First 3 to 4 days after surgery - clear liquids only.
No tea or coffee for first three months. No carbonated drinks ever.
5 - 6 weeks of liquid only diet.
6-12 weeks after surgery - food shredded in a processor.
No bread, potatoes, starchy vegetables.
Certain foods may never be tolerated - steak, pork, burgers; citrus fruit; high fibre foods; spicy foods; fried foods.
Now, to my way of thinking - if you can live the rest of your life eating such a restricted diet, you should have the willpower to diet effectively without surgery..

Other surgery includes gastric bypass - where food goes straight in and goes straight out. You are nowhere near heavy enough for such drastic surgery.
