When you lose weight, where does it go?

Most people think we sweat out the weight when we lose it, burn it up into nothingness, or poop it out, but the truth is we breathe out the weight. I recently watch a super fascinating TED talk, which you can find here, about the chemistry of weight loss. Apparently, we’ve known since the 60s where the weight goes, but for some strange reason, nobody knows about it today.

If you don’t have time to watch the 20 minute talk on weight loss, which I highly recommend, then I’ll tell you all about it here.

Everybody wants to lose fat, not weight, fat. The goey blubber around our waist which makes us float, want to get rid of it? Well, okay, here’s how. We lose about 90% of our weight through our breath. When we exhale, we breathe out about 80% nitrogen, 15% oxygen and 5% carbon dioxide. That carbon dioxide is the good stuff, the stuff we want to breath out, that is us, our weight. But the trouble is, just breathing won’t get you to that slim 160 lbs. The reason is, if you just breathe, you are most likely exhaling food. Stuff in your digestion that is being broken down and used as energy, not fat. If you want to breathe out carbon dioxide from fat, there is 2 ways to do so.

The first is exercise. Run run run! Cardio is by far the best way to lose fat fast because long cardio sessions get you breathing and burning fat. When we raise our heart rate and use our muscles, our body reacts by sending a school of hormones into our system to break down fat and restore our glycogen levels. That means that if you are exercising often, you will be breaking down fat and breathing it out more often, instead of breathing out meal you just ate. “Burning fat” simply means, breaking it down and breathing it out.

The second way to break down fat and breathe it out is through ketosis. Ketosis is when the body is deprived of glycogen, and breaks down fat to replace the lossed sugar. Ketosis can attained through fasting, about 14 hours without food and you should start to break down fat and breathe it out.

The most efficient way to burn fat is a combination of both methods. Fasting and exercise, or moving more and eating less. Intermittent fasting, combined with exercise, can make you a lean-mean-fat-burning-machine. Huge plays.

Hustle it up!
