6-8 hours, if it's light food. For water, 4 hours should do. Keep in mind that these are general guidelines, and not individual ones. If your surgeon/anesthesiologist/general practicioner tells you otherwise, it is CRUCIAL to follow these directions. At least once a week, I tell someone their surgery has to be postponed because they didn't follow instructions...
Recovery time from surgery always varies. The length of recovery depends on how much progress a patient is making and what type of surgery was specifically done.
Your last meal before your gastric bypass surgery should be something that you love. You need to keep in mind that after your surgery you will be put on a special diet and you won't be able to eat the foods that you love for a long time. You should eat your favorite meal and enjoy every bit of it.
As, your surgeon and especially your anesthesiologist what you can eat and how long before surgery you can eat. The danger is that your body is asleep and immobile during surgery, so you may choke on your stomach contents if you've eaten too much or eaten too soon before surgery.
They say before a surgery you are supposed to eat 10 bananas you should stop listening to stupid doctors who have no clue on what they are talking about.
The diet you need to eat before surgery needs to be individualized. Only your doctor and nutritionist can tell you exactly what foods you need to be eating before the surgery, and when you need to start dietary changes.

Your diet will need to change both before and after surgery. Your doctor may recommend that you begin your pre-op diet atleast 2 months before the surgery. Your diet will continue after surgery as well. You will need to eat healthier foods and smaller amounts of food.

Most people need corrective facial surgery in order to eat and chew. This is called functional surgery
You are going to need to speak with the doctor that is performing the procedure. Most of the time you are not allowed to eat within about eight or so hours before the procedure is to begin.
Check with your doctor. They often will not do the surgery if you have been instructed not to eat or drink unless it is emergency surgery and you have to have it or you will, you know, die. It would not matter if you NEEDED emergency surgery.
