Perhaps the greatest gift I received from LCHF is that I have formed a better relationship with my hunger. For once in my life, I understand how my hunger hormones are supposed to behave. The key to this understanding was removing the foods that were corrupting the performance of my hormones.
I agree that the concept of listening to what your ghrelin and leptin is signaling is a bit alien, especially for someone who is used to being hungry all the time (because of processed food interference) but with time and practice those hormones can be rehab’ed. When I think about it in ancestral terms, our digestive system and all their complex hormones are a product of a million+ years of evolution and I doubt we would have survived this long if the hormonal communication had not been perfected.
Speaking of ancestors, they had no scales for weighing foods, had no supplements and had no way of tracking macros or counting calories, yet they thrived and obesity was rare. Their bodies told them what they needed via cravings. Low on electrolytes? They craved salt. Low on iodine? They craved red meat… etc.
Fat adapation was one of my many eureka moments in keto. The first time I went more than a day without food, it was a shocker that I wasn’t cranky or even hungry in the slightest. My energy was through the roof and consistent so it was obvious that energy was coming from somewhere since I was not eating it. It was as if my ghrelin and leptin went on vacation. I had little appetite and I became full with abnormally small amounts of food. So I went with it… I listened to those hormones and simply ate the amounts that I found satisfying and I lost weight faster than I ever had in my life.
I honestly believe that almost everyone has the biological ability to communicate properly with their hormones. It’s encoded in our DNA. It’s the lies that our brains tell us that we need to be suspicious about. The only way to undo the brainwashing caused by processed foods is to remove them from our diet and practice listening and responding to our hormones.
I will submit an escape clause to my belief: if someone has a defective pituitary gland, hormonal signaling may be wonky.
