My doctor’s office said I need to buy the food from them which is 5-6 meals a day of boxed foods such as chicken noodle, chicken pasta, shakes or puddings, bars, eggs, ECT... I am on a 3 week diet to get my BMI down around 50, and shrink my liver. The cost is 85.00 a week for the food I bought 2 weeks on the day of my pre surgery testing. Day one I tried the eggs, chicken noodle soup, and strawberry pudding/ shake, one was worse than the next. So I researched pre-op diets for lap-band® and found high protein, low fat, low carbs, and low sugar should do the trick. Results 395lbs on June 7th and 381lbs on June 13th, and BMI went from 54 to 51 in 6 days. I will do the liquid diet the last 3 days before surgery. I just wish I could stick to this diet and would not have to have the surgery, but the band is a tool I really feel I need to help me control portions.
