Just remember that not all fats are bad...olives are one of the "good guys"...like avocado and nuts. Moderation, yes...but you don't want to eliminate them entirely either.

Monounsaturated fats
Are liquid at room temperature and turn cloudy when kept in refrigerator.
Primary sources are plant oils like canola oil, peanut oil, and olive oil. Other good sources are avocados; nuts such as almonds, hazelnuts, and pecans; and seeds such as pumpkin and sesame seeds.
People following traditional Mediterranean diets, which are very high in foods containing monounsaturated fats like olive oil, tend to have lower risk of cardiovascular disease.
Polyunsaturated fats
Are liquid at room temperatures as well as at cold temperatures
Primary sources are sunflower, corn, soybean, and flaxseed oils, and also foods such as walnuts, flax seeds, and fish.
This fat family includes the Omega-3 group of fatty acids, which are anti-inflammatory and your body can’t make. In addtion, Omega-3 fats are found in very few foods.
It's the saturated fats and trans fats that you want to stay away from, not these healthy fats.
