Are you the kind of person who prefers to stay away from fatty foods, just for the sake of being healthy? Well, certainly you need to know something crucially. Of course, the perception is not your fault. In recent decades, it became a myth that a fat-rich diet is unhealthy. Maybe to some extent, it is true, but not always. Your body needs some amount of fats significantly. Fats play a pivotal role in the overall body’s mechanism. In case, if you try to avoid fats completely in your diet, then you are making the biggest mistake ever for your health and well-being. 

The role of fats in the body:

You need to have no more than 30 % of the total calories of fats per day. However, this 30 % is the daily dietary allowance for healthy welfare. Just like proteins and carbohydrates, fats are also a main component of macronutrient. Making your diet a fat-free or ultra low-fat diet, will, in turn, cause many detrimental effects. An optimum level of Fat is typically important for major function. 

Fats are the storage form of energy:

Your body needs energy for everything. Not only for the moving or lifting purpose, but your body also needs energy for the function of internal organs. Every cell requires energy to play its role. Carbs are instant energy givers. However, when you don’t have adequate carbs, just like the time of fasting, or situationally you tend to miss a meal, fats take up the role to maintain all the functions undisturbed. Triglycerides are the neutral fats, that are stored in the body as a form of energy. It breaks eventually to supply energy whenever your body needs it. 

Fats are the structural component of the cell membrane:

We all know that our body is nothing but a huge pack of cells. Every cell has a cell membrane that helps to maintain the integrity of the cell structure. These cell membranes are made of phospholipids and cholesterol. Without fats, it is impossible to maintain the cellular structure. 

Metabolic regulator:

Fats are extremely important for the synthesis of the most important hormones like steroids and prostaglandins. They are necessary to control inflammation, to maintain body mass index, for reproductive function, to control allergies, to regulate metabolism, to maintain body temperature, for proper DNA synthesis and genetic functions. 

Fats acts as an emulsifying agent:

The surfactants are necessary to lower the surface tension, particularly in the lungs. Without the surfactants, the alveoli will stick to each other. Whatever you breathe, your lungs cannot process the same. These surfactants are made of fats and proteins. Without fats, it is impossible for the alveoli to exchange oxygen to the body

Fats acts as an electric insulator:

Neurons transmit signals in the form of electric ions in the body. The neural structure has fat-containing cells that regulate the ionic movements. This insulation helps to increase the rate of transmission of signals. These flow of electrons are not only significant for the function of the brain and neural system. From the movement of muscles to the functioning of the heart, every action takes place through an ionic flow. Thus, every internal organ is safely insulated because of fats. 

It provides insulation against external temperature:

The subcutaneous fat deposits extremely help to maintain the internal body temperature irrespective of external temperature variation. The inner body temperature has to maintain ideally without fluctuations. Even the  0.1 variations of heat inside the body will drastically affect the health of internal organs. 

Gives shape and contour to the body:

Proper contouring of the body will only happen with the right deposition of fats at the right places. The excessive or limited deposition will certainly alter the ideal shape. 

For the absorption of fat-soluble vitamins:

Vitamins A, D, E and K absolutely require fat for their absorption. These vitamins extremely need to increase bone strength, for improving the vision, for maintaining the blood clotting mechanism and to protect the internal organs from the free radicals. 

Fat improves the taste and palatability of food:

Without fat, the food is bland and plain. If you are a foodie, then definitely you will understand what I mean here. You need at least some amount of fatty stuff to add flavour to the diet, to make it palatable. 

What happens if you avoid fats completely:

  • You will become extremely weak, fatigue, skinny and unhealthy
  • Your skin becomes extremely dry and flaky
  • Your body cells start to undergo autolysis and dead
  • You will have trouble breathing. Your body does not get adequate oxygen. Depleted oxygen levels will have a serious impact on the vital structures. It is not uncommon to die, in case, your body doesn’t carry enough oxygen. 
  • Too much or very little fats in the body will definitely cause hormonal imbalance
  • You are prone to harsh free radical damages. From ageing to cancer, free-radicals are responsible
  • Uncontrolled bleeding
  • You will lose cellular integrity
  • Bones become extremely fragile, soft and easily breaks
  • Risk of blindness
  • Unpredictable and undetermined brain activity. Major imbalance in the emotions, cognitive skills, behaviour and neuroendocrine functions
  • The uncontrolled fluctuation of internal body temperature, which risks your life, once for all.


Zero fat diet will never be a supporting factor for your well-being. You certainly require some amount of fat in the body to function properly. It is not denied that too much of fatty deposits are unhealthy. Equally, too low fats in the body are also unhealthy. Balancing your daily dietary intake will add more value to your health and happiness.
