Blame that link on early morning with an iPad..such a pain to copy links but I'm also too lazy to go on the desktop computer.

It is the straight forward waist half height ratio as in these two big British studies: http://forum.lowcarber.org/showthread.php?t=442331 so at 5'2" anything under 31" correlates with "being healthy".

Also Ted Naiman uses W:H, but again Diet Doctor complicates his simple answer by making a table. https://www.dietdoctor.com/simple-w...lth-measurement

Protein Amount:
Phinney and Volek at Virta use yet another formula, Reference Weight. But then they give a simple chart with wide leeway for amount of protein. https://blog.virtahealth.com/how-much-protein-on-keto/ You shouldn't have to force feed protein on Zero Carb, but then they don't count calories.

I'm OK with this chart, it pretty much tracks what was in NANY, that was my start point with Dr. Westman. I have tried cutting down protein a number of times and never felt satisfied. So this chart, or carnivore diet, or Ted Naiman's protein leverage/P:E formula all equate to an amount of protein that is filling and makes me feel good.
