after my first weigh in on the saturday, i had my first sunday and the temptation struck (sunday roast) - i could not resist the temptation and had a small meal of chicken, mash, broccoli, carrot, swede and sprouts. Not happy with that, I had 2 lower fat hot cross buns, 3 chocolate digestives and then at night a toasted ham and pickle sandwich. Now that is a spectacular dive into self sabotage - yet i still lost 5 lbs that week when i weighed on the saturday. This is despite the fact that it knocked me out of ketosis and it took 3 days to get back into it.
I have learned my lesson - i won't do it again. Perhaps I was lucky but if you don't consume the calories, you must be burning the fat to keep your body going.
I am not condoning 'cheating' but letting you know that if you are asking because you have already eaten, all is not lost.
