The diet programs for post ops differ with every surgeon, depending on his/her experience, and where the surgeon trained.
Although you may get tired of, or have a hard time following your surgeon's instructions regarding your diet, it is best to follow your own surgeon's instructions, since he/she is the one who did the surgery, and knows you personally. It is fine to know what other surgeons require, and patients say, but stick with what you are required to do, to assure the shortest recovery with least complications.
Don't forget your water, even if your meals have been upgraded to pureed and soft foods.
