Disappointment after liposuction. Why would the fat be too hard to remove? (photo)

I've just had liposuction on my abdomen, outer and inner thighs. When I asked the surgeon said he was only able to remove 700 ml of fat in total from all areas as the fat was too hard to remove from the stomach area. I was 165 lbs n 5'5''. I'm so disappointed as there is going to be no difference in the before and after I feel that I've wasted my money and in pain for no reason. Why would the fat be too hard to remove-be said I was a good candidate for the procedure! Photos are pre-surgery.
