olive oil

I'm currently at 9% body fat and I want to cut down while also adding some lean muscle mass to my frame. I have a very clean diet and I eat about 4 to 5 meals a day. I have been cooking my own food and this has been helping me shred down, my question is how much olive oil do you guys recommend...

I was watching the food network and the chef was putting tons of olive oil in his food. the guy though wasn't in great shape lol. he said lots of olive oil is good for us cause it is good fats. I know nothing about nutrition so hoping to get some insight on if i should be using olive oil too...
