Where All The Fat Goes After Weight Loss?

What is happening with fat after weight loss?

Weight loss is a bit of challenge and hard work is most important for reaching the goal. With 69 percent of Americans struggling with obesity or other health problems related to overweight, a lot of people are trying to drop some pounds every day.

You have started to work out. After a few weeks of trimming calories, exercising more, riding a bike, running, going to the gym more often, taking pills, sticking to your diet, or you are starving yourself, your belly fat is missing. Well, at least some part of it.  But we all wonder, what is happening with fat after weight loss?

While some may think that fat layers dissolve and transform into energy, heat all muscles, scientists found a slightly different answer.


The Australian scientist Andrew Braun published his calculation for exact values how much fat turns into something different in the “Britain Medical Journal”. Ruben Meerman said – “Correct answer is that most of the fat we breathe out is carbon-dioxide and it goes with the wind”. He is a physicist and he worked with Braun during the research. They published this research, using their knowledge in biochemistry.

Carbs and proteins are converted into triglycerides which consist of carbon, hydrogen, and oxygen and then are stored in the lipid droplets of fat cells. If you want to lose weight, your body needs to metabolize those triglycerides and unlock the carbon which is locked in fat cells.


For example, if you want to lose 20 pounds of fat layers, you need to inbreathe 58 pounds of oxygen, after which 56 pounds of carbon-dioxide and 22 pounds of water will be produced. An average man should breathe in and out for 33.000 times, and an average woman for 50.000 to enter the required amount of oxygen. So, the lungs are the most important excretory organ for weight loss – interesting, isn’t it?

Fat leaves your body as a carbon dioxide when you breathe out. Braun and Meerman claim that if you lose 20 pounds of fat – 16.8 leave your body as carbon dioxide. The remaining 3.2 pounds turn into the water which is excreted as urine, feces, tears and sweat.


If you are still not sure about the answer, it helps to remember that fat is basically stored energy. Your body converts fat to usable energy for your muscles and other tissues through a series of complex metabolic processes. This is the main reason why your fat cells shrink. During this complex metabolic processes, your body produces waste. These waste products are water and carbon dioxide and they are excreted in your urine and sweat or exhaled from your lungs.

I know that you are wondering if that means that you simply need to exhale more to lose weight? No! Breathing more than your body requires can cause hyperventilation and loss of consciousness.  Lower calorie meals and more training are still the best ways to stay healthy, beautiful and in a good shape.

So what stops you from exercising right now?
