I am going to have to respectfully disagree. All of the excuses you mentioned can plainly be summed up as a lack of commitment. I, too, have heard all the dietary jargon & ever changing suggestions about what is “healthy.” The bottom line is, most people who attempt the Keto WOE are doing so because their SAD has failed them in one way or another, whether it be physically, mentally or emotionally, & are seeking something better. That alone should be enough evidence to understand that they have been grossly misinformed & no longer need to cling to certain ideologies.
If a person chooses to try the Keto WOE then they shouldn’t cheat themselves by half assing it. It’s a pretty basic set of rules. Follow them or don’t but, make up your mind one way or the other.
It’s a pretty black & white matter to me.
