amadeus,
your "proof" in the form of those two links at the beginning of this thread is in no way an affirmation of any benefits from fasting. The first link is a link to a company that seems to make faucets and the second link does not pose any scientifically-backed evidence at all (except for the "biochemistry of fasting" which sites sources that are from 1986, much too outdated to be any kind of proof).
When you fast you are not only losing "unhealthy tissue" as you have described, but also vast amounts of muscle mass, which is essentially slowing your metabolism down. It is in the bodies best interest, in long periods of food deprivation to conserve all the fat that it can. It does this by causing the person in question to become less active, in order to conserve energy expenditure, and it begins to break down the fibres within skeletal and cardiac (your heart) muscle - if you arent moving as much, you dont need as many muscles anymore. The body slows fat oxidation in order to save the energy in fat so that it can keep the body alive as long as possible (your body has no way of knowing how long this period of fasting is going on for, and the more you fast, the more efficient this fat-saving, muscle-wasting response will kick in). When you begin to eat again, not only are you most likely going to binge a little bit more than you should (because your body has no way of knowing when this food availability period is going to last, and therefore drives you to eat as much as possible to stock the fat stores that were previously depleted and to create new fat stores/cells). In addition to eating more, you are not going to be burning these calories as efficiently as you did before, due to your decreased amount of muscle and, therefore, decreases metabolic rate, and this will further encourage the storage of more fat.
While i understand fasting as a way of raising social awareness, or money for causes that you feel strongly about, this is in now way a solution to weightloss, or health problems. Fasting to lose weight can also be recognized by the names "anorexia, bulimia or yoyo-dieting". Please do not fast with the expectations that you will emerge from this fast, with a healthy, permanently leaner body. In order to produce lasting weight loss you must make the appropriate lifestyle changes and understand that it took you a long time to put on this excess weight and, therefore, will not take you 3 weeks (or however long) to lose it all. understand that there is no quick solution to weight loss and healthy eating, and that gradual changes to your diet and activity levels are much much better for your body than simply starving it for various periods of time.
