No, I’m saying we don’t need to count calories, because our appetite hormones will take care of setting our appetite at the proper level. Unless our hormonal system is completely broken, of course.
Before this whole argument gets rehashed yet again, let me stress that no one is denying the validity of the Second Law of Thermondynamics, we are simply saying that intentionally cutting calories is not a productive way to work with the human body. Of course if you lose fat it means you ate less energy than you expended, we’re simply saying that you ate less because your body was in weight loss mode, which is the opposite of saying that you forced your body into weight loss mode by cutting calories. The latter situation doesn’t usually work for very long, because the body reacts by cutting energy expenditure to match intake.
I don’t know all the mechanisms, but weight and body composition are pretty tightly regulated; ketosis and fatty acid metabolism are by no means the full story.
There are probably ways I could force my body to shed more fat, but why would I want to? I’ve reversed my metabolic dysfunction, my fatigue syndrome is in abeyance, I can wipe my butt, I can climb up and down stairs, I can get down on the floor and get back up without having to plan for half an hour how to achieve that. And in the process, my waistline shrank by over four inches and I reached my Phinney weight. Trying to go any further would involve a lot of hard work I’m not interested in doing.
Our body typically stops using our fat stores for fuel when the excess stored fat has all been shed.
Now, in the case of Phinney’s imaginary patient, that happened when her body fat reached around 22% (which is supposed to be average for women). Mine happened at a far greater fat percentage, but who am I to argue with my body?
It doesn’t seem to be, in my experience. I have more energy now, at four years into this way of eating, than I did before embarking on a ketogenic diet. Keto would probably have given me even more energy, but a flu-type virus I contracted in October 2006 left me with a type of chronic fatigue syndrome. So while I don’t experience the great energy levels people talk about on these forums, keto has brought me up to feeling like my pre-2006 normal. For me, no longer having to rest up for two or three days after exerting myself (say, to mow the lawn) is simply wonderful. So no complaints here.
