Weight loss happens via breathing, according to a recent study. The Australian University of New South Wales researchers wanted to know where fat went during dieting. All findings were published in The BMJ’s Christmas issue.
While weight loss is not on the top of everyone’s thoughts right now, it will become a major focus for many in the New Year. Many have resolutions that involve losing excess weight, especially the weight they have gained over the festive period. However, while many know that weight loss involves fat loss, it has always been a question of where the excess fat goes. What does the body do with it when expelling it?
Even physicians, personal trainers and dieticians failed to explain what happened to the fat. According to Ruben Meerman and Andrew Brown, both part of the study, the personal trainers, doctors and dieticians have got it all wrong. Most believed that the fat would turn into heat or energy, but this goes against the conservation of mass law.
There was also the belief that the fat would convert to feces, and leave the body that way. Others believed that it was turned into muscle. It turns out that the body breaths the fat out, converting it into carbon dioxide. So, in effect weight loss happens via breathing.
Weight gain occurs when people eat more calories than their bodies need. There are a number of diet plans out there that encourage a calorie deficit, some more dangerously than others. However, the plans have never gone into what happens during the process.
According to the study, someone who weight 70kg will expel 200ml of carbon dioxide gas in a minute with 12 breaths. It turns out that each breath has just 33mg of carbon dioxide, and 8.9mg of that is carbon. So, 200g of carbon is expelled from the body throughout the day, and a third of weight loss can happen during sleep, assuming a person sleeps for eight hours.
The carbon is placed back into the body through food and drink. The authors of the study state that weight loss is possible by consuming less carbon than being breathed out during the day. This carbon loss can also be increased through exercise. With just one hour extra of moderate exercise, a extra 20 percent of carbon can be expelled from the body. However, unhealthy food choices will have an effect.
This is something that many people who try to lose weight are used to hearing. The difference is that carbon is the term rather than calories. Either way, moving more and eating less is the way to lose weight, especially when a healthy and balanced diet is concerned. The strategies for losing weight should not be changed with this new information.
The findings do support findings from earlier in the month. The Journal of Pediatrics included a study that showed childhood obesity was doubled due to sleep-related breathing problems and chronic lack of sleep. It shows that weight loss is certainly linked to breathing somehow, and that is just how the fat is expelled from the body.
