I didn't follow my pre op diet to the dot. Is there a risk my surgery will be cancelled if I don't lose the desired weight?

Hi there, I'm a 28 y/o. My sleeves surgery is in 5 days, the exact date is May 1st, 2015. My big probleme is following my pre op diet. My dieteciant gave me a very restrictive diet to follow for 2 weeks. I really did what I could do, but I couldn't follow it exactly as she said. I did my best and I had lost 8 pounds so far. My starting weight was 263 with 5"7" and I didn't have any health problems. Thanks for your time. Best wishes, Youma
