Explanation / Answer

There are two types of fats one us saturated fatty acid and another one is unsaturated fatty acids. The bad fats are saturated fatty acids. We keep eating fats because our all cells have cell membrane that is made up of fatty acids. It is necessary to eat some amount of fats as our cells need them.

In order to decrease daily consumption of fats you can consume olive oil that is rich in poly unsaturated fatty acids.

So, you should limit the food intake that has higher amounts of saturated fatty acids.
