I am doing Paleo right now, coconut oil is a big part of that, although I have been using coconut oil for about six months, before I went onto Paleo. I was skeptical about eating so much fat, afraid I would gain, but it's been fine, I have even lost a few pounds. It's far better to eat eggs for breakfast and have stable blood sugar, than to eat granola and be hungry again in a few hours. No more blood sugar roller coaster. Some people think they lack self control, when it is the food they are eating that is causing them to make poor choices. Even complex carbs can set you up for blood sugar fluctuations, setting you up for failure the rest of the day.
I had a hard time giving up my morning granola. Due to medications I take and some health issues, I just could face eating eggs in the morning, although I have known for a while cereal wasn't good for me. I weaned myself off by first cutting the amount in half, and eating eggs a few hours later, then substituting deliveredd almonds for part of the granola, then adding pumkin seeds as well.
