Confused about this? question about fasting

Confused about this? question about fasting?
i wanted to fast for a lil but i heard that ketoacidosis can occure if u fast. so if a person fasts for three days ur body panics and breaks down fats and protiens? from where? muscles? body fat? is this really unhealthy? wikipedia definition: Ketoacidosis is a type of metabolic acidosis which is caused by high concentrations of ketone bodies, formed by the deamination of amino acids, and the breakdown of fatty acids. This is most common in untreated type 1 diabetes mellitus, when the liver breaks down fat and proteins in response to a perceived need for respiratory substrate. It can also occur with people undergoing hunger strikes, fasting over 3 days, or people starving to death as the body is forced to break down fat for sustenance due to their lack of outside nutrition. Ketoacidosis can be smelled on a person's breath. It is often described as smelling like fruit or paint thinner Ketoacidosis should not be confused with ketosis

if you fast, your body needs certain nutrients to support basic life functions. it must get the nutrients from somewhere so it will turn to muscle.. MUSCLE FIRST, THEN FAT. this is because muscle is easier for the body to break down to get amino acids that it needs to survive. it can place the amino acids where they are needed, and use them as caloric fuel to carry on life functions. the body will also break down some fats for the same purpose, but it prefers muscle to fat. when you are done fasting, you have lost muscle mass and fat, and you have brought your metabolism to a halt. when you resume eating, your metabolism will be slower than before, and with the reduced muscle tissue, you will not be burning as many calories throughout the day. this is why fasting to lose weight is the worst approach you can take.

Yes, it's extremely unhealthy to starve yourself. Besides which, it doesn't help with the dieting at all, because if you do go through periods of starving your body, it will simply store more fat when you ARE eating in order to get through these periods of "famine". Your muscles will be the first to go, because muscle tissue needs a steady influx of nutrients to maintain itself. Then stores of fat will be used. Basically, your body starts cannibalising itself. In any case, it is a very unhealthy, and in the long term inefficient, way to lose weight. Not to mention, prolonged fasting can lead to all kinds of secondary health problems, some of which could eventually become life-threatening. You'd do much better switching to only eating fruits and vegetables if you are that desperate to lose weight. It's about as okay to go hungry for a long time as it is to consume a ton more calories than you strictly need. The only healthy way to attain your ideal weight is the golden rule that applies to everything: moderation.
