Moderation Keats, don't get too stressed over it, just get back to your more sensible place and work your way back into the overall plan you had...Lots of fat in a short period, as you know is really gonna hurt you, literally, I was talking to a friend of mine (A doctor and nutritional therapist) and she still maintains the old saying of everything in moderation (to a large extent)...Try to stay moderate with your fat intake until you are on the other side of your op, this is gonna make life easier for you post-op, and if you do fall over, just accept that one day won't do too much damage, and get back on plan the next day, no need to go extreme either, as in eating diet dust and calorie free diet lettuce all day, in some over compensating fashion, just get back to being careful and moderate and try to eat as close to your plan as poss, work it one day at a time...Best wishes...
