And how do we all know this? Truth is, we don't. If we know so much about how LC diets work how come so many of us stall? Just because I've lost 76 pounds doesn't mean I know how to lose the next fourteen.

YMMV doesn't only apply to LC diets it applies to all diets. One of my favorite studies was done by Phinney and Volek of "0.8 ketones is magic" fame. http://www.biomedcentral.com/conten...3-7075-1-13.pdf Figure 3 shows that for men, 4 of 15 favor a low fat diet and for women, 5 of 13 favor a low fat diet. Not only that but when they switched the subjects from one diet to another the results varied depending on the sequence of diets.

So before I declare my wife "just doesn't know what she's talking about" I admit to myself that there isn't a whole lot of Clarity with keto diets.

Of course you're right, inflammabl. I'm not sure LC is "working" for me right now as a weight-loss diet. Definitely not fast weight loss!

However, I know myself. That self isn't willing to give up the LC pleasures I've learned to enjoy, eg. HWC in my coffee, meat with the fat attached, and butter on my broccoli. Low-fat is low-fun, as far as I'm concerned, although I've successfully lost weight (poundage anyway) on every diet there is.

At the same time, I'm trying not to fuss too much about ketones and calories and protein grams. Just steady as she goes. It keeps me out of cupcakes and tortilla chips.
