fats are more complex than other forms of carbohydrates so it take more energy for the body to break them down, so generally if it doesn't need to it doesn't break them down if your body needs the energy it will break down the fats
Dietary fats are marginally more difficult to digest than dietary protein and so will take slightly longer. Withinthe digestive tract the fats are only starting to be digested in the duodenum once the bile has been added whereas almost all of the protein digestion has taken place already in the stomach. Under conditions of starvation however fat is used up first as it is stored, is largely useless and has huge ammounts of energy. Protein will be the last thing to be scavenged here as it is very difficult to break down in the body and provides less energy.
Both fats and protein is essential for the human body. Carbohydrates are not essential. So the answer is protein and fats.
your body needs fat so that it can be broken down to use energy.
Lipase is an enzyme (catalyst) so it speeds up reactions (in this case the breakdown of fats into fatty acids and glycerol).
Fats are called the energy banks of the body because the body uses fat to create energy. The fats can be used to create heat and energy, to insulate the organs and nerves inside the body, and to regulate the fat soluble vitamins.
Bile helps to break down fats in the digestive system into smaller molecules so that they can be more easily absorbed by the body. It also aids in the absorption of fat-soluble vitamins like A, D, E, and K.
because its is from the body so it hav all of the above
Fats are a concentrated source of energy, provide essential fatty acids, aid in the absorption of fat-soluble vitamins, and help protect and insulate organs. They also play a vital role in cell membrane structure and hormone production.
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.
you can excerise more try not to eat so many foods with a lot of saturated fats and make surre that you eat healthy but also so remember some fats are good for you because our body does need fat .
Trans (partially hydrogenated) fats can increase unhealthy cholesterol and lower healthy cholesterol. This can increase your risk of heart disease. See also:More informationEating healthily
