When I went through my pre-op diet I was hungry, irritated, and seriously reconsidering what I was about to do. I decided that if I could not get through what my surgeon wanted me to do before the surgery - exactly- that I was not mentally ready for weight loss surgery. I did it. I never strayed from the guidelines and I lost 12 pounds and felt really good about it the night before my surgery.
I know so many people personally that "try to beat the system". They figure out what they can get away with eating. Then they are stunned when the scale stalls or shows pounds gained. This surgery does not control what is brought to your mouth. For only a short time will it control how much of that food goes to your new stomach. This surgery is a great tool to give me a chance to break the cycles of bad habits. I haven't had fast food (pizza, McDonalds, Subway............) since January 6, 2013. Of course I miss it. But I will never give them a dime of my money again. I feel betrayed actually. All the money I have wasted on that garbage food- and in return I get 100 plus pounds of excess weight to carry.
I am not going to try to see what I can get away with. I am serious about getting healthy. So the only foods I eat will be what the bariatric surgeon says I can. High protein/ low fat and low carbs.
Mentally I have created an atmosphere for success. I go to support groups once a month for weight loss surgery. And I go to overeaters anonymous and I have a behavior therapist to visit 2x month. Matters of weight take place in the mind and this surgery does not take place in your head.
