People Want To Know, How Does Fat Leave the Body?

how does fat leave the body

Have you ever thought about fat loss and how does fat leave the body?  Many people will say that the fat is burned off.  But how is it actually burned off?  Where does it go?

Real weight loss is fat loss that you achieve via proper nutrition and exercising.  A diet should include whole, natural, and even organic foods.  You want to supply your body with nutrients your body can readily use.  Proper diet combined with intense exercise is a recipe for fat loss.

But you are still asking, how does fat leave the body?

  • Do you starve the fat off?
  • Do you kill the fat with intense cardio?
  • Does the fat fairy come take it at night?

Where Does The Fat Go?

Ask any personal trainer about where the fat goes when you burn it off and you’ll likely get an answer such as, it’s converted to heat or energy, and just burned off.

Personal trainers are a dime-a-dozen, and most aren’t qualified to teach power walking.  Most read a few articles and forums and then market themselves as personal trainers.  Weight loss or fat loss is not a conversion, it’s a metabolic process.

What You Must Know

Fat is stored energy and your body uses is it in many ways.  Your body uses fat when you are at rest.  Even your heart uses the stored energy (fat) to pump your lungs so you can breathe.  Your brain also uses fat so you can think.  But that’s not all.  When you are active your muscles need energy.  In addition, when you are eating, your digestive system needs energy to break down the food to be used or stored for later.

As you can see, fat is necessary, to some degree, for your entire basal metabolism.  So, before you try removing every ounce of fat from your body, know that you do need a certain amount of fat just to live and have your body function.

Diet and Exercise Conversion – Fat to Energy

When you diet, you eat fewer calories than your body needs. This deficit causes your body to turn to fat reserves for energy.  During the process, the body converts fat into usable energy for your muscles and other tissues causing the fat cells to shrink.

When you exercise, your muscles burn through stored glycogen for energy first.  Usually, after 30-60 minutes of aerobic exercise your body has burned through the stored glycogen and starts burning primarily fat.

How Does Fat Leave the Body?

Most people don’t even think about where the fat goes.  They are just happy the scale is down and they fit into their clothes.  But, what fat loss is, is really a byproduct of waste.

You see, it’s not about starving yourself or overexercising.  It’s about nutrition of course, but also breathing.  Most of the fat mass is exhaled in the form of carbon dioxide.

In the British Medical Journal, Professor Andrew Brown, head of the UNSW School of Biotechnology and Biomolecular Sciences and Ruben Meerman, a physicist and Australian TV science presenter conducted a study and found:

  • 22 lbs (84%) of fat are fully oxidized, 18.5 lbs of fat departs through your breath as carbon dioxide
  • 3.5 lbs (16%) drains out as H2O (urine, sweat, feces, breath, tears or any other body fluid)

As you can see, your lungs are the primary expiatory organ for fat.
