Whole eggs, avocado, nuts of various kinds, natural peanut butter or other natural nut butter, olives/olive oil, seeds of various kinds, fatty fishes (salmon), various cheeses. Use everything in moderation, since fatty foods add up in calories quickly, as you saw in the peanut nutritional info above. Always mix the fat with protein if it isn't already mixed.
I wanted to add that I agree with a lot of the points red head made in his longer post above.
Also, if by "low carb," you are talking about a keto diet, be aware that it takes ~3 weeks for your body to fully adapt to that particular diet. So you need to test it for a while to get the full effect.
Ok. Cool that also. So a clean diet is basically all natural nothing processed or nothing with man made added things right?
