I've been doing the milk and yogurt Pre op diet for 4 weeks now! Mainly to reduce my BMI and get it below 50 (was 57) as well as shrinking the liver! It's not been easy but I've got too much to lose (no pun intended) to cheat! Surgery was booked for 22/8/13 but has had to be re scheduled due to BMI still being 52! I'm determined to stick with it and do what ever it takes to have my wls. Watch this space.....???Š
