Perhaps a simple illustration will help.
Imagine that the water system of your body (in many ways a much simpler system than the energy system) suddenly went haywire in such a way that you never got the urge to urinate and you never got thirsty. Or that you constantly had the urge to urinate and were constantly thirsty. Imagine that you were forced then to consciously keep track of exactly how much sweating you did during the day (factoring in temperature and relative humidity) and how much urine you eliminated (by measuring it exactly) and then had to formulate to the milliliter how much water to take in to match what you put out day-to-day. Imagine that if you got it wrong, that water would be stored in a dangerous way inside your body somewhere over time in a way that made it difficult to get to later, or that a series of miscalculations that led to a shortage would, over time, grind you to a halt. How easy would it be for you to keep track of all that consciously and to decide how to act on it moment to moment?
Fortunately, we don't have to do that. For must of us, the body's water system is working properly, and the system isn't that touchy, sensitive, and critical on that level. We have thirst and a bladder and a nervous system and hormones that pretty much keep track of the water inside us and take care of things automatically, and we are able to read our signals and react accordingly under most normal circumstances. And even when we get it wrong, the body helps tip us off and the excess water is eventually released easily enough or the water shortages get solved in short measure with a few gulps.
The energy system in some humans is almost as efficient as that. It is mostly automatic in a way that they don't have to think about it. They get hungry when they need calories, they crave the correct foods, and their bodies are efficient at getting nutrients from what they eat and then getting rid of what is not needed. That is great. We should all be happy for the people like that. Good for them. But when a human body develops certain problems and sicknesses, that very complicated system can go awry. When people get overly tired and sleepy and stressed and panicked, some of them have bodies that interpret that as a lack of energy and then send constant, loud signals demanding high-energy foods. The body may develop cravings for certain nutrients but then isn't able to clearly get a message to the conscious mind about what exactly, and the wrong foods are eaten. Then the body screams out for the person to try some other food, or to simply eat more, to see if it can get what it needs from that. Over and over. Then some bodies go into a panic mode and start storing when they should be eliminating. When it all gets out of whack far enough, a person finds himself in a position where he can't trust any of the messages being sent him from his body. It is all short-circuited. Then he cannot, like the humans without that problem, live his life normally at all. No one has the mental and emotional energy, or the ability, to completely ignore every signal from his own body. If he did, he wouldn't eat at all, or he would eat all the time, or he would have no idea when, what, or in what amount to eat, since nothing quiets the screams. And measuring water to the milliliter based on sweat and urine would be infinitely simpler than what it would take to keep track of every nutrient the body needs and what it would take to meet the energy needs moment-to-moment all day long consciously.
A person whose body is not having that problem can decide to eat ice-cream and not worry. His body can handle it and will adjust the messages it sends later accordingly. No willpower involved or needed. And willpower alone is enough for him if an occasional errant message is received. He ignores it awhile and it goes away. His body isn't sending him completely haywire signals loudly all day long that would take truck-loads of extra-human willpower to ignore or to reinterpret. Someone who has not experienced what it is like to live in that kind of malfunctioning body has no idea what it is like and may assume that all humans have as efficient and as easy-to-manage an energy system as his body has. I cut those people slack when they don't understand the tribulations of those with medical conditions that cause energy problems. There is no way they can understand what it is like. Their ignorance is understandable. If they had any idea how stupid they sound telling other people what they need to do to manage their energy system, when it is nothing like theirs, they would know to be embarrassed by their own words. But they don't know. So just ignore them. Or laugh. Or stick your tongue out at them when they aren't looking. They aren't idiots any more than we are. Just ignorant. How could they possibly understand that not everyone is like them?
A low-carb diet, especially if it has a temporary drastic phase to it, has been shown, anecdotally, to be a useful tool for some for resetting their bodies' communication system as it relates to energy intake. It works for some. Not for others. But anyone who has to consciously decide what to eat and how much and when, because his body's energy-communication system has been damaged or circumvented internally, needs to make sure he is careful and balanced and getting the right nutrients long-term if he decides to consciously do things to lose weight. That is true of any diet in which the conscious mind has to play a large role in overruling the messages from within, not just the various low-carb diets.
In my opinion.
Did you ever have a professor who assigned a somewhat lengthy essay to be read...and somewhere, usually about three-quarters through the essay, there was a sentence claiming that if you've read this far the prof would buy you a beer? I'm afraid that wasn't the case here. Now where is that chunky monkey?
