"My question, is it ok to occasionally have a high carb meal (such as a

few slices of pizza, a burger on the run, lunch at Sizzler, etc),
provided you go straight back to the LC meals the next day, and limit
to
20g for a day or two (two day induction say).  With four slices of
pizza
at dinner, but low carb meals the rest of the day I calculated you'd
probably be around 80g.  Given the exercise I do for all I know it may
not be enough to knock me out of ketosis anyway.

It seems to be to me more psychological, and helps to just break things

up.  We were looking at no more than one, maybe two meals a month.  Say

if we wanted to go to a chinese restaraunt and enjoy a meal with some
fried rice.

I'd also be selecting the meal looking for what would be lowest in
carbs.  For instance I looked at the nutrition info published on the
Dominos Pizza website and ordered the pizza with the lowest carbs per
slice.

Provided we don't fall back in to old habits of eating fast food for
convenience I can't see a problem.
My main question was were there any positive/negative health effects to

giving the body a burst of carbs periodically.

Any thoughts ? "

It depends where you are in terms of weight loss, what your
expectations are, and how often you do it and for how long.   For
example, for someone in maintenance having a higher carb meal once or
twice a week is a lot different than someone who's only been doing
Atkins for a month and still has 30lbs to lose.  The maintenance person
is where they want to be, knows the plan works for them, has learned
how to eat correctly, etc.  If they do add a few pounds, or carb
cravings return, they will very likely be able to deal with it and do
the right things to get back on track.

For someone who's only been doing Atkins for a month and still has a
lot of weight to lose, it's far more dangerous.  Without all the
positive experience and knowledge it's far more likely that a venture
into high carbs for a day will then lead to another day, or maybe 3
days.  Even doing it one day a week may lead to very slow weight loss
or none at all.  Then after a month of no weight loss, they are more
likely to conclude that LC doesn't work and give up.

It's interesting that pizza was one of the examples of food that you
want to go off plan for.  Instead of doing that, why not make a LC
version?   There are excellent solutions available, ranging from making
it with no crust, to using a LC crust, either mix or ready made.  Crust
recipes are available on LC and Loving It on foodtv.com.  Carbsense
makes and excellent parmesan/herb mix.  I wouldn't go crazy with either
of these.  They are certainly not for induction, however during OWL,
they are fine for occasional use.  Certainly a lot better than going
the high carb route.

I have a rule. ( I'm not on induction) When I'm at a party or what ever- I
do take a tiny portion of that special dish. I now know what it tastes like,
and most always, I don't want any more. I never go to a party hungry, unless
I know there is low carb food.

You can eat anything...if the piece is small enough. There probably is a
wiser choice of what to eat, though.

There is nothing wrong with eating high fat foods, on a low carb diet.

Watch what happens the next day rather than the same day. You may find
yourself overeating, and that would be because of the carbs that you
ate previously.

good for you, bad for her.
