Didn't Loose Weight in 6 Month Supervised Diet

Hi there! I have Aetna...and I did not loose weight in my 6 month supervised diet. I actually gained 6 pounds. Is this going to cause issues with my approval? Any suggestions/

I also gained weight during my 6 month diet, and it did not affect my insurance approval at all.  My surgeon, on the other hand, was not too happy.  But I did the two week liquid diet, lost the weight, and everything was fine.
