I strongly recommend binaural beats. It works extremely well.

I agree with what you say. I strongly promote the use of eastern philosophy, reality altering use of SAFE herbs, and meditation techniques. Particularly, the emphasized goal is to deal with ego and subconsciousness - to deal with separating one's self identity from the imposed expectations and judgments (i.e the material western world) and find a sense of inner peace and happiness. The want and desire of a material modern life often invoke anxiety and feelings of inadequacy. This is from a lifetime of built in subconscious cues influencing you to believe a certain reality and life (house, car, family, tv, boat, high paying job, suits, vacations, etc) is the only way to be happy, and that falling short of this will result in judgement of your character. This is a very standard definition of the ego, in that it is not what the world expects of you or imposes upon you- it IS what you perceive, distort, and occlude to be what you THINK you must do in order to gain their acceptance. Because of this many forms of neurosis take place in society. People react to what they perceive they must perform to obtain, and this can lead to stealing, lying, cheating, murder, depression, hostility, envy, vindication, negativity, and bitterness because of the conflict between the ego, self, subconcious, and outside material world. However, some people react to the material world and prosper in it, finding ways to display all the opposite traits, i.e. leadership, benevolence, selflessness, success, productivity, creativity, examples being famous scientists , etc. How can such a dichotomy exist. It is purely because of the individuals PERCEPTION and REACTION to dealing with the outside reality. Thus the ego is a neutral entity. However, the ego can represent the way the outside world perceives you and remembers you, i.e. famous people in history. Problems arise when the ego is sought to be preserved in a manner that is at conflict with the self identity and with the greater society in which a person is involved. In this sense, most depression and anxiety has a strong root in confusion and irrationality. This is why fasting, meditation, and herbs and philosophy and religion are so strongly needed to keep people looking inward. Without both a strong connection to self identity and a strong connection to the outside world many problems are open to occur.
However,
On the contrary I felt that my heart was in stress and body lacked energy and i was sleepy all the time. Finally i realized that it is better to use glucose and carbonates as energy source than ketones
Fasting is not meant to be a long term thing, and it is contraindicated for those with dangerous conditions. However, I also must emphasize that diets ARE important. Simply put, in this modern world, there are too many harmful chemicals in the food and water that affect your mental and cognitive powers. They are so strong they are capable of disturbing mental functioning and making meditation, mental, and spiritual development impossible. If you look at many average americans, irrationality, anger, pettiness, are rife. Look at how people behave in crisis like Hurricane Katrina. Conversely, look at how people behave in Japan during the Fukushima Earthquake. Many societies contain people who are much more controlled in their demeanor and temper. Foreign people see Americans as being extremely direct and quick tempered. The diet and culture are a strong reason for this behavior.
Worse yet, perhaps the worst. Heavy metals are a grave concern for mental health. The autism rate is sky-rocketing, and though the research is very divisive and entrenched against a root cause- there are still strong peer reviewed studies and particularly clinical studies showing that metal toxicity causes these problems. And of course, dental work, root canals, crowns, and fillings are a tremendous source of mercury. Of course the dentists, vehemently denies this, sound Environmental and Public Health Toxicology proves it strongly. You really owe what little security you have to the scientists who work for the EPA, NIH, CDC, etc.
A high carbohydrate, low fat diet, with very large amounts of vegetables and produce is essentially the baseline human diet, particularly in a traditional diet such as the Indian and Chinese diets. However, because of the severity of Western diseases and chronic conditions, water fasting is something that really must be considered as an option of last resort. And for some it can work, for others it cannot.
While a water fast does not promise much, a fruit fast is extremely powerful. Ultimately, if you have an autoimmune condition or cancer, and still have some reasonable digestion, a fruit fast offers you the most help. In my case I not only have Celiac's disease, I also cannot tolerate fruit very well, as I have blood sugar issues, and colitis. However, I am a few pounds overweight, and do have a healthy cardiovascular system, and experience fasting. For me a few initial water fasts are preferable, and future fasts would be with broth or fruit.
