Aren't cravings induced by memories of previous pleasures? Somehow like an alcoholic or a drug addict is craving to drink alcoholic beverages or taking the drug again after weaning. We know that processed and neolithic foods are addictive, so it must be analogous.
No! I'm sure that desire for pleasure
could be the cause for some carb cravings, but I'd only investigate that cause after I had ruled out problems with carb metabolism.
In my case, I was producing plenty of insulin, however metabolic problems prevented me from utilizing blood sugar for energy at the cellular level via cellular respiration. Therefore, despite having eating sufficient food from a caloric standpoint, I was ravenously hungry as if I had not eaten at all. The cycle often leads to obesity, because the excess insulin allows the body to store the excess blood sugar as body fat. Clinical symptoms didn't start for me until I was in my mid-forties, but the cravings were there all along and got worse as time passed.
There were no memories of previous pleasures, unless you call symptoms like unrelenting hunger, drowsiness, and malaise pleasurable. Imagine yourself counseling a person with ravenous cravings due to metabolic problems, and you discount the plausible reasons for their symptoms and liken them to an addict! You would be doing nothing to help their health, and you would be adding shame to their perplexity.
If cellular respiration is faulty (called insulin resistance), low-carb eating allows the cellular energy short-circuit to be alleviated because, in the absence of abundant blood sugar, cellular fermentation occurs, allowing the cells to use fats for energy instead of sugars. The switch from cellular respiration (glucose as energy) and cellular fermentation (lipids as energy) happens naturally. The by-product of cellular fermentation is ketones, so this style of eating is often referred to as a ketogenic diet.
Since fat-burning is one of the body's normal energy alternatives, ketogenic eating does not go against Mother Nature. Counting protein, fat, and carb intakes is only needed until one gets used to fixing up low-carb meals. We are engineering the meal, not the food. For example, blood tests have shown me that I can eat up to 10g of carbs at one meal without getting lingering blood sugar spikes, so I eat up to that limit or less per meal. Current blood tests show that I have normal A1C and blood glucose levels, so I can say I reversed diabetes by eating this way. The original poster, panacea, reported no diabetes or obesity, but I applaud him for responding to the first symptom (carb craving) rather than wait until he is older and has many symptoms.
I can't address the causes of addiction to substances like alcohol and drugs, but I'm sure the addiction to each has a biochemical component; if it were possible to instantly shut off the faulty biochemistry, the addiction would disappear in that instant. With dietary carb-cravings, low-carb eating instantly fixes the biochemical component using a normal metabolic pathway. Whatever the downside of staying in ketosis, the upside wins.
