Hi ebony
I think if its a high-carb meal it definitely could take a few days to get back in, and that's a pain if you know you'll be coming straight out of it again! Maybe making a plan for those days thats reasonably low cal but not low carb could be a good practice for after you've finished slim and save? I find I have to have a plan tho, otherwise I see "off plan" eating as a chance to go crazy and stuff myself!
Have been thinking through my christmas plans, have decided to low carb all the way atkins maintenance style, so less than 60g carbs, but including lots of lovely cheeses and meats, veggies and lovely creamy desserts! Will have dry white wine and try to keep the calories under 2500 (the wine should be fine then as although i'll be in ketosis I won't be drinking on an empty stomach/ vlcd). Am hoping I will STS over christmas which would be fab as normally put on half a stone! Then back on S&S from Jan til goal...
