My 16 favorite fat sources and my latest big-ass salad. Going ketogenic has made me home in on my

fat sources even more than before. This is an essential practice for anyone seriously pursuing

a ketogenic diet. As fat will comprise the majority of your calories, you need to maximize the

nutrition you'll obtain maximize the nutrition you'll

some convenience. So what are my favorite fat sources? How do I use them? What do I find so appealing?

enduring utility of a good bottle of

extra virgin olive oil. Even though EVOO is quite robust in the face of high heat, I still prefer

using it in certain dressings and for lightly grilling fish, just to preserve the delicate flavor.

Go to a farmer's market and buy the local olive oil that tastes best to you.
