I also was banded April 10th. I was told to have clear liquids for 5 days. Then do full liquids, which includes things that will go through a straw...like V8 juice, drinkable yogurt, skim milk, and anything that is pureed to a completely smooth consistency (no lumps or bits of anything) and then THINNED enough to go throug a straw). BUt do not use a straw. To thin purees, add appropriate liquid--water, juice, non-fat milk or broth. Stay on this diet until day 14 after the surgery.
After the 14th day, go on soft/mushy foods until day 30. THis is any food you could eat if you didn't have any teeth. Take TINY bites (no bigger than a pea) and chew VERY well (15-20 times each bite) and eat very slowly and carefully.
Full liquids, as given to me by my doc include nonfat milk, drinkable yogurt as long as it has no chunks of fruit or anything, any full strength juice. Vegetable juices are preferred over fruit. Any of the low-cal protein drinks, any purees thinned to liuid consistency...pureed meats, canned or cooked veggies and fruits. Lofat ice cream, pudding with nonfat milk, low-cal smoothies. Thinned cream of wheat, thinned oatmeal or thin mashed potatoes with NO lumps, mashed/thinned cottage cheese. ANY chili or soup as long as it is blended to puree and smooth any noodles, meat or veggies in it. Smooth applesauce. Frozen juice bars, lof fat fudgesickles. Pureed and thinned refried beans with guacamole if you like. Meaty spaghetti sauce, pureed and thinned. Chicken with BBQ sauce or ketchup, meatloaf with ketchup, thinned and pureed.
Remember: all Full Liquids must be pureed and thinned enought to get through a straw.
I hope this helps you.
