I, too, find many benefits by being ketogenic in my WOE. Am I 100% in ketosis (levels at or above 0.5mml)? No, and I don't sweat it. The objective for me is to stay in or close to burning fat as my primary fuel. Should I lapse into burning glucose due to some higher carb intake, I know I'm close enough to get back into fat primary very quickly. Yes, agree with many observations that there have been many discussions about ketosis, and I far prefer endogenous ketones for what I'm trying to accomplish, which is fat burning as my primary fuel. Adding exogenous ketones, as correctly pointed out, will simply substitute an outside fuel rather than my onboard body fat. I always want my body fat to be the primary source for my metabolic fuel.
