Vacation weight

I have now done a week worth of fasting since the one week vacation. I gained 4 lbs on the vacation, and have now lost two of those. So my weigh-in this morning was 167. I guess that it will take another week of fasting to get back to my pre-vacation weight of 165. Two weeks of alternate day fasting is a high price to pay for one week of eating whatever you want, but at least those pounds are coming back off.
