Well I can vouch for eggs. Ever since I added eggs and olive oil in my diet I'm feeling and looking better. Libido much better to. However with fats I believe that the key is balance. If you increase saturated fats you also need to increase monounsaturated (olive oil) and polyunsaturated (fish oil)... same thing for if you add lots of fish oil in your diet you must also increase the other types.
For example I have protein pancakes once or twice a day...basically
1 scoop of protein
3-4 whole eggs
1 tablespoon of olive oil
And with that I take a serving of FLAMEOUT and it is cooked in coconut oil
