I'm not quite sure how to respond to this.
First off, I agree we are all individuals and will respond differently to different things. It is up to us to find what works for us as unique individuals. This form of eating pattern is just one option. I am using this to help me determine if I want to eat because I actually need nutrition at that time or if I want to eat for some other reason. It may or may not work. It is just one option among many.
I have also found that LCHF works for me and my CBG readings.
I have never been a breakfast person, even as a child, and work in a job where getting a break to eat is rare, no matter what the legalities of this is. As a result, I have done what is now called intermittent fasting most of my life. After reading information about fasting by Dr Jason Fung and his use of it in helping patients with diabetes, I now occasionally fast for longer periods.

Since finding out that my sister and I have become the 3rd generation of thin, adult onset, diabetics type 2's, a diagnosis that almost doubles our all cause mortality* when compared to someone who is diagnosed as DT2 while over weight, I have been aggressively following my CBG's and working to get them down to what is considered normal.

I already fast, I already follow my CBG's, and my goal is a normal CBG which would result in a normal HgbA1c. The combination of using my meter to determine when to eat actually makes sense to me as a way to gradually lower my CBG readings. What I find most intriguing about this is that research that used this pattern of eating* found that people who were overweight lost weight while those that were lean maintained their weight.

Since I pay for my meter and strips out of pocket, I am well aware of the cost. What I don't understand is your comment, "Not everyone has or can afford a cgm! So a glucometer is still referred to rather than the cgm." Huh?
A glucometer is a machine. This machine measures capillary blood glucose, CBG, levels. What is a cgm and what is the point this statement is trying to make? It is confusing.
