When You Burn Fat, Where Does It Go? | The Sisterhood of the Shrinking Jeans LLC


You are constantly burning calories – sleeping, sitting at work, chasing your kids, chasing your dog, or getting in a good sweat session. Your body does it naturally, sometimes at a faster rate than others. And, when you burn more calories than you consume (at the basic level), weight loss occurs. Every pound is the equivalent to 3,500 calories – so to lose one pound, you need a 3,500 calorie deficit.

Something interesting happens, though, when you burn fat. Where does it go? I saw this short video on Greatist earlier this week and couldn’t resist sharing. A survey of doctors, dietitians and trainers revealed that the majority of them believe that when you burn fat, fat converts to energy and is released as heat; however, a recent study shows that fat is released as carbon dioxide when we exhale. Their conclusion: when you burn fat, you breathe it out. It can also be lost through sweat, urine and tears, but as a much smaller percentage.

It sounds simple, but there’s actually a lot more behind it. Check out the video by SciShow above to get the chemistry details.

Just keep this in mind when you’re completing the 10K-a-day + push-ups and squats monthly fitness calendar!
