I was taught for many, many years that fat intake was bad. That it needed to be a very small part of your diet. I've never liked that because fat adds a lot of flavor to the food. But I tried to be good and eat "right". However, when I took 90% of the carbs out of my diet I had to replace them with something. And the percentage of my calories that come from fat really went up. To between 35-40% of my calorie intake. (some days much higher I'm sure). It's in the meat, and the olive oil on my salad, the coconut oil I cook in. It's everywhere. Good thing that it's yummy.
Sometimes I have to remind myself that it's a good source of fuel for my body and doesn't cause my insulin to go wacky so it's ok to eat it. I get more flack from the fat I eat than from giving up sugar and wheat. But I explain that it's the body's preferred energy source, that's why we store it so efficiently.
