Ketosis refers to acids in the body that are derived and used while in a state of low glucose in the blood. Because my body has been in a state of ketosis for the last 3 years, I feel qualified to speak about this lifestyle. I call it a lifestyle because it really is. It’s a lifestyle completely different from the lifestyle of a carboholic. Carboholics require food every other hour or so, it’s the law of glucose consumption, appetite follows glucose levels in the blood. It’s that simple, blood sugar levels rise and satiety sets in, releasing hormones controlling feel-good emotions influencing behavior, sometimes unrecognizable behavior. But, that usually happens when the blood sugars fall again after a couple hours releasing hormones of hunger, need and want. These hormones are completely different than the satiety hormones and have a much different effect on the body.
According to PubMed, on the subject of ketosis;
“Hunger and satiety are two important mechanisms involved in body weight regulation. Even though humans can regulate food intake by will, there are systems within the central nervous system (CNS) that regulate food intake and energy expenditure. This complex network, whose control center is spread over different brain areas, receives information from adipose tissue, the gastrointestinal tract (GIT), and from blood and peripheral sensory receptors. The actions of the brain’s hunger/satiety centers are influenced by nutrients, hormones and other signaling molecules. Ketone bodies are the major source of energy in the periods of fasting and/or carbohydrate shortage and might play a role in food intake control.”
They go on to say; “Glucose also exerts a hormonal-like action on neurons; electrophysiological recordings demonstrated, for example, that hypoglycemia activates growth hormone-releasing hormone (GHRH) neurons, suggesting a mechanistic link between low blood glucose levels and growth hormone release (Stanley et al., 2013).”
This is where carboholics cannot have the advantages that being in a state of nutritional ketosis has. Those who chose to live in a state of ketosis) aren’t controlled by their hormones, so they don’t have to follow any hunger cycle. They’re in full control of their hormones. With hormones being the primary driver of appetite (leptin), they influence your appetite more than anything and are able to alter your ability to discern whether you need to eat or not. It’s called leptin resistance and we’ll get deeper into that later.
This also means that these hormones are in control of your emotions, because of that. I know that it doesn’t sound like it’s that big of a deal, but it’s more important than you ever could imagine. As I explained in Why the addiction is so hard to break and it has to do with how your hormones control your actions without you realizing it.
First, let’s look at the state of ketosis, as explained in Wikipedia;
