I have tried that in the past, but never managed to get back on track.
It is very very very difficult to get back into it when you take yourself out of ketosis and start eating again. It keeps me on track anyway as I know that if I mess up, lord knows how long it will take me to get back on again (if ever!)
Here's what happens to me:
Go off the diet for a night
Try to get on again the next day, fail and say I will start again after the weekend.
Try again Monday and fail - then eat everything in sight because I know I won't be able to tomorrow.
Repeat on Tuesday
Repeat on Wednesday
Repeat on Thursday
I cant diet on a Friday, lets wait till Monday.
Spend the weekend eating EVERYTHING that I could possibly want and treat myself as I will miss it when I am back on CD.
Monday - Repeat the above week.
At some point I give up trying to get back on and go to WW or SW, and then because I don't lose fast enough I give up come off it, eat like a horse and then try CD, and repeat the above week yet again.
Next thing I know, I am heavier than I have ever been :sign0007: :cry:
Perhaps some people manage it better than I do, but I know that personally, I just can't get away with it.
Good luck whatever you decide
