Fasting is not good for everybody. Some people are weaker; they feel bad and nauseated without food, especially when it comes to children, those with eating disorders, elderly and anyone with overall bad health. It can be good for weight-loss and to clean the body from toxins, but that’s about it, doctors claim.
If you shiver when you skip a meal, fasting is not for you. Some people need less food than others and it comes easy for them to fast. How dangerous it depends on the overall health: blood count, weight, metabolism, even mental state. If you do decide to try fasting to detox the body or for religious reasons, make sure to go get checked by a doctor often. Some medical workers even say that fasting is not good for anything except to lose weight.
Whatever you decide, make sure you not to starve yourself for too long because your body will suffer, also your mind. A fast shouldn’t be that hard if done properly, but your body could burn muscles instead of fat if you fast for too long. Moderation is the key.
