💨 Where Does the 'Fat' Go When You Lose Weight?
When you lose weight through dieting, the fat in your body magically disappears. Many people think that fat simply turns into 'energy or heat' and vanishes. In reality, fat becomes a physical substance that completely exits your body.
1. 84% of Fat Leaves Through Your 'Breath'
Surprisingly, most of the fat we burn is excreted through the lungs in the form of carbon dioxide ($CO_2$).
- Fat cells are broken down and released into the bloodstream.
- They combine with oxygen and undergo an oxidation (combustion) process.
- The end product, carbon dioxide, is exhaled out of the body when you breathe out.
When we exercise or fast, the reason we breathe heavily is a sign that we are expelling more fat as carbon dioxide.
2. The Remaining 16% is Excreted as 'Water'
The remaining fat components that don't turn into carbon dioxide transform into the form of water ($H_2O$).
- Sweat: Sweat produced during exercise.
- Urine: Waste excreted through the kidneys.
- Tears and other bodily fluids.
What we commonly say, "Sweat is the tears that fat cries," has some scientific basis.
3. The Departure of Fat in Chemical Formula
A large amount of oxygen is required to completely break down fat ($C_{55}H_{104}O_6$). This process yields the following results:
- To lose 10kg of fat? You need to breathe in about 29kg of oxygen, resulting in the production of 28kg of carbon dioxide and 11kg of water, which are expelled from the body.
In other words, losing weight is chemically the process of exhaling the carbon in your body into the air.
4. How Intermittent Fasting Helps This Process
Intermittent fasting creates the optimal environment for our body to better 'expel' fat.
- Increased Oxidation Efficiency: When insulin levels are low, fat cells are more easily broken down and ready to be excreted.
- Smooth Water Metabolism: Sufficient water intake during fasting helps the smooth excretion of fat in the form of water after it is broken down.
To Summarize?
The whereabouts of the fat that has left your body are as follows:
- 84% (Most): Excreted as carbon dioxide when you exhale.
- 16% (Remaining): Excreted as water, such as sweat or urine.
Fat doesn't just disappear; it gradually flows out of our bodies in every moment we breathe and sweat.
