What creates weight undoes them, I mean our metabolic functioning. Dieting is an attempt to adjust weight that sets up a fight with our bodies, rather than working with the way they actually work. It's too partial and inflexible a method of taking on what is an extremely versatile, multifarious and comprehensive set of systems.
The basis of dieting is eating is consciously controlled because that's the part we are most aware of. It is an important part, yes but by no means the whole or even most of it. The extent to which dieting fails suggests the size of its involvement.
If that was right, we'd change our eating by changing our decisions, we wouldn't need diet plans at all. All the planning and scheming is in place of what's already working that out without direct conscious in put.
The purpose of eating is to refuel and provide nutrients the body cannot make itself. For this it needs to know how much energy each part and therefore the body needs as a whole. That information must come from the parts and systems of the body themselves. If you look at anatomy, you can see they are all connected by nerves to the nervous system. This goes both ways but information on what is needed must travel up to the brain which becomes both your perception of hunger and what you need to make up that hunger-nutrient needs.
The purpose of your brain is to carry out these instruction, it seems to contain the 'switches' activated by and part of these information pathways.Your conscious mind takes into account environmental factors, such as availability, personal preferences, cost etc.,
Hunger and appetite cannot be generated solely or even mostly by the conscious mind a crucial mistake of the diet hypothesis. Our eating habits are not just habit, they are part of our history, experience and culture. By using food to respond to hunger our body builds up an internal profile of what works well to satisfy our needs. Dieting throws that aside and sets the body and mind into confusion.
Its a bit like changing job and moving home all at once. You have more or less the same as you had before, but its not exactly the same and it can take a while for your mind to adjust to what has been suitable for you and that you have worked with and adapted to. It's not about the capacity of your body to shape itself singularly around things it is used to, not a bovine refusal to change.
It has to re configure that to changes and that doesn't take into account the attack on its ability to survive-through calorie restriction.
The body measures your energy needs and matches it to your intake it counts calories for you, that's another reason its hard to stick to diets, you are disrupting and messing up its accurate calculations with your crude and inflexible ones.
You are duplicating a process designed to do what you are doing badly and stopping it from working to the best of its ability. Your body's signals build to cravings when you try to cheat them for the purposes of starvation. Succumbing and responding to these is not 'rebellious' it is almost inevitable. It is making up for the loss you created, isn't that initial denial 'rebellion'?
Boredom is a form of tiredness your brain and/or body are going short of energy so it is part of your loss of will, you are using it up. That article actually indicates that your will has a basis in energy, namely glucose and when that is depleted your ability falls and when replenished, rises again!
If so no wonder you crave high calorie/ sugar foods, also due to your body wanting to replenish its lost 'fuel' as quickly and as efficiently as possible, before you get any more funny ideas. Well, can you blame it? This is the source of a lot of eating disordered behaviour, the lack of trust that you will meet its needs. Like a poor person snatching at unexpected bounty, it develops a legacy of insecurity as you keep messing it around and can adjust your appetites accordingly around this.
And don't believe you 'return' to your old eating habits, which refers mostly to the amount you formerly ate. Why would you if you've lost weight and proven you can eat less? You've done the hard part and adjusted to that, some diets last more than a year that's before any rebound.
In the end your body plays the long game, it can wait, for any chink any snatch of light and it's in there pressing the buttons most likely to usurp your efforts or bombarding you with more than you can handle.
Eventually, everything just gangs up on you. The body just keeps adding and adding and even if you manage to dodge these obstacles over and over again, they just keep coming and/or repeating eventually something will get to most people or the effort of endlessly trying to outwit or adapt to each hurdle will become too much.
Some people just simply burn out, it's not one thing specifically, it's everything, it getting to the last straw.
It's like trying to stay awake for ever, eventually your body, after numerous attempts to thwart your intent just takes over and drowns your fading will in its own.
