Oily face and pimples

I have been eating oily and fatty foods lately.I know it's not good for my health but what can I do,it is just so yummy and tempting.And also with this,I notice that I have oily face and have some big pimples on it.I guess I might need an acne treatment if it will continue to grow more and more.I do not like my face full of big pimples coz sometimes I could not control my self scratching it.Hope these pimples will be gone soon and I hope the soap that I am using now will help to eliminate these pimples.
