I'm a Paleo enthusiast! And a certified personal trainer. I would not suggest adding "good" fats to your diet, as in adding it by supplementation, it doesn't work that way. You have to be careful that your whole nutrition plan is spot on.
You should consume good fats. Yes, coconut oil, olive oil, are good. Optimal fats from protein are organic GRASS FED, FREE Range meats. You can get good fats from nuts and seeds, and veggies like avacados.
The best butter to consume is butter made from grass fed cows, and preferably from RAW milk. But there are only a few states that allow consumption of raw milk.
Grass fed is really important. Cows were made to consume grass not grain filled with foreign stuff in it.
I eat lots of meat (beef, bison, chicken, turkey, and fish)
TONS of veggies
and the only fruit I consume are berries, and grapefruit, and occasionally an apple. I occasionally make buckwheat pancakes, and steel cut oats. Water and a Big variety of herbal teas (unsweetened)
I am very low carb also. I don't even eat dairy at all. If I need a "milk" it's unsweetened coconut or almond milk.
