Carbohydrates start to break down in the mouth due to the presence of an enzyme called salivary amylase found naturally in saliva. The carbohydrates are further broken down in the stomach and small intestine. Fats are broken down in the stomach and small intestine with the help of enzymes secreted from the pancreas, gall bladder, liver, etc.
Mouth?
The digestion of fat will begin in the small intestine, whereas the digestion of starch which begin in the mouth (the mouth contains the enzyme amylase, which helps break down starch)
Digestion breaks down fat, carbohydrates, and protein into smaller molecules that can be absorbed by your GI tract. Without it, no absorption --> malnutrition --> death
Fat is burned into carbohydrates yes.
Macromolecule digestion typically begins in the mouth with the breakdown of carbohydrates by amylase. Further digestion of macromolecules like proteins and lipids occurs in the stomach and small intestine with the help of various enzymes such as pepsin and pancreatic lipase.
Carbohydrates can be converted into fat in the body, but this process is not very efficient. The body typically uses carbohydrates for energy first before converting them into fat. Consuming excess calories from any source, including carbohydrates, can lead to weight gain and fat storage.
The mouth is important because that is the first place where food is mechanically chewed up before it reaches the stomach. It also is mixed with saliva which makes it moist and carries amylase an enzyme that begins the breakdown of carbohydrates,
The body prioritizes burning carbohydrates for energy first, then fat, and lastly protein.
drain the fat
When you intake excess carbohydrates than you required it is turned to fat. Not only carbohydrates, proteins will also turns to fat if taken in excess. But there are times when carbohydrates won't change to fat. These are post workout meal and breakfast.
carbohydrates are the first source that is used by the body during fasting ,second is fat and then protein
Excess carbohydrates are stored as fat.
