How much did you lose on Pre-Opt diet?

What kind of diet were you on?

I've lost about 4 lbs on low cal diet (still have until Wednesday May 28th) worried I should be losing 10 to 15lbs like the posts I read - doctor never told me an amount to lose - just do the diet.

I lost about 15=17 pounds on my preop.... I did a week of liquids.... then I did some liquids and a low carb high protein low cal dinner.... Then 4 days before surgery I went back to only shakes.... I use newlifestyle shakes

My doctor had me on a 7 day pre-diet of 40-50 carbs a day, liquids - broths, jello's, protein water drinks, unlimited protein shake drinks, protein food bars, and no sugar. I lost 7 lbs.
