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.
The percentage of alcohol that is absorbed through the small intestines is 80%. The remaining 20% of alcohol consumed is absorbed through the stomach.

Cheese is mainly composed of lipids and proteins. Proteins are digested in the stomach and small intestines and absorbed in the small intestines. Lipids are emulsified by bile in the duodenum and absorbed later in the small intestines. The only thing in cheese that makes it to the large intestines is the moisture, but most cheeses do not have a large water content.
Nutrients are absorbed by the blood vessel in the small intestines. Special cells in the small intestines are facilitate this movement.

It depends on whether the food has reached your small intestines or not. If you want to control calories it is much healthier to stick to a balanced diet and to exercise. Purging can damage your esophagus as well as your teeth because of the acidic contents of your stomach that aid digestion.
