Difference Between Calories And Fat (With Table)

People often think calories and fat are under the same line. Knowing the difference between how calories and fats can function and where they get stored in our body can make a huge change in our food consumption pattern. 

Calories vs Fat

The main difference between calories and fat is that a calorie is nothing more than a measurement of energy. It is the approximate quantity of energy your body may receive by digesting food in the context of food while fat is a nutrient that is classified as a macronutrient. Your digestive system can process fats, as well as carbohydrates and proteins.

A calorie is “a standard unit of measurement for the amount of energy required to raise the temperature of water by one degree Celsius,” according to the Merriam-Webster definition. To get our daily calorie intake we can divide your daily food consumption by six and multiply the quotient by 1000.

The accumulation of surplus, unused lipids (fat) within the adipose tissue is known as fat (the tissue that stores excess fat). It arises as a result of a series of chemical events in the body’s normal cells to store fats that aren’t being used to store the fat right now. 

Comparison Table Between Calories And Fat

Parameters of Comparison




Heat energy or unit energy is known as calories. In other words, calories are the amount of heat or energy required at 1 atmosphere to raise 1 gram of water.

Naturally oily substances that are deposited underneath the skin as a layer around some organs and are primarily found in the tissues of animals and plants are known as fats.

Intake per day

For women from 1600 to 2400 and men between 2000 and 3000.

Ideal and recommended fat intake per day should be between 44 grams and 77 grams.


The digestion part and absorption happen in the digestive tract and this process of absorption is known as metabolism.

A major part of digestion happens only when the fat reaches the small intestine.


There are two categories of calories and they are small calorie and large calorie.

Fats are categorized into four and they are saturated fat, unsaturated fat, trans fat, and total fat.

Food groups

The food groups that have major calories sources are corn, beans, potato, etc.

The food groups that have major fat sources are butter, ghee, cream, cakes, biscuits, pastries, etc.

What Are Calories?

Food is broken down in the body by mixing it with oxygen, as we all know. It is burned up like fuel up to your will. This burning method is also used to calculate how much work a fuel does.

The amount of heat required to raise the temperature of one gram of water by one degree centigrade is called a “gram calorie.” 

The difference between the “big calorie” and the “little calorie” is 1,000 times. The huge calorie is commonly used to determine the energy value of food.

Each food provides a specific quantity of calories as it “burns up.” One gram of protein, for example, has four calories, whereas one gram of fat contains nine.

The body doesn’t mind which type of energy is used as long as it gets enough of it from food to stay alive. The amount of calories required by the body is determined by the amount of effort performed. 

For example, if a man weighs 150 pounds and is completely at rest, he only needs 1,680 calories per day. 

This increases to 2,360 calories per day if he works moderately during the day. And if he works hard, he can need as many as 5,720 calories every day to keep his body running smoothly. 

Because children are developing and burning a lot of calories while playing, they require more calories than adults.

What is Fat?

In biological substances fats are commonly known as oils and lipids.

Saturated and unsaturated fats can be found in a variety of meals, including proteins, carbohydrates, and dairy products.

Unsaturated fats are those with one or more double-bond chemical structures in their fatty acid chains.

These are the two different forms of unsaturated fats:

Mono-saturated: One double bond having two elements between them is known as mono-saturated fats.

Poly-saturated:  These fats are thicker and have a double bond. The food groups that contain these fats are fish, legumes and nuts, etc. 

They appear to be healthy since they reduce the risk of heart disease and are an important part of a well-balanced diet.

Another type of fat is a trans fat that is hydrogenated plant oils that are used to create synthetic fats.

They are found naturally in several foods, such as milk, and they are frequently connected to major heart risks and health problems like liver dysfunction, heart disease, obesity, and cancer. 

Cooking oils for fast food restaurants and fat substitutes are common applications.

Fats that are high in saturated fats have double bonds or are hydrogen “saturated” chains. Animal fat contains them. Cancer and other disorders have been linked to them. 

When it comes to fats, it is best to go for the healthier option. Polyunsaturated fats have been demonstrated to be healthier in general.

Main Differences Between Calories And Fat

  1. Calories have pre-SI metric energy units whereas fats have fatty acids esters.
  1. The extra calories will be stored as body fat and extra fat will not be stored and will leave our body through the skin, kidneys, and lungs.
  1. Calories are broken down with the help of a food processing method also known as thermogenic while fats are broken down in the human body with the help of enzymes.
  1. The human body needs calories for the basic process and survival. On the other hand, the human body requires fat to support cell growth.
  1. Calories are quickly converted as fat within four to eight hours and fat is quickly formed in our waistline in less than four hours.


Our bodies get fuel from the food we eat. We require those calories but in insufficient quantities. 

If we consume too many calories, we risk gaining weight and becoming obese, which is a precursor to all of the health problems that come with obesity.

If we consume too much fat then it can raise our cholesterol levels and can increase the rate of our heart disease.

Too much of either is dangerous. Every food item has a certain amount of calories that provide energy and gets metabolized by the body and on the other hand, fats are indissoluble in water. Few fatty-based foods have calories but not all calories have fats.
