I'm not sure which idea of yours I think is the worst. Maybe skipping breakfast. It is natural to be hungry first thing in the morning. You probabaly haven't eaten for 10-12 hours. All this time you body is using energy. And no, most of that energy is not spent breaking down "toxic" cooked food. Most of that energy, especially when sleeping, is simply your body keeping itself alive. You brain needs calories. Your heart needs calories. Everything needs energy to maintain itself, even when you are in a resting state. So during those 10-12 hours when you haven't ingested food, but have still been using energy, your body has been tapping its stored energy reserves. Most of this energy comes from stored carbohydrates, in the form of glycogen. Some will come from fat. And some will come from protein. But the bottom line is when you wake up, your energy stores have been depleted, and need replenishing. Ideally, you will want some simple sugars such as fruit (limited amounts though) and mainly complex starches like oatmeal for example.
Second dumb idea: food doesn't give you energy. That is exactly what food is. It is energy, stored in a chemcical for in the various bonds within the molecule's that make up the substance. However, if you feel chronically tired, there may be more at work than simply a lack of calories. You may be getting enough calories, but are unable to matebolize these things due to a lack of essential vitamins or minerals. B-vitamin deficiencies and iron deficieny are common causes of this. But blood tests are needed to detect these problems. Don't self diagnose yourself - you will probabaly do more harm than good.
There have been studies that show that a moderate calorie reduction in healthy people has lead to longer life. This is primarily due to a reduction in free radicals. Free radicals are formed when molecules are broken down, and they are thought to be the cause of aging. Hence, the thinking is that by slightly reducing the amount of food you eat, you can slow the aging process. However, you have to make suer that you are still getting the nutrients and calories your body needs. As a runner, those needs will be higher than those of normal people.
Another note (to barefoot runner): you sound like you could be aneorexic, and/or have some kind of eating disorder. I say this for four reasons. You say that the body doesn't need food for energy. It does. You also eliminate major food groups from your diet. This is one of the warning signs of aneorexia nervosa. You also don't eat a lot. Another sign. And the fourth reason, and perhaps most worrying, is that you say that by fasting and undereating you feel in control. This is classic aneorexia - people feel that they need something in their lives to control, since there are some many uncontrolables, and so they choose to control their food. Because they can.
Next - there is no vital life force in food. This sounds like ridiculous, superstitious, new age mumbo jumbo. What there is in food is calories and nutrients. Your body needs both. And different foods will supply different nutrients.
There is a worrysome lack of vital nutrients in the food you have suggested for a diet. You lack animal products. Not only are complete proteins found in animal products, but many other vitamins and minerals that the body needs to survive are found in meat and milk etc. The few protein sources that you have given (beans and nuts) are incomplete proteins, meaning that they do not contain all the essential amino acids (the builfing blocks of protein that the body requires. You will be deficient and run into problems.
Another idea of yours which has absolutely no scientific basis is that by cooking food, you are somehow poisoning the food. I really don't follow this. If you would like to provide some study or anything that proves that cooking food turns it into a poison, I would be happy to believe you.
Also, if you feel thirsty after a meal, it is not because you have poisoned yourself with the food, it is probabaly because you have eaten salty food, whihc stimulates that body's thirst response.
I am getting slightly tired of responding to the amount of bs that is being touted here. So, in response to the intial poster's question, I suggest that you either see a nutritionalist or read some literature on the subject. You will get some good scientific facts that may help you solve you problem. And you will avoid the harmful crap that some people like to belive in.
