What functions do fats serve in your body?
What You Need to Know
- Fats have had so much “bad press” that many people forget that they are absolutely needed for life.
- Body fat provides the most important reservoir of stored energy as adipose tissue.

What are fats and what role do they play?
Fats give you energy, and they help the body absorb certain vitamins. Essential fatty acids help the body function, but they aren’t made by your body—you have to consume them.

- Fats and oils do not mix with water.

Triglycerides , cholesterol and other essential fatty acids—the scientific term for fats the body can't make on its own—store energy, insulate us and protect our vital organs.

What enzyme breaks down triglycerides?
When we need extra energy-for instance, when we run a marathon-our bodies use enzymes called lipases to break down the stored triglycerides. The cell's power plants, mitochondria, can then create more of the body's main energy source: adenosine triphosphate, or ATP.
What is the function of cell membranes?
Cell membranes encase our cells and the organelles inside them. Fat—specifically, cholesterol—makes these membranes possible. The fatty ends of membrane molecules veer away from the water inside and outside cells, while the non-fatty ends gravitate toward it. The molecules spontaneously line up to form a semi-permeable membrane. The result: flexible protective barriers that, like bouncers at a club, only allow the appropriate molecules to cross into and out of cells.

How does the body regulate cholesterol?
Dietary cholesterol helps to maintain a stable pool of cholesterol, but cholesterol is also synthesised by the liver. The human body regulates its cholesterol status. When the cholesterol intake is very low (as in vegans who consume no animal products), both gut absorption and synthesis increase. When cholesterol intake is high, the body's synthesis is suppressed and excretion via bile salts is increased. The amount of cholesterol, which passes daily through the small intestine, which is the sum of dietary cholesterol and produced cholesterol, is between 1 and 2 g. 2 The average cholesterol intake in Europe is 200-300 mg/day, meaning that the body’s production is significantly higher. The blood cholesterol level is the net result of the absorption in the gut and the synthesis in the liver, minus the excretion via the faeces (as cholesterol, bile salts and products resulting from bacterial transformation) and the use of cholesterol by cells. 4
What are the structural components of the cell?

How does fat help the body?
Fats help the body to produce and regulate hormones. For example, adipose tissue secretes the hormone leptin, which signals the body’s energy status and helps to regulate appetite. Fat is also required for reproductive health; a woman who lacks adequate amounts may stop menstruating and be unable to conceive until her body can store more energy as fat. Omega-3 and omega-6 essential fatty acids help regulate cholesterol and blood clotting and control inflammation in the joints, tissues, and bloodstream. Fats also play important functional roles in sustaining nerve impulse transmission, memory storage, and tissue structure. Lipids are especially focal to brain activity in structure and in function, helping to form nerve cell membranes, insulate neurons, and facilitate the signaling of electrical impulses throughout the brain.

What is the energy that is stored in the body?
Most of the energy required by the human body is provided by carbohydrates and lipids. As discussed in the Carbohydrates unit, glucose is stored in the body as glycogen. While glycogen provides a ready source of energy, it is quite bulky with heavy water content, so the body cannot store much of it for long. Fats, on the other hand, can serve as a larger and more long-term energy reserve. Fats pack together tightly without water and store far greater amounts of energy in a reduced space. A fat gram is densely concentrated with energy, containing more than double the amount of energy as a gram of carbohydrate.
