I try to balance my fats with all different types, including saturated fats, monounsaturated fats, and omega-3's. I try to stay away from omega-6 fats because they are pro-inflammatory and can lead to GI troubles, joint problems, and bad allergies in the spring. That said, I'm currently exploring certain omega-6's after my workouts to promote muscle building, but that's more complicated than it needs to be.
Basically, I do a lot of cooking in virgin coconut oil and olive oil, eat whole eggs, have fish and grass-fed beef as often as possible, and on top of that take fish oil. I'm also a big fan of cheeses and chevre.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
