Losing weight seems like a must-do for everyone in a lifetime nowadays.  However, few people ever wonder where the weight we lost has gone.  Up to 98% of doctors, nutritionists and fitness gurus aren’t even able to answer the question.  Most of people think that the fat transfers into energy, but it actually violates the conservation of mass; some guess the fat would become muscles, which is impossible, and some imagine it excretes out of the body, which is also nonsense.  Then, where has the fat exactly gone?

Both the Australian scientist Ruben Meerman, who writes the book Big Fat Myths: When You Lose Weight, Where Does the Fat Go, and professor from The University of New South Wales Andrew Brown have been confused by this question, so they asked up to 150 health experts, and it turned out that only 3 people could answer correctly – the fat converts to carbon dioxide and water.  We breathe out the former, and the latter goes into circulatory system, excreting as urine or perspiration.

If you lose 4.5 kilograms of fat, then about 3.8 kilograms of it is expired by lungs, and the rest 0.7 kilogram transfers into water.  In other words, almost all the weight being lost was expired by ourselves.  Besides all kinds of carbohydrate you digest and almost all of fat, alcohol also converts to carbon dioxide and water.  Most of protein dose the same way, and a little of protein converts to urine.  Among all kinds of food, only fiber comes to the colon without digestion.

For instance, if 2.8 kilograms of fat is to be metabolized, it will consume 8.2 kilograms of oxygen, and then produce 7.9 kilograms of carbon dioxide and 3.1 kilograms of water.  However, what it is calculated above does not contain the consumption of food. Thus, if 2.8 kilograms of fat is to be lost, in addition the expiration of carbon dioxide which is produced during metabolizing food, there is extra 7.9 kilograms of carbon dioxide should be expired.

Taking American as an example, according to the latest survey, an adult consumes 3.55 kilograms of food and beverage every day, yet the report does not mention that an adult also inhales more than 660 grams of oxygen.  Therefore, unless excreting 4.2 kilograms, otherwise people gain weight.  Most of American’s daily consumption of carbohydrates, fat, protein, and alcohol produce 770 grams of carbon dioxide, 290 grams of water and about 31 grams of urine.  After falling asleep, 200 grams of carbon dioxide will be expired.

Since the fat will convert to carbon dioxide, is that means the more we breathe the more weight can be lost?  Sorry, it’s not going to happen.  Breathing too much is called hyperventilation which cause people extremely dizzy and even to fall down in a faint.  Only exercising muscles can effectively increase the amount of carbon dioxide that the body produces.  Like strolling, cooking and sweeping increase three times metabolic rate.
