Where Does the Fat Go?

From Conservation Of Massive: When You Lose Weight, Where Does The Fat Go?

Lots of people say they care about their weight, and there is no end to weight-loss schemes available on websites, but if you ask nutritionists, personal trainers and even some doctors where fat goes when people lose weight, they can’t tell you the right answer.

Caveat emptor.

The most common misconception is that the missing mass has been converted into energy or heat. It’s physics, after all. Except it isn’t, not in the way they think it is. To lose 10 kilograms of fat requires 29 kilograms of oxygen for the body and that metabolic process produces 28 kilograms of carbon dioxide and 11 kilograms of water. It didn’t convert to energy, you didn’t “burn” fat.

“There is surprising ignorance and confusion about the metabolic process of weight loss,” says Professor Andrew Brown, head of the University of New South Wales School of Biotechnology and Biomolecular Sciences.

“The correct answer is that most of the mass is breathed out as carbon dioxide. It goes into thin air,” says the study’s lead author, physicist Ruben Meerman, who became interested in the biochemistry of weight loss through personal experience. “I lost 15 kilograms in 2013 and simply wanted to know where those kilograms were going. After a self-directed, crash course in biochemistry, I stumbled onto this amazing result. With a worldwide obesity crisis occurring, we should all know the answer to the simple question of where the fat goes. The fact that almost nobody could answer it took me by surprise, but it was only when I showed Andrew my calculations that we both realised how poorly this topic is being taught.”

It’s rather interesting. You’d think that it was basic science, but half the professionals didn’t know the right answer!

Neither did I, actually, but at least I asked around on the ‘net, and found out the truth…

Lesson learned: Christians should not presume to know all the answers. God expects us to get up and find out!
