It is certainly not an abnormal behavior. The reality is that you will eat these items again though. I have eaten Doritos gasp! I have eaten a small bit of a brownie or a cupcake, oh no!
The difference is after surgery you are most likely going to experience less tolerance and less cravings for these items. Once you start to lose weight, you will desire them even less because your progress and non scale victories will motivate you to stay on track 90 percent of the time.
We are human though, and food tastes good. We are meant to enjoy certain things in life, and in moderation I think food can be one of those things.
I would try and stay away from that food funeral thinking. You’re going to set yourself up for having a hard time staying on track for your pre op diet. You don’t want to really gain twenty pounds before surgery anyways and I would not test the surgeon on his no gain policy with a large gain.
Set yourself up for success preop, and you can definitely lose some pounds and have a smooth transition for after your surgery.
