What happens to fat when you lose weight?

24/12/2018 Weight Loss

You must’ve heard countless times that you ‘need to burn fat’ or ‘get rid of fat to lose weight’ but have you wondered where does fat go?

Exercising helps you burn calories and get rid of the excess fat your body has. In this article, you’ll find out the answer to this popular question:

Where does fat go?

Your body needs fuel to function. Whether it’s for doing a set of push-ups or for making your heart beat, it requires fats and carbohydrates to act as fuels for its day to day operations. When you’re planning on losing weight, you need to burn this fuel.

Most of your fat is burnt into the air (Shocking, right?). Out of the total body accumulated in your body, 84% of it is expended by your body in the form of carbon dioxide (CO2). You release carbon dioxide whenever you exhale.

The rest of the 16% of the fat is released by your body in the form of urine and other excretions. Just as a car engine converts the petrol (or diesel) into smoke, your body converts the accumulated fat into gas.

Where do you gain fat?

In the bodies of younger women, fat gets accumulated around buttocks, breasts, thighs and hips. The fat is distributed all over the body but in the younger ages, these areas store more fat than the other areas. After (and during) menopause, the fat begins to accumulate around the abdomen.

There’s a huge difference between gaining weight and fat. You can increase your weight by gaining muscle too and that makes a big difference. That’s because building muscle is healthier. It uses energy whereas fat will only increase the stored energy in your body.

You’ll gain muscle if you are doing strength training and eating protein. On the other hand, you’ll eat fats if you’re consuming more calories than you burn in a day.

What are the different types of fat?

There are two types of fats that are stored in your body they are white fats and brown fats. Both of them are described below:

White Fats

The most common form of fat is white fat. It is used as ‘stored energy’ in your body. Another prominent function of this fat is to insulate and pad your body, protect the vital organs and aid to maintain your body temperature.

The amount of white fat in your body can show how healthy you are. The American College of Sports Medicine recommends women to have a fat percentage from 20% to 32%. It influences your BMI (body mass index) as well.

If you want to check how healthy your body is, you should check the fat percentage, cholesterol and other vital indicators.

The White Fat is also of two kinds:

Visceral Fat:

 It is stored deep within your body’s abdomen. It is placed close to the vital organs of your body such as liver and kidneys. However, it makes the job of these organs difficult as it occupies free space.

Women don’t face many problems with this fat. But it is responsible for causing heart problems and its excessive quantity can lead to many other complications. It is metabolically active and it promotes insulin resistance.

Subcutaneous Fat:

While visceral fat is deep within the body, subcutaneous fat is present beneath the skin. It is not as harmful as visceral fat but too much of it can lead to some problems. Its function is to insulate the body and protect it.

It adds weight to your body, which can lead to problems related to the heart and circulatory system.

Brown Fats

Brown fat derives heat from the food you consume. It burns calories and that is why many experts call it ‘the good fat’. White fat acts as energy storage and brown fat act as an energy converter.

It is abundantly present in infants and children. As we grow older and become adults, we tend to lose this fat. Studies have shown that we can convert white fat into a fat similar to brown fat, called beige fat.


Now you know where fat goes when you lose weight and when you gain weight. Fats are essential for your body and even on a diet, you should try to eat good fats. They are the fuel for your body which provides it with the energy to operate.
