Many people intensely dread missing even one meal. These folks usually are and have been so toxic that their bodies had been stashing uneliminated toxins in their fat for years. They are usually so addicted to caffeine, cigarettes, alcohol, and so forth, that when they had fasted, even briefly, their bodies were forced to dip into highly-polluted fat reserves while simultaneously the body begins withdrawal. People like this who try to fast experience highly unpleasant symptoms including headache, irritability, inability to think or concentrate, blurred vision, profound fatigue, aches, etc. Most of these symptoms come from low blood sugar, but combined with the toxins being released from fat and combined with going through multiple addictive withdrawals, the discomforts are more than most people are willing to tolerate. Fasting on juice is much more realistic for cases like this. It is little wonder that when a hygienist suggests a fast to improve health, this type of case asserts positively that fasting is quite impossible, they have tried it, it is absolutely terrible and know that they can't do it. This rejection is partly due to a cultural expectation (one reinforced by western medicine) that all unpleasant symptoms should be avoided or suppressed. To voluntarily experience unpleasant sensations such as those mentioned above is more than the ordinary timid person will subject themselves to, even in order to regain health. They will allow surgery, drugs with violent and dangerous side effects, painful and invasive testing procedures and radiation--all unpleasant and sometimes extremely uncomfortable. These therapies are accepted because someone else with authority is doing it to them. And, they have been told that it they don't submit they will not ever feel better and probably will die in the near future. Also people think that they have no alternative, that the expert in front of them knows what is best, so they feel relieved to have been relieved of the responsibility for their own condition and its treatment.
