Thank you - I adjusted my post to mention that as the post is my thoughts based on the quote only.
I am happy that I give you reason to self reflect - I write about these topics based on my current environment and self reflection.@the-one-true-dan Aww - you are right - compromise can also be a form of negotiation but based on the quote I focussed on the part of the definition that causes self-defeat.

In the situation re. healthy eating if one does not only make plans but has been eating healthily for a period of time like you suggested - then cheating or compromising every so often is actually a good thing indeed.
