It's interesting how every doctor's post op diet is different. My Dr. and Nutritionist said everyone is different and some folks will start eating regular food quicker.
The main reason why they advise the softer foods for 3-4 weeks is so the stomach can heal where the band was installed.
If you go out and try to eat normal you could cause the band to slip by doing so. This is the reason for softer foods.
Personally, I was over cottage cheese about 5 days ago, and I've been eating lunchmeat sliced super thin from the deli, then cut up with a knife, and have had not problems.
My body needed real protien and that is what I was craving.
You'll know if you eat something you shouldn't. It will get stuck and you'll regret it.
Take your time, chew, eat slow, and stick to the 4oz rule IMHO.
If you can find a protien shake you like, I advise that as well. They do make you feel full for quite a while and you won't have those hunger pains.
BTW, I'm 12 days PO and I've lost a total of 19lbs.
