I agree with whipa. Its only for the weekend so just try as much as you can to be sensible (eg. small cone with yogurt based ice cream or sorbet), stop when you feel full, look for salads & fresh foods at markets - that kind of stuff. It does also help to try to track as honestly as you can (well I found it helped).

I've had a few 'blow out' events and if I'm super good for the following few days it usually all evens out and although I might plateau for a week (or two) my next weigh-in is often a bigger loss. Hope that makes sense!

In 3 weeks I'm off overseas to see family for 4wks and I'm already mentally preparing myself for gaining back a few kilos. I'm going with an attitude of 'yes I will gain weight but be sensible and it shouldn't be too bad'. I'm also hoping that my family will be so surprised and pleased by how much I've lost since they last saw me that they won't 'sabotage' my efforts.

Enjoy your weekend!
