REASONS FOR BAD BREATH DURING FASTING
 fasting involves the willing abstinence or reduction of some or all food, drink or both for a period of time. Most individuals who engage in fasting usually engage in dry fast; that is, total abstinence of food for certain hours of the day. Others may abstain for days depending on the type of fast. Religion such as Christianity, Islam, Judaism, Hindu etc. all indulge in this activity. The activity is not geared towards ketosis; to them it is a spiritual exercise which every member must partake for either spiritual cleansing, enlightenment, or to offer supplication to the almighty. Religion such as Christianity gives its members the freewill to decide when to indulge in the activity, usually at any time of their choice. But there are general times where all Christians may converge depending on their sub-group (Catholics, Pentecostals, Methodists etc.) to engage in a general fast. Others such as Islam generally engage in a fast at specific times of the year usually twice as the case may be determined by Mecca.
Engaging in fasting involves keeping the mouth dry from food. When the mouth is dry, the probability of you experiencing bad breath is higher. This is because the mouth is not moist enough to remain neat. The saliva has an important role in the mouth, that is, to keep the mouth rinsed and moist, when the it is dry.
 During fasting, individuals are usually engaged in much conversations; this advertently leads to bad breath. The conversation may not be with humans but with God as they believe. The conversation results through prayer and supplication of their needs and wants. When a person has not eaten and engage in much talking, it dries the mouth and this leads to mouth odor. Bad breath is not planned for, it is as a result of certain actions conscious and unconscious which people take.
 Just like ketogenic dieting, fasting also burns down excess fat in the body. People who engage in ketosis usually experience bad breath, due to the fact that it is a sign that the ketosis is working. When the body burns fats, the waste is removed from the body in form of urine, sweat and breath. So during fasting one may experience bad breath due to the fact that the liver is conditioned to produce ketones which aid in the breakdown of carbohydrate.
 have you ever noticed that after brushing in the morning and one does not take in food, as he/she regularly does, over a while you begin to experience bad odor from the mouth. This is because, the mouth is used to taking food after brushing. The body has been programmed that way. So not taking in food substances to keep the mouth warm, leads to experiencing bad breath during period of fast.
 During fast, some individuals who are not engaged in praying, usually stay silent or closes their mouth. When the mouth is over closed such that air cannot penetrate into it, this leads to bad breath during fasting. Just like when you sleep at night or during the day and wake up to perceive that foul odor, it’s the same. It is however advised, that the mouth should be opened to receive air from time to time; so that the bad breath may be exchanged with air.
 During fasting some individuals who are pious may not feel the need to bring water in contact with their mouth, hence they do not brush their teeth. Needless to say, that not brushing their teeth obviously leads to experiencing bad breath. Bacterias and Germs which have stayed overnight needs to be removed through brushing the teeth and tongue effectively. Also the food particles of the previous day also needs to be expelled from the mouth. Those particles decay and grow stale, leaving the mouth dirty and smelling. However, brushing daily is very important.
