Listen buddy,
Three very well informed martial artists have disagreed with what you are doing and stated that you are going to do harm to your own body. I have just made this number four. If so many people disagree, perhaps you are doing something wrong.
I am almost certain that you are doing is detrimental to not only your training but also your health. There is no point in doing a "transition period" between eating unhealthily to eating healthily. Start eating healthily TODAY. Detox diets and fasts are COMPLETE BULL****. You seriously need to do some more research on what is healthy. Not only that but you are more likely to go back to your bad eating habits *after* a fast than if you just start eating healthily today. The concept of fasting to drain the toxins out of your body is misguided rubbish.
What you are saying about toxins is completely misguided. Toxins in our bodies are constantly being processed by our liver and kidneys. A trace amount leave the body via other pathways. For example, no alcohol will be in your body 48 hours after drinking. Only heavy metals such as lead and mercury stay in our bodies for longer periods of time and those DO NOT leave our bodies during our lifetimes.
In order to become stronger you have to eat correctly and exercise 4 days a week for 1/2 to 1 hours each of those days. Eating right means getting protein, carbohydrates, vitamins, minerals, water, sugars, fats and oils. YES THAT'S RIGHT, your body NEEDS a certain amount of FAT in order to function correctly. Low body fat can lead to, among other things, STERILITY! You do not want this do you?
If you only drink water for a couple of days, you will be lacking in magnesium and calcuim. As a result, your muscles and nervous system will MALFUNCTION. You will experience what are generally called MUSCLE SPASMS and MUSCLE CRAMPS. This is because calcium is necessary for the process of muscle contraction and magnesium is necessary for the process of muscle relaxation. Lack of protein will decrease your muscle mass, making your strikes and other techniques weaker. Lack of vitamins including Vitamin C can lead to many ailments including Scurvey. Lack of carbohydrates, sugars, fats and oils will make you feel tired and decrease your ability to perform physical activity for a CONSIDERABLE period of time after the fast.
Furthermore, even if you ate correctly before an 18 hour training period, your muscles would be traumatised by the end of the training time. It is HIGLY likely you will injure yourself because you have not prepared physically for the training session and your muscles (especially after your fasting period) are not used to the trauma of such a high level of activity. If you spend several months ACTUALLY TRAINING (instead of fasting) increasing by 2-3 hours each month you could possibly do 18 hours of proper training exercise but only if you were super-fit (and I mean "RUN UP MOUNTAINS" kind of fit).
You are SIGNIFICANTLY better off spending 5 days in a week training 4 hours a day, with a 10-15 minute break between each hour. Even doing this, you negate many of the effects of your training by exerting your muscles without a proper rest period.
More importantly you should NOT have to prepare for a training session beyond some stretching and aerobic warmup. If you have to do something so rediculously difficult just to have ONE SINGLE training session, you cannot possibly train regularly. That is far more important than the extrenuous, dangerous activity you suggest.
The effects of feeling your mind clearing probably have nothing to do with your fast. You are probably inflicting this condition upon yourself, more of a mental control than anything else. Kind of like the placebo effect. Joint problems can only be overcome by light plyometric training with the correct nutrient intake to repair the tendons and ligament around the joint. Red meat is not bad for you if you prepare it correctly and don't over eat. Alcohol in excessive amounts is bad but in small amounts it is not harmful. (Not that I advise drinking)
If you train your techniques 4 DAYS A WEEK you will gain the muscle memory and body strength to be the best you can be. Perhaps in 15 years or so you will start to truly understand your martial art and how BEST to train for it.
