TBH, I don't know what my percentage of fat is. I suspect it's pretty high, though, since my carb intake is pretty low. The last time I figured it I just figured the amount in grams. I was exclusively nursing a 10 mo. old (he still hadn't started eating solids). I was easily eating 200g fat a day, probably more. But I don't know how that figured into percentage.
I LOVE mayo. I make our own with olive oil and a little avocado oil. I use it whenever I can. I use plenty on my burgers (no bun, thanks), or with my boiled eggs. I make salads with it.
When we have burgers, I also make caramelized onions with lots of coconut oil. And we have avocados, too. (I love that meal. I feel so good afterward. I bet it's all the fats).
I add ghee to anything I can (if you can't eat ghee, another fat would work, like tallow, coconut oil, bacon grease). If we have potatoes, I use an equal amount of fat to my small serving of potatoes. If we have a stew-type dish (like chili, curry, whatever), I add a large dollop or two of ghee to my serving. I sautee veggies in plenty of coconut oil and olive oil. We also love caramelized onions, and that's high fat (the way I make them, anyway
As someone else said, smoothies are perfect for adding fat. I add raw eggs and coconut oil to mine, along with coconut milk and/or coconut cream concentrate. And no sweetener is necessary (honestly, it makes the smoothie too sweet for me).
I also like to make coconut balls and nut balls. Nut balls have to be kept in the fridge, though (at least the ones I made). I like the coconut balls, because unless it's super warm they can be kept at room temp. I mix coconut cream concentrate, coconut oil, shredded coconut, a small amount of honey and/or stevia (they'd be good with no sweetener at all, too), and vanilla. Sometimes I add ground chia seeds, too. These make a great snack!
I also eat a fair amount of eggs.
When I do eat a hot cereal (buckwheat) in the morning, I add beaten eggs, and also add plenty of ghee or coconut oil.
My favorited breakfast is refried black beans (and guess what, I use a lot of ghee or tallow or coconut oil when I make them) with fried eggs.
I hope this helps some.
