it, those pounds add up quickly. The most important part of weight loss is not the week of eating good, since most of us are professionals at losing weight. It is avoiding weight re-gain after we have lost it.Finding out what causes this, and preventing it from happening, is ultimately the difference between success and failure.
Find a way to lose more pounds than you regain, and with a little patience, you will eventually hit GW.
