Add up the carbs you ate during your little binge. If it was less than 3500 calories, then you have not gained back a pound of fat- it will be water and you may have taken yourself out of ketosis. Some people who are doing weightlifting actually have a day of high carb intake and it does not set back their overall fat loss.

Just get back on track and learn to pay attention to your fat loss, not your weight. I just wish Atkins had instructed people to not get on the scales at all as part of the deal.....they fluctuate wildly and just make people miserable as a result if they 'believe' them on a daily basis. Weigh four times a month and take an average of that. Get calipers measurements of BF% as a more accurate estimate of what is going on and watch your clothes shrink. Most people on average over the whole time of weight loss only lose about 3-4 lbs a month, so you may be ahead of yourself. Relax and get your mind into this as a WOL.
