It all really depends on how long you wait with food in your body before purging. It takes 1 to 4 hours for food to move past your stomach. You do not absorb nutrients or calories until your small intestine.
No.
Calories are not typically absorbed in the mouth. Most if not all calories of a particular substance are absorbed in the stomach.
Purge-- To rid the body of food and calories, commonly by vomiting or using laxatives.
Once food has reached that point, all of the calories have been absorbed. You don't get rid of the calories when you use the bathroom (be it naturally or by using laxatives).
Calories are not absorbed anywhere in your body. They are, however, burned. We ingest food which has a caloric content, but it is only when the food is digested and absorbed by our digestive tract, mostly in the small intestines, that it becomes available for our cells to use in metabolism. So, in a way, you could say that calories are absorbed in the small intestine, but they are not counted as calories until they are used, either for energy or for storage.
Any amount of purging is dangerous. The act of purging can cause death due to heart irregularities and electrolyte imbalances.
No, only through what you eat.
Not really. Once everything you eat gets to that stage, most of the calories have been absorbed into your body .
To transform 1 gram of ice at 0 degrees Celsius to 1 gram of water vapor at 100 degrees Celsius, 720 calories are added (absorbed). There are no calories released during the process.
Not as many as you think. Especially if you binged on sweets: your body absorbs those calories very fast. Purging makes you look like a washed-up drug addict. It ruins your complexion and your teeth, and makes your eyes look hollow. No matter how thin you are, toothless and grey-faced is NOT a good look.
No, there is no other way to get rid of the calories you consume than to exercise or at least moving your body. It is never recommended that you purge laxatives.
